So, because he's a nutter the graph shouldn't be front page news is the argument then? That'll teach him.
He will learn the regret the day he dared say "hey, this graph means we're all gonna die if we don't do something! Look at it!" because we outsmarted him by refusing to look.
Because he's a nutter, you should not take his word for it that a 3.5 sigma event (1 in ~2000 for a normal distribution) in the temperature of a particular ocean region means we're all gonna die if we don't do something.
Well before I knew he was a nutter, it strikes be that the graph starts in 1991. Feels like we should should have more data than that, and that the same graph would be more powerful if it started in 1800 and showed the same thing (or at least, earlier in the 20th century, surely we must have data from the 1950s at least? probably earlier?)
Not saying that the data is not concerning, or that climate warming isn't real, BTW. I'm just saying this particular graph feels fishy.
