A new, peer reviewed study published in “Energy And Environment” comes to the conclusion that global temperatures have actually been dropping since 1986. This conclusion, at best, obliterates the claims that there is a global warming consensus.
The “Meteosat Derived Planetary Temperature Trend – 1982-2006” study took satellite derived temperature data from 1986-2006 that was collected using a European satellite system which measures thermal infrared radiation (similar to those red to blue heat maps that weather.com uses.)
“The amazing finding of the present study is that we do not observe global warming in the period 1982-2006, but significant cooling. What could be the cause?
The satellite data are from a reliable origin supported by the European
meteorological community. Their accurate calibration has received due attention and efforts from Eumetsat. Our processing of these data has been simple and straight forward, involving only noon and midnight image composition, averaging and a filter to eliminate cloud effects. We have created similar planetary temperature change images for the unfiltered, 10, 20 and 30 day filtered data, clearly showing convergence towards the longer filters, indicating that cloud influences were effectively removed.
Moreover, we do observe significant temperature increase at some locations which are due to human interventions, and which are quantitatively in line with the theoretically expected effects of these interventions. Therefore we believe the observed planetary temperature decrease for most of the hemisphere to be real.
The cloud filtered temperature change patterns, in figure 2c, indicate that the largest decrease occurs in the more cloudy regions of the hemisphere: the tropics and the temperate zones, while in the desert belt the temperature decrease is much smaller. This suggests that cloudiness changes could be the mechanism behind the observed global cooling since 1982: an increase in cloudiness would decrease global radiation and increase rainfall and evapotranspiration. Both effects tend to decrease the surface temperature.”
