We can infer from the passage that the cooling effect of aerosols ----.
Smoke is clouding our view of global warming,
protecting the planet from perhaps three-quarters of
the greenhouse effect. That might sound like good
news, but experts say that, as the cover diminishes
in coming decades, we're in for a dramatic escalation
of warming that could be two or even three times as
great as official best guesses. This was the dramatic
conclusion reached last week at a workshop in
Berlin. Scientists have suspected for a decade that
aerosols of smoke and other particles from burning
rainforest, crop waste and fossil fuels are blocking
sunlight and counteracting the warming effect of
carbon dioxide emissions. Until now, they reckoned
that aerosols reduced greenhouse warming by
perhaps a quarter, cutting increases by 0.2°C. So the
0.6°C of warming over the past century would have
been 0.8°C without aerosols. But the Berlin
workshop concluded that the real figure is even
higher -aerosols may have reduced global warming
by as much as three-quarters cutting increases by
1.8°C. If so, the good news is that aerosols have
prevented the world getting almost two degrees
warmer than it is now. But the bad news is that the
climate system is much more sensitive to
greenhouse gases than previously guessed. In fact,
warming could go up by 7 to10°C.
