Limit the conversation to atmospheric carbon dioxide.

The carbon dioxide in the atmosphere has almost doubled since the industrial revolution. Since the 60s alone, we've gone from 320 to 420 PPM. The entire sharp increase not only maps onto the industrial revolution, but is also entirely predictable: we are taking carbon which is sequestered in petroleum and coal from the ground, and releasing it into the atmosphere.
There has been a very predictable cycle of increases and decreases in carbon dioxide in the atmosphere over the last million years, and we're well above the cycle's previous highs.
That's it, IMO. Avoid predictions, avoid associating climate events to it, just focus on CO2. Isn't it surprising by how much we've increased the atmospheric CO2? Shouldn't we be hesitant to shift planetary scale atmospheric composition on such orders of magnitude, and confident in our abilities to have access to energy that doesn't continue to move carbon from the ground into the atmosphere? Wouldn't it also be useful to focus on technologies that allow us to move carbon out of the atmosphere?
