Heat Wave 2010: The Record of 2007 Beaten

Published 19th October 2010 - 0 comments - 703 views -

The year 2010 holds the overall record heat last hundred thirty (130) years. This emerges from a report by the American National Climatic Data Center who says that the year 2010, although ongoing, has already delighted the show from the 2007 year so far recognized as having most distraught thermometers.

According to the survey and analysis of the team of James Hansen at the Goddard Institute for Space Studies at NASA, the average temperature of the planet shows that the first six months of 2010 hold the record heat last hundred thirty (130) years. In fact, according to a report by the U.S National Climatic Data Center, the first five months of 2010, were warmer with heat waves ever recorded since the start of temperatures recording in 1880. “The temperature of the combined land and ocean from January to May showed 0.68 degrees Celsius above the average of the twentieth century”, said the Meteorological Institute. The months of March, April and even May in particular, recorded an average temperature of 0.73 degrees Celsius higher than in the previous century, a level never reached before. Indeed, the world record heat of 2007 is found already beaten while the year is underway.

And globally, the effects of this spiraling heat are manifested through the rising sea level overall with the Arctic ice that is, for the fourth consecutive year, fell below the 5 million km ² or a 38% reduction in comparison with statistics from 1979 when it was never dropped below this limit until 2006. Also for the consequences of this wave of heat, we have, the extreme weather events like heat waves in Russia, the huge floods in India and Pakistan through China, the unprecedented droughts in sub-Saharan Africa.

Africa at the heart of the heat wave

 The African continent has been particularly affected. Especially in sub-Saharan and Saharan Africa, scientists have recorded large positive anomalies in Algeria, Libya, Morocco to North Africa and Senegal, Burkina Faso, Cameroon, Chad, Niger to the SSA. For example, in Senegal and Burkina Faso, the meteorological announced unseasonably warm between January and March with 42 ° C in southern Burkina (which rarely exceed 40 ° C). And according to the site statistics "wetter.com", “Chad has recorded with the high temperature 43.6 ° C in N'Djamena through a heat wave varying between 43.2 ° C and 43.5 ° C from 18 to 20 February”. And research conducted in Senegal on the basis of emission scenarios of greenhouse gas (GHG) by the meteorological center predicted a warming of about 2 to 4 ° Celsius, a decrease in cloud cover and decrease in rainfall of 5 to 25%.

So many scenarios that demonstrate once again the intensity of what may be called climate change. A trend, that should continue with the same pace, until next September.

Heat waves and climate change linked?

Until now, scientists are trying to establish a formal link between extreme weather events and climate change as both phenomena seem to occur at the same time and have many similarities. However caution is always advised the side of scientists even if clear from recent research scientists on the one hand that increased concentrations of greenhouse gases could cause a considerable increase in episodes of extreme heat. Which suggests a series of positive reactions, where extreme events cause a release of carbon from natural systems, thereby exacerbating climate change.

Where evidence of a causal relationship between the two phenomena. But on the other hand, the arguments seem to be oriented toward the anthropological activity. This reopens the debate on the real causes.
