This is a storify of the twitter noise around one talk at a Royal Society discussion meeting.

This post is quite long but stay with it. It shows how large some of the heat exchanges going on in the polar oceans can be.
The picture above shows an iceberg through mist rising from the sea.
It is pretty, but it is also showing is a vast heat flux of hundreds of watts per m2 from the ocean to the atmosphere...
I have talked before on this blog about how the sea ice moves, and how the International Arctic Buoy Programme provide some lovely movies of the buoy tracks which show this. I also pointed to Eric Larsen's video of the ice moving too.
But what does this ice movement mean for the climate?
As the ice moves it fractures, and the cracks extend over wide areas. These cracks are responsible for the "water sky" I talked about previously.
From the scale bar on the bottom left you can see that the open water is ~18 km wide, and the lead is more than 100 km long. More than enough to get a ship through!
In March 2013 I was delighted to be asked to give a talk at TEDx Southampton.
This is what I talked about: What the poles are telling us about our world
It was brilliant to be asked to speak, and really enjoyed the fantastically well organized day. Many thanks to the hardworking large team who put it together, and in particularly James Dyke,Alison Simmance and Jonathan Akass.
On the TEDx Southampton YouTube channel for the event are some amazing talks from that day.
It's a little odd to me when people refer to the polar regions as being something to do with the "sounds of silence". I have never thought of peace and quiet when I am on sea ice. You see the sea ice is always moving, (except when it is frozen to the coast and then we term it "fast ice"), and when it moves - the individual floes are constantly colliding and banging into each other. The collisions and banging can be very noisy.
Samuel Taylor Coleridge knew that when he wrote the The Rime of the Ancient Mariner in 1798.

Back in July 2012 the global news media went very big on a story on the Melting of Greenland.
I got involved in a discussion on twitter about it, with lots of context and decided to have a go at seeing if I could put together a “storyify” on it using the contributions of a wide range of outstanding climate scientists.
This morning I posted my 10,000 tweet.
Whilst I am not sure if 10,000 is significant, I pointed to the brilliant NASA Earth Observation www site which has a wonderful post today about the reduction of sea ice increasing phytoplankton growth in the Arctic. (Be sure to click the "image comparision" button on that page).
