“The global average temperature will rise 2.7 degrees Celsius by century’s end even if all countries meet their promised emissions cuts, a rise that is likely to worsen extreme wildfires, droughts and floods, the United Nations said in a report on Friday.
That level of warming, measured against preindustrial levels, is likely to increase the frequency of deadly heat waves and threaten coastal cities with rising sea levels, the country-by-country analysis concluded.
The United Nations Secretary General António Guterres said it shows “the world is on a catastrophic pathway.”
Perhaps most starkly, the new report displayed the large gap between what the scientific consensus urges world leaders to do and what those leaders have been willing to do so far. Emissions of planet-warming gases are poised to grow by 16 percent during this decade compared with 2010 levels, even as the latest scientific research indicates that they need to decrease by at least a quarter by 2030 to avert the worst impacts of global warming.”
