So let me get this straight...it has been admittedly thinning for "millenia", yet the New Zealand Herald with it's thousands of years of observing history has determined that it was an almost immeasurable temperature change in the last 50 years that caused this ice shelf to collapse? How arrogant and short-sighted can you get? Just because we haven't SEEN something happen in the perhaps 30 years that we would have been able to observe such an event, how can one presume to chalk it up as a cataclysmic event in the history of the planet? The leap (or lack) of rational thinking there is just stunning...
Next it'll be Karl Rove's fault that we can't walk from Alaska to Russia anymore...
