Researchers at the University of Colorado have warned that Arctic sea ice will melt in a record manner this year and may hit an all-time low come September.
The researchers added that the level of the ice may be the lowest since records began in the 1970s.
Earlier the same research team had predicted record levels would be hit this April itself, but the quick melting of ice in the area in July has forced them to alter their forecast. In April the team had said there was a 33 percent chance of low Arctic sea ice levels, but this time they have increased the risk estimation to 92 percent.
"Similar to the way the El Nino pattern affects weather in the United States, more ice melt could change rain patterns and temperature patterns in the middle of the United States, which could have economic impacts on farmers," said Sheldon Drobot, who is the chief forecaster of the CU, Boulder team.
The implications of this melting on the level of sea water are massive. The rapid disintegration of the Arctic Ice may very well cause the Atlantic and the Pacific to be connected by a shipping route, the researchers predict.
"There is an element of human activity in the cause of this melt," said Drobot. "Natural variations can't explain everything."
The CU-Boulder team monitors the ice levels in the Arctic ice in March and September because these months will show the maximum and minimum readings of the same. The researchers said that this year's predicted record low was a direct result of high levels of greenhouse gases.
