    I have it on good authority that we'll all be dead by 2030. So why bother?

    Start working at home with Google! It's by-far the best job I've had. Last Wednesday I got a brand new BMW since getting a check for $6474 this - 4 weeks past. I began this 8-months ago and immediately was bringing home at least $77 per hour. I work through this link, go to Economy tab for more detail ...

    Bottom line it for me, is this global warming thing going to bring about a Mad Max type scenario? Because I don't think I have enough armor plating for my muscle car.

    Where have you been? There's a government shutdown going on. Right now. If your Mustang 5.0 doesn't have armor plating on it now, it's too late.

    How do the data compare to the models?

    I wish these scientists would just cut to the chase and tell us when civilization will collapse. If they can tell us what the weather's going to be in 200 years, surely they can tell us that.

    No offense, but nobody gives a flying fuck about a monthly temperature report. We are galactic beings thinking in cosmic time frames. Ohh shit, I hit the "preview" button, what happens now? Rabid squirrels?
