Climate Science: Roger Pielke Sr. Research Group Weblog » Iceberg Spotted from New Zealand Shore: "This observation is interesting in light of the below average sea surface temperatures that are currently observed in the Southern Hemisphere high latitudes (see). In the November 17 2006 analysis, the cold anomalies extend north to the South Island of New Zealand.
The news article makes the standard comment on whether or not this event is related to global warming. The more appropriate climate science question, however, is whether the geographic distribution of icebergs in both hemispheres have changed over the last several decades, and, if so, why? In the case of this event, it appears that colder than average ocean conditions in this region are part of the explanation.
The question to the media is why hasn’t this rare (but cold) climate event (and last year’s sightings in New Zealand) been reported more widely?"
