Snow is part of Earth’s seasonal cycle, with a majority of snow covering the Northern Hemisphere. When snow is pristinely white, it is highly reflective; a vast amount of sunlight that hits the snow is reflected back into space rather than absorbed.
Otherwise, snow typically melts seasonally, causing runoff into streams and rivers and recharging groundwater. Major snow-prone areas include the polar regions, the northernmost half of the Northern Hemisphere, and mountainous regions worldwide with sufficient moisture and cold temperatures.
Snow, the solid form of water that crystallizes in the atmosphere and, falling to the Earth, covers, permanently or temporarily, about 23 percent of the Earth’s surface.
Snowfall patterns are shifting as the climate warms, with many regions already seeing declines. These shifts impact water supply, ecosystems, winter recreation and hydropower generation. As...
