Valley Voice: The science that reveals climate change is sound

By Dwight Fine 

In his April 10 Valley Voice, “Another opinion on climate science,” Larry Wilhelmsen expresses skepticism over climate change and bases that skepticism, in part, on a petition signed by “31,000 people with various science-related degrees,” and on two publications by atmospheric scientists. 

This illustrates the denialist techniques of “fake experts” and “magnified minority.”
The “petition signed by 31,000 scientists” has long since been discredited. 

The petition was sent out by the Oregon Institute of Science and Medicine, a small group calling itself a research organization. 

Anyone with a bachelors degree or higher in a science-related field was invited to sign. 

Examination of the signatures showed that only about 0.1% of the signers had ever had any involvement with climate science research.

I do not feel that my own Ph.D. in chemistry qualifies me to speak with authority on climatology; instead, I look for the consensus of scientists who have actually done research in the field and have published their results in peer-reviewed journals.

Studies of publications of climatologists have been carried out at Queensland University, the University of Chicago and Princeton University. These studies examined some 12,000 publications.

 The average for the studies showed that 97 percent of climate scientists supported the hypothesis that global warming is real and mainly induced by human activity.

Furthermore, some 30 major scientific societies such as the American Chemical, Physical and Geological Societies have now endorsed this hypothesis, as have the national science academies of 80 countries. Are we to believe that all of these scientists, societies and academies are engaged in a gigantic conspiracy to perpetrate a hoax?
Wilhelmsen states that climate has changed forever and that advocates of human-induced climate change have stopped calling it global warming because warming was stopping. Stopping? 2016 was the warmest year on record, according to data reported by NASA and NOAA, and 15 of the 16 warmest years on record have occurred since 2001. Yes, the climate has always changed, but it has never changed at such an abrupt rate as we are observing now. The term ”climate change” came into use so as to be more inclusive of events other than increased surface temperatures.
Such events include:

1) increased severity of blizzards, tornadoes, flooding and wildfires;

2) sea level rise;

3) warming of oceans and increasing acidification of ocean waters due to increased concentrations of carbonic acid; this has led to extensive destruction of coral reefs;

4) declining Greenland and Antarctic ice sheets;

5) declining Arctic sea ice – we now have cruise ships sailing the once impenetrable Northwest Passage;

6) retreating of glaciers in the Himalayas, Andes, Alps, Rockies and Alaska.


As to the “pleasures” we owe to fossil fuels the Wilhelmsen referenced, such pleasures are becoming limited. Reserves of coal and oil are finite and non-renewable, and these fuels become increasingly difficult, expensive and hazardous to extract as reserves are depleted. Landscapes are littered with abandoned strip mines and oilfields, often laden with toxic chemicals. Renewable energy would seem to offer far greater potential in the way of jobs and development.
For readers confused by denialist rhetoric in regard to climate change, I recommend the websites climate.nasa.gov and skeptical science.com.

The Solution Is Global Equality #auspol 

The Solution To Extremism Is Global Equality

By Stephan Said
The solution to extremism surrounding us today is global equality. 

To stop the religious, ethnic, and political extremism killing people from Colorado Springs, to Baghdad, San Bernardino and Bamako — to stop the environmental extremism that is burning up our planet — we must stop global inequality, imperialism and greed.
The entire human race is faced with a great ideological dilemma. 

We cannot separate ISIL, planned-parenthood shooters, or global warming. From extreme violence to extreme weather, extremism is rising like the oceans around us because the moral bankruptcy of our troubled world is pushing people and our planet to extremes — suicide bombings and natural disasters.
What we are witnessing is the failure of all existing ideologies and socio-economic systems on earth to have created a sustainable society in which we live in peace. 

We are all responsible for this failure. 

We have destroyed the cradle of civilization, killed millions and created the biggest refugee crisis in generations, for the control of the oil that is making the ice caps melt. 

Anyone who is angry is justified.
However mistaken violent extremism is as a response, it is offering would-be recruits a way to do something to change this unjust world not tomorrow, but today. 

If we want to win this war, we can only do so by lifting a higher, universal ideology by which humankind can live in peace with each other and with nature.
This ideological war is as old as human civilization, and so is the answer. 

No civilization is sustainable unless all of its members are treated as equals, and unless that civilization lives in harmony with nature.

