Chilling end to global warming forecast
By Richard Macey
March 11, 2004

Global warming could disrupt the world's sea currents, sending Europe into a chill within 100 years and devastating tropical ocean life, a CSIRO scientist says.

Richard Matear, a Hobart-based marine researcher, said the oxygen content of deep ocean water between Australia and Antarctica had fallen 3 per cent since 1968.

If new research confirmed the decline was happening throughout the world's southern oceans, it would be a strong sign global warming was interfering with sea currents.

According to NASA "the thawing of sea ice covering the Arctic could disturb or even halt large currents in the Atlantic Ocean.

"Without the vast heat these currents deliver - comparable to the power generation of a million nuclear power plants - Europe's average temperature would likely drop 5 to 10 degrees."

While North America would not be as severely hit, the space agency said "such a dip in temperature would be similar to global average temperatures toward the end of the last ice age roughly 20,000 years ago"...

On May 18th, 2003 a post started out:
I think calling it 'global warming' is a mistake, people in cooler climates just think, 'hey, that'd be nice'. It's increasing the energy put into the system:
the Highs get higher,
the Lows get lower,
the Drys get drier,
the Winds get blowier,
and whole systems that are balanced get tipped, and who knows which way they'll go?

Sudden Climate Change?
"When 'climate change' is referred to in the press, it normally means greenhouse warming, which, it is predicted, will cause flooding, severe windstorms, and killer heat waves. But warming could also lead, paradoxically, to abrupt and drastic cooling:

Ocean & Climate Change Institute: Abrupt Climate Change
Most of the studies and debates on potential climate change have focused on the ongoing buildup of industrial greenhouse gases in the atmosphere and a gradual increase in global temperatures. But recent and rapidly advancing evidence demonstrates that Earth’s climate repeatedly has shifted dramatically and in time spans as short as a decade. And abrupt climate change may be more likely in the future.
