I'm not being silly. You're the one who gave very little detail, and no links, and stated that I looked for more data but got a forbidden messsage. I was just showing where you could get more information.
Your claim: This used to happen every ~100,000 years but with climate change this will be more common. also appears to be just personal opinion. The World Weather Attribution page says: We note that even with climate change, the prolonged heat was a very rare event expected to occur less than once every 130 years. One hundred and thirty years is somewhat less than your one hundred thousand years.
If you're going to invent figures, make them reasonable. If you're quoting someone else's figures, at least let us see where you got them.
