Three days ago, it was revealed that Stephen Harper was joining George W. Bush in a North American death wish by withdrawing from the Kyoto process.
Yesterday, NASA scientists announced that 2005 had topped 1998 as the hottest year on record. In fact, one NASA researcher said it was likely that 2005 may have been the warmest in several thousand years. While the rest of the world scrambles to patch together the barest beginnings of a survival strategy, it seems clear that the alternative path blazed by the US and Australia, a followed by India, China and now Canada is becoming the non-stop route to climate hell.
2005 Was Warmest Year on Record - NASA
Planetark.org, Jan. 25, 2006
WASHINGTON - Last year was the warmest recorded on Earth's surface, and it was unusually hot in the Arctic, US space agency NASA said on Tuesday.
All five of the hottest years since modern record-keeping began in the 1890s occurred within the last decade, according to analysis by NASA's Goddard Institute for Space Studies.
In descending order, the years with the highest global average annual temperatures were 2005, 1998, 2002, 2003 and 2004, NASA said in a statement.
“It's fair to say that it probably is the warmest since we have modern meteorological records,” said Drew Shindell of the NASA institute in New York City.
“Using indirect measurements that go back farther, I think it's even fair to say that it's the warmest in the last several thousand years.”
Some researchers had expected 1998 would be the hottest year on record, notably because a strong El Nino – a warm-water pattern in the eastern Pacific – boosted global temperatures.
But Shindell said last year was slightly warmer than 1998, even without any extraordinary weather pattern. Temperatures in the Arctic were unusually warm in 2005, NASA said.
“That very anomalously warm year (1998) has become the norm,” Shindell said in a telephone interview.
“The rate of warming has been so rapid that this temperature that we only got when we had a real strong El Nino now has become something that we've gotten without any unusual worldwide weather disturbance.”
Over the past 30 years, Earth has warmed by 1.08 degrees F (0.6 degrees C), NASA said. Over the past 100 years, it has warmed by 1.44 degrees F (0.8 degrees C).
Shindell, in line with the view held by most scientists, attributed the rise to emissions of greenhouse gases such as carbon dioxide, methane and ozone, with the burning of fossil fuels being the primary source.
The 21st century could see global temperature increases of 6 to 10 degrees F (3 to 5 degrees C), Shindell said.
“That will really bring us up to the warmest temperatures the world has experienced probably in the last million years,” he said.
To understand whether the Earth is cooling or warming, scientists use data from weather stations on land, satellite measurements of sea surface temperature since 1982, and data from ships for earlier years.
