1233884 2011-09-28 10:36:00 The reason "everyone's calling it climate change now" (in fact they're not) is that global warming is the cause and climate change is the effect, and it's the effect that is our problem.

The "myth" of CO2 as a pollutant is semantic babble. A pollutant is an undesirable constituent - the concern is not that there is CO2 in the atmosphere but that there is too much CO2 in the atmosphere. And "too much" means enough to cause adverse effects for the human species, and, as it happens, many other species as well.

1233885 2011-09-28 14:14:00 Lets blame the US army for global warming. Very informed argument there.

A fighter jet with an after burner will consume about 2x the fuel than a jumbo jet at takeoff.
M1 Abrams uses about 5x more fuel than a truck of the same weight.

Following which, I don't believe they have emission testing etc, like your average truck or passenger vehicle...

I would say the US army pumps out more pollutants/ozone-killing crap in a day than all the non-commercial in NZ in a month!

1233886 2011-09-28 18:38:00 SO imagine..... in 40 years of paying carbon tax, nobody remembers this time of why it was even brought in in the first place but we just pay it.... and the climate is no different than it is now. Will they finally admit they were wrong? Gobe1 (6290)

But isn’t there the same amount of Co2 in the atmosphere as there has always been? :confused:

i.e. a miserable 0.03% :D

Err... mate, where have you been all this time? It was at 280 parts per million up to about 1800 AD, and it is currently at about 385 parts per million.

That 280 ppm is enough to keep the mean temperature of the earth about 33 degrees higher than it would be without the greenhouse warming.

and it has been over a thousand in the past so I'm not going to crap myself.

But you might well have done if you had been around then.

What exactly is your point? CO2 levels were high in the past and we know what happened. We are pushing them up high now, so why should the consequences be any different?

You might like to enlighten me as to what the drastic consequence were when it was so high.
