Cooling needed!

On November 6, the 27th World Climate Change Conference kicked off in Sharm El-Sheikh, Egypt - at a time when man-made global warming continues to advance. Efforts are still underway to meet the agreed 1.5-degree target. Releasing less carbon dioxide (CO2) into the atmosphere is the main countermeasure. But there is another set screw: short-lived climate-altering substances such as methane, soot and ozone. They, too, are part of the big picture. If these substances were reduced, warming could be reduced by about 0.8 degrees Celsius. Jülich atmospheric scientist Prof. Astrid Kiendler-Scharr was lead author of the chapter on short-lived climate pollutants in the latest report of the Intergovernmental Panel on Climate Change.

In August 2021, the Intergovernmental Panel on Climate Change (IPCC) published the first part of its latest assessment report. The verdict is clear: climate change is progressing rapidly, and every region of the world is already affected. Without immediate and comprehensive countermeasures, our atmo­sphere is likely to warm to 1.5 degrees Celsius above the pre-industrial temperature over the next 20 years. The consequences of the currently plus 1.1 degrees are already showing up in weather extremes such as heat waves, droughts or heavy rain.
