Most trees alive today won’t survive in the climate expected 40 years from now

Worrying news. There's a YouTuber - CodysLab (relevent video: https://m.youtube.com/watch?v=sghWcjGYSxY) - I watch that experienced this exact die-back with pinion-pines.

It's interesting to see how a marginal increase in temperature can have huge impacts on the ecosystem, for example incests able to survive where previously they couldn't.

I'd also be interested to see what the impact of a large number of tree's dying out would cause - growing up deforestation of the rainforest was a huge environmental issue (and continues to be).

> At the current pace of warming, much of the world will be inhospitable to forests as we know them within decades. The extinction of some tree species by direct or indirect action of drought and high temperatures is certain. And some recent research suggests that, in 40 years, none of the trees alive today will be able to survive the projected climate.

That is so ridiculous. Temperatures within 40 years aren't going to change by much more than they've already changed over the past 100 years. Did most forests die off and vanish? No, in fact the extra C02 in the atmosphere, and warmer climate is beneficial for tree growth - if only we weren't clearing the forests we'd have more trees today. The earth has been hotter than where we're headed with global warming. It was heavily forested at that time. To be extra clear, none of that is saying global warming isn't a huge problem, just that forests dying off probably isn't the part to worry about.

Articles like this do climate science a serious disservice and give people reason to doubt climate change - they're counter productive.
