vague

At some point I need to decide if I'll re-start the by-now-traditional sea ice bet for the summer. Before we start arguing over the details, remember that there is a lot of inter-annual variablity so we need to disagree *a lot* to have a meaningful bet. But at least one person has said in the comments that they feel "worried" by this years ice, so that suggests pessimism that I can exploit! Any thoughts about what you might want to bet about, please leave a comment. My default position is going to be "will fit the 1979-2009 slope extrapolated to 2010". Bear in mind that this isn't a forecast…
