The “window is narrowing” to limit global warming to 1.5C, with a new United Nations report warning the Earth has already warmed by 1.1C above pre-industrial levels and is on track to cross the threshold within the next decade. Despite the grim prediction, the latest report released yesterday by the Intergovernmental Panel on Climate Change (IPCC) says there’s still an opportunity to meet the target if there is “significant global effort”, particularly from wealthier nations, including Oz. The IPCC said that would require slashing 60% of the world’s carbon emissions by 2035. But UN Secretary-General Antonio Guterres took things a step further, calling on richer nations to bring forward their net zero goals by a decade to 2040, quit using coal, oil and gas by 2030 and stop all new fossil fuel projects. Long story short, the pressure is on nations to bring more ambitious climate commitments to the COP28 climate summit in November.
