South Australia to build World’s biggest Solar Thermal Plant. #auspol 

South Australia Will Be Home to the World’s Biggest Single-Tower Solar Thermal Power Plant
South Australia has approved the biggest solar thermal power plant of its kind in the world. The 150-megawatt structure received the green light from government officials this week. The plant will be constructed in Port Augusta. 

The project will provide employment for over 600 construction workers and will provide more than enough energy for the state’s requirements.

Project expects to be running by 2020
The renewable energy project will kick off next year and be completed by 2020. 

The US$510 million project is the latest in a long line of renewable energy projects the state is tackling.

 Wasim Saman, from the University of South Australia, explains “The significance of solar thermal generation lies in its ability to provide energy virtually on demand through the use of thermal energy storage to store heat for running the power turbines.”

 He adds, “This is a substantially more economical way of storing energy than using batteries.”

The most common form of solar power uses solar photovoltaic panels to convert sunlight directly into electricity. 

This method of energy production then requires batteries to store the excess power.

 Solar thermal plants on the other hand use mirrors to concentrate the sunlight into a heating system. 

The method of heating can vary but for the South Australian plant, molten salt will be heated up.
This is a much more economical method than using regular batteries.

 The hot salt is then used to boil water, spin a steam turbine, and generate electricity when required.
Designers of the Port Augusta project say that the plant will have the ability to generate power at full load for up to 8 hours after the sun’s gone down.

 The South Australian project will be modeling itself off another big solar thermal power plant. 

The 110-megawatt capacity Crescent Dunes plant in Nevada was built by the same contractor who will use the US model as the base.

South Australia leading the way in renewables.
South Australia is a world leader in renewable energy. 

This latest project now means that around 40 percent of the state’s entire electricity needs are generated by renewable sources. 

It is hoped that the conversion to solar will also mean a cut in residential electricity costs. 

The new plant costs less than building a new coal-fired power station and works out to a similar cost per megawatt as other renewable sources such as solar and wind power.

Challenges still lie ahead
It isn’t all happy news though. 

South Australia was plagued by electricity blackouts last year and the unreliable renewable sources were blamed. 

Engineering researcher Fellow Matthew Stocks, from the Australian National University, says we still have “lots to learn” about how solar thermal technologies can fit into an electric grid system. 

He explains, “One of the big challenges for solar thermal as a storage tool is that it can only store heat. 

If there is an excess of electricity in the system because the wind is blowing strong, it cannot efficiently use it to store electrical power to shift the energy to times of shortage, unlike batteries and pumped hydro.”

A healthy diet can reverse the effects of fine-particulate matter, say experts

More than 90% of people worldwide have to breathe polluted air.

 Fossil fuels are the primary cause. 


The people most likely to suffer are those who live in crowded places where the shift to cleaner forms of transportation and energy has not happened or is happening too slowly. 

This is particularly evident in some areas of Asia, where smog hangs over cities and seeps into the countryside, and even into people’s homes.
Air pollution contains fine particulate matter that can enter the body and get into the lungs, causing respiratory and cardiovascular issues such as asthma attacks and irregular heartbeat, increased oxidative stress and inflammation, and chronic disease like diabetes and cancer.

 In fact, air pollution is responsible for more 7 million premature deaths worldwide, according to the World Health Organization: the single largest environmental health risk.


   

The only viable long-term solutions are accelerating the transition to a low fossil carbon economy and reversing climate change.

 But what can people do in the meantime to protect their health?
According to recent studies, your nutritional intake might come to the rescue. 

Researchers have found that good nutrition can fend off air-related illness and may even reverse the negative effects of fine particulate matter. If you’re one of the billions of people waiting for a breath of fresh air, that means you may want to up your vitamin intake.
Professor Jinzhuo Zhao, from Fudan University School of Public Health, China, who studies the impact of a particulate matter called PM 2.5 and explores nutritional solutions, says: “The findings of a number of human studies are encouraging and a good basis for further work to determine optimal combinations of nutrients to prevent or reduce the impact of particulate matter on different aspects of health.”
Some of the top nutrients thought to make a difference are long-chain polyunsaturated fatty acids like omega-3, as well as vitamins C and E. Oily fish like salmon is a great source of omega-3, which can reduce the risk of cardiovascular disease and stroke. Vitamins C and E, which are found in many fruits and vegetables, nuts and vegetable oil, are powerful antioxidants that help the body fight free radicals and restore its regular inflammatory response. For people who don’t get enough vitamins through food (and many of us don’t), supplements are a good source of health-boosting nutrients.
Of course, vitamins and omega-3 are only part of a solution. 

This does not reduce the responsibility of polluters, nor of law-makers and authorities who must legislate and enforce policies that stop pollution. 

