Earth is On Track For Catastrophic Warming, UN Warns

The planet is on track for catastrophic warming, but world leaders already have many options to reduce greenhouse gas pollution and protect people, according to a major new climate change report from the United Nations. NPR: The report was drafted by top climate scientists and reviewed by delegates from nearly 200 countries. The authors hope it will provide crucial guidance to politicians around the world ahead of negotiations later this year aimed at reining in climate change. The planet faces an increasingly dire situation, according to the report. Climate change is already disrupting daily life around the world. Extreme weather, including heat waves, droughts, floods, wildfires and hurricanes, is killing and displacing people worldwide, and causing massive economic damage. And the amount of carbon dioxide accumulating in the atmosphere is still rising. "Climate change is a threat to human well-being and planetary health," the report states. "There is a rapidly closing window of opportunity to secure a liveable and sustainable future for all." But there are many choices readily available to policymakers who want to address climate change, the report makes clear. Those choices include straightforward, immediate solutions such as quickly adopting renewable sources of electricity and clamping down on new oil and gas extraction. They are also more aspirational ones, such as investing in research that could one day allow technology to suck carbon dioxide out of the air. The authors of the report are not prescriptive. No solution is held up as the "right" one. [...] The report lays out sobering facts about the state of the Earth's climate. The planet is nearly 2 degrees Fahrenheit warmer than it was in the late 1800s, and is on track to exceed 5 degrees Fahrenheit of warming by the end of the century, it warns.
