However, an atmospheric greenhouse effect can significantly raise planetary temperatures.
But the formula for computing planetary temperatures is not simple.
I don't just mean recording planetary temperatures and pressures.
The proposal to create a Polar Sea as a means of moderating planetary temperatures.
This zone is fairly narrow, because constrained by the requirement that the average planetary temperature be consistent with water remaining liquid throughout the time required for complex life to evolve.
Transformation of the global carbon cycle in the next century is projected to raise planetary temperatures, lead to more extreme fluctuations in weather, alter species distributions, and increase extinction rates.
As the forest died and the ice advanced and the overall planetary temperature dropped, local temperatures dropped in some areas and rose in others.
Big coal, faced with mounting evidence that carbon dioxide emissions have contributed hugely to increases in planetary temperatures, resolutely decided to shoot the messengers.
The formula for computing planetary temperatures is not simple.
It may be possible to extract measurements of snowfall from these data for clues to changes in planetary temperatures.
