A team of scientists from Australia and US has found a solution for a challenging problem in climate research. Climate models predicted more greenhouse gases would weaken the equatorial Pacific trade winds.However, over the past two decades, observations showed this Walker circulation was getting stronger, accelerating sea level rise in the western Pacific, and consequent changes in global climate.The researcher team reports, “The answer to the puzzle is that recent rapid Atlantic Ocean warming has affected climate in the Pacific”.Their study, “Recent Walker circulation strengthening and Pacific cooling amplified by Atlantic warming”, was published on Sunday in Nature Climate Change.

While previous research supposed natural variability alone accounted for cooling in the eastern Pacific, this study highlights a previously overlooked climate feedback: as the Atlantic warms, it alters the winds over the Pacific, depressing the ocean temperature there.As coauthor Shayne McGregor of the University of New South Wales explains, “the main cause of the Pacific wind, temperature, and sea level trends over the past 20 years lies in the Atlantic Ocean […] We saw that the rapid Atlantic surface warming observed since the early 1990s, induced partly by greenhouse gases, has generated unusually low sea level pressure over the tropical Atlantic. This, in turn, produces an upward motion of the overlying air parcels. These parcels move westward aloft and then sink again in the eastern equatorial Pacific, where their sinking creates a high pressure system. The resulting Atlantic–Pacific pressure difference strengthens the Pacific trade winds.”

Coauthor Malte Stuecker of the University of Hawaii Meteorology Department reports that “Our study documents that some of the largest tropical and subtropical climate trends of the past 20 years are all linked: Strengthening of the Pacific trade winds, acceleration of sea level rise [three times faster than the global average] in the western Pacific, eastern Pacific surface cooling, the global warming hiatus, and even the massive droughts in California”. His colleague cauthor Fei-Fei Jin adds, “We are just starting to grasp the scope of the impacts of this global atmospheric reorganization and of the out-of phase temperature trends in the Atlantic and Pacific regions”.Work earlier this year by coauthor Matthew England, University of New South Wales, showed the stronger winds have churned up the waters of the Western Pacific Ocean, so more heat flows from the winds into the water. This appears to explain why global surface temperatures have recently risen more slowly.

Coauthor Axel Timmermann of the University of Hawaii notes a further amplifying effect: “Stronger trade winds in the equatorial Pacific also increase the upwelling of cold waters to the surface. The resulting near-surface cooling in the eastern Pacific amplifies the Atlantic–Pacific pressure seesaw, thus further intensifying the trade winds […] It turns out that the current generation of climate models underestimates the extent of the Atlantic–Pacific coupling, which means that they cannot properly capture the observed eastern Pacific cooling, which has contributed significantly to the leveling off, or the hiatus, in global warming.”As Professor England said, “It will be difficult to predict when the Pacific cooling trend and its contribution to the global hiatus in surface temperatures will come to an end. […] However, a large El Niño event is one candidate that has the potential to drive the system back to a more synchronized Atlantic/Pacific warming situation.”

Early afternoon saw a shooting in the church parking lot of New Life Church, an Evangelical Megachurch, in Colorado Springs, Colorado, United States. According to a report quoting the church’s pastor four people were shot by a gunman in the car park.

At this time it is unknown if there is any connection with yesterday’s shooting approximately 70 miles away in Arvada, Colorado, where a gunman shot two and injured two people at Faith Bible Chapel’s missionary training centre in a dormitory.

Strong storms hit the southeastern United States on Friday. Crews are currently working to restore power to the area. There are two known fatalities. Tornadoes were reported in South Carolina, Mississippi and Louisiana.

In South Carolina, a tornado piled up cars, injuring 15, by an elementary school.

In Mississippi, 9 people were injured with “8 to 10 homes destroyed,” said Ben Dudley, Kemper County’s emergency management director.

In Alabama, a few mobile homes were destroyed and power was out.

Louisiana had the worst damage (especially around Iberia Parish) with a tornado touching down.

