It is clear that from 2006 to 2012, the average insolation reflected by the Greenland ice sheets is decreasing. This indicates that each year, the amount of solar radiation that the ice sheets are able to reflect is decreasing. The level of insolation reflected is dependent on the area of ice sheets capable of reflecting the solar energy. Since the insolation reflected has decreased, this may mean that the area of the ice sheets has decreased as well.
Why Farmland is Abandoned:
As groundwater pumping increased, water tables dropped, requiring pumping from deeper levels and at greater costs. Because of the increased cost, irrigation became prohibitively expensive. Farms thus were abandoned as unprofitable, especially in Cochise and Pinal counties.
