Global warming does not frighten me; I have spent a lot of time with the actual (raw) data. The physics is clear. CO2 is a greenhouse gas and will warm the planet. The coefficients and feedback loops are obscure. How much warming do we get, and how much does the planet resist change.
Geoengineering scares me to death. If we change the albedo (reflective coefficient) of our clouds, ice, or some other large portion of our planet, that will certainly change global temperatures. We know how large the initial change will be - opposite but equal in magnitude to the “warming disaster” we want to avert. For a sufficiently large remedial action, that could trigger a new path in global temperatures, an ice age. Geoengineering our way out of an ice age may not be as easy as triggering one.
>Global warming does not frighten me;
Global warming shouldn’t frighten anyone. A warmer climate is beneficial to life. Ice ages on the other hand? Death on a massive scale.
“The physics is clear. CO2 is a greenhouse gas and will warm the planet. The coefficients and feedback loops are obscure”
So the physics is “clear” but the coefficients are “obscure”???
But hey, it’s climate “science”.
