Get it straight.

Oh, and about the polar ice caps melting and creating floods or rising oceans:

Tell the idiot who screams that one at you, or better yet show them:

Fill a glass with ice.

Fill the rest of the glass to the brim with water.

Let the ice melt.

Notice something?

Does the glass overrun with water?

Not that a rise of 1 degree C could melt the icecaps anyway, a science experiment we shall save for another day.

Now, about CO2.

Our Earth’s atmosphere contains aprox. 380 some parts per million of CO2.

Let’s give algore the benefit of the doubt and round it off to 500 parts per million, just to make the math easier.

500 parts per million.

1 million divided by 500 = 2,000

Reciprocal to get the decimal: 0.0005 or five ten thousandths of the atmosphere would be CO2 at most.

Next time, we’ll demonstrate how and why CO2 in its gaseous state cannot reflect any significant amount of radiant energy.

1st and 2nd laws of thermodynamics apply.

Back in the day, we had to learn those two laws to pass High School Physics.

Which was in the sophomore or junior year, no less.
