My biggest problem with global warming is that it looks like a scam aimed at the average Joe. It's like they try to guilt trip the western populations and tax them even more. It doesn't help that the "solutions" are contradictory as fuck
>stop driving cars
>but buy a new car every 3 years!
>consume less electricity
>but green energy is the future!
>be mindful of carbon emissions
>consume more frivoulous garbage!
>stop having kids kids are bad for climate!
>but you have to import uneducated 3rd world savages
And the best one yet is that globalism is pushed as this thing that brings everyone together and makes us all one nation meanwhile it's probably the worst thing possible when it comes to carbon emissions: mass consumption, overproduction of trash goods, imports from the other side of the world, planes everywhere, mining, oil drilling and exchanging. Then you have the guys that push for it, rich elites that don't give a fuck, owning yachts, sports cars, private jets, private drivers, they don't give a single fuck about their carbon emissions.
The final piece of the puzzle is scientists, they can't get their story straight, I remember back in the 90s they were terrorizing people with stories of how in 15 years the world as we know it would end if nothing is done, fast forward 15 years and..nothing, rince and repeat, "in 15 years it's the end of the world!", fast forward to 2018 and it's "this time in 15 years we all dead, trust us bro, we're scientists!". I can't even blame them it's so fucked up, if you have the "wrong theory" about climate change you get treated like a parriah and get your funding cut.
So yeah, climate change or not, it's really hard to make such predictions considering how big of an impact the sun has. Does human activity has an effect? Maybe, probably. Is it necessarly the worst thing ever? Again, that's up to debate. If only this wasn't a massively political topic maybe there could be serious research and debate done on the subject.
