Cover crops grown in fields during winter may be warming temperatures in the northern United States and southern Canada, according to a new study by scientists at the National Center for Atmospheric Research. The crops, a land management strategy farmers use between growing seasons, create a darker surface than a snow-covered field, absorbing more heat from the Sun and producing a local warming effect.
