Global Warming Effects

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 inc...

The average temperature on Earth is mesaured through a balance of the different forms of solar and terrestrial radiation. Solar radiation is often called "short" radiation, because the frequency of the radiation is relatively high, and the relatively short wavelength in the vicinity of the visible part of the electromagnetic spectrum. Radiation from the earth, on the other hand, is often referred to as "long" radiation, because the frequencies ar...