It means that governments, scientists and the private sector should work together and continue research in this area because improving nutrition is easy and inexpensive, and it may be one way to help the billions of people who are waiting with bated breath, sometimes quite literally, for air pollution to stop.

5 Crucial skills to fight #ClimateChange #StopAdani #auspol 

Five Crucial Skills We’ll Need to Actually Fight Climate Change

A toolkit for saving the world.
This article has been sponsored by Griffith University for their new Bachelor of Social Science – find out more here.
Kevin Rudd described global warming as “the greatest moral challenge of our generation”, but this is too simple. It’s the greatest economic, political, social, cultural, environmental, and scientific challenge of our time.


A silver bullet won’t be found in a scientist’s laboratory, the halls of Parliament, nor a community activist’s meeting.
Nope, it’ll take a coordinated effort from researchers, corporations, politicians, innovators and communities to tackle climate change.
This is precisely why social scientists are poised to play such a crucial role. People with the breadth of understanding and skills to navigate and coordinate all of these moving parts will be absolutely crucial.
So with that in mind, here are five of the instruments in a social scientist’s toolkit that we’ll need to fight this real and present danger.
1. Research and innovation

Without technological transformation in some of the world’s biggest industries, we won’t stand a chance. 
Existing alternative energy sources such as solar and wind need to become more efficient, and fledgeling technologies like ocean, hybrid and bio energies need to develop to support ever-increasing energy demands.
New York Times columnist Thomas Friedman has famously framed climate change as an issue of economic competitiveness and innovation.
The countries and businesses that are more successful at producing new energy technologies and practices will thrive.
The rest will fall behind.
2. Data Analysis

It sounds dry, but data analysis strikes at the very heart of the climate change debate. The interpretation of global temperature data is the major flashpoint for the conversation, and so understanding and communicating this information will only become more important over time.
On top of this, big data is proving to be crucial in the response to global warming.
Microsoft’s mind-boggling Madingley project is a real-time virtual biosphere – ie. a simulation of all life on earth.
It creates a simulation of the global carbon cycle and predicts how it will impact everything from pollution to animal migration to deforestation.
3. Political leadership

Leaders with a deep understanding of socio-political structures and forces will be needed to enact change on a legislative and global level. 
The recent failure of the Paris Accord shows just how important negotiation and diplomacy will be in order to get countries from around the world to work together.
This not only involves political guile, but also communication skills, cultural knowledge and courage to make difficult but necessary decisions.
4. Corporate leadership

With this in mind, leadership in the corporate sector naturally has a massive role to play. Far swifter and more meaningful change can come from within a business than when it’s mandated by government regulations.
Business models will need to be forward-thinking, not relying on traditional methods of production, and change company cultures in the process.
A recent example of this sort of industry leadership is Volvo who announced they will cease production of purely internal combustion engine (ICE) vehicles by 2019.
5. Communication skills

Andrew J. Hoffman from the University of Michigan perfectly articulated the state of the “toxic” climate change debate:
“On the one side, this is all a hoax, humans have no impact on the climate and nothing unusual is happening.
“On the other side, this is an imminent crisis, human activity explains all climate changes, and it will devastate life on Earth as we know it. Amidst this acrimonious din, scientists are trying to explain the complexity of the issue.”
As a society we’ll need to reach some sort of meaningful consensus on the issue. From the boardroom to Twitter, we’ll need opinion leaders who can navigate the clashing world views that dictate how we view the science.
It won’t be easy, but it is necessary.
Clearly, climate change and many other global concerns are multi-faceted issues that necessitate a range of approaches and perspectives.
It’s for this very reason that Griffith University researcher Ben Fenton-Smith believes “there is no question that social scientists are going to be in huge demand in the next 20–30 years.”
“As our use of data, technology and information increases, we are going to need social scientists to make sense of it.”
Complex problems have complex solutions.
Griffith University is introducing a brand new Bachelor of Social Sciences to develop the next generation of Aussie leaders keen to tackle the biggest issues facing the world today. Head over here to find out about this exciting new degree.

Where does #ClimateChange denial come from? #auspol #StopAdani 

COMMENTARY: Where does climate change denial come from?
IDEAS-VOICES By Paul Krugman – 

Posted: 12:00 a.m. Sunday, August 13, 2017
“It’s Not Your Imagination: Summers Are Getting Hotter.” So read a recent headline in The Times, highlighting a decade-by-decade statistical analysis by climate expert James Hansen. “Most summers,” the analysis concluded, “are now either hot or extremely hot compared with the mid-20th century.”


So what else is new? 

