Snow & Ice


Snowfall % Changes, 1973-2023

Mean annual northern hemisphere snow cover is 9.9 million square miles, or 25.6 million square kilometers   The minimum is in August and the maximum in January.

The northern hemisphere snow cover fell 7% over 1967-2021.

Over 2000-2021, mean annual snow cover shrank 9% for Asia, 2-3% for North America, 10% for Europe, 17% for South America, 0% for Australia-New Zealand, and 17% for Africa.

We’re 60 Years Too Late to Stop Global Warming, Sea Level Rises 1120 - Among other things, snow cover around the poles shrinks (especially melts earlier) as the climate warms.  This allows Earth to absorb more sunlight, into the darker ground and plants beneath the snow.  This increased energy, in part, heats the air above the ground, for still more sensible warming.
