A study shows the progressive reduction of Arctic sea frost
is bringing colder, snowier winters to the UK and other areas of Europe, North
America and China. It's possible that future winters will be colder and
snowier, but there are some qualms. But less of the sea is frozen in autumn, it
releases more heat, warming the environment. In turn, this reduces the power of
the northern jet stream, which usually brings milder, wetter weather to Europe
from the west.
Dr Scaife was concerned with another learning published last
year that showed how small, normal changes in the Sun's output can also affect
winter climate. The novel study is not the first to propose a causal
relationship between low Arctic ice in autumn and Europe's winter weather. The
researchers also found that the extra evaporation from the Arctic Ocean makes
the air more humid, with some of the additional water content falling out as
snow.