At this point the evidence for human-caused global warming just keeps getting more overwhelming, and the plausible scenarios for the future — extreme weather events, rising sea levels, drought, and more — just keep getting scarier.

In a rational world, urgent action to limit climate change would be the overwhelming policy priority for governments everywhere.
But the U.S. government is, of course, now controlled by a party within which climate denial — rejecting not just scientific evidence but also obvious lived experience, and fiercely opposing any effort to slow the trend — has become a defining marker of tribal identity.
Put it this way: Republicans can’t seem to repeal Obamacare, and recriminations between Senate leaders and the tweeter in chief are making headlines. But the G.O.P. is completely united behind its project of destroying civilization, and it’s making good progress toward that goal.
So where does climate denial come from?
Just to be clear, experts aren’t always right; even an overwhelming scientific consensus sometimes turns out to have been wrong. And if someone offers a good-faith critique of conventional views, a serious effort to get at the truth, he or she deserves a hearing.
What becomes clear to anyone following the climate debate, however, is that hardly any climate skeptics are in fact trying to get at the truth. I’m not a climate scientist, but I do know what bogus arguments look like — and I can’t think of a single prominent climate skeptic who isn’t obviously arguing in bad faith.

Take, for example, all the people who seized on the fact that 1998 was an unusually warm year to claim that global warming stopped 20 years ago — as if one unseasonably hot day in May proves that summer is a myth. Or all the people who cited out-of-context quotes from climate researchers as evidence of a vast scientific conspiracy.
Or for that matter, think of anyone who cites “uncertainty” as a reason to do nothing — when it should be obvious that the risks of faster-than-expected climate change if we do too little dwarf the risks of doing too much if change is slower than expected.
But what’s driving this epidemic of bad faith? The answer, I’d argue, is that there are actually three groups involved — a sort of axis of climate evil.


First, and most obvious, there’s the fossil fuel industry — think the Koch brothers — which has an obvious financial stake in continuing to sell dirty energy. And the industry — following the same well-worn path industry groups used to create doubt about the dangers of tobacco, acid rain, the ozone hole, and more — has systematically showered money on think tanks and scientists willing to express skepticism about climate change. Many — perhaps even most — authors purporting to cast doubt on global warming turn out, on investigation, to have received financial support from the fossil fuel sector.
Still, the mercenary interests of fossil fuel companies aren’t the whole story here. There’s also ideology.

An influential part of the U.S. political spectrum — think the Wall Street Journal editorial page — is opposed to any and all forms of government economic regulation; it’s committed to Reagan’s doctrine that government is always the problem, never the solution.
Such people have always had a problem with pollution: When unregulated individual actions impose costs on others, it’s hard to see how you avoid supporting some form of government intervention. And climate change is the mother of all pollution issues.
Some conservatives are willing to face this reality and support market-friendly intervention to limit greenhouse gas emissions. But all too many prefer simply to deny the existence of the issue — if facts conflict with their ideology, they deny the facts.
Finally, there are a few public intellectuals — less important than the plutocrats and ideologues, but if you ask me even more shameful — who adopt a pose of climate skepticism out of sheer ego. In effect, they say: “Look at me! I’m smart! I’m contrarian! I’ll show you how clever I am by denying the scientific consensus!” And for the sake of this posturing, they’re willing to nudge us further down the road to catastrophe.
Which brings me back to the current political situation. Right now progressives are feeling better than they expected to a few months ago: Donald Trump and his frenemies in Congress are accomplishing a lot less than they hoped, and their opponents feared. But that doesn’t change the reality that the axis of climate evil is now firmly in control of U.S. policy, and the world may never recover.

Coral Reefs Fighting Climate Change #StopAdani #Auspol 

Mike Bloomberg’s New Frontier For Fighting Climate Change: Coral Reefs
Aug 12, 2017 @ 08:00 AM
50 Reefs

50 Reefs, a $2 million initiative funded by Michael Bloomberg, Microsoft cofounder Paul Allen and the Tiffany Co. Foundation, launched a platform on Thursday to take non-divers to the world’s biggest coral reefs — without getting them wet. 

Instead of a pleasant journey of the oceanic world, however, the initiative reveals a world through 360° images on Facebook where corals from the Great Barrier Reefs to Cook Islands die rapidly and the species that rely heavily on them disappear.


While coral reefs support 25% of all marine life worldwide, they are estimated to have a value of at least $1 trillion, generating $300 to 400 billion each year through food, tourism, fisheries, and medicines, according to the Word Wildlife Fund.

 50 Reefs says that 90% of coral reefs have been dying of overfishing, pollution and climate change, and will keep on dying in the next 30 years even with the Paris Climate Agreement in place. 

