NASA was studying other planetary systems, and, especially the earth with satellites. It was NASA scientists who sent up the first warnings that the oceans were warming at very quickly (in geologic time) and that atmospheric CO2 was also increasing (IIRC). So, big win for scientific research. Not much of a win for ever conflicted human beings. 25 years of disinformation from the large OIL companies really set up back and sowed seeds of doubt that continue to this day. The problem isn't scientific research, it's self interested corporations and powerful individuals who wage war against that research. I believe humanity will put an end to climate change, it'll just take much longer than it should have and cost far, far more than it should have in lives, property and global financial stability. God bless our grandchildren.