Writers such as Arundhati Roy, Thomas Piketty, Nicolas Henin and Naomi Klein have drawn these connections in recent articles. But, the fact is, humankind has known the deal for thousands of years. We don’t have time to waste restating the obvious. It is urgent. The human race is facing its long-anticipated day of reckoning with its own failure to create a just world.
We have to pick up the torch where Martin Luther King, Jr. left it. 

The cause of global warming and of rising violence between us on earth is due to social and economic inequality. The answer is to organize a mass, global non-violent movement for equality.
We must get beyond the institutional language of a “more equitable world.” Equality is a universal way of being that must become a new socio-economic order that commits to and promises the idea that all people everywhere live equally with each other and nature.
We must demand a united global society across borders. 

We must demand every human being is cared for, fed, housed, educated, given equal voice and dignity, everywhere. We must demand a world in which humankind restores everything we take from nature. 

We must demand that we leave our world better than we found it, not selfishly for our children, but out of deference to the laws of nature itself.


First and foremost we must demand this of ourselves, as it will take unbelievable tolerance, acceptance and forgiveness to do so. 

Then, we must demand this of our governments, religions, political parties, and economic forces, and we must be willing to go into the streets non-violently demanding this global shift.
When we accept that we are all equals with each other and nature, we will not be able to be manipulated and separated from each other by false notions such as ethnicity, religiosity, nationality, or superiority of any kind. This is the only way to peace.
Peace is not impossible. 

I know, because I am the impossible.

 My aunt and cousins from Mosul, Iraq are now refugees because ISIL occupied their next-door neighbors’ house. 

The U.S. sent fighter jets and bombed it to the ground. They had to abandon everything and are somewhere across the border in Turkey.
My father’s Iraqi, Muslim family are refugees for the same reason that my mother’s Austrian, part-Catholic part-Jewish family were refugees and imprisoned or died in Dachau, Mauthausen and Auschwitz.

 Including my cousins’ children today, 6 consecutive generations of my family have been refugees as Catholics, Jews, and Muslims, because of inequality.
With all sides of the prevailing conflict consuming our world today within me, I’ve spent my life studying the single cause of war and hatred simply to be at peace with and construct my own identity. Inequality is the single cause of the chaos enveloping our world.
The majority of us on earth, in every country, in every religion, of every ethnicity knows what we have to do. 

Many people, parents, teachers, governments, and organizations are already working on the systemic shift necessary for the survival of humankind and our planet.

 I have given my entire career and written countless songs to build such a movement. But now, we must come together and turn our demand into action.
We are faced with the task of creating a new global socio-economic model sufficient to create sustainable peace on earth. A mass non-violent movement demanding that all people live equally with each other, loving each other, caring for our planet, is the only solution. 

We have to start today.

Climate Change is Rapidly Accelerating! #auspol #Qldpol 

Climate change is rapidly accelerating. 

By  Paul Dawson

Data shows 16 of the world’s 17 hottest years have occurred since 2000. 


Carbon dioxide concentrations have accelerated to the highest levels in human history. 

There is no natural explanation for this. 

Scientists and models may have been too conservative in the past. 

The frequency and intensity of extreme weather events, heat waves, droughts, flooding and wildfires are all accelerating. So are health effects from climate change, such as heat stress, air pollution and infectious diseases. Oceans are warming about 13 percent faster than previously thought and the destruction of coral reefs is happening at a rate that scientists didn’t expect for another 30 years.


The Arctic is warming at two to four times the rate as the rest of the planet.

 Sea ice is melting from above and below and is very shallow. Greenland ice sheets are also quickly melting and are increasing global sea levels. As the Arctic warms and loses its ice, it absorbs more solar radiation and warming accelerates. This produces more water vapor, a greenhouse gas. In addition, the Arctic permafrost melts and some of the abundant greenhouse gases (GHG) of methane and carbon dioxide from organic materials in the frozen soil are released into the atmosphere. In time, humanity’s release of GHG may be small in comparison to the natural release mechanisms of the GHG from the ocean, wetlands, soils, and permafrost of the Arctic. But this tipping point has not been reached yet.
 

Many Americans seem to lack a sense of urgency in dealing with climate change. 

