Extreme temperatures across the United States are grounding emergency helicopters.

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.

    This is cope. I know too many people who roleplay as environmentalists, but are fully engaged in consumerism. Friends who look at me funny when I insist that we can have the same conversations over discord that we can when I drive an hour to to see them or who think that Biden’s Green Deal will be enough. My primary concern for the past 30 years, more time then I’ve been an adult, has been to reduce my co2 output or make sure that what co2 I do output has been productive. There’s a huge disconnect between myself and my supposedly like minded friends that can only be explained my a deep unwillingness to be put in any sort of discomfort. So they cope by telling themselves that they deserve this vacation that requires air travel or ignore the mountain of waste that the average movie production produces or that plastic recycling works and you can drink your Pepsi™ if you just put the bottle in the recycling.

    If the rich are responsible for all of our problems, we’re responsible for letting them be rich.
