Let's assume for the sake of discussion that $73 billion in annual burdens is accurate. How much do you think it would cost to walk the planet back from a barren wasteland in 2300? - given you even had a population to do it.

Currency collapse, famine, disease, wars, anarchy - all world wide, "Mad Max Beyond Thunderdome".

Don't confuse global averages with the actual extremes happening around the planet.
Sure .2 deg seems like nothing, it's the new highs and lows affecting large regions you need to focus on.

It's 60F in CA, 40F in NY, average is 50F.
It's 120F in CA, -20F in NY, average is still 50F, good luck trying to get comfortable in either.