The initiative is now taking its fight to Washington, D.C. to push for immediate action, despite the fact that President Trump declared in June that the U.S. is pulling out of the Paris Climate Agreement.
“I realized most of the issues underwater are big communication challenges,” says Richard Vevers, whose nonprofit Ocean Agency is now spearheading the 50 Reefs initiative together with the University of Queensland.

 “The fact that people can’t see what’s going on underwater is a major issue,” he adds. 

Having documented the biggest global coral bleaching (dying off) event in history in the past three years, Vevers came up with an ambitious but what he calls a “manageable” project that would allow him and his team to identify reefs that are least vulnerable to climate change and then get them to reseed.

 “Corals are brilliant at essentially recovery once the environment they’re in is stabilized,” he says, “We are buying time so they can bounce back as naturally as possible.”
Upon hearing the concept of 50 Reefs, Bloomberg’s foundation reached out to Vevers in late 2016, and he showed the organization footage from his award-winning Netflix documentary, Chasing Coral, which debuted on the streaming service on July 14.

 In a time lapse video, coral reefs faded from florescent pink to white, and then to dark brown. “Their flesh is becoming clear, and you’re seeing their skeleton,” Vevers describes. Bloomberg, who is the UN Secretary-General’s Special Envoy for Cities and Climate Change, is one of the largest ocean donors and donated $53 million in 2014 to address overfishing, a catalyzer of coral bleaching.
Climate change hits the oceans harder than anywhere else and coral reefs are the “frontline of climate change,” according to Vevers. “Ninety three percent of the heat goes into the ocean,” the activist says: The Great Barrier Reef lost nearly half its corals in 2016 and 2017. Yet, he sees this environmental catastrophe as an opportunity for humanity to bounce back as well. “We’ve always portrayed climate change and climate action as something negative,” he says, “That’s the wrong way of communicating it. It’s about the business opportunities and it’s about improving lives.”

The planet’s worse case climate scenario. #StopAdani #Auspol 

The planet’s worst-case climate scenario: ‘If not hell then a place with a similar temperature’
Aug 12, 2017, 2:53 AM

If we don’t cut greenhouse gas emissions, we’ll see more deadly heat waves, acidic oceans, and rising seas.


At this point, the planet will warm no matter what — but we can still prevent it from getting too bad.

Environmentalist and author Bill McKibben told Business Insider that without intervention, the world would be: “If not hell, then a place with a similar temperature.”

The world is almost certainly going to warm past what’s frequently considered a critical tipping point.
A recent study pointed out that we have just a 5% chance of keeping the planet from warming more than 2 degrees Celsius, the upper limit the Paris Agreement was designed to avoid. Beyond that threshold, many researchers say the effects of climate change — like rising sea levels, ocean acidification, and intense storms — will become significantly more concerning.

But how bad could it really get? What would the planet look like if we don’t cut emissions and instead keep burning fossil fuels at the rate we are now?
Business Insider recently asked author and environmentalist Bill McKibben that question, and his description of what Earth would look like was sobering.
“If not hell, then a place with a similar temperature,” he said. “We have in the Earth’s geological record some sense of what happens when you run carbon levels up to the levels we’re running them now — it gets a lot hotter.”
Extreme as that might sound, there’s significant evidence that we’re feeling the effects of climate change already. Unchecked, the planet will get far hotter by 2100 — a time that many children alive today will see.


“Huge swaths of the world will be living in places that by the end of the century will have heat waves so deep that people won’t be able to deal with them, you have sea level rising dramatically, to the point that most of the world’s cities are drowning, the ocean turning into a hot, sour, breathless soup as it acidifies and warms,” McKibben said.
The evidence for how bad it could get
None of that is exaggeration. A recent study in the journal Nature Climate Change found that 30% of the world is already exposed to heat intense enough to kill people for 20 or more days each year. That temperature is defined using a heat index that takes into account temperature and humidity; above 104 degrees Farenheit (40 degrees C ), organs swell and cells start to break down.
Heat waves are the deadliest weather events most years , more so than hurricanes or tornadoes. In 2010, more than 10,000 people did in a Moscow heat wave. In 2003, some estimates say a European summer heat wave killed up to 70,000.
Even if we drastically cut emissions by 2100, the world will continue to warm due to the greenhouse gases that have already been emitted. That would cause the percentage of the world exposed to deadly heat for 20 or more days to rise to 48%. Under a scenario with zero emissions reductions from today, researchers estimate that 74% of the world will be exposed to deadly heat by the end of the century.
Our oceans are at risk, too. A draft of an upcoming US government report on climate change projects that even if emissions are cut to hit zero by 2080, we’ll still see between one and four feet of sea level rise by 2100. Without the cuts, it suggests that an eight-foot rise can’t be ruled out. That report also suggests that oceans are becoming more acidic faster than they have at any point in the last 66 million years. Increased acidity can devastate marine life and coral reefs, which cover less than 2% of the ocean floor but are relied upon by about 25% of marine species — including many fish that are key food sources for humans.
The key takeaway here is not that the world is doomed, however. It’s that if we don’t dramatically cut emissions soon, we’ll put the planet on course to be a much less pleasant place.
In some ways, progress towards emissions reductions is already underway. Market trends are increasing use of renewable energy sources, political movements are pushing leaders to enact new types of policies, and legal challenges to government inaction on climate are popping up around the world. The question is whether we’ll act fast enough to stave off the most dire consequences of greenhouse gas emissions.
“In order to catch up with the physics of climate change, we have to go at an exponential rate,” McKibben said. “It’s not as if this was a static problem. If we don’t get to it very soon, we’ll never get to it.”

