We know from simple on-the-ground knowledge that the 2010 drought was extreme, leading to record lows on some major rivers in the Amazon region and an upsurge in the number of forest fires. Preliminary analyses suggest that the 2010 drought was more widespread and severe than the 2005 event. The 2005 drought was identified as a 1-in-100 year type event.

That’s from an email to CP by forest scientist Simon Lewis, a leading expert on the Amazon (see Scientists: “There are multiple, consistent lines of evidence from ground-based studies published in the peer-reviewed literature that Amazon forests are, indeed, very susceptible to drought stress”). The figure above is from the University College London Global Drought Monitor via a post by WWF’s Nick Sundt, that I am reposting below.  It represents a 1-month assessment period, through 16 October 2010.
