Europe's deadliest heat wave on record is killing thousands, and the same heat is now heading to the US — bad news for people, farmers, and food prices.

• France alone has seen over a thousand extra deaths, from heat and from people drowning while trying to cool off.
• Records fell across the UK, France, and Spain, with red alerts in Germany, Italy, and more — heat this extreme would have been near impossible 50 years ago.
• Most of Europe has little air conditioning (around 20% of homes), so people are taping foil to windows to block the sun.
• The same heat dome is hitting the US this week, threatening World Cup games and July 4th crowds.
• A new La Niña cycle points to more heat, drought, and crop failures ahead, which can push food prices up worldwide.

Outlook: Expect more record heat, extreme weather, and rising food costs this year, with the US bracing for a dangerous week.
