March temperatures in Central Asia were up to 10 degrees Celsius (18 degrees Fahrenheit) hotter than the pre-industrial average, according to World Weather Attribution, a coalition of scientists that studies the impact of climate change on extreme weather events.

The region spans several climate zones but typically experiences hot, dry summers and cold, harsh winters.
