Siberia experiences worst heat wave in history with record-breaking temperatures.

Siberia is experiencing its worst heat wave in history, with dozens of temperature records broken and temperatures reaching above 100 degrees Fahrenheit. The region has seen a strong warming trend in recent decades, and climate experts warn that extreme heat waves will continue to happen more frequently unless greenhouse gas emissions are rapidly cut. The heat is also likely to worsen wildfires, which have already been significant and intense in Siberia and Canada. The heat wave has spread across Central Asia, with temperatures reaching historic highs in several countries.
