Most emissions scenarios under the United Nations Intergovernmental Panel on Climate Change (IPCC) envision the world breaching 1.5C during the 2030s. Earth sensitivityThe study's findings, published in the journal Oxford Open Climate Change, result from two factors. The IPCC has given a best-guess estimate that the doubling of atmospheric carbon dioxide levels would yield global warming of around 3C (5.4F). Cleaning the skies, while bringing health benefits and saving lives, accelerates climate change. Earlier this week, research published in the journal Nature Climate Change suggested the world would need to reach net zero emissions by 2034 for a 50% chance of containing warming to 1.5C - far sooner than the global goal of 2050.
