There are thousands of scientists all over the world who study our climate and of course climate change. The overwhelming consensus is that humans play a significant role in global warming.

There are some people that want us to believe that the world isn’t warming right now, partly because the way we are measuring temperature is not right. For instance, some people argue that thermometers are mostly distributed in the northern hemisphere and there are not very many in the south, so while we’re thinking the earth is warming, we’re not actually sure it is. To me this seems like a crazy, far-fetched idea. It would imply that all those thousands of people measuring temperature around the world haven’t taken that into consideration and are deliberately ignoring this fact.
Whether the earth is actually warming or not, the glaciers are definitely disappearing. That even I can see with my amateur eye. Take any glacier picture from 10 years ago and from today, and you can see the difference pretty obviously, and it seems to be happening in the southern hemisphere, too. If it’s not temperature that’s melting the glaciers, what is?
CO2 in the atmosphere is now as high as it last was 800,000 years ago. People have argued with me: Well, there you have it – 800,000 years ago we had CO2 levels this high. The world is always changing, whether we’re in it or not.
Two points: The CO2 level took hundreds of thousands of years to go from lower levels to over 400 ppm, and then back down again. Our latest grand change took 50 years. That gives me pause.
Second point: 800,000 years ago, when we had CO2 levels of 400 ppm, the seas were 50 feet higher. Most of Manhattan would be under water, all of Miami, all of Boston, all of Los Angeles, and much of San Francisco, San Diego and Seattle.
The so-called climate deniers argue that somehow scientists are in a conspiracy. They are falsifying findings to make money.
So, thousands of the world’s climate scientists are conspiring and make stuff up to cause us to not buy fossil fuel for some weird reason. And the only saviors are an American president, a few dozen American senators, a few dozen American congressmen and about 10 oil companies?
I am not buying it.
