Global Warming and Energy Implications: Will Nature Soon Cool Hot Debates?

Energy Tribune

Measurements by four major temperature tracking outlets reported that world temperatures dropped by about 0.65° C to 0.75° C during 2007, the fastest temperature changes ever recorded (either up or down). The cooling approached the total of all warming that occurred over the past 100 years, which is commonly estimated at about 1° C. Antarctic sea ice expanded by about 1 million square kilometers – more than the 28-year average since altimeter satellite monitoring began.

But have these collective announcements ended the global warming debates? No, stay tuned for further developments.

Cyclical, abrupt, and dramatic global and regional temperature fluctuations have occurred in observable patterns over millions of years, long before humans invented agriculture, capitalism, smokestacks, and carbon trading schemes. To appreciate just how lucky we are to live in the present, consider climate cycles from a historical perspective. Over the past 400,000 years, much of the Northern Hemisphere has been covered by ice up to three miles thick, at regular intervals lasting about 100,000 years each. Very brief interglacial cycles lasting about 12,000 to 18,000 years, like our current one, have offered reprieves from the bitter cold. From this perspective, there can be no doubt that current temperatures are abnormally warm.
