Regarding climate change, I’ve always thought of it as analogous as steroids in baseball; you’ve always had home runs and other outside variable factors (a wind gust coming through unexpectedly, a humid night, a scuff on the ball) impacting the flight of the ball, and steroids may take that warning track fly and push it over the wall, or the infield fly and make it a bloop, or a roided-up pitcher with too much velocity on a fastball and straightening it out, making it easier to hit the other way. .
