America attack spider killer

In America, the true biological unfolding disaster. What's going on? Frantic pace began to multiply very dangerous type of spider called the brown recluse or scientifically Loxosceles Reclusa. But what contributes to this growth population of the species? According to scientists, the most likely cause — climate change is taking place in North America.

Of course this kind of poison is not so dangerous, that would kill an adult, but he is strong enough that would cause harm to a child or a sick person. According to the most pessimistic forecasts, to over the next 50-70 years

Increased drought in East Africa

A new study shows that participating drought in East Africa over the past two decades, is likely to continue after the continuous rise in global temperature. Because of this, approximately 17.5 million people from the Horn of Africa face the risk of potential shortage of food.

The study was published in the journal Climate Dinamics scientists from the U.S. Geological Survey (it is the USGS, — annotated. Interpreter) and the University of Santa Barbara in California. USGS, along with the U.S. Agency for International Development have identified areas of potential drought and famine in order to guarantee

Arctic may no longer have to freeze in the summer 2019

In 2007, Wieslaw Maslowski of the Naval Postgraduate U.S. and his colleagues predicted that the summer Arctic will be ice-free in 2013. After enduring a barrage of criticism, the researchers have made changes to the computer model and got a "more precise" date — 2016-th.

Plus or minus three years.

The new model reflects the interaction between the Arctic ocean, atmosphere, sea ice and rivers carrying freshwater into the sea. "Last time we just extrapolate current trends for the future, — says Mr. Maslowski. — Now we come to the question more systematically. Our model of the Arctic climate

Flew past the Earth 10-meter asteroid, the evening is expected to further

By Earth on Wednesday morning flew ten-asteroid 2011 GW9, night "visit" expect another — 2011 GP28, the size of which is about eight feet, according to data published on the website of NASA. Asteroid 2011 GW9, discovered April 4, flying past Earth on Wednesday, at 04.58 GMT (08.58 MSK) at 198.9 thousand kilometers, which is about half the distance to the Moon. According to astronomers, the size of a celestial body is from 6.3 to 14 meters. Another asteroid 2011 GP28 (also first seen on Monday) comes closer to the Earth on Wednesday evening, 19.36 GMT (23.36 MSK). He will

These are two huge whirlpools — none of these were not known on Earth. Has been suggested that they have a strong influence on global climate change in recent years," — the magazine writes.   "Funnels found 200 km from the coast of Guyana, Suriname and French Guiana, as it

UN summit on climate change in Cancun

Russia supported the draft decisions of the Conference of the Parties to the UN Climate Change Conference in Cancun, which is actually a development of the ideas laid last year in the Copenhagen Accord, told RIA Novosti the head of the Russian delegation, presidential adviser on climate change, Alexander Bedritsky.

A few hours ago, the delegation received two draft decisions to be taken within the two negotiating "tracks": a long-term cooperation (LCA) and the Kyoto Protocol. Paper on LCA — a prototype of future post-Kyoto agreement — is a whole package of documents relating to developing countries, emission reduction measures,

The core of the Earth affects the climate

Modern models of the climate, too simple, because it does not take into account a number of factors, which may include the costs and shift the Earth's axis after the earthquake. This goes to show a previously unknown relationship between the growth of average annual temperatures and the rotation of Earth's core, NASA scientists discovered and French meteorologists.

Critics of modern dynamic models, which are calculated on the basis of climate change back in time and forward, quite rightly criticized in the superficiality of their authors, moreover, in a literal sense. Even in the most complex scenarios of heat

Arctic could threaten the ozone hole, similar to the Antarctic

Abnormally low temperatures in the stratosphere ozone layer, which protects the Earth from ultraviolet, caused a sharp decrease in its thickness — a few weeks layer "lost" nearly doubled, according to RIA Novosti specialist German Institute for Polar and Marine Research, Alfred Wegener Institute (AWI) Markus Rex (Markus Rex). According to Rex, surveillance network of more than 30 research stations in the Arctic and adjacent areas show that in the last few weeks at the appropriate heights destroyed about half of all ozone. "This year, the situation with the fall of the concentration of ozone seems to be going to,

Global climate change can create the conditions for outbreaks of dangerous diseases

Global climate change can create the conditions for outbreaks of dangerous diseases, especially cholera. With such a warning was delivered by Professor University of Maryland / USA / Rita Colwell, who participated in the international conference organized by the "Canadian hydro network organizations" at the University of Waterloo. More than 300 experts from different countries to discuss prospects in the Canadian capital formation in 2020 of the world market of technology and services for cleaning, filtration and disinfection.

According to Professor Colwell, the threat of renewed outbreaks in North America is associated with more frequent and severe thunderstorms, which can
