Some of the best kept secrets in today's world are not in the CIA, but in climate. For example, I am sure you saw all the news a couple of years ago that Arctic sea ice extent hit an "all-time" low (by all time they mean since 1979 when we had satellites watching the ice). But, did you know that on the exact same day, the Antarctic sea ice hit extent an "all time" high? No?
OK, try this. When people talk about rising oceans, only land ice matters (since sea ice floats, like ice cubes in your drink, their melting has no effect on ocean levels). I am sure you have heard that scientists think that Greenland ice caps, representing 10% of the world's land ice, have melted at record high rates over the last couple of years (yet again, keeping in mind the observation period is only about 30 years). Did you know, though, that during the exact same period, Antarctic land ice representing 89% of the world's land ice has melted at record low rates? No? But the studies are done by the same people who did the Greenland work that were published everywhere.
You see, the press really can keep a secret nowadays.
