The doom and gloom predictions have always been about slow but inexorable changes in the climate. Not that suddenly a mega hurricane is going to rip Florida out of the ground and toss it into the ocean, but that weather is going to get worse and more extreme, that sea levels will rise, and more and more places will gradually become uninhabitable as conditions get worse. There won't be single things that you can point to and say "that one was global warming", it's about trends that are harmful for us in the long term. If you eat a chocolate bar's worth more calories than you burn every day, it sounds like doom and gloom to say you'll gain 200 pounds if you don't change anything, and you won't be able to point to any one meal as something to be concerned about because that's not really out of the ordinary for a day... but slowly and steadily, you'll gain weight, and if nothing changes you will get there eventually.

And even though you aren't owed dramatic destruction, and shouldn't require it to believe the thousands of people who study this as their life's work and all agree that things are dire and not getting better fast enough... you've literally just lived through the hottest twenty or so days in recorded history. Is that a coincidence, do you think?
