Cooling or warming climate? 'Data says global cooling, physical model says it has to be warming'

When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, to show global temperature trends over the last 10,000 years, the University of Wisconsin-Madison's Zhengyu Liu knew that was going to be a problem.

"We have been building models and there are now robust contradictions," says Liu, a professor in the UW-Madison Center for Climatic Research. "Data from observation says global cooling. The physical model says it has to be warming."

Writing in the journal Proceedings of the National Academy of Sciences today, Liu and colleagues from Rutgers University, the National Center for Atmospheric Research, the Alfred Wegener Institute for Polar and Marine Research, the University of Hawaii, the University of Reading, the Chinese Academy of Sciences, and the University of Albany describe a consistent global warming trend over the course of the Holocene, our current geological epoch, counter to a study published last year that described a period of global cooling before human influence.

Extreme weather in Russia - July 2014 (VIDEO)

Extreme weather phenomena battered many parts of Russia in July. From waterspouts in the Black and Azov Seas, to super-sized hail on beaches, super-cells in Siberia, and deluges throughout the country, Russia is not used to such weather. Check it out...

Record antarctic cold threatened lives of British Antarctic Survey members during power outage

Thirteen members of the British Antarctic Survey (BAS) were trapped and in danger of freezing to death when their base, Halley VI, lost power. Power went down on July 30th and is now partially restored. The BAS waited to report the incident until power came back up, however now reports that the incident was so serious that all science activities have been suspended and emergency contingency plans to abandon some of Halley's eight modules and attempt to shelter in a remaining few have been prepared.

The incident is particularly serious, as the station is likely completely cut off from rescue for months.

The incident occurred during the height of the Antarctic winter while southern sea ice is at or near record highs (Marc Morano has details at Climate Depot).

One Survey member, Anthony Lister, managed to send a out a "tweet" when power came back up, reporting that the outage occurred while the station was experiencing record cold temperatures of -55.4° C (-67.72° F). (h/t Rai news)

The summer of 2014 has been one of the mildest on the books - and could be the first summer in a decade without a heatwave.

"It wasn't clear if it was going to be a hot or a cool summer," said National Weather Service meteorologist David Stark. "We started out the year very cool and it seems like we just continued that. It doesn't look like we have any heat waves in the near future."

Instead of searching for the skimpiest outfits to battle the sizzling sun, New Yorkers are reaching for their sweatshirts.

"It's been so much colder this summer," said Susan Vartholomatos, 51, who broke out her bikini for a beach day Friday afternoon. "In the morning, when I go out to my terrace, I need a sweatshirt."

Vartholomatos said she wishes it was hotter, adding "I'd take heat and humidity over snow any day."

Only four days have hit 90 degrees this summer, three in July and one in August, with the hottest temperature on the books clocking in at 91.

Golf ball-sized hail struck suddenly in Airdrie, north of Calgary, Thursday afternoon.

Airdrie hail storm likely caused 'gustnado' in Calgary, officials say

Environment Canada says incident was not a tornado but rather a spout from an Airdrie storm


It's a bird, it's a plane, it's a - "gustnado?"While police say they did receive several reports of a tornado touching down east of Métis Trail and north of Stoney Trail, Environment Canada says the incident was rather a gustnado, or spout from a nearby storm system battering Airdrie.

The weather agency says the storm system was not over Calgary at the time of the incident and the spiral winds likely came from the nearby storm.Det. Dale Seddon with the Calgary Police Service says the incident didn't cause any damage and hit a grassy area.

Another violent hailstorm hits the Altai region, Russia

Image
Another hailstorm abruptly started in the Altai region a day ago. Hundreds of cars and buildings suffered, even the walls of buildings got holes, as the hailstorm was accompanied by stormy weather with high wind speeds.

Here we have almost fifty photos of the hailstorm's aftermath and the posts from the discussions boards. Here is one:

"Those are Americans testing meteorological weapons. Soon you'll see this in Moscow. Every day." - said one person.

"They have disturbed an ancient mummy in Altai, maybe they should put it back", says another. They really did.

Renmark had a frosty start with the mercury dipping well below zero.
Adelaide has woken to its coldest start to an August day in 126 years and it was colder across other parts of South Australia. At 6:30am (ACST) the temperature was down to 0.9 degrees Celsius. The weather bureau said it was the coldest August morning since 1888.

It was also the coldest day Adelaide has experienced in any month in six years. Senior forecaster Mark Anolak said the low temperature has been brought on by cold air from the Antarctic moving over Adelaide.

"Under a ridge of high pressure that we are experiencing at the moment, clear skies have led to very cold temperatures over the last couple of days," he said.

"Murray Bridge has had its coldest ever start to the day in August at -2.7 degrees this morning."

Most of regional South Australia woke to cold and frosty conditions. The weather bureau said it got down to -5.6C in Renmark, just above freezing in Lameroo and -3.9C in Loxton. Clear, sunny skies lifted the temperature as the morning went on.

Wild hail storm shocks residents in Southeast Wisconsin

Image
New Berlin-Wisconsinites pride themselves on being a hearty bunch, able to handle any kind of weather.

But the hail storm that happened Friday evening was like nothing many had ever seen before.

The CBS 58 Newsroom received several calls from viewers in shock.

CBS 58 viewer Joe James became a reporter of sorts and started rolling video and narrating the amazing sight outside his car window as he drove along Racine Avenue between Waukesha and Muskego.

"It was just 90 degrees earlier today," he declared. "Amazing hail storm."

Others in Ozaukee County said drivers pulled alongside the road they were so startled by the pounding of the hail stones.

Another resident in New Berlin said the hail had done major damage to her backyard, bringing down tree limbs everywhere she looked.

"You guys should be out here," she urged. "This is a big deal."

See for yourself.

Ontario County farmers suffer crop damage from extreme hailstorm

Image
It was a harsh wakeup call. People around our area were woken up by a strong thunderstorm. In some places, that storm dropped enough hail to cover the ground like snow. In addition to the hail, the storm brought heavy rain, lots of lightning and strong winds. Places in eastern Ontario County were among the hardest hit by the weather.

In his eighty years, Nicholas Legott had never seen a hailstorm in Geneva like he saw Thursday morning. He certainly did not expect to be shoveling hail out of his driveway.

Legott said, "The force of the hail hitting the house. It wasn't just that. It was coming down in buckets. It was unbelievable."

Just Wednesday, Legott and his family were ecstatic about how well their new garden of organic tomatoes and peppers were doing. Now, they are a shredded, icy mess.
