Iceberg takes on global warming

Of course, satellite coverage is so recent that we have no reasonable historical baseline for how long it takes for an iceberg to reach Macquarie Island:
Australian Antarctic Division researchers working on Macquarie Island, about 930 miles southeast of Tasmania, first saw the iceberg last Thursday [November 5, 2009] about 5 miles off the northwest

I hear rumours the world has been getting colder for over a decade, just not in the right places. Is anyone actually talking about this in the USA?

No. The 2004 NASA simulation extrapolating empirical trends, documenting that increasing CO2 concentration in the troposphere (weather zone) both reduces stratospheric temperatures in the jet stream regime and generally intensifies the jet stream has been rather solidly suppressed.

I would be very unsurprised if average temperatures in parts of India were going down. The particulate pollution from biofuels is so extreme that it was measurably disrupting the monsoons as far back as 2003. (The reporting on MSNBC was weak, so I'm not clear what "reduction of sunlight intensity at ground level by 20%" means when the reference intensity reduction from free space to ground level is from ~1366W to ~1050W i.e. ~23.1%. )

The short answer would be that it is almost a quarter the length of the whole British Isles. Sounds like it deserves to have generated its own micro climate!