A few years ago, mankind used chlorofluorocarbons as refrigerants and in aerosol dispensers and these chemicals reacted with ozone to create a hole in the ozone layer of the atmosphere. The ozone layer absorbs harmful solar ultraviolet radiation. Thankfully, the countries respected scientific findings and agreed to stop using the damaging chemicals. Now, ozone is filling in the opening and the ozone crisis has ended.
Fortunately, renewable energy can now compete economically with fossil fuel energy, especially if energy subsidies were removed. The International Monetary Fund (IMF) estimates that global energy subsidies, including the social and environmental costs associated with heavily subsidized fossil fuels, are costing the world’s governments upward of $5 trillion annually. This figure includes over $700 billion in subsidies to U.S. fossil fuel companies. This is equivalent to every American giving fossil fuel corporations $2,180 annually in the form of taxes. This is absurd and shocking. The IMF said that ending subsidies for fossil fuels would cut global carbon emissions by 20 percent.
Let’s end energy subsidies. 

Let’s reverse carbon and methane emissions.

 Let’s support the Paris Agreement and make climate change a high priority for us and for our elected officials. 

Please join the People’s Climate March on Saturday, April 29.
Paul Dawson is an emeritus professor of engineering at Boise State University, specializing in the thermal sciences, atmospheric science and renewable energy.

Deadly Threat to Coral #climatechange #auspol

Climate change remains the biggest threat to coral reefs around the world, with rising sea surface temperatures driving widespread bleaching events, according to the Climate Council’s latest report.
The report ‘Climate Change: A Deadly Threat to Coral Reefs’, shows worsening bleaching events are also placing tourism and global economies at risk, with the loss of coral reefs potentially costing an astounding $1 trillion.

KEY FINDINGS
1. The Great Barrier Reef is experiencing severe bleaching in 2017, following the worst bleaching event on record in 2016.

Last year the Great Barrier Reef experienced its worst bleaching event ever. The pristine reefs in the north (Port Douglas to Papua New Guinea) were the most badly affected, with mortality of two-thirds of coral in this region.

While the El Niño has waned, bleaching on the Great Barrier Reef has continued, fueled by climate change.

Severe bleaching has already been observed in offshore reefs from north of Ingham to near Cairns. In 2017 more bleaching is being observed in the central section of the GBR, which was spared last year.

Reefs bleached in both 2016 and 2017 have had no opportunity to recover and so high mortality rates can be expected.


2. Climate change is threatening our reefs and putting their future health at extreme risk.
Rising sea surface temperatures, driven by climate change, are increasing the frequency and severity of mass coral bleaching events and reducing the opportunities for corals to recover.

The longest global coral bleaching event on record, ongoing since 2014, has led to widespread bleaching and mortality of reefs as pools of unusually warm water move around the globe. 

It was virtually impossible for the extreme ocean temperatures that led to coral bleaching along the Great Barrier Reef in 2016 to have occurred without climate change.

3. Coral reefs are a huge economic asset, providing jobs and incomes to local communities.

Loss of coral reefs potentially puts an astounding $1 trillion at risk globally.

The World Heritage-listed Great Barrier Reef is a national economic asset worth $7 billion annually, supporting the livelihoods of 69,000 Australians employed in sectors such as tourism.

If severe bleaching continues, regions adjacent to the Great Barrier Reef risk losing more than 1 million visitors annually – equivalent to at least $1 billion in tourism spending and 10,000 jobs.

Over the next two to three decades, bleaching events are likely to become even more frequent and severe in Australia, with catastrophic impacts on reef health and the economy.


4. We must rapidly reduce greenhouse gas emissions now to protect our reefs.

While carbon emissions flat-lined last year in China and declined in the United States and elsewhere, Australia’s net emissions continue to rise, increasing by 0.8% in 2016.

Over the next two to three decades, bleaching events are likely to become even more frequent and severe in Australia, with catastrophic impacts on reef health and the economy.

In the long term, protecting our coral reefs requires the rapid phasing out of fossil fuels globally, and the uptake of cheap, clean and efficient renewable energy and energy storage technologies. Australia must play its part.

The commissioning of new coal mines such as that planned for the Galilee Basin, and the pursuit of polluting and expensive “clean coal” projects and new gas plants, is completely at odds with protecting the Great Barrier Reef and other reefs globally.

Melting Permafrost Threatens To Unleash Dangerous Climate Feedback #auspol

Earth’s melting permafrost threatens to unleash a dangerous climate feedback loopNew permafrost study underscores the critical importance of ambitious climate targets, like the Paris agreement.

