Sudden Climate Change: Just a Movie Plot?
The folks at the Why Files, always with a keen eye for the prevailing
winds, have whipped up another interesting overview of a currently hot
topic -- sudden climate change as depicted in "The Day After Tomorrow".
Gentle Subscribers who have been wondering if the movie is more science
fiction than science will find some interesting answers at today's site.
"Climate. Don't count on it... Seen The Day After Tomorrow? The new
adventure movie follows a posse of high-school super-nerds hounded by water
and ice. Maybe it's just the allure of seeing New York and Los Angeles
undergo on-screen obliteration, but the disaster film is burning up the box
office. ...It's scary: Global warming, caused by burning too much fossil
fuel, suddenly reverses circulation in the Atlantic Ocean, triggering
continent-wide storms and then an ice age. ... Is climate a steady
lumbering beast? Or does it go through 'bumps, jumps and wiggles'?" - from
the website
This Why Files feature looks at the scientific kernels in the movie and
relates them to science in the real world. With fascinating sidebars, vivid
photos and explanatory graphics, the presentation briefly explores the
impact of ocean currents on climate and how they could be disrupted through
polar ice cap melting. Along with a quick history of the last ice age,
18,000 years ago, are the implications drawn from polar ice core samples. A
select bibliography -- the "Misconceptions on abrupt climate change" is
particularly good -- rounds out the essay.
