Planet's sensitivity to greenhouse gases will determine how
much shading could be needed to slow temperature rise
An increasing number of scientists are studying ways to
temporarily reduce the amount of sunlight reaching the earth to potentially
stave off some of the worst effects of climate change. Because these sunlight
reduction methods would only temporarily reduce temperatures, do nothing for
the health of the oceans and affect different regions unevenly, researchers do
not see it as a permanent fix. Most theoretical studies have examined this
strategy by itself, in the absence of looking at simultaneous attempts to
reduce emissions.
