Looks as though my active zone measuring system is good. The fallen big trees show the depth to rock or frozen water or groundwater surface. Smaller trees will do better.

Alaska's North slope doesn't get snow? I was using glacier tips as extreme edge. But any snow is edge with greater or lesser duration. In Ottawa we had full snow for 5 months and another 4 months of sometimes snow.

My model in 1988 explained such heating, or cooling if going the other way. Snow cover for less of the year causes rapid heating due to sun on stone and a feedback loop. When snow is gaining ground then feedback cooling happens as plants, rock and water are covered in ice, reflecting light.

At the edge 0.7 degrees is a big difference so the edge has been pushed north in the northern hemisphere as the little ice age ended which is a lengthy process not instant.

At the equator a 1 km wide strip of snow reflects a huge amount of light because that would be 40,000 km2. At the north pole a 1 km wide strip of snow around the pole is only about 4km2.

At 45 degrees latitude the area of a strip 1km wide would be 27,000 km2.

We could do some calculus and calculate the reflective area as snow cover grows from zero at the pole to total at the equator (snowball earth).

Incoming sunlight in the Arctic is weak in summer and zero in winter whereas at the equator it's full nuclear powered heating year round.

There has been a century of warmer. The last 20 years not so much. I predict cooling now. We'll soon see.

Meanwhile Alarmist predictions for the last 30 years have been a joke.

New York is above sea level. So are Florida and Rarotonga. Children still experience snow ... the Beast from the East for example and rumour has it that USA had snow somewhere last winter. The north pole still has ice over it ... silly Al Gore.
