The cost of not doing anything because we believe DT and those like him, is that we have to find another planet to live on, I wonder how much that will cost? I'd guess magnitudes on top of magnitudes above anything that the "libtards" are gonna cost you by investing in renewable energy.
Leaving the planet isn't a matter of cost, it's a matter of it being physically impossible given not only modern tech but we currently know of physics. Again, we do invest in renewable energy. The question is, how much more do you think we should be investing?
And yes, many deny science before he is POTUS, but he is the leader of the folks who deny, so he is a good example of who some trust with their scientific "facts" other than actual science.
Are you under the impression that DT has changed the way people think about climate change? He hasn't changed anyone's minds, he's pretty much a reflection of what people already believe If the Democrats, had someone impeached Trump, what do you think would have happened to what people believe about climate change? The answer is, absolutely nothing.
When I went to my Doctor, he said there's a 95% probability that I'll die within 5 years if I don't stop smoking. Some dude with a microphone and podium told me that doctor's are libtards, so I keep smoking, I mean the chances that the doctor, who has spent much of his life studying and practicing his field is actually right only means that I die before turning 50, so it's worth it!
Except that we've actually witnessed people die from complications related to smoking. The devastation you're claiming will come due to pollution isn't something anybody's ever witnessed before. And even if climate does change, we won't know whether it occurred because of human intervention or the earth's natural cycle. Trying to equate something we've witnessed to a prediction no one has ever seen before is rather weak arguement.
Oh, I forgot to say, because of the dire outcome (death) I decided to seek the opinion of 10,000 other doctors. 97% of them agreed with my doctor's prognosis, but I still believe the guy with the microphone and the podium, cuz..."libtards".
Except none of those Drs have actually seen the outcome you're claiming. And no, you didn't talk to 10,000 doctors, the media told you 10,000 think this. Of those 10,000, some of them aren't sure, but we'll count them anyway. And many of those haven't done the research themselves, they're just going with the crowd. And many of them aren't going to dare disagree since it puts their funding at risk.
Again, what are you claiming needs to be done, other than a vague 'more'? Are you in the AOC camp where the world will end in 10 years if we don't pass her green new deal? We should just give our money to other countries through the Paris Accords? Maybe something in between? Should you be forced to give up your Raptor? What do you want?
