Sea levels will rise slightly

May 15, 2013. It's not as bad as we were still talking. Comprehensive study of the behavior of ice sheets revealed that in 2100, its melting will add no more than 36.8 cm to sea level. In other words, the growth in this century will not exceed 69 cm

Water rises, because along with the planet heats up and expands, and also because the glaciers and ice sheets melt and slide off into the ocean. The rate of sea level rise is unknown, because prognosis as to how much will be lost when the ice, proved to be very difficult.

New information about sea level rise Scientists have shown

Recent calculations of scientists have shown that the level of the Pacific Ocean off the west coast of the U.S., especially in California, will be significantly more by 2030 and will be about 15 cm to the 2100 figure will rise to 1 meter, which will flood the famous beaches, sand dunes and expand bays and estuaries.

Land will decrease by approximately 30 m in length in a mountainous part, a flat reduction would be much more serious. Swampy areas will exist no more than 50 years and will

Warming could lead to the extinction of up to 10% of bird species by 2100

Changes in the Earth's climate by 3.5 degrees by 2100, could lead to the disappearance of the 600 to 900 species of birds, according to an article in Biological Conservation.

According to international experts on climate change, Earth's average temperature by the end of the 21st century may rise at most by 1.8 degrees, and at worst — 4.6.

The study was conducted by an international team of scientists led by Chagan Shakerioglu (Cagan Sekercioglu) from the University of Utah.

"With the increase in surface temperature by 3.5 degrees by 2100, may disappear from 600 to 900 species of

Warming eats territory of America

Rising sea levels caused by climate change may already be in 2100, threaten the very existence of the 180 U.S. coastal cities. This is stated in the new study, and emphasizes that the most severely affected Miami, New Orleans and Virginia Beach.

In previous studies on the probable rising waters by the end of this century and a mathematical model of expected volumes of sea level rise. But in the course of this analysis were used in the calculation of the city with a population of over 50,000 people in 48 states.

Cities along the southern coast of the Atlantic

UN urges Russia to create a network of observation thawing

Russia, along with the U.S., Canada and China, to establish a national network for monitoring the state of permafrost thaw in 2100, which may enter the atmosphere to 135 billion tonnes of CO2-equivalent, according to a new report by the UN Environment Programme (UNEP) .

UNEP study addresses the status of permafrost, which accounts for over a quarter of the land area in the Northern Hemisphere. The report concluded that the potential impact of melting permafrost and the gradual release of "locked" in its carbon, the amount of which, according to their estimates, can be up to 1.7 trillion

It will be much warmer than the predicted worst-case scenario

According to a new study by the end of the century could be much warmer than previously estimated. They say that the average temperature will be much higher than indicated in the worst case scenario of IPCC. In the event of an accident at a nuclear power plant in the Japanese prefecture of Fukushima reality was far worse than expected in theory. The same applies to the debate about climate change.

A team of American and Swiss scientists simply took into account the global population growth, resulting from the UN projections, per capita energy consumption and the possible combinations

By 2100, the world population could reach 11 billion people

26.06.2013

 

According to the statistical analysis, the Earth's population could reach 11 billion by 2100. This is 800 million more than anticipated in 2011. Basically, it is because the birth rate in Africa has not fallen as quickly as planned. According to the UN, by October 2011 the world population reached 7 billion, which is a surprising amount, compared with 5 million in 8000g. BC and 1 billion in 1805.
