Putting ocean warming into perspective | Planet3.0
David Appell spots a nice little calculation in the recently published Levitus 2012 paper on ocean heat content:
We have estimated an increase of 24 x 1022 J representing a volume mean warming of 0.09°C of the 0-2000 m layer of the World Ocean. If this heat were instantly transferred to the lower 10 km of the global atmosphere it would result in a volume mean warming of this atmospheric layer by approximately 36°C (65°F).
A paper published today in the Journal of Climate concludes "that natural variability, rather than long term climate change, dominates the sea surface temperature...changes over the 23 year period" from 1984 to 2006

Of course, the decision to sharply limit the discussion of climate change, despite the fact that the Arctic climate is changing in ways that almost assuredly have a human contribution, could be seen as producing the ultimate slant in the show. This is particularly germane this week, as a couple thousand scientists and others focused on polar change have gathered in Montreal for a large conference (Twitter feed here) reviewing the enormous body of work produced under the recent International Polar Year initiative.

The new paper focuses on local supernova rates (rates of explosions of large stars) and suggests that high rates of explosion could coincide with colder conditions on planet earth. The paper draws a correlation between long-term changes in sea-level and supernova rates and marine biodiversity and productivity over the last 510 million years.

Do we have global warming? No. I think the cooling trend is still in place and the variables are the seasons and precipitation.
