I was thinking about publishing an essay on "The Last White Christmas" on how every little town and village was going to have it's last white Christmas as Global Warming took them out of the snowfall regime. That there just wouldn't be a white Christmas for that town, ever again.
Except that Global Warming is melting the permafrost all over Siberia and Canada and the melting permafrost is flowing down the rivers to the Arctic and freshening the Arctic Ocean, which is making it easier for the sea to freeze and form pack ice, which is making winter come a few weeks sooner each year.
Until the permafrost finishes melting and the Arctic Ocean resalinises, the ice pack will form faster and sooner than it used to.
The permafrost is only a few feet thick at the southern side but it is hundreds of feet thick in the areas of deep cold. It make take a while before the permafrost is completely gone.
Eventually the permafrost will be melted down far enough that the yearly melt won't be important. That make take ten or twenty years. Then the pack ice will finally go away.
So enjoy a white christmas while you can.

The only problem with this story is that it is wrong. The Arctic Ocean is losing the isolation that it had before and warm waters are helping to finish off the perennial ice.

Global Cooling: Amazing pictures of countries joining Britain in the big freeze

From UK Daily Mail – February 21, 2008

Excerpt: In light of such similar news from so many places round the world, it may not seem surprising that U.S. satellite data for January shows the extent of snow cover in the northern hemisphere as reaching its highest level since 1966, 42 years ago - and that temperatures were lower than their average for the whole of the 20th century. Furthermore, it is not only in the northern hemisphere that records are being broken. Following last year's freak snowfalls in such southern cities as Buenos Aires and Sydney, satellite observations from the other end of the world have this winter shown ice cover round the Antarctic at easily its greatest extent for this time of year since data began in 1979, 30per cent above average. […] Global warming "sceptics", on the other hand, are inevitably pointing to these record snowfalls as evidence that global temperatures are no longer rising as the CO2 theory predicts. We may, they suggest, be seeing the start of a period when temperatures reverse their generally upward trend over the past 30 years, as we did in those decades before 1978 known to climate scientists as "the Little Cooling". […] The truth is that it is still much too early to draw any long-term conclusions from 2008's great freeze. But it is one of the most startling developments to have emerged in the world's weather patterns for a long time - not least in that it was so unexpected. At least it raises important questions over how our global climate is evolving which the scientists will have to try to explain. To the millions of people whose lives have been seriously disrupted by this year's freeze, the concept of global warming must seem awfully remote.

Increased snowfall can be an indicator of warming climates, as it is in eastern Ontario. Open waters are subject to more evaporation than frozen ones, and the air takes up more moisture.
