New UN climate report is a ‘Code Red for Humanity’

By Reynard Loki – In a grim report released on August 9, the Intergovernmental Panel on Climate Change (IPCC) says that climate change was “unequivocally” caused by human activity, and that within two decades, rising temperatures will cause the planet to reach a significant turning point in global warming. The report’s authors—a group of the world’s top climate scientists convened by the United Nations (UN)—predict that by 2040, average global temperatures will be warmer than 1.5 degrees Celsius above pre-industrial levels, causing more frequent and intense heat waves, droughts and extreme weather events. UN Secretary-General António Guterres called the bleak findings a “code red for humanity.”

The report found global warming increasing at a faster rate than earlier predictions estimated. “It is unequivocal that human influence has warmed the atmosphere, ocean and land… [and] at a rate that is unprecedented in at least the last 2,000 years,” the report says. “Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred.” Even if the world’s nations enacted sharp and stringent reductions in the emissions of greenhouse gases today, overall global warming is still estimated to rise around 1.5 degrees Celsius within the next 20 years. That means that the hotter, more dangerous future that scientists and the Paris climate agreement sought to avoid is now unavoidable.

Linda Mearns, a senior climate scientist at the US National Center for Atmospheric Research and one of the report’s co-authors, offered a stern warning: “It’s just guaranteed that it’s going to get worse,” she said, adding that there is “[n]owhere to run, nowhere to hide.” In an interview with the Hill, Kim Cobb, the lead author of the report’s first chapter, said, “We’re already reeling, clearly, from so many of these impacts that the report highlights, especially in the category of extremes that are gripping these headlines and causing so much damage, but of course the 1.5 degree C world is notably and discernibly worse.” more>