By Dr Joe Romm

In this so-called “drunken forest,” in Alaska, the trees tilt because the once-frozen ground (permafrost) is thawing. CREDIT: NSIDC.

Global warming will defrost much more permafrost than we thought, a new study finds. Every 1°C (1.8°F) of additional warming would thaw one-quarter of the earth’s frozen tundra area — releasing staggering amounts of heat-trapping greenhouse gases (GHGs).

Those GHGs would in turn warm the planet more, melting more permafrost, releasing more GHGs, and so on. This is perhaps the most dangerous amplifying carbon-cycle feedback humanity faces — considering permafrost contains twice as much carbon as the atmosphere does today.

That’s why it’s so vital the U.S. adheres to its commitments in the 2015 Paris climate agreement — a landmark accord in which the world unanimously committed to keep ratcheting down carbon pollution to ensure total warming stays “well below 2°C [3.6°F] above pre-industrial levels.” And that’s why President Donald Trump’s efforts to undermine the deal are so dangerous, since they may put the permafrost — and hence our livable climate — across a point of no return.

Trump’s executive order puts the world on the road to climate catastrophe
It’s so egregious, it no longer really matters if he doesn’t formally opt out of the Paris climate deal.
If we could limit total warming to the 1.5°C target identified in the Paris deal, that would save 800,000 square miles of permafrost compared to 2°C warming. But if the Trump administration succeeds in thwarting Paris, then we may lose more than half of the permafrost.

By way of background, the permafrost, or tundra, is soil that stays below freezing (0°C or 32°F) for at least two years. Normally, plants capture CO2 from the air during photosynthesis and slowly release that carbon back into the atmosphere after they die. But the Arctic acts like a very large carbon freezer — and the decomposition rate is very low. Or, rather, it was. We are leaving the freezer door wide open. The tundra is being transformed from a long-term carbon locker to a short-term carbon unlocker.

Significantly, while most of the carbon in a defrosting permafrost would probably be released as CO2, some would be released as methane, which which traps 86 times as much heat as CO2 over a 20-year period.

Yet one study found that the feedback from just the CO2 released by the thawing permafrost alone could add 1.5°F to total global warming by 2100, if we don’t sharply curtail carbon pollution as soon as possible. Worse, none of the models for the recent Fifth Assessment of the climate by the world’s top scientists incorporate loss of the permafrost in their warming assessments.

The bottom line of this new study was well summed up in the headline of its news release: “Huge permafrost thaw can be limited by ambitious climate targets.” And that means huge permafrost thaw can be caused by undermining those targets.

CO2 the ever increasing driver of global warming! #auspol #qldpol 

The primary driver of global warming, disruptive climate changes and ocean acidification is the ever-increasing amount of carbon dioxide in our atmosphere.

By Barry Saxifrage

Despite decades of global efforts towards climate policies, clean energy and efficiency, CO2 levels continue to rise and are actually accelerating upwards.

 For those of us hoping for signs of climate progress, this most critical and basic climate data is bitter news indeed.

 It shows humanity racing ever more rapidly into a full-blown crisis for both our climate and our oceans.
That’s the story told by the newest CO2 data released by the United States National Oceanic and Atmospheric Administration (NOAA). Let’s take a look….
Even the increases are increasing

Even the increases are increasing

Annual CO2 increase in atmosphere

My first chart, above, shows NOAA’s CO2 data thru 2016.
Each vertical bar shows how much the level of CO2 in the atmosphere increased that year. You can see at a glance how the annual changes keep getting larger.
Indeed, the last two years (dark orange) saw CO2 rise by three parts-per-million (3 ppm) for the first time ever recorded.
And the relentless upwards march of CO2 is even more clear in the ten-year averages.
Annual atmospheric CO2 increases. Ten-year averages.

