The Quest To Save The World’s Coral #StopAdani #Auspol #Qldpol 

Coral reefs are the “rainforests of the sea”, prized for their beauty and resources the world over. They are also one of the Earth’s most vulnerable ecosystems threatened by climate change. And no place better symbolises their importance and their plight than Australia’s Great Barrier Reef.

The Great Barrier Reef covers 345,000 square kilometres, roughly the size of Germany, and stretches 2300km in length, nearly equal to the entire coastline of Chile.
If we continue on our current pathway where we’re pumping CO2 into the atmosphere, we’re acidifying the oceans, we won’t have coral reefs within 20, 30, 40 years from now.

Ove Hoegh-Guldberg, director, Global Change Institute
While coral reefs cover less than two percent of the ocean floor, nearly 25 percent of all marine life depends on them for survival.
Because it’s a living structure, it can also die. According to the World Resources Institute (WRI), nearly all coral reefs worldwide will be threatened with death by 2050.
“There are multiple stressors that face coral reefs like the Great Barrier Reef. There’s sediments and nutrients flowing down rivers and smothering corals and other organisms. There has been too much fishing in some cases where we’ve knocked down key species. But the real ‘show-stoppers’ now are the global changes that we’re inflicting on coral reefs,” explains Ove Hoegh-Guldberg, director of The Global Change Institute.

According to WRI, the absorption of an increased level of atmospheric carbon dioxide into the oceans has caused them to become more acidic. This change in water chemistry inhibits the ability of corals, whose skeletons are composed of calcium carbonate, to grow. Higher water temperatures also affect the ecology of the reefs and turn the coral white, a process known as “coral bleaching.”
Scientific models show both ocean acidification and ocean temperatures spiking to unprecedented levels over the next 100 years.
A group of scientists just outside of Townsville are fighting to save the coral reefs – not just from bleaching events now, but also from the effects of climate change yet to come.
Researchers at Australia’s National Sea Simulator aquarium brought the ocean to their lab to replicate and manipulate ocean conditions in a controlled environment.
“So what this experiment is, is we’re looking at current day conditions, and we’re looking at conditions that are projected by the IPCC, which is the intergovernmental panel on climate change, conditions which are predicted for the year 2050 and then conditions which are predicted for the year 2100,” says Nicole Webster.

Saving the coral reef

Researchers are seeking to determine not just whether corals can be conditioned to withstand future ocean conditions, but whether those manipulated corals can pass those survival traits on to future generations – a process known as assisted evolution.
For Ove Hoeugh-Guldberg and other scientists, the threat to coral reefs goes beyond science. More than two million people visit the Great Barrier Reef every year, a $6bn a year industry supported by over 16,000 employees.
“When you take what coral reefs represent to people, this is amazing numbers right, there’s an estimated 500 million people on the planet who come to coral reefs almost on a daily basis to get food and income. Now, that’s about one in every 12 people dependent on coral reefs worldwide,” says Hoeugh-Guldberg.

Climate change: farmers urge Coalition to restore emissions trading scheme.

Failure to acknowledge the problem is ‘doing the industry a disservice’ and harming Australia’s international standing, says farming group.

A delegation of farmers has called for the Abbott government to act on climate change by restoring an emissions trading scheme, maintaining the current renewable energy target and spending on rail infrastructure to improve inland transport and reduce carbon emissions.

The farmers have spent two days lobbying the Coalition to start implementing a suite of policies to deal with the effects of climate change, warning of dire consequences for the agriculture sector if the threat was not addressed.

They have told the government MPs, including John Cobb and the staff of the treasurer Joe Hockey, that the Direct Action policy, which provides incentives for polluters to reduce carbon emissions, will not work to ameliorate climate change, “but if the government wants to give away money, people will keep taking it”.

The delegation said the lack of climate policies was being exacerbated by the cuts to research and development funding for applied climate science and the Bureau of Meteorology.

negotiations between the government and Labor continued over the RET, which currently requires the government to source 41,000 gigawatt hours of energy from renewables by 2020. The latest government offer to Labor is 32,000GWh.

It also follows a report by University of Melbourne researchers called Appetite for Change, which charted the detrimental effects of climate change on Australia’s food production.

Pharrell to the UN: ‘It’s time to go from climate change to climate action.

UNITED NATIONS (Thomson Reuters Foundation) – It’s time to go “from climate change to climate action” in efforts to save the planet, U.S. pop star Pharrell Williams said at the United Nations on Friday.

Singer-producer Williams, 41, partnered with the United Nations Foundation on the International Day of Happiness to raise awareness and call for more action on climate change.

