Record high temps in the Arctic create an escalating problem

As if warming temperatures in the Arctic don’t lead to enough problems.

E.g., The record high fall temperatures cause the water temperature to rise.

The sea ice melts.

The Arctic ocean becomes less salty.

Reindeer herds are apparently in decline (“Santa - with only 68 shopping days to go before Christmas!”)

As well as the above problems (‘largely a result of human activities adding carbon dioxide and other heat-trapping gases to the atmosphere’ - link to news article) there is another big problem to consider.


This from The London Free Press:

Rising temperatures help melt the ice, which in turn allows more solar heating of the ocean.

So, as the ice disappears the warming trend occurs faster.

I think climate instability and global warming are occurring fast enough already.

And on a related note re ‘other heat-trapping gases’ and climate instability, this from The Little Green Handbook (see Read This in margin):

“...we release so many pollutants into the atmosphere. For instance, a mysterious new pollutant (trifluoromethyl sulphur pentaflouride) has been identified recently that turns out to be 18,000 times more efficient in trapping solar energy than carbon dioxide. This pollutant has a long lifetime.”

Isn't that another problem too?
