As the board of international scientists, global warming is increasingly becoming a cause of severe storms, droughts, heat waves, forcing the entire nation to prepare for the onslaught of deadly and costly natural disasters.
The biggest danger is densely populated poor regions of the world, but no part of the world from Miami to Mumbai is safe from disasters. Scientists, Nobel laureates, forecast strengthening of tropical cyclones and an increase in floods, rain and extreme heat.
The report consists of 559 pages, a set of artificial factors such as climate change, migration and poverty, identified as the main causes of observed and future disasters.
Intergovernmental Council scientists on climate change, the UN established in 1988, is studying the slow rising temperatures and sea levels as the effects of climate change. The report first drawn attention to less typical, but noticeable changes in the average cost of 80 billion dollars annually.
"People notice the change in climate and weather conditions only in extreme cases where there is a loss and insurance payments, when everything is falling apart before our eyes. In the world there are many places that have been destroyed, and the risk of natural disasters is always and everywhere, "- said Chris Field, an ecologist at the Carnegie Institution in Washington.
In the coastal regions of the U.S. destruction of property from hurricanes and rising sea levels could rise by 20% by 2030, and in some parts of Texas, the vulnerability can be doubled by 2080. To date, the U.S. has annual losses from natural disasters in the $ 20 billion, while in the 80's it amounted to 2 billion, adjusted for inflation. In 2011, the damage was estimated at $ 35 billion, most of which are due to a tornado, but so far scientists have been unable to prove a direct link tornadoes to climate change.
More than 2.7 million people live in regions prone to major flooding. Around the world there are places in the near future may become uninhabitable as a result of extensive flooding. One such place is the Indian city of Mumbai, where in 2005 a day has dropped about 90 inches of rain, taking the lives of thousands of people and causing massive destruction. Other cities include Miami (USA), Shanghai, Bangkok and Guangzhou (China), Ho Chi Minh City (Vietnam), Yangon (Myanmar), Calcutta (India). Residents of the small islands like the Maldives, will likely have to leave their homes because of the threat of storms and rising sea levels.
Report is unique because it focuses on managing the risks and benefits of taking precautions. The word "risk" referred to by the Board of scientists 4387 times.
Springfield considers Bangladesh to one of the poorest countries that are prone to storms and flooding. In 1970, Tropical Cyclone Bola third category took the lives of 300 thousand inhabitants, and in 2007 by an even more powerful cyclone killed 4,200 people. Thus in 2008, due to the same effect in the Myanmar cyclone killed 138,000 people. This clearly proves the effectiveness of preparation for natural disasters.
Noted a paradox which is that rich countries are burned most fossil fuels, at which the carbon dioxide emissions, contributing to climate change. But most of all from climate change affects the poor underdeveloped countries whose carbon footprint is small.
The study also predicted that some storms could increase, for example, in the U.S., while the other — a little faint. Temperature records will continue to grow around the world, especially in Alaska, Canada, northern and central Europe, East Africa and northern Asia. For example, in March 2012 the United States was established 6800 record high temperatures.
If you add a variety of record results, including increasing financial losses, it will be difficult to deny the existing "climate signal" that the world is undergoing major changes.
