Full extended quote: by Dr. Neil deGrasse Tyson:
"As I have said before, when a consensus of experiments emerges, the good thing about science is that its true whether or not you believe in it.
Climate change has taken on political dimensions. It has taken on cultural and social dimensions, and that's odd because I don't see people choosing sides over E = mc2 or other fundamental facts of science.
But, the experimental consensus is there that humans beings by virtue of our conduct, burning sources of carbon, fossil fuels among them, that have been buried for millions of years. We burned the carbon that was deep underground and now it is in the atmosphere...That makes carbon dioxide, which is a greenhouse gas is warming the earth.
We're warming (the planet) and that comes with consequences.
By the way, Earth will survive this. People say, 'Save the Earth.' No, don't worry about Earth. Earth will be here long after we render ourselves extinct.
What happens is that we are changing the climate faster than our culture may be able to respond. The consequences is that you melt icecaps, (and) the water levels rise. Not inches, not feet, but tens of feet. And that will begin to flood coastlines."
Some of the most important cities in the world were built on coastlines for the very reasons that is how you accomplish trade. That is what made those ports successful. So, the very foundation of our civilization requires coastlines that existed at a time when there was not global climate change, the kind that would be warming the Earth.
So, get ready for that. It is going to redraw the maps of the world, unless we do something about it.
Venus suffers from a runaway greenhouse effect. It is 900 degrees on Venus, not because it is simply closer to the sun than us. It is not that much closer. It is a little bit closer. It's got nearly 100% CO2 in its atmosphere and its atmosphere is 100 times more dense than ours. So heat comes in and it does not come out and the temperature rises.
I don't want Earth to look like Venus."
