«
While low
clouds have a predominantly cooling effect due to their shading of sunlight, most
cirrus clouds have a net warming effect on the Earth,» Spencer said.
The iris hypothesis and the tropical upper tropospheric water vapor and
cirrus cloud feedbacks,
while arguably still open to debate, are not by any stretch of the imagination a major driver in global climate feedback.
So, lots of cumulus
clouds and few
cirrus clouds cool the earth
while lots of
cirrus clouds and fewer cumulus
clouds warm the earth.
Regarding
clouds, recent trends suggest a slight decline in total
cloud cover over several decades, due to a reduction in low
clouds, which exert a net cooling influence,
while high
cirrus clouds, which are net warmers, have remained relatively constant.
