Temperature rising by 1.5C likely in near term unless world acts now, UN says

Live Mint  

The report published today by the world’s leading climate science body, the UN Intergovernmental Panel on Climate Change, summarizes the panel’s output over the past five years, amounting to some 10,000 pages of dense scientific prose. “This report is a clarion call to massively fast-track climate efforts by every country and every sector and on every timeframe,” said UN Secretary General António Guterres in a statement on the report’s release. “In short, our world needs climate action on all fronts — everything, everywhere, all at once.” The report underscores a handful of points about climate change and its impacts: Greenhouse gas emissions generated by human activity have unequivocally caused global warming, and emissions have continued to rise, with some countries and groups contributing far more than others. Although policies to mitigate climate change have expanded, it’s likely that the world will exceed 1.5C of warming “in the near term.” Limiting warming to 1.5C or 2C will require deep emissions cuts across the economy this decade. Nations aren’t powerless to limit future destruction: “Feasible, effective, and low-cost options for mitigation and adaptation are already available, with differences across systems and regions.” Solar and wind energy, electric vehicles and green urban infrastructure bring additional benefits such as lower levels of air pollution.
