Just disagreed with your percentages.

The long-term stable concentration of CO2 in the atmosphere was within a few percentage points of 280 ppm, for almost a million years until about 1850. That is when the Western-civilization industrial revolution started replacing water power with steam generated by burning fossil fuels, first coal, then oil. It is currently about 400 ppm, with human activity the only logical source for the increase. The difference is about 30% of the the current concentration.

Similarly, ancient methane concentrations ranged from 500-700 ppb; it is currently over 1800 ppb. Your assignment is to calculate the difference.

Gobbledegook.
Co2 concentrations have been much higher and lower.
1850 was the end of a significant cold period, which followed a significant warm period, within a larger inter glacial.
3% of .04%

You sound very convinced for someone who isn't a scientist.

We should avoid alarmism, but in reality, who knows what we're really headed for? What if it turns out we took it too lightly and could have done more to avoid a negative result?

Hope for the best, plan for the worst. Actively fighting against the possibility of a dire outcome, because you view AGW as a left/right political battle is silly.

The politicians who say AGW is a left wing conspiracy are fools. Christ, even the military is taking it seriously.

Yes, Obama's military, nut job.

What exactly do you think Im convinced of?
Did you even bother to look up the percentages?

Your ability to draw conclusions based on your scientific knowledge. You're a plumber right?

Why would I bother looking up those percentages, I'm not pretending to be a scientist?

Probably one of the dumbest statements I have seen you make so far....

Obama is the commander in chief. He does control the military and lets not forget NASA, which he redirected to reach out to the muslim world and decimate the astronaut program.
Wake up Wezdumb.

Yes he is commander/chief, but he doesn't direct the day-to-day operations of the Dept. of Defense. I see nothing wrong with his reach out to the Muslim world, we've done little but send bombs and missiles their way for way too long. Here's the part where you talk tough and say we should be attacking them, not reaching out to them...

I am sure the military can't/ won't do anything without his ok, especially if it might offend a radical muslim.
Whos decision do you think it was to have the military to pay for tranny surgery? Or to allow gays/trannys to openly serve in military and be married by a military chaplin? How about women in the infantry? These things are not helping this country.
Your president is a left wing, radical, America hating bastard.

Is this OK?