My second chart shows these ten-year average increases as yellow columns. Up, up, up.
“Unprecedented”
NOAA’s press release highlighted the “unprecedented” CO2 rise in last two years.
The scientists also pointed out that 2016 “was a record fifth consecutive year that carbon dioxide (CO2) rose by 2 ppm or greater.” Those last five years also broke a new record by exceeding +2.5 ppm per year for the first time.
I’ve included both the new five-year record and the new two-year record as black bars on the chart. All told, we’ve managed to pull off the triple crown of climate failure. The last ten years, five years and two years have all smashed records for CO2 increases.
If humanity is making climate progress, someone forgot to tell the atmosphere about it.
I thought we were making progress on CO2, what’s going on?
Recently the climate press has been buzzing about a hopeful CO2 report from the International Energy Agency (IEA). The IEA estimates that fossil fuel CO2 didn’t increase in either 2015 or 2016. Even better, they point out, this is the first time that has happened while the global economy expanded. I was curious how to reconcile this plateau in fossil fuel CO2 with the continued acceleration of atmospheric CO2. Here’s what I found:
Fossil fuel CO2 might be increasing.

 The IEA numbers might be wrong. 

They rely on nations to accurately report their fossil fuel use.

 Not all of them do, especially when it comes to burning their own coal supplies. 

In fact, the lack of a system to accurately verify national CO2 claims was a key issue in the Paris Climate Accord discussions.

 The worry is that as nations face increasing pressure and scrutiny around their CO2, the incentives to cook the books will increase.

 Incorrect accounting of just one percent globally could switch the storyline from “hopeful plateau” to “continuing acceleration”. 

The IEA devotes two chapters of their “CO2 Emissions from Fuel Combustion” report to the various issues impacting data accuracy.

Humans might be increasing CO2 emissions from other sectors. 

Roughly a quarter of the CO2 released by humans comes from non-energy sources not covered in the EIA numbers. These include land use changes, agriculture, deforestation, fugitive emissions, industrial processes, solvents and waste.

 We could be increasing CO2 from these.

Climate change might be increasing CO2 emissions. 

Increases in wildfires, droughts, melting permafrost — as well as changes to plankton and oceans — can all cause sustained increases in CO2 emissions. And climate change is affecting all of these. Perhaps some of these changes are underway.

The oceans and biosphere might be absorbing less of our CO2. Much of the CO2 humans release gets taken up by the oceans (ocean acidification) and the biosphere (increased plant growth). Some climate models predict these “CO2 sinks” will lose their ability to keep up. If that is starting to happen, then dumping the same amount of CO2 into the atmosphere will result in increasing amounts staying there.

Unfortunately we don’t have good enough measurements to say what the mix of these factors is. However, what we can accurately measure is the CO2 level in our atmosphere. That’s the CO2 number we have to stop from rising because it is what drives global warming, climate changes and ocean acidification. Sadly, it’s also the CO2 number that shows no sign of slowing down yet.
Out burping the ice age
NOAA’s press release also provided some perspective on how historically extreme our atmosphere’s CO2 increases have been:
“… the rate of CO2 growth over the last decade is 100 to 200 times faster than what the Earth experienced during the transition from the last Ice Age. This is a real shock to the atmosphere.”
For context, during the last ice age all of Canada was buried beneath a massive northern ice cap. The ice was two miles thick over the Montreal region, and a mile thick over Vancouver. So much water was locked up in ice that global sea levels were 125 meters (410 feet) lower. We are talking a lot of ice and a radically different climate.
Recent research reveals that:
“… a giant ‘burp’ of carbon dioxide (CO2) from the North Pacific Ocean helped trigger the end of last ice age, around 17,000 years ago.”
Just how big of a CO2 ‘burp’ did it take to help heat the frigid global climate, eliminate the continent-spanning ice sheets and raise sea levels by hundreds of feet? Around 80 to 100 ppm — the same amount we’ve belched into our atmosphere just since 1960. We did it 100 times faster than that so-called “burp” and we are still accelerating the rate we pump it out.
I’ve added the ice-age-ending ‘burp’ rate as a red line on the chart above. Look for it way down at the bottom. Such incredible climate altering power from even small CO2 increases shows why we must reverse the buildup of CO2 in the atmosphere.
Adding it up: the rising level of CO2 in our atmosphere
So far we’ve only been looking at annual increases in the amount of carbon dioxide in the atmosphere. It’s an important metric to evaluate whether we’re making any progress against climate pollution. But what actually drives the greenhouse effect is the total amount that has accumulated in our atmosphere over time. So let’s take a look at that.
Here’s my next chart showing atmospheric carbon dioxide as a solid blue line. Just for interest, I’ve also included a series of dotted lines showing how quickly CO2 was increasing in each of the last few decades. I’ve extended each of those out to 2030 so you can see at a glance how the CO2 curve keeps bending relentlessly upwards, decade after decade.

