Plants to reflect the rays of the sun?

The cultivation of plants reflecting some sunlight in the atmosphere could lower the temperatures observed on Earth.

With this device in Europe and North America could reduce the temperature of 1 ° C in summer. This represents the equivalent of a global cooling of 0.1 ° C, 20% of the temperature rise observed since the industrial revolution. Scientists say the choice of crop varieties in order to control the climate. Dr. Ridgwell said: "In selecting among the varieties of current crops, we estimate the most optimistic we believe that the summer temperatures could fall by more than 1 ° C throughout much of North America and the 'Eurasia. Ultimately, the regional climate cooling could be achieved through selection or genetic modification of crops, optimizing their albedo. "
