Heating cause increase in the amount of snow in the region.
Thus, temperature at the center of the continent would be 0.5 ° C lower.
 
The impact of rising global temperatures in the Antarctic may be lower than predicted by scientists, thanks to increased snowfall in the central region of the continent, says a study released by the National Center for Scientific Research (CNRS), France.

According to research, a partnership between the geophysical laboratory of the environment in Grenoble with the University of Laval, Canada, the predictions of warming would have to be reviewed with "low of 0.5 ° C to the center of the southern continent."

The temperature increase in Antarctic imply a greater number of precipitation, and therefore a snow more "white" to reduce the effect of the climate in the center of the continent. If there is an increase of 3 º C temperature in the deep snow would increase the albedo, radiation that reflects any surface.

According to scientists, a high albedo would cool the planet because the light or radiation absorbed and utilized is minimal - the study continues, the higher the albedo of fresh snow.

The studies, published in the journal "Nature", to assess better the role of snow in the models used to predict the evolution of global climate, full note of the CNRS.
