Look Twice At Climate Change Data

There has recently been some discussion, already mentioned in ‘The Observatory,’ about a finding that the Greenland Ice Cap and part of the Antarctic Ice Cap are not melting as fast as once suggested. The conclusion was based on a new method of analysing data from the pair of GRACE gravity measuring satellites. However, it is a good example of how a simple conclusion can enter the climate change debate and be accepted as a fact when a closer look at the data shows much uncertainty. It illustrates that standing back and looking at the bigger picture, often reveals something quite different.

According to the new paper by Wu et al (2010) published in Nature Geoscience the Greenland and West Antarctic ice caps are melting at half the rate previously measured.
