Study: IPCC’s Worst-Case Scenarios Already Off-Track
earth fire disasterUnder the worst-case scenarios laid out in the United Nations’ climate change projections, global temperatures could increase as much as 7.2 degrees Fahrenheit (more than 4 degrees Celsius) by 2100, leading to as much as 3 feet (0.98 meters) in global sea-level rise and an array of disastrous consequences for people and planet.
But new research from CU Boulder finds that these high-emissions scenarios, used as baseline projections in the UN’s Intergovernmental Panel on Climate Change (IPCC) global assessments, have not accurately reflected the slowing rate of growth in the global economy and we are unlikely to catch up to them anytime soon.
The new study, published today in Environmental Research Letters, is the most rigorous evaluation of how projected climate scenarios established by the IPCC have evolved since they were established in 2005.