In Georgia, there were a large number of trees down.

Since the August 20 release of Abdelbaset Ali Mohmed Al Megrahi, who was convicted of planting a bomb on Pan Am Flight 103, there has been growing controversy surrounding the events which led to his release. Pan Am Flight 103 exploded in-flight in 1988 as the aircraft flew over Lockerbie, Scotland, killing all 259 people on board and eleven more on the ground. Al Megrahi is the only person to have been convicted of the bombing.

In recent years, the British government has negotiated oil development deals with Libya. As part of the negotiations, at least three UK ministers traveled to Libya in the months leading up to Al Megrahi’s release.

Leaked letters from UK Justice Secretary Jack Straw to his Scottish counterpart, Kenny MacAskill, stated that it was in the “overwhelming national interests” of the UK to include Al Megrahi in prisoner transfer agreements which were part of the oil trade deals. These letters have lead to widespread speculation that the British government influenced the Scottish decision to release Al Megrahi.

Al Megrahi was released on compassionate grounds as he was diagnosed with terminal cancer. However, this diagnosis was called into question as The Times revealed that the health director of the Scottish Prison Service, Dr. Andrew Fraser, relied on the advice of a general practitioner instead of an oncologist, when issuing his recommendation for release.

When Al Megrahi returned to Libyan soil, Libyan leader Muammar al-Gaddafi thanked Gordon Brown and Queen Elizabeth for his release.

Saif al-Islam Muammar al-Gaddafi, the son of Muammar al-Gaddafi, has stated that during the prisoner transfer agreement (PTA) phase the trade negotiations, the Al Megrahi case was not specifically named, yet it was implied.

“The fight to get the [prisoner transfer] agreement lasted a long time and was very political, but I want to make clear that we didn’t mention Mr Megrahi. At all times we talked about the PTA. It was obvious we were talking about him. We all knew that was what we were talking about,” he said.

In Scotland, the release of Al Megrahi has caused significant debate. A poll conducted for the BBC by ICM Research found that 60% of Scots thought the Scottish Government was wrong to allow the release. 68% believe the decision was made fore reasons that did not pertain to Al Megrahi’s health.

“No one I think seriously believes we made any other decision except for the right reasons,” First Minister Alex Salmond said on Wednesday. “I think it was the right decision. I also absolutely know it was for the right reasons.”

“We didn’t think that the Lockerbie decision should be linked to trade or oil decisions by anyone who looked at the coincidence that the prisoner transfer agreement was being negotiated at the same time as commercial contracts,” Salmon also stated.

The UK Prime Minister’s office stated Monday that, “There was no deal over [the] release of al-Megrahi nor could there ever be, since all decisions were for the Scottish, not U.K. government.”

“The central assertion in this story is completely untrue and deeply misleading,” Downing Street added.

Correspondence released on Tuesday by the UK government shows that Abdulati Alobidi, the Libyan minister to Europe warned of “catastrophic effects for the relationship between Libya and the UK,” if Al Megrahi were to die in prison in Scotland.

When Salmond asked Straw what the national interests of the UK were, Jack Straw replied, “Having sponsored terrorist attacks in the past, it [Libya] is now an important partner in the fight against terrorism.” Libya approved a large oil exploration contract to BP within days of the letter.

Libyan officials have said that since al-Megrahi’s return to Libya, his health has deteriorated. He was not part of the 40th anniversary celebrations for Gaddafi’s coup d’état held on Tuesday.

West Indies have beaten England by 15 runs in the first Twenty20 international of their tour of England at The Oval, London, England.

The West Indian innings started off badly by losing Gayle early, however they turned their fortunes around with some attacking and aggressive cricket and posted a huge total of 208. A bigger total could have been posted if it had not been for a late innings batting collapse. England started their reply by getting off to a flyer, but lost some early wickets that slowed down the run-rate. Leading the charge was Paul Collingwood with a fast 79 with 5 4’s and 4 6’s. In the end, England fell short by 15 runs. Had they not have lost the early wickets, England would have probably won the match to take a 1-0 lead in the series. Instead, it is West Indies that have taken a 1-0 lead in the series.