Climate change denial looks a lot like psychosis #auspol #StopAdani 

New studies and new catastrophes give climate change deniers a lot to deny.

In this July 22, 2017, photo, Canadian Coast Guard Capt. Victor Gronmyr looks out over the ice covering the Victoria Strait as the Finnish icebreaker MSV Nordica traverses the Northwest Passage through the Canadian Arctic Archipelago.

 Nordica has set a new record for the earliest transit of the fabled Northwest Passage. 

The once-forbidding route through the Arctic, linking the Pacific and the Atlantic oceans, has been opening up sooner and for a longer period each summer due to climate change.

David Goldman AP

August 10, 2017 7:01 PM
Denial begins to look like psychosis.
Just in the past week, a cascade of new findings and climate anomalies have added to the scientific consensus that we’re cooked. Miami in particular.
We’re seeing wildfires in Greenland, for heaven’s sake. 

Famously soggy Seattle has just gone through a record 54 consecutive days (and counting) without rain.
On Thursday, Arctic explorer Pen Hadow left Nome, Alaska, in a 50-foot sailboat intent on something unfathomable before the onset of global warming.

 He and his crew intend to sail through the melting ice pack to the very North Pole. “If we can produce a visual image of a sail boat at 90 degrees north I think that could become an iconic image of the challenge that the twenty-first century faces,” Hadow wrote in his blog.
That image would nicely illustrate the National Climate Assessment draft report publicized this week by the New York Times.

 “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” noted the assessment, based on input by scientists from 13 different federal agencies.


Scientists involved in the report were worried that Donald Trump, our climate-denier-in-chief (a Chinese hoax, he called global warming) would suppress the final report, which concluded that it was “extremely likely” that human activity accounted for more than half of the rising global temperatures since 1951.
“Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans.”
Draft report of the National Climate Assessment
The assessment makes for particularly gloomy reading in South Florida, where rising waters already plague our ritziest zip codes. “It is very likely that the accelerated rate of Arctic warming will have a significant consequence for the United States due to accelerating land and sea ice melting that is driving changes in the ocean including sea level rise threatening our coastal communities.”
Yeah, that’s us.
That ought to convince even the most obstinate politicians that unless something is done about greenhouse emissions, we’re in deep, deep (as in encroaching sea waters) trouble.
But there was more.

On Wednesday, researchers from the University of Florida published findings in the journal Geophysical Research Letters that sea levels along the southeast Atlantic coast, south of Cape Hatteras down to South Florida, are rising six times faster than the global averages. So if sea level rise is bad elsewhere, it’s going to be hell in Miami.
That was published the very same day that Swiss Re, a Switzerland-based reinsurance company, released an analysis that climate change and rising seas, in league with population growth and coastal development, has rendered Miami vulnerable to unimaginable losses if a Hurricane Andrew-sized storm strikes the city. “Losses in this case are estimated to be $100-$300 billion, making it the costliest natural disaster ever seen in the U.S.,” Swiss Re reported. Only $60-180 billion of Miami’s property losses would be covered by the private insurance market, “leaving a huge shortfall in funding to rebuild.”
Swiss Re added that “risk mitigation and climate adaptation are keys to strengthening community resilience.”
That ought to be obvious. Except we have a president in Washington and a governor and a speaker of the House in Tallahassee who pretend global warming is some kind of liberal invention. Two years ago, employees of the Florida Department of Environmental Protection claimed they had been barred from using the terms “climate change” or “global warming” in emails, reports or official communications. That doesn’t sound like an administration ready to confront Florida’s coming climate crisis.
Meanwhile, a dozen of Florida’s U.S. representatives and one of its U.S. senators (Marco Rubio) are essentially climate change deniers.
They’ve somehow held onto their “it ain’t happening” beliefs even during what the National Oceanic and Atmospheric Administration has described as the second-warmest year in the contiguous United States (so far) in 123 years of record keeping. In case you didn’t notice, July was the hottest month ever in Miami, according to Climate Central.
While 2016 was the second warmest year on record (after 2012) in the U.S., it was the hottest ever for the planet. NOAA reports that 16 of the 17 warmest years on record, worldwide, have occurred since 2001.