Accelerating towards the 450 ppm ‘guardrail’
Every major nation in the world has agreed that climate change must be limited to a maximum of +2oC in global warming. Beyond that point we risk destabilizing droughts, floods, mega-storms, heat waves, food shortages, climate extremes and irreversible tipping points. The best climate science says that staying below +2oC means we can’t exceed 450 ppm of CO2.
At the top of the chart I’ve highlighted this critical climate ‘guardrail’ of 450 ppm as a red line.
Notice how much faster we are approaching that danger line as the decades go by. Back in 1970, it seemed we had more than a century and a half to get a grip on climate pollution because CO2 was increasing much more slowly. But at our current rate we will blow through that guardrail in just 18 years. And, as we’ve seen, our “current rate” keeps accelerating.
Our foot-dragging at reducing climate pollution has left us in a dangerous situation with little time left to act. We’ve spent decades accelerating CO2 emissions to unprecedented extremes. We’ve blown our chance to deal gracefully with the climate and ocean crisis.
Global efforts so far
Beginning in 1995, the world’s nations have gathered every year to address the climate crisis. I’ve included all 22 of these annual meetings of the United Nations Conference of Parties (COP) on the chart above. Despite these decades of negotiations, plans, protocols and accords, CO2 is now increasing 60 per cent faster than when they first met.
Instead of slowing the rise of CO2, we’ve accelerated it.
What would Plan B for 2C look like?
Recently, two of the world’s premier energy agencies — International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA) — produced a joint report that tries to answer that question. Here’s the blunt summary:
“Limiting the global mean temperature rise to below 2°C with a probability of 66% would require an energy transition of exceptional scope, depth and speed. Energy-related CO2 emissions would need to peak before 2020 and fall by more than 70% from today’s levels by 2050 … An ambitious set of policy measures, including the rapid phase out of fossil fuel subsidies, CO2 prices rising to unprecedented levels, extensive energy market reforms, and stringent low-carbon and energy efficiency mandates would be needed to achieve this transition. Such policies would need to be introduced immediately and comprehensively across all countries … with CO2 prices reaching up to US dollars (USD) 190 per tonne of CO2.”
And here is their key chart showing annual energy-related CO2 emissions. Note the 50 percent surge since 1990 … and the need to reverse it by 2030.

Great Barrier Reef is Dying #auspol #qldpol 

‘terminal stage’: scientists despair at latest bleaching data
‘Last year was bad enough, this is a disaster,’ says one expert as Australia Research Council finds fresh damage 

 Two-thirds of Great Barrier Reef hit by back-to-back mass coral bleaching

 

Christopher Knaus and Nick Evershed

Monday 10 April 2017 07.01 AEST

Back-to-back severe bleaching events have affected two-thirds of Australia’s Great Barrier Reef, new aerial surveys have found.
The findings have caused alarm among scientists, who say the proximity of the 2016 and 2017 bleaching events is unprecedented for the reef, and will give damaged coral little chance to recover.
Scientists with the Australian Research Council’s Centre of Excellence for Coral Reef Studies last week completed aerial surveys of the world’s largest living structure, scoring bleaching at 800 individual coral reefs across 8,000km.
The results show the two consecutive mass bleaching events have affected a 1,500km stretch, leaving only the reef’s southern third unscathed.
It’s back to back, so there’s been zero time for recovery

Terry Hughes

Where last year’s bleaching was concentrated in the reef’s northern third, the 2017 event spread further south, and was most intense in the middle section of the Great Barrier Reef. This year’s mass bleaching, second in severity only to 2016, has occurred even in the absence of an El Niño event.

The Single Shining Hope To Stop Climate Change #auspol #qldpol #science 

Shining Hope to Stop Climate Change
By Michael E. Mann

TimeApril 9, 2017
It is the single shining hope to avoid the worst of global warming
Science is under attack at the very moment when we need it most.

 President Donald Trump’s March 28 executive order went much further than simply throwing a lifeline to fossil fuels, as industry-funded congressional climate changedeniers have done in the past. It intentionally blinded the federal government to the impacts of climate change by abolishing an interagency group that measured the cost of carbon to public health and the environment. 

Now, the government won’t have a coordinated way to account for damages from climate change when assessing the costs and benefits of a particular policy.
With that in mind, Trump should read the landmark “2020” report now published by Mission 2020, a group of experts convened by the former Executive Secretary of the United Nations Framework Convention on Climate Change.

