Last year, the Earth experienced a global climate crisis

2011 will go down in history as the year of extreme weather events, scientists say.

The National Oceanic and Atmospheric Administration of the United States in conjunction with the American Meteorological Society published a report on the state of the climate in 2011. Document developed 348 scientists in 48 countries, it contains detailed information about the climatic changes observed over the last year.

Climatic phenomenon La Niña, which is characterized by an abnormal cooling of the surface water in the central and eastern part of the tropical Pacific Ocean, has influenced many significant weather events in the world last year, says a leading scientist at the National Oceanic and Atmospheric Administration of the United States Kathryn Sullivan. Among them, the drought in East Africa, the southern United States and northern Mexico, the tropical cyclone season in the North Atlantic, typhoons in the northwestern Pacific, the strongest in 70 years floods in Thailand, Brazil, and a flood in the summer heat in the Central Europe.

The report also notes that the Arctic continues to show the most rapid climate change compared to the rest of the planet. It led to a warming of the fact that sea ice shrank to year low.

For the report to determine changes and general trends in the global climate system was used 43 indicators, of which the temperature in the upper and lower layers of the atmosphere, the assessment of cloud cover, sea surface temperature, and others.Source:
