Absolute BS.
Bad math, no science. He's cherry picking data and extrapolating using partial worst case scenarios rather than actual measurements...that is not science, it's misleading propaganda.
The cost of moving away from fossil fuels is easily offset completely by the savings of the new technologies used, and likely the switch would be a gain to GDP, as it makes tens of thousands of new technology jobs and billions-trillions in additional GDP selling the tech, and once built many new techs have far lower operation costs, saving money. (That's how economies work, you sell stuff and make money...right?) It sure worked for my solar system, which you, Trance, would likely still try to talk people out of, claiming it's more expensive than it's worth, while reality is it paid for itself in less than 1/3 of it's expected lifespan AND has other benefits.
The cost of 'adapting to climate change' is infinite, as it's impossible. Plants, animals, and biota can't survive it...and people like to eat. Kind of hard to adapt if there's no food, far LESS farmable land, less or no natural food sources, etc.
Also, he ignores the facts that 1) it's almost certainly going to be MORE than 3 deg. by 2100 and 2)methane hydrates are already melting, and methane is (I think) something like 100 times more damaging to the atmosphere (as far as greenhouse effects), so even "just" 3 deg. suddenly becomes 8 deg...that's often ignored.
3 deg. means on average, but also means the spread gets larger. Winters are colder, summers are even hotter. 3 deg. doesn't sound like much by itself, but it really means 15-20 deg. hotter when it's hot, and 12-17deg. colder when it's cold.