Yet our pols pretend otherwise. (They ignore a report on the effects of climate change in Architectural Digest that said rising seas have made South Florida “the worst metropolitan area in the country in regards to storm surge risk, with an estimated 780,000 homes potentially affected.”)
They just keep denying. Even during a week when a Russian tanker, without an ice breaker escort, was able to traverse the Arctic with a load of liquid natural case. In a week when the Asian Development Bank warned that, “unabated climate change” would lead to “disastrous climate impacts for the people of Asia and the Pacific.” Which echoed a study published this week in the journal Science Advances warning that “Climate change, without mitigation, presents a serious and unique risk in South Asia, a region inhabited by about one-fifth of the global human population, due to an unprecedented combination of severe natural hazard and acute vulnerability.” The journal warned that “the most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins.”
It was a week when geologists warned that “all glaciers in Iceland are retreating at an unprecedented pace.” A week when a study published in the Lancet Planetary Health declared, “Climate change is one of the biggest global threats to human health of the 21st century.”
So much dire news in single week. Not that our steadfastly oblivious leaders in Washington and Tallahassee were deterred by melting glaciers or droughts or wildfires or record temperatures or rising seas or disappearing polar ice or threats to human health. Deniers just keep on denying.

Wake up call: We need to act now on #ClimateChange #auspol 

Wake-Up Call: Asia-Pacific Needs to Act Now on Climate Change
Hans Joachim SchellnhuberAugust 11, 2017

“The Asian countries hold Earth’s future in their hands. 

If they choose to protect themselves against dangerous climate change, they will help to save the entire planet.” 

That’s how Hans Joachim Schellnhuber, a leading climate change researcher and founding director of the Potsdam Institute for Climate Impact Research, sees it.


He made the comments recently during the launch of a new report from the Asian Development Bank and its research institute. 

The report, A Region at Risk: The Human Dimensions of Climate Change in Asia and the Pacific, presents the latest research on the dire consequences of climate change in Asia and the Pacific under a business-as-usual scenario.


Schellnhuber spoke with ADB about the climate-related challenges facing Asia and the Pacific.
Asian Development Bank: What are the main impacts of climate change foreseen under the business-as-usual scenario?
Hans Joachim Schellnhuber: First of all, one needs to get a sense of what it really means. 

We talk about 4 to 6 degrees of warming—planetary warming, so the global average—by 2100 if we do business-as-usual. 


Think of the global mean temperature as your body temperature. 

If you have 2 degrees warming in your body you have fever. 

Six degrees warming means you are dead. 

That’s the metaphor to use for the planet. 

That means with 4 to 6 degrees warming our world would completely change. The world as we know it would disappear.
Maybe it’s most clearly understood in terms of sea level rise. 

One degree warming means at least 3 to 4 meters’ sea level rise; 2 degrees warming would mean 7 or 8 meters’ rise. 

This would simply mean that many of the low-lying island states would disappear. 

Their home would be destroyed. We need to do everything to avoid that.

ADB: How will climate change impact individuals?
Schellnhuber: Just a week ago in Asia you had temperatures of 54 degrees centigrade in Pakistan and in Iran. 

We can calculate that with 5 to 6 degrees global warming you would create uninhabitable zones on this planet. 

There would be regions, in particular in Asia, where you could not survive in the open without air conditioning physiologically. 

Temperatures would hit 60 degrees and it simply would mean that you would have no-go areas.

 Now think of slums, where people do not have air conditioning now. 

There will be places where you cannot work and you cannot survive.


