Small volcanoes cool the Earth

July 6. Products of volcanic eruptions that do not reach the stratosphere once, after a while there is still carried by atmospheric currents and begin to reflect the sun's rays.

Scientists have shown that even small volcanic eruptions have a significant impact on the climate, saturating the upper layers of the atmosphere of their emissions. The study is published in the journal Science.

Previously it was thought that only large volcanoes that could throw ash particles directly into the stratosphere affect climate in the long term. Sulphur dioxide (SO2), one of the main products of volcanic activity, forms in the

Climatic features of the Earth — rapid and drastic changes

15.03.2013

 

According to a study by researchers from the University of Louisiana, the Earth even after a powerful glaciation can thaw almost instantly (in geological terms, of course). When this process is the originator of this carbon dioxide. When you consider that our civilization emits a huge amount of CO2, then the news of the great mobility of the earth's climate is of particular importance. Approximately 635 million years ago, almost the entire Earth bound ice. This glaciation, known as the

In the normal cooling of the earth fault Moss Weather and Climate

Primitive bryophytes plants can initiate a series of cooling the planet and cause a series of mini-ice age. Until now it was believed that the process of global cooling on Earth began about 100 million years ago with the advent of large plants and trees. But, according to Professor Tim Lenton of the University of Exeter, that mosses have had the greatest impact on the current climate.

Carbon dioxide surrounds the Earth like a big duvet. The more gas in the atmosphere, the higher the temperature. It is

Story of the continuation: nuclear event and an earthquake near Chicago

Story of the continuation: nuclear event and an earthquake near Chicago Danger Zone

January 30, 2012 a nuclear reactor 152 miles from Chicago, Illinois, let off steam with radioactive tritium.

As a result of a power nuclear power plant was closed at 16:18 (UTC). According to federal regulators, and representatives of Exelon Nuclear steam was released to reduce the pressure. Levels of tritium in the pair is considered safe.

Some facts about tritium

As in other cases of radiation, the risk of cancer increases. However, due to the fact that it emits a small amount of energy and leaves the

If carbon dioxide is not dangerous, then, probably, and nitrous oxide as well?

If carbon dioxide is not dangerous, then, probably, and nitrous oxide as well? It is interesting

The last year is one of the hottest in the history of Britain, and the level of carbon dioxide has increased by almost one fifth in the last 50 years. However, all have long known that global warming — the myth created by charlatans. Does this mean that no longer worry about? Not quite. In 2012, should pay attention to the next element of the carbon in the periodic table. Triumph or disaster nitrogen began in 1912 when a pilot plant in northern Germany

Mass extinction 252 million years ago coincided with an increase in carbon dioxide

Mass extinction 252 million years ago coincided with an increase in carbon dioxide Facts

Presumably the first living organisms appeared 3.8 billion years ago. Over the past 500 million years on Earth happened five mass extinctions. Scientists agree that dinosaurs may have become extinct 66 million years ago with the fall of a huge asteroid. Greatest mass extinction, during which lost some 90% of marine and terrestrial species, occurred at the end of the Permian period 250 million years ago. But the reason has not yet been established.

Researchers at MIT have come to two conclusions about the mass extinction.

Individual produce 135 times more carbon dioxide than volcanoes

The colossal, mind-numbingly hot, capable of spewing clouds of ash and rivers of burning lava volcanoes — a dwarf compared to the people in regard to the production of carbon dioxide.

Annually bipedal emitted approximately 135 times larger than carbon dioxide. In other words, people in three days produce as much as volcanoes issue for the year.

"The question is whether volcanoes emit more CO2, than the man — the most common in my email" —

The increase in carbon dioxide emissions on the island of El Hierro

The increase in carbon dioxide emissions on the island of El Hierro Facts

As a result of an earthquake on the island of El Hierro 4.4 3 November 2011 there was an unusually strong emission of carbon dioxide into the atmosphere. Carbon dioxide is predvulkanicheskim signal. Scientists claim that a powerful eruption yet to come. But if it happens on the island of El Hierro in the bay of El Golfo, or on the island of Las Palmas is not yet known.

The sleepy giant Arctic stirred

Permafrost region occupies nearly a quarter of the land surface of the Northern Hemisphere. (Image Hugo Ahlenius, UNEP / GRID-Arendal.)

June 11, 2013. The Arctic is very important for the understanding of the global climate. This is analogous to the canary in the coal mine for the whole Earth. The weather is changing in the Arctic faster than time to adapt ecosystems.

For a detailed study of what is happening in the Arctic Circle, NASA established a five-year project CARVE (Carbon in Arctic Reservoirs Vulnerability Experiment), the purpose of which — measuring the output of carbon dioxide and

Carbon funnel narrowed

Most climate models predict that the world's oceans and plants absorb about half of the carbon dioxide that we release into the atmosphere.

Because plants absorb CO2 during photosynthesis, a hypothesis that they play a large role sewer (carbon sink), which will take off much of the carbon dioxide formed by burning fossil fuels. Some scholars have even suggested that the increase in the atmospheric concentration of CO2 would be beneficial for the plants, saying that greens will grow more vigorously, absorbing more of this greenhouse gas. Climate models consider that the oceans ate about 30% CO2, released over the