 The report establishes a timeline for how we can ensure a safe and stable climate. 

We don’t have much time – 2020 is a clear turning point.

If emissions continue to rise beyond 2020, the world stands very little chance of limiting global warming below 1.5 degrees Celsius, the threshold set by the Paris Agreement, and a temperature limit that many of the world’s most vulnerable communities consider a threshold for survival. 

We have four years to bend the curve of global greenhouse gas emissions toward a steady decline.
The good news is, we’re already moving in the right direction. 

Global carbon emissions have plateaued, and are projected to remain flat over the coming years, thanks to China’s widespread economic transformation and the global boom in renewable energy production. 

The 2020 climate turning point is within reach.
But, as the authors of the report reveal, the bad news is we aren’t moving fast.

 Thankfully, there is a range of actions that, if achieved, can deliver a safe future. 

The study shows that by 2020, renewable energy must beat out coal in all major energy markets. 

Countries must commit to electrifying the transportation system, and transmission infrastructure must be built out to host efficient, low-carbon energy systems. 

Deforestation must be reigned in, and the restoration of already degraded land must be well underway. 

All of the Fortune 500 companies that represent heavy industries must have committed to the Paris targets, and their emissions-reduction plans must be in effect. 

And, finally, capital markets must double investment in zero-emission technologies.
Around the world, more and more politicians are listening to scientists. 

Nearly 200 heads of state adopted the Paris Agreement in December of 2015, and 136 have since ratified the deal in record time.

 Leaders in China and India have redoubled investments in renewables, and investors across the developed world are walking away from coal.

 And last fall, all 197 parties to the Montreal Protocol adopted a critical amendment that will phase down Hydrofluorocarbon, a particularly potent greenhouse gas.
Even in the United States, where public concern about climate is high but doubt of the scientific consensus on climate change has also spiked in recent years (I should know, having recently testified to the climate changedenying chair of the House Science Committee), and where the new Administration wants to stop funding climate science, many politicians are redoubling their commitment to climate action. 

From mayors of major cities to Congressional Republicans to the Defense Secretary, serious policy responses are being debated.


The only way to avoid dangerous climate change, and to keep the 1.5 degree Celsius target in play, is to step up our ambition by 2020, and deliver emissions reductions across all sectors.

 Only by drawing down global carbon emissions, by making sure that they drop steadily from 2020 forward, can we ensure that the world avoids the worst fates of climate change.
Science has no political affiliation and shouldn’t be a political issue.

 Chemistry and physics don’t care who is president or which party runs a parliament. 

No politician should ignore the warnings of scientists, economists and military leaders, and argue against health, increased stability and economic prosperity – all of which depend on how the world responds to climate change.
There is no denying it: 2020 will be a very important year.

Why We need Nikola Tesla to fight Climate Change #auspol #qldpol #science

By John F. Wasik

Nikola Tesla, the genius inventor of alternating current, radio and robotics, still provides uplifting guidance in this time of automation, climate change, globalization and political division.
Tesla died in 1943 at the age of 86, but his time has come again — particularly in light of the Trump administration’s decision earlier this week to roll back the progressive environmental policies that former President Barack Obama championed.
Adopting Tesla’s vision involves a new way of thinking about our relationship to the planet. Although great environmentalists like Teddy Roosevelt, John Burroughs and John Muir were articulating this new role during Tesla’s lifetime, world leaders today will also need to embrace Pope Francis’s radical “integral ecology.”

That means adopting a holistic approach to energy — intensive activities and tossing self-centered, widely held attitudes that takes man out of the center of his Ptolemaic universe.

Pope Francis, in his Laudato Si encyclical, doesn’t dispute the science behind climate change. The planet is getting hotter and man-made activities have some part in it. Last year was the hottest 12 months on record.
We need to get over ourselves and do something about the situation.
By “greening” all of the major systems of civilization — energy, transportation, manufacturing, building and consumer consumption — we can implement national networks of renewable energy and production.

