Using gravity measurement data from the NASA/German Aerospace Center's Gravity Recovery and Climate Experiment (GRACE) mission, a team of scientists from the University of Texas at Austin has found that the East Antarctic ice sheet-home to about 90 percent of Earth's solid fresh water and previously considered stable-may have begun to lose ice.
The team used Grace data to estimate Antarctica's ice mass between 2002 and 2009. Their results, published Nov. 22 in the journal
Nature Geoscience, found that the East Antarctic ice sheet is losing mass, mostly in coastal regions, at an estimated rate of 57 gigatonnes a year. A gigatonne is one billion metric tons, or more than 2.2 trillion pounds. The ice loss there may have begun as early as 2006. The study also confirmed previous results showing that West Antarctica is losing about 132 gigatonnes of ice per year.
"While we are seeing a trend of accelerating ice loss in Antarctica, we had considered East Antarctica to be inviolate," said lead author and Senior Research Scientist Jianli Chen of the university's Center for Space Research. "But if it is losing mass, as our data indicate, it may be an indication the state of East Antarctica has changed. Since it's the biggest ice sheet on Earth, ice loss there can have a large impact on global sea level rise in the future."
Comment: If Monbiot thinks an email will EVER surface that plainly and explicitly reveals the conspiracy to misinform the public about global warming, he needs to retire and drink warm milk.
The aspect of 'conspiracy' revealed by these emails is not a case of some people getting together and saying "Oh, let's have a conspiracy!" Conspiracy in this context simply means that a group of people act in certain ways that they KNOW are dishonest at a fundamental level, and they use what Lobaczewski termed "subconscious selection and substitution of premises" to explain things in their own minds. This is a predominantly subconscious process though it certainly has to be conscious in some respects.
It is definitely a conspiracy where these scientists are concerned because they have all made a decision to support a particular world view that has been "decided before hand, be damned to the data". Sure, there is no widespread conspiracy by all climatologists to cook the data for global warming, but there are a few "top" scientists lacking in conscience that have been leading the "human-made global warming" campaign and have been doing so for at least 10 years.
