It is the melting of Arctic sea ice that is associated with the harsh cold and snowy winters in the mid-latitudes.
Climate change is not always obvious. Our latest research shows that modern interpretations of climate are oversimplified and oversimplified. We must beware of making sweeping statements about the effects of climate change.

In his work, Hubbard explored a controversial climate paradox: a 50% reduction in Arctic sea ice cover increased open water evaporation and winter evaporation: they now fuel extreme snowfalls in southern Europe.
New work showed that the long-term reduction in Arctic sea ice since the late 1970s had a direct link to the heaviest snowfall in February that same year, which caused a loss of £ 1 billion.
The researchers found that atmospheric steam coming south from the Arctic carries a unique geochemical signature: its source is the warm, open surface of the Barents Sea, the part of the Arctic Ocean between Norway, Russia, and Svalbard. During a massive snowfall in 1970, 88% of the condensed water came from the Barents Sea.
Scientists concluded that sea ice effectively blocks access to the ocean, water does not evaporate, and therefore large winter precipitation is reduced. It may sound counterintuitive, but nature is complex, the authors summarize.
