July 2022 European heat wave (week 2)

In 2022, several areas of the world experienced heat waves. Heat waves were especially notable in East Asia, the Indian subcontinent, Australia, western Europe, the United States, and southern South America. 2022 heat waves accounted for record-breaking temperatures and, in some regions, heat-related deaths. Heat waves were worsened by the effects of climate change, and they exacerbated droughts and wildfires.

Background and effects

Due to climate change, heat waves and other extreme weather events are longer and more intense. In many places, heat waves were accompanied by droughts and wildfires.

Heat waves and droughts affected water supplies, rivers (along with shipping and nuclear reactor cooling), ecosystems, various global supply chains, health, and agriculture worldwide.

A historic heat wave affected the Midwest and Southeast in the second week of June. On 13 June, more than 125 million people under excessive heat warnings. Following a brief respite 18 June, the heat wave returned into the following days.

An intense, fatal heat wave swept through the United States in July. More than 100 million people were under heat alert, and over 85% of the country had temperatures at or above Шаблон:Convert. This extreme heat severely intensified drought conditions. The heat wave was responsible for at least 19 deaths, including 12 in Maricopa County, Arizona.

Another heat wave moved across the United States in early August, with 80 million Americans under heat alerts.

The US Bureau of Reclamation said in June that those in the Colorado River Basin would have to create plans to reduce water usage. By the August 15 deadline, the mandate was not being followed and the federal government did not have plans to follow up. Also in August, the US federal government announced that Arizona, Nevada, and Mexico would have to reduce water usage, per a previously negotiated agreement. These cuts were much less than those prescribed by the Bureau of Reclamation.

A record-breaking heat wave shattered records across the Eastern United States on 5–7 November. On 7 November, several places set monthly high temperature records.

South America

Southern Cone

From 10 to 16 January, the Southern Cone had a severe heat wave.
