This is the thing that always drives me up the fucking wall when people say it's too expensive to fix. Expensive compared to what? It's like saying it's not worth stopping your car driving off the cliff because it will take energy to hit the brakes or move the steering wheel, just totally ignoring the fact that there is a huge cost to doing nothing.
Anyway, sorry for the rant but this whole issue is insane.
I've posted this a few times because it says a lot about the priorities of America. We have the money, we just don't have the political power to get that money to do what it needs to do.
Because you can very easily already calculate the increased cost of natural disasters; droughts, floods, severe storms with wind and hail damage, crop spoilage, etc that is occurring right now. The future disasters will be worse.
As explained in the article they take the cost of current disasters and multiply the known effects of global warming to calculate what costs will be. They can only calculate what they know.
The costs are probably more like 1000x anyway because there is no way to really apply an accounting system to a complete calamity that would happen if numerous very likely feedback loops happen, as they hint to in the article.
No you cant, anyone telling you its easy to guestimate such a thing is ignorant or lying. Do you see the issue with people motivated by ideology making studies that show things that the conclusion will be in their favor?
