I
couldn’t think of a worse thing to happen as the ice melts, if I
tried.
7.7 ft.- high Waves Set To Batter Arctic Ocean
6
June, 2017
High
temperatures hit Pakistan end May 2017. The image below shows
readings as high as 51.1°C or 123.9°F on May 27, 2017 (at
green circle).
As the image below shows, sea temperature was as high as 32.6°C or 90.6°F on May 28, 2017 (at the green circle), 1.8°C or 3.2°F warmer than 1981-2011.
High temperatures over land and at the sea surface reflect an atmosphere that contains huge amounts of energy. On May 27, 2017, the Convective Available Potential Energy (CAPE) was predicted to be as high as 6976 J/kg at the location in the United States marked by the green circle. Storms subsequently hit a large part of the United States, with baseball-sized hail reported in the Kansas area.
Storms look also set to hit the Arctic Ocean over the next few months.
Waves
as high as 2.34 m or 7.7 ft are forecast to hit the Arctic Ocean on
June 8, 2017, at the location marked by the green circle.
How is it possible for waves to get that high in a part of the Arctic Ocean that is surrounded by continents that act as shields against winds?
On June 8, 2017, temperatures are forecast to be as high as 40.6°C or 105.2°F near Phoenix, Arizona, and as high as 26.0°C or 78.7°F in Alaska, as the image below shows.

The image below shows that on June 6, 2017, temperatures on the coast of Hudson Bay (green circle) were as high as 31.6°C or 89°F.
Four cyclones are visible on the above image.

The
image on the right shows the Jet Stream on June 6, 2017. As
temperatures over the Arctic rise faster than they do at the
Equator, the jet stream becomes more wavy, and where loops extend
over the Arctic Ocean, they can bring strong winds and higher
temperatures into the Arctic.
Winds are particularly strong over oceans and, as the Atlantic Ocean is warming up, those winds can push more warm water into the Arctic Ocean, as discussed in an earlier post.
Furthermore, high temperatures on land are warming up the Arctic Ocean in a number of ways:
• Warm air can get blown from the land over the Arctic Ocean.

•
High
temperatures on land can strongly warm up water of rivers flowing
into the Arctic Ocean.
• Rising temperatures in the Arctic are causing wind patterns to change, in particular the jet stream.
The image on the right illustrates this, showing a forecast for the jet stream for June 8, 2017.
Instead of circumnavigating Earth in a straight and narrow band that keeps the cold air over the Arctic separate from warmer temperatures south of the jet stream, a more wavy jet stream enables more warm air to flow into the Arctic and more cold air to leave the Arctic.
Furthermore, strong winds can cause high waves and these waves can break up the sea ice, mix warmer water all the way down to the seafloor, and destabilize hydrates that can contain huge amounts of methane.
The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.
