It'll be a scorching week with no relief in sight. The heat waves ten to fifteen years from now will be much worse than this. And in 20 years or so they might not be survivable. How long does Las Vegas have? Water critical and their drought might be the new normal. Welcome to the shithole that humans have made of Planet Earth. It will only get worse.
Of course, some people might opt to commit suicide on Mars or the Moon. Gee, there are easier and cheaper ways to do it... multi-planet species? It won't happen. The earth might be a nasty shithole in the future, but it'll still be better than a stone dead frozen wasteland bathed in deadly radiation.
