I've shown you the data. Go to the NSDIC website. I showed you the graph for April, check out the others. In every single month of the year the regression line slants down. They've been collecting satellite data since 1979. They're not making this up just so they can raise your taxes.
TB, I really don't need to win this argument. I don't have a personal stake in it, but you do. We may have our first ice-free Arctic summer before the middle of this century. Not in our lifetime, but in your kids' lifetime for sure.
