It was one other shattering yr.
Climate change amped up climate extremes across the globe, smashing temperature data, sinking river ranges to historic lows and elevating rainfall to devastating highs. Droughts set the stage for wildfires and worsened meals insecurity. Researchers discovered themselves pondering the boundaries of people’ capability to tolerate excessive warmth (SN: 7/27/22).
The excessive occasions from 2022 pinpointed on the map beneath are only a pattern of this yr’s local weather disasters. Each was exacerbated by human-caused local weather change or is consistent with projections of regional impacts.

In its Sixth Assessment Report, launched in 2021 and 2022, the United Nations’ Intergovernmental Panel on Climate Change, or IPCC, warned that people are dramatically overhauling Earth’s local weather (SN: 8/9/21). Earth’s common floor temperature has already risen by at the least 1.1 diploma Celsius since preindustrial instances, because of human inputs of heat-trapping gases to the environment, notably carbon dioxide and methane (SN: 3/10/22). That warming has shifted the circulation of power across the planet, altering climate patterns, elevating sea ranges and turning previous extremes into new normals (SN: 2/1/22).
And the world should climate extra such local weather extremes as carbon retains accumulating within the environment and international temperatures proceed to rise. But IPCC scientists and others hope that, by highlighting the regional and native results of local weather change, the world will ramp up its efforts to scale back climate-warming emissions — averting a extra disastrous future.
