Several weeks after the Christmas Arctic blast, much of the US and Europe have enjoyed record warmth. Recall on Dec. 27, we noted the cold air mass from Siberia that spread across the continental US would dissipate into the new year. So far, this is correct, as three weeks of above-average weather has staved off an energy crisis in the Northern Hemisphere. But just north, in Siberia, temperatures are sinking to near-record lows. And it could only be a matter of time before the giant cold air mass swirling in the North Pole becomes unstable, breaks down, and begins pouring into the US and Europe. Global warming alarmists who called for an imminent climate disaster last summer are scratching their heads as the rural northern Siberian town of Zhilinda just recorded temperatures of minus-79.8 degrees, according to climatologist Maximiliano Herrera, who tracks extreme temperatures across the globe.
