Climate Change = Loss Of Ice In The Arctic = Snow In Jerusalem

They are all connected.  

Here are the numbers on the loss of arctic ice:

Here is Phil Plait's commentary:

This melting ice can indirectly cause weirder weather. As the ice melts, more ocean surface is exposed to the Sun, warming it further. Moreover, as more fresh water is dumped into the salty ocean from the polar ice, the currents in that water change, bringing with them different temperatures to different places. The flow of the jet stream over the pole depends on temperature, and that can change as the temperature changes. You see bigger dips in the stream, bringing cold weather south, and warm weather north. This can also create what are called blocking patterns; high pressure systems that block the normal movement of air, creating stagnant conditions over a region. Alaska’s heat wave over the summer was one from one such blocking pattern, as was Greenland’s last year. A vicious cold snap in the US in March 2013 was also due to such an event.

Also directly related to this is the extreme cold in Connecticut this morning, and this:
