Water resources will fluctuate increasingly and become more difficult to predict in snow-dominated regions across the Northern Hemisphere, new research shows.
According to a new study published in the journal Nature, the global ban of chlorofluorocarbons and other ozone-depleting substances prescribed by the 1987 Montreal Protocol and its subsequent amendments has prevented the eventual collapse of the ozone layer, thereby shielding vegetation from harmful ultraviolet radiation.

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.
