As to cooling the earth, well,
a tiny fraction of a degree maybe, and even then it would take a few hundred years.
Man's contribution to the effect is nearly nil, and to spend * trillions * of dollars to stop
a tiny fraction of a degree of climate change is beyond stupid.
Perhaps, but it does affect the measured global temperature rise, potentially making the measured rise slightly greater than it actually is, and in a world where
tiny fractions of a degree are significant...
Not exact matches
More CO2 would be better for both plants and animals, and any putative warming due to human emissions would be an extremely
tiny fraction of one
degree C.
Indeed, it is a
tiny fraction of the expense
of the Kyoto Protocol, for example, which is expected to shave off just a few tenths
of a
degree of temperature rise over the next hundred years.
