2013 sea ice thread!!!

[ScienceRocks]

All discussion of Arctic sea ice!!! Let's watch the min!!!

So far we're tracking even below last year!

According to the model data 2013 has peaked at a total volume of 21,823 km3 on April 17th, which is 100 km3 below last year's record. Since then, 2013 volume has dipped quite a bit below last year's number (295 km3 to be precise), but is still close to 2011 which has only 63 km3 more at this moment.

Look how wide the max to mins are now...Twice of what they were in the 80's to 1995.

holy shit!

holy shit!

Consider, it takes a lot of heat to melt ice. 334 J/g to be specific. It takes 4.81 J/g to heat water 1 degree C. So when the Arctic ocean was mostly covered by ice for the whole summer, even though the top of that ice was melting, it was absorbing a lot of energy to melt. Not only that, it was also reflecting about 90% of the energy of the sunlight back into space.

Now, there is more open water than ice for part of the summer. So that ice that normally was absorbing 334 J of energy per gram to melt is not there. And the water, when it absorbs that 334 J that would have melted ice, no temperature change, now warms over 67 g of water 1 degree with that 334 J of energy. Not only that, but instead of reflecting 90% of the sunlights energy back into space, it absorbs 90% of that energy. Now that is one honking feedback loop.

Some things to bookmark. First, a higher resolution ice extent map, using data from the recently launched Japanese GCOM-W1 satellite, can be found here:

http://www.iup.uni-bremen.de:8084/ssmis/index.html

Also useful is the US Navy's ice motion map, which shows which way and how fast the ice is drifting. You can see how winds are currently pushing ice out the Fram Strait (east of Greenland).

Finally, the thickness map, also from the dirty socialists at the US Navy.

We're slightly below last year but 2011 is slightly lower at this time....So I'm going to say that we're going to be within the top 3 this year.

This really depends how the weather pattern sets up during the melt season; July-Sept.

This is last years thickness

Ice is melting all around the planet due to global warming and its associated climate changes, and the greatest loss of ice so far has occurred in the Arctic.

It can be hard to get a clear mental picture of just how great the loss of Arctic sea ice has been, but this video does a pretty good job of illustrating the magnitude of that loss.

We're below 2012 through mid April based on thickness. We're slightly below 2012 based on extent too.

I've modeled the maximum since 1980 for thickness. Is it growing earlier in the season??? Like a full month. wow.

Excellent documentary about tracking glacier melting -

That doesn't lead to a documentary about glaciers.

That doesn't lead to a documentary about glaciers. I'll say that isn't a good excuse for a war zone as we should of known it was pretty likely to happen.

Sorry bout that. I clicked to post and then went to feed the dog and cats without looking at it. Here's the real link --

Slow start to the 2013 melt season, due to the last two weeks being cool around Greenland and the Canadian Arctic. That's kept the ice in Hudson Bay and Baffin Bay more or less intact, pushing the area totals up. However, since Baffin Bay and Hudson Bay always melt out completely, it's not going to matter in the long run.

There was a moderate cyclone right on top of the north pole 4 days ago, which you can still see on the Navy wind speed map, as they haven't updated their maps for 4 days. Not sure why.

The more interesting thing for the long term is the above-average temps on the Russian side, leaving the ice on that side of the Arctic basin full of cracks (the lighter purple).

You're clueless of the scope of reality you'd need for you to understand at all. A weather pattern(blocking ridges, lows, etc) are causing that cold and a piss poor melting season in the arctic.

Outside the world of the bubble dwellars exists a world where reality is 95% perception.......and when people are freezing their asses off all over the country when its almost summer, THATS the only important scope of reality!!!


Far left guys just cant connect the dots on that........what can I say?



But go.....go.....go on all the sea ice debate!!!!! Knock yourself out s0n!!!

A medium sized cyclone over the north pole now. That's flinging ice south out the Fram Strait and towards Russia, which is having a warm spell now.

It's also cracking the central ice pack. In the Arctic, there's colder water on top and warmer water below, and such storms draw up the warmer water and cause melting. I haven't seen a map like this before, with the lighter colors in the central ice pack so early in the season. Long term forecasts are for the storm to die down, then several days of warm temps and strong sunlight on the Russian side, then another cyclone.

The Russians move to evacuate their North Pole station as the ice under it cracks. That station was supposed to last until September. Right now, the station has drifted closer to Canada, but the Russians are still handling it, using a big icebreaker that carries helos. If it gets really serious, they'll ask Canada for an assist.

The June 5 forecast for Churchill on Hudson Bay is 23C/73F, and the June 6 forecast is 27C/80F.

Churchill, MB - 7 Day Forecast - Environment Canada

That's going to put a dent in the Hudson Bay sea ice. Significantly above-average temperatures are forecast for the most of Canadian Arctic and Greenland. In addition to sea ice melting, the snowpack on land, already below average, will probably end up totally gone on the continent and majorly reduced on the islands, which sets the stage for more sunlight absorption. The general Arctic forecast is sunny for a few days, then a new cyclone forms around June 10.
