Extreme Weather in 2022 Showed Global Impact of Climate Change
Droughts set the stage for wildfires and worsened food insecurity. Researchers found themselves pondering the limits of humans’ ability to tolerate extreme heat, the Sciencenews reported.
The extreme events from 2022 are just a sample of the climate disasters. Each was exacerbated by human-caused climate change or is in line with projections of regional impacts.
In its Sixth Assessment Report, released in 2021 and 2022, the United Nations’ Intergovernmental Panel on Climate Change, or IPCC, warned that humans are dramatically overhauling Earth’s climate.
Earth’s average surface temperature has already risen by at least 1.1 degree Celsius since preindustrial times, thanks to human inputs of heat-trapping gases to the atmosphere, particularly carbon dioxide and methane. That warming has shifted the flow of energy around the planet, altering weather patterns, raising sea levels and turning past extremes into new normals.
And the world will have to weather more such climate extremes as carbon keeps accumulating in the atmosphere and global temperatures continue to rise. But IPCC scientists and others hope that, by highlighting the regional and local effects of climate change, the world will ramp up its efforts to reduce climate-warming emissions — averting a more disastrous future.
