How to prove anthropogenic global warming? For example, you can compare the results of two climate models: one - greenhouse gases produced by humanity, and another without them. At the same time it turns out, what role in warming is played by natural factors: solar activity, volcanic eruptions, etc.

Still very strange thing that global warming: someone from him hot, and someone - on the contrary. Here and scientists from the U.S. he is linked abnormally cold winters of recent years that regularly froze residents of the Northern hemisphere. More specifically, with very rapid melting of Arctic glaciers, the reason of which is the global warming.

The flowering of the Black sea becomes a record, it lasts for a month and covers the entire deep-water part of the sea, is spoken in the message of engineering and technological center (ITC) "Center".

The idea of climate change itself is already in the process of final refutation of climate alarmists who believe that human use of fossil fuels is responsible for catastrophic global warming. This is because the natural cycles already deployed towards cooling, global temperatures have already reduced about 10 years, and will continue to fall for another 10-20 years.

Humanity's time to say goodbye to a sinking Amsterdam, Venice, Tripoli, Yokohama and the Maldives.

In the beginning of 2011 in the US and Europe lashed by severe frosts, although in Greenland and Alaska was unusually warm. This year, in late winter in the US and Europe, in contrast, was hot, yet the air is cold hung over Central Europe and Asia. In the Northern hemisphere extreme weather conditions in winter are usually associated with a negative phase of the Arctic oscillation - the rose of winds, which are dominant in the polar region. And scientists come to the conclusion that changes in the Arctic, may have led to long stay oscillations in a negative mode.

In this century on Earth can happen irreversible environmental collapse, and the global ecosystem could collapse suddenly, not gradually, as previously thought

"So what that the Arctic ice is melting? We do not live in the Arctic" - so says the majority of the population of Europe. Belief in global warming Europeans diminished after the abnormally cold winters.

Our planet is threatened by the sudden end of the world because of the collapse of the ecosystem

The earth approaches "critical point" in climate change, which will lead to a rapid and irreversible process of destruction of the environment. To such conclusion the group of scientists headed by a biologist at the University of California at Berkeley Anthony Barnoski. They published his article in the journal Nature.

Earthquakes and volcanoes can devastate whole regions. Solar storms threaten modern infrastructure. How often happen very large catastrophe? The researchers examined the time intervals: they turned out to be shorter than it was supposed.

An international team of scientists has again appealed to politicians with a demand to recognize the danger, hanging over humanity.

Недавно ученые составили модель предполагаемого извержения супервулкана, расположенного в Йеллоустонском национальном парке в США, которым весь прошлый год пугали СМИ. Оказалось, что даже если это случится, катастрофы не произойдет: извержение будет несильным, и уже через десять лет Америка полностью оправится от последствий этого громкого события.

Пустыня Сахара — одна из крупнейших пустынь мира. Сахара простирается через большую часть Северной Африки, покрывая 9 миллионов квадратных километров. Фактически, Пустыня Сахара занимает 30 % всего африканского континента. Это — самое жаркое и горячее место в мире с летними температурами, которые часто превышают 57 градусов по Цельсию. В пустыне выпадает ежегодный ливень и очень мощные песчаные бури, поднимающие песок на 1000 метров в высоту и перемещающие дюны.

Еще в те времена, когда нога человека не ступала на землю Антарктиды, вокруг загадочного южного материка строилось множество предположений и гипотез. Когда теории о постепенном движении материков завоевали себе место в науке, ученые бросились решать загадку — откуда приплыл Ледовый континент?
