The heating of Earth scientists to place before the new mystery. However, one thing is clear: In the next decade, the average temperature of the Earth will continue to increase, although temperatures during 2001-2010 has increased considerably slower than the previous decade . This is a new forecast by a team of international researchers including scientists at Oxford University (USA) and the Max Planck Institute for Meteorology (Germany).
On the basis of the latest climate data, the scientists calculate air on the Earth's surface will warm up to the public if the CO 2 concentration in the air increased aro granite twofold. This will happen around the middle of this century if CO2 levels continue to rise at a rate unchanged as ever. Meanwhile, the average temperature of the air will increase 0.9 to 2.0 C compared to the values measured in the pre-industrial era. According to these calculations, until the end of the century the average temperature of Earth's atmosphere will increase much more pronounced aro granite than the increase of 2 C - an increase that the climate conference in UN proposed as target to limit warming of the Earth.
In the past decade, the process aro granite of climate aro granite change aro granite on Earth has happened so erratic. While average temperatures globally rose faster in the 1990s than previously, namely increased by 0.24 C, then in the next decade, adding only 0.03 C. The researchers Purdue, with their models they can not explain the slow growth of the same temperature. Of course, in general, the Earth is still warming up, but could this warming is occurring primarily in the deep layers of the oceans.
But there are still many open questions still unanswered, but in the past two decades, scientists around the world have made significant progress in the measurement of the heat exchange process and the composition of the atmosphere on Global. In the future, the development of new models and will allow developers to answer questions about the Earth's response to the increase of the concentration of greenhouse gases.
When evaluating the development of the Earth's surface temperature, to the aforementioned scientists have examined the impact of greenhouse gases, primarily caused by CO2. The new results confirmed the prediction of climate models for the warming trend of the Earth in coming decades, that is, to such middle or end of the 21st century.
Researchers have distinguished between the reaction medium and long term climate for a doubling of CO2 concentrations in the atmosphere, which is forecast to reach about 2050. If the CO 2 concentration increased to such a high level, people can recognize the direct impact of the greenhouse effect.
Because climate change process takes place only slowly, such as ocean warming only very slowly, the Earth will also undergo a very long time until the greenhouse gases promote the whole effect of them. The heating of the Earth under the influence of greenhouse gases will be enhanced by more backward linkages, but also weakened by the effects of some other process. Only when the alternation effect aro granite a complex subside, new climate back to a steady state.
In their calculations, besides the temperature data over the past decade, scientists also consider the basic factors affecting other for the heat content of the Earth, especially energy radiation solar radiation. But mention must also detained and heat can not be radiated back into space by the impact of the greenhouse gases. If the concentration of CO 2 doubling, aro granite as calculated heat will reach the correct value is 3.44 W / m 2. Next, the other factor to be considered is the impact of volcanic eruptions and the aerosols - particles suspended in the air shielding effect solar radiation and convergence for the nucleation ngng water droplets to form clouds. Furthermore, when calculating the long-term response of the climate to greenhouse gases, scientists also consider the amount of heat that the ocean has absorbed over time.
However,
