he doesn't have one.
he has an opinion, but he can't justify it, except by saying that really, really smart people told him so and they know everything, so there! he doesn't even have the slightest idea how "temperature anomoly" is determined or what it means. he just sees a graph of a couple hundred years(which is a sample size of NOTHING in geological terms) that rises an assumes disaster. yes, if the temperature rises and never stops rising, we're doomed. fortunately, the real world doesn't work that way. maybe i'll make a fake graph to counter his fake graph.
ultimately, i think his real agenda in reposting that silly jpeg is to destroy all conversation that relates to the topic at hand, that th University of East Anglia, the compiler of the data which the whole world is using to prove man-made CO2 global warming, was caught red-handed fabricating that data. he acts like he has a stake in the farce, instead of someone who is most concerned with finding the truth. perhaps it has someting to do with government housing...

ok, sorry, bc, but you're pretty fiesty with that fake graph of yours with it's ridiculous "temperature anomoly" axis...
