This
is a seminal work which discusses the effects of reducing visible
pollution while not addressing greenhouse gases.
Note,
we are already seeing large areas where methane hydrates are being
released into the atmosphere.
Global
Dimming
Since
measurements began in the 1950s, scientists have discovered that
there has been a decline of sunlight reaching the Earth; they called
it global dimming.
But
according to a paper published in the journal of Science, the dimming
did not continue into the 1990s and indeed since the 1980s scientists
have observed a widespread brightening.
What
caused the dimming to go down and what effect will it have, if any,
on climate change?
The
film explores the theory that pollution is shielding the oceans from
the full power of the Sun, and disrupting the pattern of the world-s
rainfall.
There
is evidence that dimming caused the droughts in sub-Saharan Africa
which claimed hundreds of thousands of lives in the 1970s and 1980s.
It
reveals that we may have grossly underestimated the speed at which
our climate is changing.
At
its heart is a deadly new phenomenon. One that until very recently
scientists refused to believe even existed.
Alarmingly,
the dimming continues today, and Asia, home to half the world-s
population is currently under threat.
