I think climate denial will look pretty funny in hindsight after agriculture has broadly collapsed leading to mass famines, and a bunch of coastal cities are several meters under toxified saltwater.
Like, that thing I just described is the optimistic scenario, where humanity/society survives despite things turning way shittier. It could be much worse.
That's really not even close to the optimistic scenario. It's arguably not even in the pessimistic scenario if you're not just in the "make stuff up club."
We're talking at most half a meter of rise by 2050, at most 2 meters by 2100, at most 4 meters by 2150. The intermediate projection is a third of a meter by 2050. The optimistic projection (which we're not going to hit) is 3/20th of a meter.
Climate change is real. The risk of famine is real. The risk of global conflict is real. The risk of trying storms is real. However, "doomsday everybody dies" is not really on any serious projections. The worst case is "a lot of people in a lot of poor nations die and rich nations have more wars and more immigration."
Yeah - really confusing. I worked it out as (c.) 6 inches and then further confused myself as to why I was thinking inches from metres. Wild. Luckily I’ve lived with both metric and imperial and am apparently bilingual.
That is not accurate, and doomerism only helps those who want us too demoralized to put up a fight. If you want to be part of the solution to climate change, I recommend doing some reading on what the range of projections and outcomes actually look like.
