The United States is bracing for chaotic weather this week, with the South set to experience another heat wave following a short respite from searing temperatures earlier this month. The National Weather Service expects some areas to reach temperatures so high they’ll hit new daily records.

And it’s not just the U.S. Across the Northern Hemisphere, in Europe and Asia, extreme temperatures are causing deadly heatstroke and early wildfires ahead of the start of the astronomical summer on Thursday.

Here’s what’s happening related to extreme weather and the climate right now:

— From extreme heat to unseasonable cold in the Pacific Northwest, the U.S. is facing a myriad of extremes. The Rocky Mountains may get a late bout of snow, while further south, firefighters in Los Angeles are dealing with their first major fire of the season and Phoenix will experience more days above 110 degrees Fahrenheit (43 degrees Celsius).

— With temperatures of up to 116 degrees Fahrenheit (47 degrees Celsius) in Mecca, Saudi Arabia, on Sunday, at least 14 pilgrims marking the start of Eid al-Adha died of heatstroke, according to Jordan’s state-run Petra news agency. An Associated Press reporter saw several of the more than 1.8 million pilgrims collapse due to burning heat.

— Record temperatures on the Mediterranean island of Cyprus led to at least two heat-related deaths, state officials say. And over 3.2 square kilometers (1.2 square miles) of forest were scorched near the capital of Nicosia. The country has been experiencing temperatures of 104 degrees Fahrenheit (40 degrees Celsius) and higher over the past week.

— For those preparing for extreme temperatures over the next few days, Tammy Weber’s guide to surviving the searing sun recommends plenty of water, loose clothing and getting into air conditioning, whether in your own home or in public spaces that would be able to provide it.

— And finally, the European Union on Monday approved a long-awaited plan to better protect nature in the bloc, known as the Nature Restoration Law. The issue saw months of protests by farmers but survived a razor-thin vote by lawmakers. It’s part of the EU’s European Green Deal to have the world’s most ambitious climate and biodiversity targets.
