Winds and ocean currents slightly accelerated the Earths rotation

Sometimes it seems that the time goes faster. In November 2009, it was just that: a half days of the month decreased by 0.1 ms.

The speed of rotation of the Earth affect different factors. For example, if the winds are slowed down, the planet rotates faster to preserve angular momentum.

In November 2009, however, has played something else. The culprit turned out to the Antarctic Circumpolar Current, encircling the continent. Stephen Marcus and his colleagues at the NASA Jet Propulsion Laboratory (USA) and the Institute of Physics of the Earth (France) noted that on 8 November 2009, it has

In the near future the flood of the century may occur every three years

In August, Hurricane "Irene" swept through the Caribbean and the eastern United States, leaving a broad band of the ruins. Rearing them water rolled over the dam, flooding the coastal and inland areas. Many said it was the most devastating flood of the century.

However, researchers at the Massachusetts Institute of Technology and Princeton University (both — the U.S.) found that climate change will fall in such a storm to land more frequently — every 3-20 years. And floods that occur today, "every five centuries," will occur every 25-240 years.

So build embankments and dams higher, otherwise they will fill

Thailand declared a drought disaster area in 79 districts of 13 provinces

Nearly 80 districts in 13 provinces of Thailand are from Friday a disaster because of the drought which began in February, the department said in a statement warning of natural disasters the country.

Statement issued on Friday by all state media in the country.

Disaster zone are defined as areas in the provinces of Lampang, Lamphun, Nan, Phayao, Uttharadit, Kampheng Phet, Phitsanulok and Sukhothai in the north, Lei in the northeast, and Chachoengsao Chanthaburi in the east of Thailand and Suphan Buri and Phetchaburi in the center of the country.

Previously, the department has already announced a number of

Each year, due to the melting of glaciers the oceans increases by half a millimeter

Due to the melting of glaciers in the Arctic, the tropics and temperate sea level rises every year and a half a millimeter — to such conclusion the American scientists at the University of Colorado.

U.S. climate scientists examined data obtained from 2003 to 2010, relating to changes in the mass of ice outside of the Arctic. These data come from the climatological probes GRACE, launched from the Baikonur Plisetsk in 2002 for an accurate gravity map of the Earth. At present, these satellites are used by scientists to monitor climate change, including the state of the ice caps.

Earth lurch heralds great glaciation

Scientists are not the first debate about what mechanisms can dramatically change the Earth's climate. Many people talk about global warming due to emissions of CO2, others — the flares. Another theory concerned the displacement axis of rotation of the planet. And now, this version has been confirmed. It was found that even a small shift is enough to cause ice age in this century, writes the Daily Mail.

Harvard professor Peter Huibers, using computer models to design scenarios, proved that it is the slope of the Earth's axis is crucial. "At least now we can say with more

Why is winter in Ukraine have become shorter, but colder?

Because of global warming, winters have become shorter than 1-3 weeks. But in this case — no warmer!

We know after all that winter can not do without, but frost still hit unexpectedly. On the street cold, snow drifts, and it seems the end-edge in sight … The mark on the thermometer drops lower and lower, doctors and FEMA are alarmed, and students canceled classes.

What happens to the Ukrainian weather? We found out how long we still have to suffer and why the first long winter there, and then if you really come — it seems, is going to

Repeated drought in East Africa is inevitable

Picture of rainfall over East Africa changed so that severe droughts have become more likely, and this means that you need to review the principles of providing assistance to the region.

One of the poorest parts of the world have already experienced its worst drought in 60 years — in 2010-2011. In a report released last week, the organization Oxfam and "Save the Children" argue that the international community slow to help, and this has led to thousands of deaths that could have been avoided. Despite predictions of an impending drought, many donors are reluctant to act until the

Polar bears are under threat of extinction

The melting of Arctic sea ice from global warming in 2011 reached a record high, and threatens the polar bear population, according Hydrometeorological Center of Russia.

According to the melting of the polar research stations affected are the oldest and most thick sheets of ice, and the total mass of Arctic ice has decreased to 55% of the average of the 1980s and 1990s.

"Apart from the obvious problems associated with sea level rise, such melting carries another danger — the decline in the population of polar bears, because it depends on the

In the Arctic, discovered a giant pool of fresh water

British Geophysics told about the huge pool of fresh water, which they found in the western Arctic Ocean. If over time the flow ENTERED entire amount in the North Atlantic, Europe is waiting for a serious climate change, says BBC.

The growing accumulation of atypical for the ocean of fresh water has reached a volume of about 8000 cubic kilometers. Fueled by the circulation of the Beaufort, it is only since 2002 has risen above the sea level by 15 centimeters.

Researchers from University College London (University College London) said that strong wind swirled flow clockwise, causing

Population wintering in Russia tits fell by a third in 20 years

Ornithologists have noted a decline in almost a third of tits wintering in the European part of Russia, in the last 20 years, told RIA Novosti President Russian Bird Conservation Union (accompanied) Viktor Zubakin.

"The sharp decline in the numbers of several species of small insectivorous birds wintering forming Shinichi winter flocks observed in the winter 2010-2011. Rather, it was triggered by abnormal heat, fire and, as a consequence, the loss of insects — the main prey of birds. However, the overall downward trend population becoming apparent for many years, "- said Zubakin.

According to Sopra winter
