It's really hard to calibrate satellite measurements.
And although they do a brilliant job of it, I think the thing that really convinces people that those measurements are true is that we have a completely different set of measurements that back it up, which is
Most of the energy that's absorbed by the Earth is absorbed by the oceans.
And since about 2000, the world's had a really rather good, I think, under-remarked way of measuring the heat content of the oceans.
And this is a set of little boys called Argo.
They float along at a certain depth and they change their depth and they record the temperature and the salinity and various other things.
And they come up to the surface and they send a message to a satellite saying, here's what this bit of the ocean looks like.
And there are thousands of these things doing this on a regular basis.
And this means we have a much better picture of how the temperature of the ocean is different at different depths and how that's changing over time.
And it turns out that what they call the heat content of the ocean is changing very much in step with the energy imbalance as measured by the satellites.
Different nations have done different things about air pollution, but recently, particularly China, has got very serious about it.
And in the actions that followed on from the 2012 Olympics, the amount of sulphur emitted in China has plunged quite dramatically.
The International Maritime Organization spent a lot of the 2010s
planning ways to reduce the amount of sulfur emitted by cargo ships.
Those rules came in in 2020 and there's a measurable effect of reduced reflectivity as a result of those rules.
The IMO had no institutional way of thinking about the fact that it was also slightly warming up the earth.
I don't think that's in itself culpable.
I do feel somewhat though that they should have thought about developing that capacity and they really didn't think about that very much.
Well, there are two ways.
One is we can reduce the amount of greenhouse gas warming.
