Let’s take them at their word. It’s manmade and irreversible. The world will heat up and heat up until it reaches its next equilibrium.
What does the geo-historical record say? The earth was once much hotter and with more CO2 than today.
We’ll need more air conditioning and since global warming is inevitable no matter what, then let’s use all our coal up for electrical power first.
Carpe diem. Never mind coal. Start burning untreated garbage and human feces.
