UN: humans contribute to sharp warming across planet

Earth’s climate is getting so hot that temperatures in about a decade will probably blow past a level of warming that world leaders have sought to prevent, according to a report released Monday that the United Nations calls a “code red for humanity.” The authoritative Intergovernmental Panel on Climate Change (IPCC) report, which calls climate change clearly human-caused and “unequivocal,” makes more precise and warmer forecasts for the 21st century than it did last time it was issued in 2013. The report said, the world will cross the 1.5 degrees Celsius warming mark in the 2030s, earlier than some past predictions.
