Solar geoengineering

A lot about climate solutions, regenerative agriculture, carbon markets, solutions like carbon capture.

There were a few on solar radiation management or sunlight reflection methods, which we will talk about in a little bit.

On and on and on.

It's also held in conjunction with the UN General Assembly.

So it ends up cooling the Earth quite substantially.

And we're currently cooling the Earth by half to one degree, which means if we stopped all fossil fuel emissions tomorrow, the temperature a couple of weeks later would shoot up by half to one degree.

so and we saw this uh leon simons our co-host here is one of the world's experts on how the the shipping rules change to lower sulfur content of shipping fuels have greatly accelerated climate change in the last five years so um anyway that's um that's what solar geoengineering is and it's also known by two other names sunlight reflection methods srm or solar radiation management srm I'll just call it SRM from now on.

But there was this SRM gathering called the Degrees Initiative.

OK, well, look, your fifth watch point was very specific.

You said, who says the word solar geoengineering? And Professor David Keith, surprise, surprise, has said them in New York.

And has SRM finally begun? begin solar radiation modification? Has it finally begun to move out of this specialist silo and into the more mainstream climate security discussion?

I think it is actually.

Looking forward to chatting.

so today it's going to be a little bit different uh chris and i met because we were debating on blue sky about uh solar geoengineering also known as sunlight reflection methods or solar radiation management or srm probably use solar geoengineering and srm today as referring to this and what that also means.

We're not going to go into the details.

There's many other programs on it, but basically it means artificially cooling the earth.

So this is just one example where the global models are potentially severely under predicting, but also because we're using the global models to downscale to the UK case, those deficiencies, perhaps not in the convection for individual storms, but certainly the larger scale circulation.

So the larger scale circulation that drives the weather and drives these extremes is, there's certainly issues with the representation in the global models.

So this is one thing that kind of, concerns me is like the models themselves and that this is something that concerns me with solar radiation management is that the models don't agree a lot of the time on even the change in rainfall some models might say that we expect it to get wet some models might say we expect to get drier at the same location which then
