Is the scorching of the planet earth at hand? The seasons are not only becoming hotter but it is also becoming dryer. Scientists have declared the year 2014 as one of the hottest in Earth's history and now another survey has revealed that the driest spell is about to hit the planet.
Three Institutions whose expertise concerning Earth's climate are beyond question, are in one mind that the worst dry season is about to come. NASA, Columbia and Cornell Universities, agree that it's not only California that should prepare for the worst but the entire country as well. The drought condition about to happen will be the worst in a 1,000 years. Included are the south-west states and the central plains.
Man is highly responsible for all the coming warming and drought effects according to the scientists.
"Nearly every year is going to be dry toward the end of the 21st century, compared with what we think of as normal conditions now," said Ben Cook from Nasa's Goddard Institute for Space Studies, the lead author of the study. "We're going to have to think about a much drier future in western North America."
The increasing temperature and the longer drought will wrought havoc in the area devastating agricultural system, wiping out both the crops and the animals resulting to sky high prices of both meat and plant products.
The researchers added that the mega-drought is expected to last for 35 years or more. The research analysis includes the effect of the rise in carbon emissions.
The coming drought is expected to last for more than one third of century or 33 years. The research also includes the ramifications of the increase in carbon emissions.
The researchers created a climate simulation program where in the factors that affect the weather include the rate of rising emissions.
The research team came up with a model program which includes the factors that that has bearing to weather that incorporate the rate in the spiraling emissions.
According to Dr. Cook, "These mega-droughts during the 1100s and 1200s persisted for 20, 30, 40, 50 years at a time, and they were droughts that no one in US history has ever experienced."
"The droughts people do know about, like the 1930s 'dustbowl' or the 1950s drought or even the ongoing drought in California and the south-west today – these are all naturally occurring droughts that are expected to last only a few years or perhaps a decade. Imagine instead the current California drought going on for another 20 years."
