In Mai 2004, Qiang Fu, from Washington University, declared that it is now certain that the lower atmosphere temperature is rising as fast as the temperature of the earth.
Comparison of surface temperature to satellite-estimated lower-troposphere temperature
Before this study, scientists were thinking that the temperature increase in the troposphere (up to 12Km over the surface of the earth) was lower than the earth temperature.
However, it appears now that this first study was wrong due to some wrong analyses of the satellite data.
The new study published in the magazine “Nature” indicates an increase of approximately 0.2 degrees Celsius per decennia, similarly to the earth rising temperature.
Those results are important because for many years, the variation between the satellites data and the temperature at the surface of the earth created debates on the global warming reality.
Those debates are now over and we know that Global Warming is a problem we need to address.
