I still get deniers telling me there is no evidence for the effects of co2 on the atmosphere.
But in fact, the properties of co2 can be demonstrated with the simplest of tools.

1. That crock of the week series is excellent.

But grammar school experiments may be a little over the head of some of the right wingers

2. Proving scientific theory with the 'simplest of tools' is lost on the simplest of fools.

4. I'm so thankful for these videos K+R every time!

So simple to understand.

5. Kicked and recommended.

Thanks for the thread, greenman.:thumbsup:

6. So, according to Dr. Tans, CO2 can hide us from Predators.

7. Ok, here's the deniers' argument: all the infrared CO2 can absorb is absorbed in the first 10 meters

of the atmosphere. Therefore, adding more CO2 will have no effect, except to lower that absorption point to 9 meters.

Think about it for a bit. Can you see the flaw?

Here it is: The atmosphere is not freezing cold 11 meters up. The atmosphere is still warmed by a greenhouse effect several kilometers up. Why? Because CO2 absorption of infrared is only part of the story. Conduction, convection, and re-radiation complicate it. It turns out, adding CO2 matters at the top of the troposphere.

From 1900 to about 1938, the deniers' theory was generally accepted by scientists. Then someone tried to model the atmosphere in layers, taking all the factors he could into account. By hand, he could only do enough arithmetical calculations to divide the atmosphere into 12 layers. Computers refined the models into many more layers over time, but the basic results remained the same--CO2 concentrations at the top of the troposphere make the difference.

8. Thanks - for the deniers theory -

here is the response - if you have a solid un-moving heat sink - a piece of steel -
and apply heat to it it will continue to absorb heat all the way through -
the only way any part will remain cool further away through dissipation.

So it makes no difference, the heat is continually transferred and dispersed throughout the object - atmosphere.
The dissipation from the steel is out of the steel into the surrounding atmosphere.

When I heat a pot of water - the bottom 1% is not the only part which heats up - even before convection occurs it is dissipating into
the surrounding water and the pot itself - and then into the atmosphere.

The argument is simply absurd.

The effects of C02 as a heat trapping agent were first discovered in 1850's - and confirmed shortly there after.

Videos like this are about as intelligent as showing the combustive effects of fire in air - truly mind boggling that
something this accepted and mundane needs to be even explained.

We discovered that the earth revolves around the sun a long time ago - the fact someone needs a kid to show that process is insane.

10. the interesting thing is

I'm getting a ton of responses to the vid.
Taking things down to the very lowest common denominator -
6th grade science project - seems to be a winner.
Not that everyone's convinced. Still some
very thick stupid out there.

9. This is a COTW even teabaggers can understand-

if you can get them to stop shouting long enough to watch it, that is.
