There are Monsters in the Ocean.

Today a large storm has been battering the north of the UK, I've been stuck at work, but I just couldn't stop myself checking up on one buoy in particular.

Global and UK Temperatures 2014: New Records?

The BBC are reporting that this year looks set to be the warmest year across the globe and here in the UK. Although I mainly concentrate on the Arctic and sea ice, I couldn't do that without being all too aware of anthropogenic global warming, so here goes...

The Slow Transition: Trendsetters.

Statistical extrapolation of volume loss has been used to make the claim that the Arctic sea ice faces a rapid decline to a state of summer open water within a few years, or at least this decade. Is this technique likely to give expectations that will be disappointed?

Mid November Status

Rather than just do a PIOMAS post, this post presents a few reflections on ice state in October as the refreeze progresses using various sources.

The Fast Transition



The peripheral seas of the Arctic Ocean are now virtually ice free in September, they are seasonal sea ice seas.

Need I say more?



It seems I do...

In comments Oale wanted to see this in terms of area, which is fair enough. I've done two graphs, one for area one for extent, both with a plot as percentage of April area and extent.

PIOMAS September 2014: Massive Volume Gain

The story of the 2014 melt season has been one of unexpected ice survival due to weather being largely unfavourable for largescale ice melt. Now, after a delay to NCEP/NCAR reanalysis data, the PIOMAS volume data is out and it is possible to see how much volume gain will be carried over into the 2014/15 winter, and very likely beyond.