So it is really about, “Can you survive under climate change?” And the answer is, “No”— at least in certain regions in Asia.
ADB: The report also anticipates significant climate-related migration.
Schellnhuber: What we are really worried about is migration and conflict. In the end, all these knock-on effects will heavily impact on national security and international migration. It might mean that hundreds of millions of people will be displaced because of global warming; and you have to accommodate them.
We in Europe just had this experience. In Germany in particular, we have taken up a million refugees. Believe me, this is very hard to digest. Now, we are talking about a million being absorbed by one of the richest countries in the world. Think of hundreds of millions of people being absorbed by poor people, by poorer countries.
If people are displaced in Bangladesh they will generally go to West Bengal in India, for example. If Tuvalu gets inundated, people will hop to the next island. They will not buy a business class ticket and go to Los Angeles.
Digesting, absorbing major migration waves is a challenge I think most of the current nations will not be able to meet. So let’s avoid it.
ADB: What are the implications for business and the regional economy?
Schellnhuber: We often make this joke that the first law of capitalism is, “Don’t kill your customers!” If you kill your customers, you cannot do business. But in a more sober way you can look at the various sectors, agriculture, fisheries, and so on.
For fisheries, climate change comes with ocean acidification. Half of the CO2that we put into the air by burning fossil fuels is absorbed by the oceans. If this isn’t stopped, under a business-as-usual scenario oceans will get so acidic that the coral reefs will dissolve virtually.
Now one-third of marine productivity—including the top predators, fish—is created in the corals. So, the marine business will just be destroyed. The same is true for tourism: If you have no corals you will have no people going to the coral reefs. The Great Barrier Reef, for example, is at stake as well as the Coral Triangle.
We did a study, and this is in the report, of how global supply chains will be disrupted or even interrupted by extreme events. When there were the big floods in Thailand, for example, a sort of wave was created all over the planet. First the computer industry in Japan was hit, and ultimately in the U.S. and so on. You have knock-on effects, cascades of impacts. To put it in one sentence: Climate change is really bad for business.
ADB: How should governments, business, and citizens respond?
Schellnhuber: First, you have to recognize the problem.

 Our report is a wake-up call. 

If you read it you get scared.

 But you need to be scared because the future would be very bleak if we just do business-as-usual. 

Once you know there is a big problem, then you have to assess how the various nations and regions will be affected.

Even 2 degrees warming will deliver a completely new world. 

You have to find out what are you going to do in Vietnam, what are you going to do in South India, in Kazakhstan, in Uzbekistan. 

What needs to happen in Tuvalu and Vanuatu?
First, try to provide the evidence and based on that you can do good projects. But you have to do it within a strategic framework. I would urge ADB to first come up with a differentiated assessment of the situation and then go in and implement best practice and act on the best proposals.
ADB: Do you see any silver lining?
Schellnhuber: People feel there is a trade-off between development and climate protection, but that’s not true. As our report makes clear, if you do not stabilize the climate you will actually destroy the good prospects for development. And if you take climate action in a clever way you will create new opportunities for doing business.
I will give you just one example: The modern society was based on the use of fossil fuels. The industrial revolution started 200 years ago in England and Scotland. 

This was based on using, in a clever way, coal and later gas and oil. But now this model has come to an end.


This may just push us into adopting a new model for growth. Solar energy is abundant in Asia, for example. It is free. The sun is shining without any charge. I think the climate issue is giving us the right push to go into a new industrial model and that will be built on renewables, recycling, a circular economy, and the better use of resources.
In a way, it’s an eye-opener. Because we almost destroyed our civilization through the externality of climate change, we wake up and say, “Oh, there is an even better model of doing sustainable business.”
I think we will have another industrial revolution, even a bigger one. And it will be the most important modernization project in the 21st century. The opportunity is there. Let’s do new business, better business involving more people, and as a nice side effect we will save the planet.

Bleak world if the Great Barrier Reef dies. #StopAdani #auspol #qldpol 

Scientist Dr Charlie Veron’s warning to Gold Coasters of a bleak world if the Great Barrier Reef dies

A RENOWNED scientist has painted a bleak picture of the impact on the Gold Coast if the Great Barrier Reef dies, warning of a worldwide environmental disaster that will hurt even more if rising carbon dioxide levels keep cooking the planet.
Dr Charlie Veron has urged young Gold Coasters to build multiple skills for a chaotic world, saying important fields like medicine and agriculture will be vital as carbon dioxide levels increase because of the burning of fossil fuels, particularly coal.
Even if nations stopped production of carbon dioxide, the oceans would keep heating for another 20 years, leading to a vicious pendulum ride between cyclonic storms and floods, and severe drought and bushfires.

“Half of all coral colonies on the Great Barrier Reef died over the past two years due to coral bleaching,’’ Dr Veron said.
“It’s going to be a horrible world. Young people now are going to curse the present generation for what we’ve done. We’ll have left them a planet in dire straits.’’
Known as the Godfather of Coral, Dr Veron has been hailed by the likes of high-profile British naturalist David Attenborough for his career that led to him being appointed chief scientist of the Australian Institute of Marine Science and to recognition as a wideranging specialist in corals and reefs.

Dr Charlie Veron was the first full-time researcher on the Great Barrier Reef and has described more than a quarter of the world’s coral species.

