Inevitably, temperatures would soar even further.īy contrast, scientists say that if temperature rises can be kept below 1.5C, then the worst impacts of climate change could be prevented – though they also point out that temperatures have already risen 1.2C, leaving the world facing very tight margins to avoid the worst impacts of global warming over the next 30 years. In addition, loss of reflective ice from the poles could cause oceans to absorb more solar radiation, while melting permafrost in Siberia and other regions would release plumes of methane, another pernicious greenhouse gas.
“The research underlines what many of us fear: major economies are simply not doing enough to tackle the climate crisis and, in many cases, G20 countries are leaving us on track a world of more heatwaves, flooding and extreme weather events.”Ī world that would be 5C hotter than it was before the Industrial Revolution, when fossil-fuel burning began in earnest, would be one in which a quarter of the global population would face extreme drought for at least one month a year rainforests would be destroyed and melting ice sheets would result in dangerous sea-level rises. This point was backed by Yann Robiou du Pont, the lead researcher for the Paris Equity Tracker analysis. The G20 meeting had been viewed as a critically important staging post leading up to Cop26 and its failure to find common ground underlines the crucial differences that divide nations in the group and indicate it is not going to be easy to secure a meaningful accord in Scotland. “The G20 is failing to deliver,” said the online activist network Avaaz. The stark difference between the climate plans of different G20 nations – who together are responsible for 85% of all global carbon emissions – was underlined last week in Naples, when a meeting of member states’ energy and environment ministers ended with the group failing to agree on a package of commitments to tackle climate change.
