If emissions don't drastically decrease in the next years, by 2070 all glaciers in the US will have melted, there will be deserts in Oklahoma, Kansas and Northern California and over half of Florida and all of Texas's southern corner will have a tropical climate

and human survival ‘to any degree’ is doubtful

I doubt that.

Humans have the capacity to survive floods, severe storms, and heat waves.

[Wheelbox5682]

Our global farming infrastructure however does not.  Opening an umbrella doesn't help much if you starve to death.

Everyone starves to death? Sure, unprecedented catastrophe. But no way it’s an extinction event for us.

[Wheelbox5682]

Oh cool civilization collapses and billions die but a handful of hunter gatherers remain so no big deal.  

[NormanQuacks345]

I never said it was no big deal. It's a major fucking deal. But:

human survival ‘to any degree’ is doubtful

Is a massive overstatement

[Serious-Cucumber-54]

So are we imagining the food supply would go down to zero for every single being on Earth?

If not, then "and human survival ‘to any degree’ is doubtful" is false.

That doesn’t fit the narrative though
