Con una selezione accurata delle varietà di specie plant food, Europe and North America may be able to reduce a century the global temperature of the earth by about 1 ° C. This is the latest issue of the journal Current Biology , by a team of researchers from the 'University of Bristol . The reflection of solar radiation (albedo) crops causes an overall cooling of global temperatures, more than does the natural vegetation. Then select the crops to higher albedo could have some very significant results.
" current choosing between varieties, the our estimate on the increase of reflection " explains Andy Ridgwell, director of the study " leads us to predict that summer temperatures could be reduced by more than 1 ° C for much of North America and in the middle latitudes of Eurasia . The proposal "says Ridgwell" is to choose between different varieties of the same kind of culture to maximize the reflection of light non-but change the type of crop. "
According to the researchers' calculations, this choice eliminate the effect of 195 billion tonnes of CO2 emitted into the atmosphere over the next 100 years.