Global stock markets fell steeply on Thursday on investor concerns about the growing sovereign debts of European Union member states Greece, Portugal, and Spain. A report of a rise in weekly jobless claims in the United States contributed to the market gloom. The MSCI World index fell the most in over nine months. Currency and commodities markets also posted major moves.

The euro fell more than one percent against the US dollar to an eight-month low; against the yen it fell 2.2%, approaching a one-year low. The price of crude oil fell 5% to US$73.14 per barrel and gold slid 4.4% to US$1,063 per ounce.

Greece’s Prime Minister, George Papandreou, announced an austerity program, but that is now threatened by plans by the largest trade union for a national strike. In 2009, Greece’s budget deficit was 12.7% of the nation’s gross domestic product (GDP). Papandreou’s plan called for that to drop to 3% by 2012.

Gary Jenkins of Evolution Securities told the Financial Times, “[t]he risk aversion trade is back on as the debt problems of Europe are for the first time bringing down global markets. Corporate earnings may come in strongly [in the US], but investors are more concerned about the possible default of a sovereign European nation.”

“This is a sovereign problem, and it’s hitting everything,” said Keith Springer of Capital Financial Advisory Services to Reuters. “If other European countries are having trouble like Greece, then it’s a big problem for banks, and the banks are the foundation for everything. European banks will be in trouble and that will carry over to all stocks.”

“The focus is shifting toward Spain and Portugal, where the deficit-reduction plans have been far less ambitious than Greece,” said Kornelius Purps of UniCredit Markets & Investment Banking to Bloomberg.

Concerns in Portugal centered on political tension surrounding a regional spending bill. In Spain, the source of worry was reportedly because the government backed down from promised pension reform.

European Central Bank President Jean-Claude Trichet sought to ease investor fears, in part by noting that the deficit in the US is expected to hit 10% of GDP in 2010, compared with about 6% in the eurozone. He said that he was “confident” that Greece is moving in the right direction.

Trichet did admit that it is of “paramount importance” for Greece, Portugal and Spain to get their public finances under control.

Ikeda Kanako, a 21-year-old senior student of the Meiji Gakuin University and the first daughter of celebrity surgeon Yuko Ikeda, was kidnapped at about 1225 (UTC+9), June 26, 2006, in Shibuya, Tokyo.

A bullet was fired and one officer slightly cut when police stormed a Kawasaki apartment to rescue the girl.

Kanako was dressed in a white light half-sleeved cardigan, blue jeans with a bistre belt made of leather, a spring green camisole and carried a bag of Vuitton when she was abducted at a bus stop.

She was found unharmed 13 hours later by Japanese police at a condominium located in Nakahara-ku, Kawasaki, Kanagawa. The young woman’s make-up was not disordered; Kanako’s long brown fringe was not disheveled at all and she was wearing what she had been when she was kidnapped.

The kidnapping of Kanako was a big story in Japanese media in June, 2006. The story appeared in many newspapers as the front-page news on June 27, 2006.

Kanako and her kidnappers had been in touch with her mother using Kanako’s mobile phone. The effort to free her was helped greatly by a woman who witnessed the moment Kanako was taken; she wrote down the license plate of the van and other details.

Police traced mobile phone calls and were able to locate the van in Kawasaki where they detained two of the kidnappers as they went shopping.

One conspirator Li Yong, 29, from China, led the policemen to the apartment and tricked Kaneo Ito, 49, from Japan, to open the door. Ito managed to discharge one bullet before being restrained by an assistant police inspector, the first man in the room.

The other man involved in the kidnap of Kanako was Choi Gi Ho, 54, from South Korea. Kanato was freed unharmed.

The Tokyo Metropolitan Police Department arrested three men on suspicion of conspiring to kidnap a woman and hold her to a reported 300 million yen ransom.
