Increasing temperature of Earth has has put poles for the first time directly attributable to human activities, according to a study. The work, by an international team, is published in the journal Nature Geoscience. In 2007, the UN body on climate change presented strong evidence that the global average temperature increase is largely due to human activities. That contradicts the idea that this was a result of natural processes, such as an increase in intensity on sun.

At the time, there was sufficient evidence to say this for sure about the Arctic and Antarctic.
We really can not continue to pretend that it is natural that guides these variations to such big changes. Now this gap in research was connected, according to scientists who have made a detailed analysis of changes in temperature at both poles. The study indicates that humans have contributed to global warming in both regions. Researchers result was expected in the Arctic – a result of the recent sharp increase in melting of sea ice in summer in the region – but the  temperature changes in Antarctica have been so far difficult to interpret.

Today study, according to the researchers, suggests for the first time there is a discernable human influence on both the Arctic and Antarctica.
The research team took the temperature changes over Earth’s polar regions and compared with two sets of climate models.
A series assumes that there were no human influenza set the other was taken there. The best fit was with models that assumption that human activity including burning of fossil fuels and ozone depletion has played a role. According to one of the researchers involved in the study, Peter Stott, head of climate and monitoring for the award Met Office, formally showing that the Antarctic has been influenced by human activity was the main development:

In recent IPCC (Intergovernmental Panel on Climate Change) report, for example, he said, “unable to make a statement on the Antarctic, because this was not done a study at that time.
“But yet, when you do that you can clearly see a fingerprint found in humans. We really can not claim more than is natural that guides these variations are very big changes that we are seeing in our climate system.”
Professor Phil Jones, director of the Climate Research Unit of the University of East Anglia, said: “Our study is certainly close some loopholes in the latest report by the IPCC.
“But I still think a number of people, including some politicians are reluctant to accept the evidence or do nothing until they refused to say specifically that a particular event was caused by humans as a serious flood or somewhere even a heatwave.
“Until you go to small events in time and space, there will be people who still doubt the evidence.”

The amount of solar radiation absorbed on Earth is only a small fraction of the total solar radiation into the atmosphere. Sun value per 100 units incident, about 30 units found in the room by one of the clouds, air, deliberation or regions on earth. This capacity for reflection, the albedo of the planet Earth, and it should not be set in the time since the magnitude and spatial distribution of the training of considerations, such as clouds and ice, may change. The 70 units of the sun’s rays, which are not reflected May be absorbed through the air, the clouds or the surface. In the absence of other complications to the thermodynamic equilibrium of the earth’s surface and the atmosphere must radiate these 70 locations in space. Soil temperature at the surface (and the lower layer of the atmosphere, especially in contact with the surface) is the size of the emission of radiation from the law by Stefan-Boltzmann.

Land of the energy budget is by greenhouse gases. Traces of gases with certain chemical properties of the so-called greenhouse gases, especially carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)-absorb a portion of the infrared radiation by the Earth’s surface. Because of this recording, a fraction of the original 70 employees not directly to the escape. Because greenhouse gases exactly the same amount of radiation they absorb and also because this radiation is spent in all directions (which, as far down as shown above), the net effect of absorption by greenhouse gases is an increase in the total amount of radiation emitted down on the earth’s surface and lower atmosphere. To maintain the equilibrium of the earth’s surface and lower atmosphere emits more radiation than the 70 employees. Therefore, the temperature must be higher. This process is not quite the same as in a real, the greenhouse effect, but the effect is similar to an end. The presence of greenhouse gases in the atmosphere leads to a warming of the surface and lower atmosphere (and cooling earlier in the atmosphere) in comparison to what was expected in the absence of greenhouse gas.

It is important to distinguish between “natural” or background, the greenhouse gases of “enhanced” greenhouse effect associated with the activities of humans. The natural greenhouse effect is with the properties of the surface of natural warming of the atmosphere of the earth, particularly the water vapor, carbon dioxide and methane. The existence of this effect is by all scientists. In fact, in his absence, the mean temperature of the earth from about 33 ° C (59 degrees F) cooler than today, and the earth would be frozen and probably planet uninhabitable. What was controversial is the so-called greenhouse effect, with an increase in the concentration of greenhouse gases from human activities. Especially by the burning of fossil fuels increases the concentration of main greenhouse gases in the atmosphere, and these higher concentrations have the potential heat up the atmosphere by several degrees.
