As World Busts Heat Records, Study Warns Global Warming Could Be Twice as Bad Climate Models Project

Study co-author Katrin Meissner of University of New South Wales, Australia remarked that “while climate model projections seem to be trustworthy when considering relatively small changes over the next decades, it is worrisome that these models likely underestimate climate change under higher emission scenarios, such as a ‘business as usual’ scenario, and especially over longer time scales.”

A team of 59 researchers from 17 countries assessed previous warm periods over the past 3.5 million years and found that during each of the three intervals analyzed, the rate of warming was much slower compared with the changes seen today—which are driven by burning fossil fuels that release heat-trapping greenhouse gases. As Meissner put it, “In terms of rate of change, we are in uncharted waters.”
