Polar front.... not ideal...

The Polar front is the controlling factor on our climate. The meeting of cold Polar air with temperate mid-latitude air (or sometimes warm Tropical air) produces waves which lead to the development of mid-latitude depressions.
The position of the front is influenced by the jet stream, but also the state of the oceans - and the oceans are losing their ice.

Could we be seeing irreversible change in the Arctic region?
