A Guardian piece titled: Climate scientists withdraw journal claims of rising sea levels in the current climate debate might lead you to think that overstated claims by climate scientists have had to be retracted. But this could not be further from the truth, instead the scientists have been too conservative with their estimates of sea level rise. Previous estimates of sea level rise have proved to underestimate badly the potential sea level rise. The previous maximum estimate of sea level rise by 2100 of 82 cm is now closer to the new minimum estimate of likely sea level rise by the year 2100.
This is a consequence of the attacks on climate scientists and their attempts to cover their asses not by keeping strictly to what the science says but instead by taking the science and reporting only the more conservative of future estimates of change.
Gravity measurements by satellites is demonstrating that ice loss in Antarctica and Greenland is happening faster than expected and that the melting is rapidly accelerating.
You can see how the denialosphere has run with this headline and taken it to mean what they want it to mean. In this case I use the term denial and not sceptic, because they have once again taken the article headline out of context, interpreting it in a way that nicely fits their world view without any sign of scepticism whatsoever.
