So, to be clear, you guys are denying the world is getting warmer and is causing things like rapid ice melt? Or just the causes of it?
Or you just don't really care about the causes and "think" everything is just going to be hunky-dory?
FSD... 1 degree celcius will have massive changes but we could probably survive it as a species and society. However when you talk about +4 degrees... the world as we know it will be a dramatically different place. The southwest and great plains will nearly be uninhabitable (due to drought and extreme temperatures), coastal cities will be flooded by rising seas and battered by extreme storms. The overall global weather will be extreme due to dramatic changes in oceans temperatures and thus current patterns. Fish stocks will plummet impacting a huge percentage of the population worldwide that depend on the sea for their food (and economy).
The good news is we can mitigate and lessen the rise in global temperatures by changes to our processes, behaviors, laws, economies, and infrastructure. But it has to be now and it has to be serious. There isn't time to mess around with weening off (ensuring continued profits for established industries) or slow transitions. It needs to be quick, decisive, and widespread.
Otherwise...
Then again, you don't really care about everyone else, right?
Lotta certitude going up in here. It's funny how liberals are so certain of something so complex. But when you ask them for any specificity it always boils down to "Didn't you hear what I said? It's gonna be BAD! 4 degrees! Dogs and cats living together! Mass hysteria!"
Ice caps expand and contract. Artic ice is down. Antarctic ice is UP. For liberals it doesn't really matter - it's all evidence of manmade climate change (as opposed to just climate change, which has been happening since the earth was formed 6000 years ago).
I predict it's going to be cold this winter, and that is definitive prove that manmade global warming is a sham.
A lot to unpack there.
First, nothing is 100% certain... But scientists that study these things can make projections and hypothesizes, which, in my mind, we should heed bearing in mind the consequences. Moreover though, you are asking for something that is impossible to predict with absolutes. And just because we don't have the capabilities to make things black or white with the science we have today doesn't mean that we should allow for business as usual, burying our heads in the sand.
Second, given the predictions, there isn't time or forgiveness to wait and see whether they come true. Just because it snows in the winter or is cold doesn't mean that the larger global climate isn't changing in a myriad of ways we greatly contribute to. The global climate has been changing since its existence... Just not at this rapidly accelerating pace.
Currently, we have 7.5 billion people on the planet with production and infrastructure to support it based on 19th and 20th century technologies and consumption patterns. We need to quickly start to model the transition to a sustainable and renewable economy and society so that the rest of the world, developing and otherwise can follow suit.
