If even institutions which purport to be the biggest purveyors of truth can't tell the truth about this, then what hope have we?
18:48
The work that I've been focusing on in the last few years deals very much with the flow of energy through the climate system.
18:56
This relates more directly to the main sources of human induced climate change.
19:04
Now, the reason for that is because the direct effects of humans are relatively small from space heating and electricity use.
19:12
And the main way in which humans change the climate is by interfering with the natural flows of energy through the climate system.
19:19
And so we have the sun beating down with a certain amount of radiation coming in.
19:23
Some of it's reflected.

Yes.

He's, um...
79:52
And one of the reasons he moved to Denmark was not just to get out of the way, but, uh, because he's a glaciologist and he works, uh, extensively in, in Greenland, and, uh, and he's, he's done a lot of work there.
80:03
I, I do not agree with, uh, his statement about that we're doomed by any means, though.
80:10
I mean, I mean, we're certainly headed in the direction where we're going to experience significant climate change, and exactly what magnitude that climate change will be is still somewhat in our hands, but we are going to experience some of it, and it will have some consequences.
80:26
Uh, you know, the, the way in which we often talk about this is that there are two, two parts to the overall solution.
80:33
One of them is so-called mitigation.

Methane, I think, is the, is the subject, methane in, uh, at the ocean floor.
2:05
For those of us who don't remember from high school earth science, what is an El Nino?
2:11
And El Nino refers to an exceptional warming of the central and eastern tropical Pacific Ocean.
2:19
El Nino can be thought of as a way of regulating the temperatures.
2:25
The reason is that the Pacific Ocean is huge in the tropics, and it extends more than a quarter of the way around the globe.
2:32
The sun is beating down.
2:34
It heats up the surface of the ocean.
2:36
But there are trade winds, easterly trade winds in the tropics and along the equator.

8 MINS LATER

10:14
And so in the short term, what does an El Nino year mean in terms of the global temperature that we see?
