Warming caused by burning coal in a power plant can be felt in the atmosphere within 95 days — the time it takes for the emissions released from the plant to trap enough heat to exceed the amount generated from the plant itself, according to the study.

They show unequivocally that the carbon dioxide being added to the atmosphere is characterized by oxidized ancient plants, i.e., coal and oil.

As this happens, we would probably want a global fleet of aircraft that spray sulfate particles into the lower atmosphere to make up for the loss of aerosols once produced by coal plants.
