OK, looking at the timst4's other comments, I see the phrase "... before wet bulb temperatures reach 50C". So I'll believe that 50C in the post I replied to is not meant to be an increase, but a level. But it seems that "wet bulb" got omitted here. That explains the illogic of saying we'll soon see 50C when that has occurred at numerous times and places in the past. 50C web bulb temperatures would much more unusual. (I'm not sure if they've ever occurred or not.) But there's no reason to think people are going to commonly experience 50C wet bulb temperatures. That's far beyond anything predicted by conventional science.
