Temperatures in the Arctic are predicted to rise nearly 50 degrees above normal from Thursday under the spell of a pre-Christmas heat wave. It means the frozen tundra is racing close to a melting point. The surging warmth in the past two months has already left scientists jittery, as escalating temperatures are feared to hit ice formation or coverage next summer and bring it down to record low levels. More warming trends are hitting the region as a result of climate change effects.
Walt Meier, a NASA scientist at the Goddard Space Flight Center, said the current warmth is an offshoot of fluctuations in the jet stream that is passing frigid air to North America and parts of the Arctic.
