Six motorcyclists rode into Death Valley National Park on July 6. Only five came out alive. With temperatures reaching 128 degrees Fahrenheit in California, the cyclists faced extreme heat exposure that killed one and sent another to a local hospital, according to the National Park Service.

When there’s a medical emergency like this, helicopters are typically dispatched to get people to a hospital. However, the extreme heat made it impossible for the helicopters to fly.

The next day, an emergency helicopter pilot in Stanford, California had to cancel a flight because the tarmac near a patient was too hot for him to land. As reported by The Washington Post on Wednesday, the pilot said he’d never seen temperatures this bad in his 27-year career.

Extreme heat, as many across the U.S. are experiencing this summer, can cause computer and mechanical systems on board helicopters to overheat and malfunction. But it’s not just a mechanical issue as air pressure is also a factor. Air expands when it’s hot and contracts when it’s cold. As it gets hotter outside, air pressure plummets. The air literally gets thin which means that spinning helicopter blades have less air to cut through and it’s harder for them to achieve lift. That makes it dangerous, and sometimes impossible, to fly.

I'm saying your being manipulated into inaction.

We're locked in for between 4-10C of warming at this point, with the highest probability being ~6C. Even 4 is catastrophic for global food production.
