Did you ever stop to think about what kind of massaging you need to do to temperature readings to measure global temperature in half-degree units?

There are many methods of attempting to calculate old temperatures without the benefit of actual measurements onsite. Ice cores are one. Tree rings, another. Some scientists use calcium deposits in shells.

What you're looking at in my graph is actual temperatures. That's what they do over time.

We don't know how much of the current trend is natural cycles, and how much is related to human activity. It's obvious that natural cycles exist at these ranges. Ice core data going back hundreds of thousands of years show even larger ones.

In the southern oceans, the Antarctic sea ice is steadily expanding. Why? A lot of questions need answering before we blow our industrial civilization to hell.

I understand these people are slavering to take control of all industrial activity on a planetary scale, and tax the living shit out of it all (re: James Hansen), but maybe it's a little soon.

Ever notice that solutions that don't involve statism aren't even put on the table? The same people (not all of them, to be fair) who scream the loudest about emissions also can't stand the ideas of nuclear and hydroelectric power, and as we've seen recently, they don't think that much of big solar plants either.

Again, the "hostility" is a natural suspicion of people who address every issue, not just this one, with the hammer of powerful centralized authority and wealth confiscation. If McDonalds claimed their french fries were the cure for all known diseases, wouldn't you be just a little skeptical?
