Arctic freeze and snow wreak havoc across the planet

Arctic air and record snow falls gripped the northern hemisphere yesterday, inflicting hardship and havoc from China, across Russia to Western Europe and over the US plains.
There were few precedents for the global sweep of extreme cold and ice that killed dozens in India, paralysed life in Beijing and threatened the Florida orange crop. Chicagoans sheltered from a potentially killer freeze, Paris endured sunny Siberian cold, Italy dug itself out of snowdrifts and Poland counted at least 13 deaths in record low temperatures of about minus 25C (-13F).
The heaviest snow yesterday hit northeastern Asia, which is suffering its worst winter weather for 60 years. More than 25 centimetres (10in) of snow covered Seoul, the South Korean capital — the heaviest fall since records began in 1937.
In China, Beijing and the nearby port city of Tianjin had the deepest snow since 1951, with falls of up to 8in and temperatures of minus 10C. In the far north of China, the temperature fell to minus 32C. More than two million Beijing and Tianjin pupils were sent home and 1,200 flights were delayed or cancelled at Beijing's international airport.
The same far-eastern weather system took its toll of Sakhalin, the Russian island off Siberia, which was hit by blizzards and avalanches. Farther west, in northern and eastern India, more than 60 people, mainly homeless, died of exposure. Thousands of schools were closed. In Uttar Pradesh, the state neighbouring Nepal, the authorities spent Ł1.3 million on blankets and firewood for needy households.
Western Russia suffered a deep freeze as snow swept across the Baltic and north-central Europe, leaving the worst devastation in Poland, where 13 people died, bringing the toll from the cold this winter to 122.
Up to ten skiers died or were missing in avalanches. The worst incident was in the Diemtig Valley in Switzerland on Sunday, when avalanches hit a group of skiers and then the rescuers who went to their aid. Eight people were pulled from the snow alive, but four died, including an emergency doctor, and three more were missing.
In Italy, emergency services struggled with rare cold and ice. Motorways in the northeast were closed and military helicopters were sent to Sicily with medical aid.
In the United States, heavy snow fell again on the northeast.
In Burlington, Vermont, a record 33in of snow fell in a weekend storm. The previous record in a three-day period was set in 1969. Residents of the Northern Plains were warned to expect lethally cold temperatures of about minus 30C. [Colder than Moscow! We have only had minus 25C so far this winter...]
The icy conditions of Western Europe, which broke records in half a dozen countries in December, are expected to last for at least another week.
Guo Hu, the head of the Beijing Meteorological Bureau, linked this week's conditions to unusual atmospheric patterns caused by global warming.
Meteorologists were also trying to find a pattern in the heavy rains that have hit equatorial regions and the southern hemisphere in the past week.
At least 20 people have been killed in flash floods in Kenya after torrential rains made thousands homeless.
In Australia, the authorities declared a natural disaster along the Castlereagh River as it peaked after torrential rain, forcing 1,200 residents to abandon their homes for high ground.
In Brazil, the death toll from flooding and mudslides over the past four days rose above 80.
Closer to home, forecasters have warned Britons to brace themselves for a freezing cold, bleak new year — this winter is set to be the coldest for more than 30 years.
The Times Online reports that there's probably more to come.

There's probably more to come
The big freeze seems to defy all the logic of a warming world, but this is just part and parcel of the wild fluctuations in weather that can happen naturally.
Much of the blame for the wave of cold enveloping North America, Europe and Asia lies in the North Atlantic. An unusual layer of cold water has developed over the ocean, cooling the air and leading to a blockage in the weather pattern, with a huge area of high pressure centred around Greenland and low pressure towards the sub-tropical Azores islands.
Like a seesaw rocking backwards and forwards, these two vast pressure systems can swing from one extreme to another, creating havoc to winter weather in a phenomenon known as the North Atlantic Oscillation.
With pressure unusually high in the north, the oscillation is currently extremely negative, leaving much of the Northern hemisphere shivering in an Arctic blast.
The negative NAO has also shunted the jet stream, — powerful winds several miles up in the atmosphere, — much farther south than usual, steering much milder and wetter weather with it and leaving northern regions colder.
Even regions far from the Atlantic, such as China and Korea, are being hit by the freak cold weather. "The recent anomalies look very similar to the typical pattern of a negative North Atlantic Oscillation, with cold conditions in a band right across Eurasia and into the Korean region," said Adam Scaife of the seasonal forecasting group at the Met Office's Hadley Centre.
It is unclear why the North Atlantic seas are so cold and if, or when, the weather blockages will be shifted this winter.
The prospects for northern Europe look particularly bleak as a growing El Nińo in the Pacific, an unusual warming of tropical seas towards South America, is expected to bring further cold conditions later in the winter.
My reaction: The entire northern hemisphere is gripped by abnormally cold weather. This is just a continuation of the freakish weather seen globally over the last year: record heat, record cold, record rainfall, record snowfall, record hail, record drought, record locus infestation, etc... Yet, despite these unprecedented natural disasters around the world, the USDA persists in predicting record harvests. It is an insult to common sense.
