Now where did I leave my woollen mittens?
December 1 2008
Professor Emeritus Don J. Easterbrook warns of global cooling:
Global warming (i.e, the warming since 1977) is over. The minute increase of
anthropogenic CO2 in the atmosphere (0.008%) was not the cause of the
warming-it was a continuation of natural cycles that occurred over the past
500 years.
The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually
assuring us of about 30 years of global cooling, perhaps much deeper than
the global cooling from about 1945 to 1977. Just how much cooler the global
climate will be during this cool cycle is uncertain.
Recent solar changes suggest that it could be fairly severe, perhaps more
like the 1880 to 1915 cool cycle than the more moderate 1945-1977 cool
cycle. A more drastic cooling, similar to that during the Dalton and Maunder
minimums, could plunge the Earth into another Little Ice Age, but only time
will tell if that is likely.
UPDATE
No need to tell Perth:
Perth has experienced its wettest and coldest November in 17 years.
The city saw more than 57ml fall over the month, the seventh wettest on
record.
UPDATE 2
No, hoots Tim Blair.
It's actually the coldest Perth November in 37 years.
Boy, do I feel like a Tim Flannery.

Methinks you'll have to wait until the year 2038 to make that claim.
See ya back here in 30 years.

NASA reports 2008 is ninth warmest year since 1880 -
By Renee Schoof, McClatchy Newspapers Renee Schoof, Mcclatchy Newspapers -
Tue Dec 16, 6:04 pm ETWASHINGTON - The year 2008 was the ninth
warmest year since instrumental temperature measurements began in 1880, and
all
of the nine warmest years have occurred in the past 11 years, NASA reported
on
Tuesday.
The new data from NASA's Goddard Institute for Space Studies and other
government agencies on Tuesday adds to the evidence scientists have been
observing about a warming Earth as fossil fuel burning emits heat-trapping
gases
into the atmosphere.
NASA also reported that the January to November global temperature was 0.76
degrees Fahrenheit above the average for the 20th Century.
NASA also noted that the past year was cooler than any since 2000.
Scientists
note that global warming is a steady trend, but within it there are natural
variations.
The NASA report noted that "Eurasia, the Arctic and the Antarctic Peninsula
were
exceptionally warm, while much of the Pacific Ocean was cooler than the
long-term average." It said the relatively cooler temperature in the
tropical
Pacific was due to a La Nina, the cool phase of a natural temperature
variation.
Britain's Met Office on Tuesday also said that La Nina was part of the
reason
2008 was slightly cooler than earlier years this decade. By Britain's
accounting, 2008 was the 10th warmest year on record dating back to 1850,
and
all 10 of the warmest years occurred since 1997.
"Human influence, particularly emission of greenhouse gases, has greatly
increased the chance of having such warm years," said Peter Stott of the Met
Office in a statement Tuesday.
The Met Office also reported that global temperatures from 2000 to 2008 are
nearly 0.36 degrees Fahrenheit higher than the average for 1990 to 1999.
The National Oceanic and Atmospheric Administration on Tuesday summarized
these
and other trends, including:
- The 2008 Atlantic hurricane season was the third costliest, after 2005 and
2004.
- The U.S. had nearly 1,700 tornadoes from January through November, which
ranks
second behind 2004 for the most tornadoes in a year since records began in
1953.
- Arctic sea ice in 2008 reached its second lowest level at the end of the
melting season in September, following a record low in 2007. In 2008, the
ice
shrank to 1.74 million square miles, which was 0.86 million square miles
below
the average annual minimum from 1979 to 2000.
Sea ice loss is important because ice reflects most of the sun's radiation,
but
open ocean water absorbs most of it, adding to the warming trend both in the
ocean and on land.
