Is the sun causing global warming?
Is the sun causing global warming?
No. The sun can influence the Earth’s climate, but it isn’t
responsible for the warming trend we’ve seen over the past few decades.
The sun is a giver of life; it helps keep the planet warm enough for us
to survive. We know subtle changes in the Earth’s orbit around the sun
are responsible for the comings and goings of the ice ages. But the
warming we’ve seen over the last few decades is too rapid to be linked
to changes in Earth’s orbit, and too large to be caused by solar
activity. In fact, recently (2005-2010) the sun has become less active,
while temperatures have marched upwards.
One of the “smoking guns” that tells us the sun is not causing global
warming comes from looking at the amount of the sun’s energy that hits
the top of the atmosphere. Since 1978, scientists have been tracking
this using sensors on satellites and what they tell us is that there has
been no upward trend in the amount of the sun’s energy reaching Earth.
A second smoking gun is that if the sun were responsible for global
warming, we would expect to see warming throughout all layers of the
atmosphere, from the surface all the way up to the upper atmosphere
(stratosphere). But what we actually see is warming at the surface and
cooling in the stratosphere. This is consistent with the warming being
caused by a build-up of heat-trapping gases near the surface of the
Earth, and not by the sun getting “hotter.”
