Earth has just experienced its hottest Northern Hemisphere summer on record, with August being the hottest month ever recorded by modern equipment. The average temperature in August was 1.5 degrees Celsius (2.7 degrees Fahrenheit) higher than pre-industrial averages, leading to extreme weather events such as heat waves, droughts, and wildfires. The WMO and C3S have urged governments to take action to reduce emissions and mitigate the effects of climate change, and U.S. President Joe Biden has promised federal aid for Idalia recovery.
