The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

Following Twemoran advice, I wrote to all London MEP (8 representatives) a little more than 2 weeks ago, summarizing the impact of the Arctic amplification (on permafrost, methane hydrate and Greenland ice sheet) and the impact on NH climate with the slowing down of the jet stream and more extreme weather (+ further down the line potential issue on food security) I also attached the «Weird winter mad March Part 2» video with extract of numerous scientists of which Jeff Masters and J. Francis to illustrate the impact on NH climate.

LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was releasing more heat / was accumulating - > radiating + spreading more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation of dry heat and evaporating extra water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting more ice on arctic also as chain reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the evaporation deficit.

Or Arctic sea ice loss could lead to an increase of snow on high - latitude land, which in turn impacts the jet stream resulting in cold Eurasian and North American winters.

Most of the speed is the result of basal sliding, so the ice stream is not unlike a rigid plug, punching its way through the much slower ice on its flanks.

In an article on September 12, I reported on a 2012 paper by Jennifer Francis of Rutgers University and Stephen Vavrus of the University of Wisconsin, which showed that the loss of Arctic summer sea ice cover is adding enough heat to the ocean and atmosphere that it is helping to redirect the jet stream — the fast - moving high - altitude river of air that steers storm systems across the northern hemisphere.

Using satellite and field work after an extreme melt event in Greenland, a UCLA - led study finds that melt - prone areas on its ice sheet develop a remarkably efficient drainage system of stunning blue streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean.

So it's possible that shrinking sea ice in the Arctic could increase snowfall over Siberia, pushing the jet stream southward, creating summer high pressures in Europe that allow India's monsoon rains to linger, and on it goes... It's hard to examine those connections in the real world, but it's much easier to see how things play out in a climate model.