Tesla was a firm believer in green energy. He supported hydro, geothermal and solar power more than 100 years ago. His vision for wireless power is still a major engineering challenge. Yet what if we produced clean energy from 24/7 sunlight in space and beamed it down to our planet? Many engineers are working on this problem across the world.
Although Tesla’s alternating current systems power most of the world’s electrical grid, he saw the dangers of burning fossil fuels to generate electricity. It’s still a massive problem contributing to global warming.
Since the earth is a closed-loop system, integral ecology recognizes the fact that we can’t keep extracting resources forever. A growing world population will demand more and more of the planet to sustain us.
As physicist and systems theorist Fritjof Capra writes:
“At the very heart of our global crisis lies the illusion that unlimited growth is possible on a finite planet…In this economic system, the irrational belief in perpetual growth is carried on relentlessly by promoting excessive consumption and a throwaway economy that is energy and resource intensive, generating waste and pollution, and depleting the Earth’s natural resources.”
How can we provide enough fertilizer and arable land to growing countries? How do we conserve water where it’s most needed? How do we switch over from burning fossil fuels in every country to a renewable portfolio of solar, wind, geothermal, biomass and hydrogen systems? How do we replace SUVs and McMansions with highly efficient, healthy homes?
All of these ideas have been on the table for decades, although progress has been made most notably in Northern Europe, which is working toward ambitious goals to free itself from fossil fuels and create a renewable energy grid.
The biggest obstacle to change has been our human-centered entitlement to global resources, which should be transformed to a responsible sharing of the commons, not an increasingly privatized resource. The earth can be managed more like a public library, not a buffet.
Ultimately, the almost immutable human mantra “it’s all about me” needs to be swapped with a shared prosperity and purpose “made up of simple daily gestures which break with the logic of violence, exploitation and selfishness,” the Pope notes.
Focus on quality of life over quantity of goods.

The most radical concept of all to be considered by world leaders? How to replace the damaging, universal dogma of economic growth with what the Pope calls “authentic humanity.”
That means more efficient and hospitable cities that embrace the poor, smaller/local commerce, better public transportation, respect for all species, and a new focus on quality of life over quantity of goods.

In crafting a truly integral approach that treats ecology, economics and ethics as points on an equilateral triangle, we’ll not only be addressing climate change, but safeguarding our deeper spiritual journey on this bountiful planet. Since Tesla was fervent advocate of world peace, he would’ve endorsed this worldview.
But to achieve this mission, we need to adhere to some of Tesla’s principles. We must visualize, conceptualize, and create solutions, then aggressively collaborate to make them blossom. Ecology is about relationships, but nothing can happen without consensus and cooperation.

The Age of Consequences #auspol 

“We are not your traditional environmentalists.” Gen. Gordon Sullivan (Retd), Fmr. Chief of Staff, U.S. Army
Four Corners brings you the views of distinguished former members of the US military and senior policy makers who warn that climate change is not only real, it’s a threat to global security.
“I’m here today not only representing my views on security implications of climate change, but on the collective wisdom of 16 admirals and generals.” Rear Admiral David Titley (Retd), U.S. Navy
They say climate change is impacting on vital resources, migration patterns and conflict zones.

“Climate change is one of the variables that must be considered when thinking about instability in the world.” Gen. Gordon Sullivan (Retd), Fmr. Chief of Staff, U.S. Army
Rear Admiral David Titley spent 32 years in the US military. He was the US Navy’s chief oceanographer and led the Navy’s Task Force on Climate Change. He argues climate change must be acknowledged.
“Our collective bottom line judgement is that climate change is an accelerating risk to our nation’s future.” Rear Admiral David Titley (Retd), U.S. Navy
The film analyses the conflict in Syria, the social unrest of the Arab Spring, and the rise of groups like ISIS and how these experts believe climate change is already acting as a catalyst for conflict.

“This is the heart of the problem in many ways. Climate change arrives in a world that has already been destabilised.” Dr Christian Parenti
Director Jared P Scott explores how water and food shortages, drought, extreme weather and rising sea-levels can act as accelerants of instability.
“We realised that climate change would be a threat multiplier for instability as people become desperate, because they have extreme weather and the seas are rising, and there are floods in one area and droughts in another, fragile states become more unpredictable.” Sherri Goodman, Fmr. Dept Undersecretary of Defense
These Pentagon insiders say a failure to tackle climate change, conducting ‘business as usual’, would lead to profound consequences.
“It’s a very dangerous thing to decide that there is one and only one line of events heading into the future and one and only one best response for dealing with that.” Leon Fuerth, Fmr. National Security Adviser, White House ’93-’01