With several books to his name including his memoir, A Life Underwater, Dr Veron was a prominent speaker at the Byron Writers Festival at the weekend.
“The Australian public is asleep. They seem to be unaware of what’s going on,’’ he told the Gold Coast Bulletin outside the festival.
Rising levels of the otherwise rare gas carbon dioxide were increasing ocean temperatures, which were causing bleaching and killing coral reefs, putting the entire marine environment in peril.
“Australia is now the biggest coal exporter in the world,’’ he said.
“Australians are fuelling this as fast as they can through the mining of coal, which is the worst driver of this.’’
Dr Veron, who has been an outspoken critic of the proposed Adani coal mine in Central Queensland, feared the Great Barrier Reef could be gone within 15 years.

“If the Great Barrier Reef dies then you can be sure most coral reefs in the world would have died and the oceans will be in a state of ecological collapse. Nowhere is going to be exempt,’’ he said.
“We will see fishing industries collapse, for starters.
“Between a quarter and a third of all marine species have part of their life cycle in a coral reef. Taking away the reefs precipitates ecological collapse of the oceans. It’s happened twice in the past due to volcanoes releasing carbon dioxide and lava flows, but that was nothing like the amount of carbon dioxide being released now.’’
One of those mass extinctions, at the end of the Mesozoic era 65 million years ago, brought an end to the dinosaurs. The other was at the end of the Palaeozoic era about 200 million years ago, which wiped out corals.
“A lot of marine species here (in Gold Coast and Byron Bay waters) have come from the Great Barrier Reef,’’ Dr Veron said.
“The corals here have all come from the barrier reef as have all the tropical marine species. They come down the East Australia Current and colonise here. This applies to migratory fish species too.
“It’s all gloom and doom, I’m afraid.
“The science has been right.
“The sceptics now have no credibility. The deniers of climate change might as well deny Jumbo jets can fly. It’s no longer an issue of science or judgment. It’s happening.’’
Carbon dioxide was important in keeping the earth warm and keeping green plants going.
But concentrations had now reached 406 parts per million.
“But when you go over the limit it becomes a very dangerous gas,’’ he said. “It’s now reached that point.
“It’s doing this slowly. It’s like putting a jug of water on the stove. It takes a long time to equilibrate with the heat under it.
“The oceans are taking at least 20 years to equilibrate with current conditions. We have oceans that have warmed in response to carbon dioxide levels of the 1990s. (Even if carbon dioxide production stopped now) the oceans have got 20 years of warming ahead.’’

Climate Science Special Report. #Auspol #StopAdani

Executive Summary

Introduction

New observations and new research have increased our understanding of past, current, and
future climate change since the Third U.S. National Climate Assessment (NCA3) was
published in May 2014.

 This Climate Science Special Report (CSSR) is designed to capture
that new information and build on the existing body of science in order to summarize the
current state of knowledge and provide the scientific foundation for the Fourth National
Climate Assessment (NCA4).

Since NCA3, stronger evidence has emerged for continuing, rapid, human-caused warming of
the global atmosphere and ocean. 


This report concludes that “it is extremely likely that human
influence has been the dominant cause of the observed warming since the mid-20th century.

 For the warming over the last century, there is no convincing alternative explanation
supported by the extent of the observational evidence.”

The last few years have also seen record-breaking, climate-related weather extremes, the three
warmest years on record for the globe, and continued decline in arctic sea ice.

 These trends
are expected to continue in the future over climate (multidecadal) timescales. 


Significant
advances have also been made in our understanding of extreme weather events and how they
relate to increasing global temperatures and associated climate changes.

 Since 1980, the cost
of extreme events for the United States has exceeded $1.1 trillion, therefore better
understanding of the frequency and severity of these events in the context of a changing
climate is warranted.

Periodically taking stock of the current state of knowledge about climate change and putting
new weather extremes, changes in sea ice, increases in ocean temperatures, and ocean
acidification into context ensures that rigorous, scientifically-based information is available to
inform dialogue and decisions at every level. 


Most of this special report is intended for those
who have a technical background in climate science and to provide input to the authors of
NCA4.

 In this Executive Summary, green boxes present highlights of the main report. 

These
are followed by related points and selected figures providing more scientific details. 

The
summary material on each topic presents the most salient points of chapter findings and
therefore represents only a subset of the report’s content. 

For more details, the reader is
referred to the individual chapters. 

This report discusses climate trends and findings at several
scales: global, nationwide for the United States, and for ten specific U.S. regions (shown in
Figure 1 in the Guide to the Report)

A statement of scientific confidence also follows each
point in the Executive Summary. 

The confidence scale is described in the Guide to the Report.
 

At the end of the Executive Summary and in Chapter 1: Our Globally Changing Climate, there is also a summary box highlighting the most notable advances and topics since NCA3 and since the 2013 Intergovernmental Panel on Climate Change (IPCC) report.
