Flood disaster, which occurred simultaneously in several countries, suspected to be the effects of global warming phenomenon is exacerbated by the damage caused humans. The weather is warming affects rainfall patterns in some places.
Similarly, according to scientists from the United States (U.S.) and Australia.
In recent days, several countries have problems with flooding, which caused many casualties.They are Australia, Brazil, and Sri Lanka.
Climate observers from the University of California at San Diego, Richard Sommerville, said the floods caused by climate change due to global warming which is formed due to human activity. Combustion routinely performed many humans, such as fuel consumption, making the world hotter temperatures.
This happens because every time humans using fossil fuels such as coal, oil and natural gas, a lot of carbon dioxide released into the atmosphere.This, says Sommervile, which makes the air temperature in the atmosphere, ocean and land heats up.
"The world was heating up and the scientists are very sure most of the warming is due to human activity," said Sommervile quoted from page ABC, Thursday, January 13, 2011.
Sommervile said yesterday that 2010 was the warmest in the last hundred years. According to the NASA report, the year 2010 was the hottest year in 131 years. The highest temperature occurred between January to April last year, NASA reported the temperature reached 56 degrees celsius. This is 1.24 degrees higher than the average temperature of the hottest in the 20th century.
Temperatures are heating up in the oceans and continents causes the evaporation of sea water to be faster than usual. Sommervile said this condition makes the air becomes more humid.The result is rain with a very high intensity or even snow in summer.
"Because of all the world's water cycle increases the heat, then more water in the atmosphere today than the average amount of recent years.You'll see more rain and flooding, for example in Australia, "said Sommervile.
Scientists from the University of New South Wales, Matthew England, as reported by Press beritaAssociated office, said that global warming will make the cycle of flooding in some parts of the world will become increasingly common.
"Floods usually occur once every hundred years can turn into a one-time in 20 or 30 years due to climate change. We can say that this will be more frequent and often again in the future, "said England. (Umi)
