In sweltering Brazil, worst-ever flooding killed dozens of people and paralyzed a city of about 4 million people. Voters and politicians in the world’s largest election in India are fainting in heat that hit as high as 115 degrees (46.3 degrees Celsius).

A brutal Asian heat wave has closed schools in the Philippines, killed people in Thailand and set records there and in Indonesia, Malaysia, the Maldives and Myanmar. Record temperatures — especially at night when it just won’t cool down — have hit many parts of Africa. Flooding devastated Houston, and the United States as a whole just had its second highest number of tornadoes for the month of April.

In a world growing increasingly accustomed to wild weather swings, the last few days and weeks have seemingly taken those environmental extremes to a new level. Some climate scientists say they are hard pressed to remember when so much of the world has had its weather on overdrive at the same time.
