There is a kind of heat that kills you even in the shade, even with all the water you can drink. Last week it parked on top of half the country. Here's how it works.
When the air gets hot enough and humid enough, sweat stops evaporating off your skin. Sweat is the only cooling system your body has. Once it fails, your core temperature just climbs until your organs quit. It's called wet bulb heat.
World Weather Attribution, the scientist consortium that does the rapid math on these events, measured last week as a once-in-200-years humid-heat extreme, and concluded a heatwave with these specific impacts would not have happened at all in a preindustrial climate.
They titled the report "Fossil Fuels Are Heating America's 250th Birthday."
The tally from one American week. Atlantic City hit 106 on the Fourth of July. New York and DC saw their hottest temperatures in over a decade. 180 million people sat under major or extreme heat risk. At least 25 deaths are being investigated as heat-related, 19 in New Jersey alone.
Hundreds of thousands lost power. Officials ordered environmental limits bypassed and emergency diesel generators fired up to stop cascading blackouts.
And the nights are the real killer. When overnight lows sit near 80, the body never resets. Chicago, 1995: that mechanism killed 739 people in five days.
We were still the lucky ones. Europe spent June counting bodies. Early estimates put the heatwave's toll between 15,000 and 25,000 dead. France alone lost roughly 2,700 people. Records fell in thirteen countries. A train derailed in Sweden because the heat warped the tracks.
Fifteen to twenty-five thousand dead is five to eight September 11ths, in one month, on one continent.
June in France ran hotter than the climate models projected. Reality is outrunning the math. This is not a heatwave anymore. This is the climate.
Now the part nobody in Washington will say out loud. The heat is coming for the food. Europe's record June scorched its corn and vegetable crops. Corn futures in Paris jumped to contract highs. Fertilizer prices are up 35 percent this year.
An estimated 363 million people are already at risk of acute hunger. And the World Bank warns the El Niño building in the Pacific could slash rice output 20 to 50 percent in affected regions. That is not doomer talk. That is the World Bank talking.
Washington's answer? Trump fired roughly 600 people from the National Weather Service. Forty percent of forecast offices were left short-staffed. Some offices go unstaffed all night now. Past day four, some forecasts now run with "little to no human intervention."

So take care of each other. Drink water before you feel thirsty. Cool the wrists and the back of the neck. Check on the people around you, especially the ones nobody else is checking on. Heat kills quietly, and mostly it kills the people no one is watching.
Exxon's own scientists predicted this warming with deadly accuracy in the 1970s. The industry buried the science and bought the politicians. Every tenth of a degree since was a boardroom decision.
A second heat dome is already building over the West. NOAA says this El Niño could become one of the strongest on record.
This summer is the warm-up act.
And it's only July.
