I'd think that reduction in albedo effect from the capture of solar power is a more important thing.
It seems that the reduction in albedo (the action of reflecting solar radiation back into space) has deteriorated to the point of no return.
Already the albedo is changing beacuse the big polar glaciers are melting.
All the radiation properties that can be summed up under the general term albedo can wildly vary according to the evolution of literally thousands of parameters all interacting with each other .
The word albedo refers to the percentage of light an object reflects.
Once the Earth is completely covered with ice, too, the ice won't melt on its own, because the Earth's reflectivity -- "albedo" -- is now so high.
In the language of climate science, we would increase by a few percent the Earth's "albedo" -- the ratio of incoming sunlight reflected back into space relative to the total inbound from the sun.
What you are referring to is called the albedo of the surface, and changes have a major impact on climate and warming.
The bias originates from underestimates of surface albedo, which is a critical parameter for accurately estimating surface UV irradiance in the Arctic.
The purified state is known as albedo, or whiteness.
