With 1.5\u00b0C Goal ‘Currently Not Plausible,’ Study Calls for Focus on Deep Social Change<\/span><\/a><\/h3>\n

“In order to be equipped for a warmer world, we have to anticipate changes, get the affected parties on board, and take advantage of local knowledge,” said one researcher.<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Scientists at the University of Hamburg in Germany argued Wednesday that meeting the 2015 Paris climate agreement’s goal of limiting planetary heating to 1.5\u00b0C is “currently not plausible”\u2014but warned that despairing over climate “tipping points” risks taking attention away from “the best hope for shaping a positive climate future… the ability of society to make fundamental changes.”<\/p>\n

The Hamburg Climate Futures Outlook assessed the planetary impacts of several “physical processes that are frequently discussed as tipping points.” These include the melting of sea ice in the Arctic and glaciers at the North and South Poles; the weakening of the\u00a0Atlantic Meridional Overturning Circulation (AMOC)<\/a>, the system of ocean currents that carries warm water upward into the North Atlantic; and “dieback” in the Amazon rainforest, in which rising temperatures would dry out trees and eventually change the forest landscape into a savanna, releasing billions of tons of stored carbon.<\/p>\n

Those scenarios “are serious developments,”\u00a0said<\/a>\u00a0researchers at the university, but the melting of ice “will have very little influence on the global temperature until 2050.” The weakening of AMOC and Amazon dieback will have a “moderately” greater influence on global temperatures.<\/p>\n

“Human agency has a large potential to shape the way climate futures will evolve.”<\/p>\n

“By extrapolating current trends,” reads\u00a0the study<\/a>, “permafrost thaw and Amazon Forest dieback are expected to release somewhat more than one year’s worth of today’s anthropogenic CO2 emissions between now and 2050. Thus, the contributions of these two processes to the remaining carbon budget are small…<\/p>\n
