Drought in Texas last year, a wave of fires in Russia in the summer of 2010 and 2012 are examples of natural abnormal phenomena, which in any case would not have happened if not global warming, says the government expert on climate change, James Hansen.

According to the scientist, if not to take decisive action to control carbon over the next 50 years, heat waves will become commonplace, and it threatens a sharp shortage of food and water.

It is noteworthy that the published study Hamsina, warning of impending disaster, is the work of many months and was prepared before the dismal record of the fall of the U.S. crop due to drought (the lowest level in more than 50 years).

"We now know that the chances of these extreme weather events take place in the natural order - without climate change - would be miserable" - notes the report James Hansen, who is a fellow of the American National Aeronautics and space. "The natural weather changes from day to day and from year to year," do not explain these anomalies, he says.

On Friday the Ministry of agriculture of the USA has again lowered the forecast of the harvest of corn and soy beans because of the progressive drought. U.S. Department of agriculture has lowered the forecast of the corn crop this year on 12%, and the forecast for soy beans - by 4.8%.

Analysts of the Ministry noted that 37% of crops of soybeans are in bad or very bad state. In a similar situation are 48% of the area sown with corn, and 57% of pastures. The consequences of low harvest will affect the economy. The Ministry predicts that food prices next year will be 4.5% higher than this.

Because of the serious losses of yield of forage crops for livestock will increase the costs of maintaining the herd. Many manufacturers of pork and beef is not the same insurance as farmers who grow corn or soy.

In Russia also have to prepare for the increase of prices for bread and meat. So, on Monday, the newspaper "Vedomosti" writes about the intention of the producers of bakery products to raise the prices for the products by 3-10%. "If you continue to let go of bakery products at old prices, our company will not have enough money even for a payment of wages, on payment of taxes or for the purchase of raw materials for production, which will lead to a stop of the enterprise", - quotes the edition letter Bryansk manufacturer.

On Thursday Deputy head of the Ministry of agriculture announced that because of the drought in many regions of Russia, the government can reduce the forecast for the grain harvest up to 70-75 million tons, that is more than 20% below the volumes collected in the past year.
