On climate change: It's not whether we're hot or cold

One more time, it's important to point out, it's not whether you or I are cold or hot here on any given day.  It's the arctic ice caps and glaciers.  It's this stuff:

Washing Away The Arctic Coastline

Two-thirds of the Arctic coastline is made of permafrost — an environment that is very sensitive to warming temperatures. A new report says erosion is causing these coastline regions to recede by an average of 1.5 feet per year.


Unlike rock shoreline, permafrost loses its structure when it warms above freezing. "Surface air temperatures have reached record levels over the past decade," the report from an international consortium found. Combine this with weakened permafrost and there's a recipe for erosion.



Heightened temperatures have also melted sea ice; with this gone, wind can whip up stronger waves that are able to erode the softened Arctic coastline.
Researchers studied more than 62,000 miles of Arctic coast and analyzed climate data. Northwestern Canada and Northeastern Russia showed the largest changes: Coastlines there have receded by as much as 25 feet per year. Researchers say these changes will have a major impact on arctic ecosystems.
It's these kinds of things, ladies and gentlemen.  It's not whether we had a particularly cold, snowy and/or icy winter.  That and the fact that, for another example, last year was the warmest on this planet ever.  It's that kind of hard data.

So heads up, folks.  Things are changing.  The way we exist on this planet isn't sustainable.
