Climate change: Key UN finding widely misinterpreted

Science
Mario TamaA key finding in the latest IPCC climate report has been widely misinterpreted, according to scientists involved in the study. In the document, researchers wrote that greenhouse gases are projected to peak "at the latest before 2025".This implies that carbon could increase for another three years and the world could still avoid dangerous warming. But scientists say that's incorrect and that emissions need to fall immediately.Coral reefs mapped to tackle climate change threatCOP26 promises will hold warming under 2CHow Russia's war threatens Brazil's indigenous landThe IPCC's most recent report focused on how to limit or curtail emissions of the gases that are the root cause of warming.In their summary for policymakers, the scientists said it was still possible to avoid the most d...

COP26: Coal compromise as leaders near climate deal

Science
Getty ImagesA draft agreement at the COP26 climate summit has watered down commitments to end the use of coal and other fossil fuels, as countries race to reach a deal after two weeks of talks. While the language around fossil fuels has been softened, the inclusion of the commitment in a final deal would be seen as a landmark moment.A deal must be agreed by the end of the summit, which is in its final hours.The UN meeting is seen as crucial for limiting the effects of global warming.The draft agreement, which was published early on Friday following all-night talks, also asks for much tighter deadlines for governments to reveal their plans to reduce greenhouse gas emissions. And it also strengthens support for poorer countries fighting climate change.Negotiations over a final deal could str...

Climate Change: Don’t sideline plastic problem, nations urged

Science
Getty ImagesScientists are warning politicians immersed in climate change policy not to forget that the world is also in the midst of a plastic waste crisis. They fear that so much energy is being expended on emissions policy that tackling plastic pollution will be sidelined. A paper from the Zoological Society of London (ZSL) and Bangor University says plastic pollution and climate change are not separate.It says the issues are actually intertwined - and each makes the other worse. Manufacturing plastic items adds to greenhouse gas emissions, while extreme weather such as floods and typhoons associated with a heating planet will disperse and worsen plastic pollution in the sea.The researchers highlight that marine species and ecosystems, such as coral reefs, are taking a double hit from...
