(Source: NASA)Arctic winter warming events, winter days when temperatures peak above minus 10 degrees Celsius, are becoming more frequent and lasting longer than they did three decades ago, a new research has found. The study, published in the journal Geophysical Research Letters, showed that since 1980, an additional six warming events are occurring each winter in the North Pole region. Because autumn and winter is when Arctic sea ice grows and thickens, warmer winter air temperatures will further impede ice growth and expansion, accelerating the effects of global warming in the Arctic. The findings build on other recent evidence of Arctic winter warming. The winter of 2015-2016, for example, saw temperatures nearly 2 degrees Celsius warmer than the previous record high monthly winter temperature.
