Fascinating tidbit:> A helicopter will not come when it’s above 120 degrees outside.Heat directly affects flight. Hot air is less dense and provides less lift. It's kinda obvious in retrospect, but I had no clue!<a href="https://www.backpacker.com/news-and-events/news/in-some-national-parks-its-literally-too-hot-for-helicopters-to-fly/" rel="nofollow">https://www.backpacker.com/news-and-events/news/in-some-nati...</a>

Here's a question for those of you with an investment mindset:The past two years have shown that we're more likely than not heading towards a climate collapse.I see no serious reaction from the markets, which seem to be assuming a business-as-usual scenario economically.I find this extremely difficult to believe and I don't see people publicly talking about a future with dramatically higher food insecurity and just a higher baseline cost for existing.What's the deal? Just collective denial?

I thought the hottest place on the planet was the Lut Desert. <a href="https://whc.unesco.org/en/list/1505/" rel="nofollow">https://whc.unesco.org/en/list/1505/</a>

The hottest place on Earth is cracking from the stress of extreme heat