“If you look at our behaviour is hard to believe we’re all aware we only have one planet,” Williams said in a General Assembly hall crowded with young people. “My main inspiration for being here today is that we’re in trouble, but we can change that. This earth is our home.”

The star is the creative director of the Live Earth movement, which campaigns for a climate deal to be reached before a global summit takes place in Paris in December.

“On this day we are using the universal language of music to show solidarity with the millions of people around the world suffering from poverty, human rights abuses, humanitarian crises and the effects of environmental degradation and climate change,” United Nations Secretary General Ban Ki-moon said in a video message.

As the event wrapped up, the audience got up and started dancing to “Happy”.

Williams later greeted young fans who swarmed the General Assembly hall’s stage, sending U.N. security momentarily into panic as it struggled to contain the wave of screaming young people and their parents.

5 Ways to Reduce the Drivers of Climate Change

World Bank Group President Jim Yong Kim gave a lecture at Georgetown University on March 18, 2015, about the development challenges created by climate change and actions that can be taken now to reduce the drivers of climate change and the impact.

Climate change is fundamentally a development issue. It threatens to exacerbate poverty and hurt economic growth. At the same time, how countries grow and the investments they make to meet the energy, food and water needs of an expanding population can fuel climate change, raising risks worldwide, or contribute to solutions.

In a lecture to students at Georgetown University in Washington, D.C., on March 18, World Bank Group President Jim Yong Kim laid out five key areas where policies and growth choices can help reduce the drivers of climate change.

“We have to keep the economy growing – there is no turning back on growth,” President Kim told the student audience. “What we have to do is decouple growth from carbon emissions.”

Put a price on carbon

Cutting emissions starts with clear policy signals.

Carbon pricing systems – such as emissions trading systems that cap emissions or carbon taxes that charge per ton – send a long-term signal to companies by creating an incentive to reduce polluting behaviors and to invest in cleaner energy choices and low-carbon innovation.

End fossil fuel subsidies

Fossil fuel subsidies send a different signal – one that can encourage waste and discourage low-carbon growth. By phasing out harmful fossil fuel subsidies, countries can reallocate their spending to where it is most needed and most effective, including proving targeted support for the poor.

Build low-carbon, resilient cities

Getting prices right is one part of the equation. Another piece is building a sustainable future, because all development happens in the context of climate change.

There will be more infrastructure built in the next 20 years than in the past 6,000, the president told the audience.  Cities are growing fast, particularly in the developing world. Just over half the global population is urban today; by 2050, cities are expected to hold two-thirds of the world population.

Increase energy efficiency and use of renewable energy

When we talk about energy, we have to talk about access. Worldwide, about 1.2 billion people lack access to electricity and 2.8 billion rely on solid fuels for cooking, such as wood, charcoal, and coal, which cause harmful indoor air pollution.

Through the Sustainable Energy for All initiative, the World Bank Group support three goals for 2030:  achieve universal access to modern energy, double the rate of improvement in energy efficiency, and double the share of renewable energy in the global energy mix.

Energy efficiency improvements are crucial. Every gigawatt saved is a gigawatt that didn’t have to be produced. Globally, energy use is about one-third lower today than it would have been without the past 20 years of energy efficiency improvements.

Implement climate-smart agriculture and nurture forest landscapes

The fifth area for action takes in both mitigation and adaptation. Climate-smart agriculture techniques help farmers increase their farms’ productivity and resilience to the impacts of climate change, such as droughts, while also creating carbon sinks that help reduce net emissions. Forests, too, are valuable carbon sinks that absorb carbon and store it in soils, trees, and foliage.

Tesla drivers will be able to drive “anywhere in Australia”. 

Tesla CEO Elon Musk says eventually Australian Tesla drivers will be able to drive “anywhere in Australia” without being too far from a charging station, as he announced a new major software update.

The enigmatic entrepreneur  told journalists in a conference call at 3am AEDT overnight that Tesla sales in Australia had been “surprisingly good,” leading to further “significant investment” from his US company.

“Sydney to Melbourne is a key route for us,” Mr Musk said, adding that within 12 months ‘Southern Australia’ will be fully connected to Tesla’s supercharger network.

Great Barrier Reef an ‘unfolding disaster’ as World Heritage Site is on brink of collapse.

The Great Barrier Reef is an “unfolding disaster”, with the Australian government “going backwards” on climate change, an expert has said. In a report published in the journal Science, researchers have said World Heritage sites across the globe are at risk of collapse from climate change because of poor local management.

An international team of researchers looked at how mismanagement problems are affecting World Heritage areas including the Great Barrier Reef, the Amazon rainforest and the Doñana wetlands in southern Spain.

They found that localised issues – such as declining water quality through pollution or deforestation – can increase the effects of climate extremes like droughts. This further reduces the ecosystem’s ability to cope with climate change impacts.

The Great Barrier Reef is currently under threat from ocean acidification and coral bleaching, brought about through CO2 emissions. Localised threats such as overfishing, nutrient runoff, and dredging reduces the reef’s ability to cope with the bleaching and acidification.

Terry Hughes, director of the Australian Research Council Centre of Excellence for Coral Reef Studies and co-author of the study, said: “It’s an unfolding disaster. The reef needs less pollution from agricultural runoff and port dredging, less carbon dioxide emissions from fossil fuels, and less fishing pressure. Ironically, Australia is still planning to develop new coal mines and expand coal ports, despite global efforts to transition quickly towards renewable energy. As a wealthy country, Australia has the capability and responsibility to improve its management of the reef.”

Report’s dire warning for food production as climate becomes warmer.

A report which examines the effect of climate change on some of Australia’s most common agricultural products; including fruits, vegetables, grains, dairy, seafood and meat, paints a dire prediction of future production in a warming world.

The Appetite for Change study suggests farming will need to relocate to new regions and find new drought-tolerant varieties or face much reduced, or poorer quality yields for many of the country’s key agricultural products.

Richard Eckard, the director of the Primary Industries Climate Challenges Centre, based at Melbourne University, said Australian farmers faced a critical turning point and needed to act now.

The Intergenerational Report underestimates climate threat: an open letter to the government

initiated by Dr Andrew Glikson, signed by Australian environmental and climate scientists.

We the undersigned are concerned that the 2015 Intergenerational Report underestimates the serious threat of global warming to future generations.

Based on the basic laws of physics, direct measurements and empirical observations in nature, the current rise in atmospheric greenhouse gases by about 40% since the 19th century is inducing a shift in the state of the atmosphere-ocean-land-ice sheets system, seriously endangering future generations, and indeed nature’s life-support systems.

Our concern is based on the peer-reviewed scientific literature, as summarised by the Intergovernmental Panel on Climate Change and on observations by the world’s national science academies and geophysical research societies of leading nations, including Australia.*

The current and projected trend in CO2 from the 19th century concentration of 280 parts per million (ppm) to the present 400 ppm, currently rising at more than 2 ppm per year, threatens to transform the planetary climate, creating conditions in which large parts of the continents become subject to droughts, fires and other extreme weather events. If this trend is allowed to continue, low coastal and river valleys, where much of the world’s population lives and where its food supply is produced, would be inundated by rising sea levels.

At the current rates of CO2 emissions, by 2055 (the projected date in the Intergenerational Report) CO2 concentrations would rise to about 480 ppm, threatening the Antarctic and Greenland ice sheets and approaching conditions that existed on the planet more than 2.6 million years ago, before the appearance of the genus Homo.

Australia has many excellent renewable and low-carbon energy resources and access to commercially available technologies that would enable Australia to transition to zero-carbon electricity within two to three decades, given the political will. This zero-carbon electricity system would be reliable, affordable and job-creating.

We call on the Australian government, and indeed the governments of all nations, to reconsider the consequences of ongoing emission of greenhouse gases and, as a matter of urgency, promote much more rapid transition to non-polluting energy-generating methods.

10 myths about fossil fuel divestment put to the sword.

1. Divestment from fossil fuels will result in the end of modern civilisation

It is true that most of today’s energy, and many useful things such as plastics and fertilisers, come from fossil fuels. But the divestment campaign is not arguing for an end of all fossil fuel use starting tomorrow, with everyone heading back to caves to light a campfire. Instead it is arguing that the burning of fossil fuels at increasing rates is driving global warming, which is the actual threat to modern civilisation. Despite already having at least three times more proven reserves than the world’s governments agree can be safely burned, fossil fuel companies are spending huge sums exploring for more. Looked at in that way, pulling investments from companies committed to throwing more fuel on the climate change fire makes sense.

2. We all use fossil fuels everyday, so divestment is hypocritical

Again, no-one is arguing for an overnight end of all fossil fuel use. Instead, the 350.org group which is leading the divestment campaign calls for investors to commit to selling off their coal, oil and gas investments over five years. Fossil fuel burning will continue after that too, but the point is to reverse today’s upward trend of ever more carbon emissions into a downward trend of ever less carbon emissions. Furthermore, some of those backing a “divest-invest” strategy move money into the clean energy and energy efficiency sectors which have already begun driving the transition to a low-carbon world.
