Earlier quoted context omitted.
Another reason: the evidence is worldwide and obvious. Siberia melting in a couple of years, which it hasn't done in 40,000 years. All the glaciers receding drastically. The Antarctic ice shelf undergoing irreversible melting. It doesn't take a century of temperature measurement to see the result of heating up.
Did a scientist tell you this? That is not how science works. You cannot attribute events around you to some notion of obviousness. That reasoning would not pass any physicist's approval. Climate science is predicated upon a proper understanding of physics. Any scientist who tells you that worldwide evidence is obvious should be treated with the same level of respect as Dr. Oz. The typical response would be that the…
Re: 2015 “smashed” 2014’s global temperature record
#251I'm not sure what you're getting at. The earth is heating up, we know, because all the ice is melting. And that hasn't happened for hundreds of centuries - long before people were a significant actor on this globe. What is in dispute? The cause, sure. That's still very much an interesting subject. But the fact of the earth heating up is, yes, obvious.
