This year so far coolest for at least 5 years: WMO

August 20 05:18 pm

LONDON (Reuters) - The first half of 2008 was the coolest for at least five years, the World Meteorological Organisation (WMO) said on Wednesday.

The whole year will almost certainly be cooler than recent years, although temperatures remain above the historical average.

Global temperatures vary annually according to natural cycles. For example, they are driven by shifting ocean currents, and dips do not undermine the case that man-made greenhouse gas emissions are causing long-term global warming, climate scientists say.

Chillier weather this year is partly because of a global weather pattern called La Nina that follows a periodic warming effect called El Nino.

"We can expect with high probability this year will be cooler than the previous five years," said Omar Baddour, responsible for climate data and monitoring at the WMO.

"Definitely the La Nina should have had an effect, how much we cannot say."

"Up to July 2008, this year has been cooler than the previous five years at least. It still looks like it's warmer than average," added Baddour.

The global mean temperature to end-July was 0.28 degrees Celsius above the 1961-1990 average, the UK-based MetOffice Hadley Centre for climate change research said on Wednesday. That would make the first half of 2008 the coolest since 2000.

"Of course at the beginning of the year there was La Nina, and that would have had the effect of suppressing temperatures somewhat as well," Met Office meteorologist John Hammond said.

"But actually La Nina is showing signs of moving towards a more neutral state."

The weakening of the La Nina effect over the last few months could see the global mean temperature creep up again in the latter part of the year, he added.

The past decade ending in 2007 was the hottest since reliable records began around 1850, according to the WMO. World temperatures are about 0.74 Celsius (1.2 F) higher than a century ago.

The U.N. Intergovernmental Panel on Climate Change (IPCC), a group of hundreds of scientists, last year said global warming was "unequivocal" and that manmade greenhouse gas emissions were very likely part of the problem.

The WMO releases its final figures for global temperature and ranking for 2008 in December.

S Africa faces 'winter wonderland'; snow,
coldest September temps in recorded history...

Parts of KwaZulu-Natal were transformed into a "winter wonderland" after snowfalls blanketed several areas of the province.
Temperatures plummeted into the low teens, with residents of Kokstad and Giants Castle waking up to 0C.
Durban experienced its coldest September night in recorded history on Friday night.
Snowfalls were reported in Kokstad, Matatiele, Underberg, Mooi River, Bulwer, Himeville and Nottingham Road.
Several roads in the province were closed and people were advised not to go snow hunting, as they risked becoming stuck in traffic and not being able to keep themselves warm.

Parts of California see coldest temps since 1893...
Temperatures dropped to 31 degrees in the Ukiah Valley on Saturday night and early Sunday morning, the coldest Oct. 12 morning since record keeping began in Ukiah in 1893, said Troy Nicolini, a meteorologist with the National Weather Service in Eureka. The previous record was 34 degrees in 1916.

Cold temps in Oregon break 118-year-old record...
Weekend cold set new record lows
Pendleton breaks 118-year-old record
The East Oregonian
Cold temperatures set several new record lows this weekend, including a low of 22 Saturday in downtown Pendleton that broke a 118 year-old record of 24.
Record lows started falling Thursday with a new low of 20 for Meacham, four degrees cooler than the previous record from 2006, according to information from the Web site for the National Weather Service Forecast Office in Pendleton.
Heppner and Long Creek then set new low temperatures Friday. Heppner hit 29, the coldest that date has seen since 1960 when it was 30; and Long Creek was 21, besting the 1987 record by four degrees.

Alaska glaciers grew this year, thanks to colder weather...
Two hundred years of glacial shrinkage in Alaska, and then came the winter and summer of 2007-2008.
Unusually large amounts of winter snow were followed by unusually chill temperatures in June, July and August.
"In mid-June, I was surprised to see snow still at sea level in Prince William Sound," said U.S. Geological Survey glaciologist Bruce Molnia. "On the Juneau Icefield, there was still 20 feet of new snow on the surface of the Taku Glacier in late July. At Bering Glacier, a landslide I am studying, located at about 1,500 feet elevation, did not become snow free until early August.
"In general, the weather this summer was the worst I have seen in at least 20 years."
Never before in the history of a research project dating back to 1946 had the Juneau Icefield witnessed the kind of snow buildup that came this year. It was similar on a lot of other glaciers too.
"It's been a long time on most glaciers where they've actually had positive mass balance," Molnia said.
That's the way a scientist says the glaciers got thicker in the middle.

Welcome to winter ... well, a taste of it, at least.
The coldest air of the season, with temperatures at mid-January levels, has blanketed the Carolinas. Near-record daytime temperatures are expected today in Charlotte, and snow is falling in the mountains

Snow in London, freezing Florida

do these events show that people should always be ready both for warm as well as cool weather because different types of weather keep on switching just like they always did?

The answer to this question is definitely "Yes".



In the very same way, one can perform a statistical analysis of the global mean temperature in the last 15 years. The result is that there has been no statistically significant warming

One would need a much higher signal-to-noise ratio for the signal to become not only measurable but also relevant for the practical life of the mankind.

Do these apparently ordinary snowstorms imply that the weather in 2050 won't be warmer than today? No. But do they imply that it will be warmer? Once again, no.

Yes, all these data show that every person who thinks that "global warming" is a real, urgent, and serious problem qualitatively affecting generic nations or generic people is an idiot
