The last decade has been the warmest since records began in the world. According to data from the World Meteorological Organization (WMO) released in Bali, in line with the XIII Conference of the Parties to the Climate Change Convention, which comprises 192 countries, the global average temperature has been so far this year 0.41 º C above average during the thirties between 1960 and 1990, which was 14 º C.
Another remarkable fact of this year has been the enormous loss of Arctic sea ice, which was one million sq km less than the previous record in 2005. As stated by the director of WMO, Michel Jarraud, the effect has been so "dramatic" for the first in history has been ice-free Northwest Passage, which could navigate between the Atlantic and North Pacific American continent.
Fortunately there is a positive development in extreme weather events alarm reported WHO: The ozone hole over the South Pole has been "relatively" small compared to the highs seen between 2000 and 2006, whose record was 29 million square kilometers.
However, the WHO cites as "atypical" that the La Nina phenomenon in the Pacific remains still present later this year, leading to abnormal temperatures in parts of the world's largest ocean, affecting coastal human activities and fishing.
2007 has been plagued by very devastating floods, droughts, deep and large storms and hurricanes in many regions of the planet. The data provided by WMO from offices weather of the 188 countries comprising the UN agency ete. To these are added the data recorded by satellites and the special collaboration of two prestigious institutions such as the Hadley Centre in the UK, and Oceanic and Atmospheric Agency in the U.S.. Cyclones and hurricanes
The floods have affected this year to Mozambique, the countries of Central Africa, Bolivia, Indonesia and northern Europe, where there have been hundreds of deaths.
cyclones and hurricanes have remained on average figures, which does not mean that there have been thousands of deaths in its path on the ground in the countries most affected by these violent events. One of the cyclones, Sirdar, in Bangladesh caused over 3,000 deaths in the month of November.
droughts particularly affected in 2007 to North America, Australia and China, where more than 40 million hectares of crops have been damaged and tens of millions of people have suffered water shortages. WMO emphasizes the extreme temperatures in the various regions of the world. January was the warmest month compared with the average of the three decades between 1961 and 1990, with an average temperature of 12.7 º C.
There have been two heat waves that hit southern Europe in June and July when temperatures were registered in Bulgaria up to 45 º C, and broke incedios huge in Greece.
By contrast, in Argentina were recorded during the austral winter minimum temperatures very low, up to -22 º C and snow fell in many parts of the country, where there had been snow in the last seven decades. Michel Jarraud
linked some of these events to climate change is occurring and noted the fourth report of Intergovernmental Panel on Climate Change, which urges the international community to reduce greenhouse emissions.
