An article in The Guardian<\/a> by Adam Morton and Graham Readfearn, 9th August 2021

Australian scientists have stressed it is \u201cnot too late\u201d to take action to stem the worst of the climate crisis and called on leaders to \u201cwake up\u201d after a landmark global science report found widespread and rapid changes were already occurring across the planet.<\/p>\n\n\n\n

The latest assessment by the Intergovernmental Panel on Climate Change<\/a>, the world\u2019s leading authority on climate science, found human activities were unequivocally heating the planet and causing changes not seen for centuries and in some cases thousands of years.<\/p>\n\n\n\n

Human-induced climate change is already affecting weather and climate extremes in every region across the globe, helping cause increased heatwaves, heavier rainfall events and more intense droughts and tropical cyclones, the report found.<\/p>\n\n\n\n

In Australia, it found average temperatures above land had already increased by about 1.4C since 1910. Annual changes in temperature were now above what could be expected from natural variation in all regions across the continent.<\/p>\n\n\n\n

A regional fact sheet released alongside the report said heatwaves and dangerous fire weather had increased, the bushfire season had become longer, and marine heatwaves were more common. Sea levels were rising faster in Australia than the global average and sandy shorelines were already retreating in many areas.<\/p>\n\n\n\n

As the century goes on and temperatures and emissions rise further, heat extremes and heavy rainfall events were projected to increase, and there would be more sand and dust storms. The impact of the La Nina and El Ni\u00f1o cycles on Australia\u2019s rainfall \u2013 which has fallen across the southern part of the continent, particularly in Western Australia \u2013 were expected to become even more pronounced. Droughts affecting ecosystems and agriculture would probably increase as global warming hits 2C.<\/p>\n\n\n\n

Globally, the report found temperatures would continue to increase until at least mid-century under all future scenarios. It also found global heating of 1.5C and 2C above pre-industrial levels \u2013 the benchmarks referred to in the Paris agreement \u2013 would be exceeded this century unless there were deep reductions in carbon dioxide and other greenhouse gases.<\/p>\n\n\n\n

Cop26 summit crucial<\/h2>\n\n\n\n

Dr Jo\u00eblle Gergis, of the Australian National University and a lead author of the report\u2019s chapter on changes in rainfall, said 1.5C was \u201cvery likely\u201d to be breached by the early 2030s. She said the report should be \u201ca wake-up call for the world\u201d ahead of the UN\u2019s Cop26 climate summit scheduled for Glasgow in November.<\/p>\n\n\n\n

\u201cWhat happens there determines the future of humanity,\u201d she said.<\/p>\n\n\n\n

\u201cIf this report, and the evidence from around the world right now, does not convince this generation of political leaders that we have to stabilise the climate then I don\u2019t think anything else will. This is as clear as we can be. Now it\u2019s up to our political leaders to act.\u201d<\/p>\n\n\n\n

Dr Pep Canadell, a coordinating lead author of a chapter of the IPCC report and the director of the Global Carbon Project based at CSIRO, said the report showed humans were \u201cstill in the control cabin of the planet and climate system\u201d, but may not be unless there was urgent action to cut emissions.<\/p>\n\n\n\n

He said the \u201cfingerprint of humans\u201d was already clear in climate extremes and weather events, including floods, heatwaves and fires.<\/p>\n\n\n\n

\u201cEvery decimal of a degree that we are avoiding is a win for us and a win for the planet,\u201d Canadell said. \u201cThe important thing to understand is there is no bottom end to how much damage we can create.\u201d<\/p>\n\n\n\n

Shayne McGregor, an associate professor at Monash University and another report lead author, said a key message was that it was \u201cnot too late\u201d to act. He said large-scale, rapid and sustained emissions reductions were needed.<\/p>\n\n\n\n

\u201cI think there\u2019s this idea that once we get to 1.5C it\u2019s some kind of cliff edge [but] every action we do moving forward is beneficial,\u201d he said. \u201cEvery half a degree or 0.1 of a degree of warming we can reduce or minimise, the better off we are.\u201d<\/p>\n\n\n\n

The Australian emissions reduction minister, Angus Taylor, said the report reinforced the need for \u201ca coordinated, global effort to reduce emissions\u201d. Taylor said the government was committed to achieving net zero emissions as soon as possible and preferably by 2050 \u2013 slower than the change scientists say is needed in global emissions to avoid temperature degrees well above 2C.<\/p>\n\n\n\n

He said the Morrison government was committed to its 2030 commitment of a 26-28% cut in emissions compared with 2005 levels.<\/p>\n\n\n\n

The Greens said the IPCC report made it clear the government\u2019s current 2030 target was a \u201cdeath sentence\u201d for Australia. Scientists have previously advised Australia cut emissions by at least 50% by 2030 for the country to place its part in attempting to breach the goals of the Paris agreement.<\/p>\n\n\n\n

\"The<\/a><\/figure>\n\n\n\n

Labor\u2019s climate spokesperson, Chris Bowen, said the report was \u201cyet more evidence of the costs of inaction, and it\u2019s past time the government stop spinning and start delivering for Australians\u201d. He said a \u201cbare minimum\u201d commitment should be committing to net zero emissions by 2050.<\/p>\n\n\n\n

\u201cAustralians deserve better than a government that tries to spin its way through as about 70% of global GDP decarbonises, and existing export markets dry up,\u201d Bowen said.<\/p>\n\n\n\n

Adam Bandt, the leader of the Greens, said the report exposed the \u201cstark reality\u201d that without emergency action the globe would head beyond 1.5C of warming, potentially within a few years. He called on the government to \u201cdouble or triple\u201d its 2030 targets.<\/p>\n\n\n\n

\u201cThe rest of the world understands that if we don\u2019t do more by 2030, we all go over the climate cliff, so the Liberals\u2019 2030 denial and Labor\u2019s 2030 silence are putting Australian lives at risk,\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":"
