I came across an article the other day.
I remember seeing lots of banners held by climate protesters saying that “There is NO Plan B” so I’m sure they’ll be delighted that their fears are assuaged. They can all go home and watch SpongeBob or whatever they normally do.
I’m not too sure about the two proposals they are putting forward. Their main idea seems to be to cover the entire planet with a blanket of clouds. This, in their theory will effectively cut down on heat coming in from the sun.
Now I’m not a climate scientist. I tend to rely on logic and experience with a reasonable understanding of physics, and that’s what is giving me cause for concern.
My bedroom isn’t heated by choice [it does have a radiator but it’s permanently switched off]. I like a cool bed. Last night I got into bed and fairly quickly the bed warmed up as the quilt kept my body heat in. However, as the temperature outside was low my bed didn’t warm up enough. I threw a coat over the bed and almost immediately fell asleep as the temperature was now just right. The coat had acted as additional insulation to prevent heat loss.
Another example is obvious at this time of year. On cold clear nights, a frost forms. If however it’s cloudy frost doesn’t form as the clouds have prevented heat escaping and the temperature doesn’t drop far enough.
So what happens if the cover the entire planet with clouds? It may well cut down on the sun’s heat coming in but it will also insulate the planet against heat loss? I hope they throw that into their calculations before starting their experiments.
And what happens if their calculations are wrong? Suppose their geoengineering [sorry – “climate intervention”] goes tits up? Will they be able to suck up all the crap they have thrown into the atmosphere or the stratosphere? Will they be able to reverse whatever it is that they have done?
Or maybe their experiment will work and the radiation from the sun is drastically reduced, and then the sun sinks into its solar minimum reducing the radiation even further?
The Earth could end up like an iced lolly.
