4. Does Plan B make the problem worse?

Shouldn’t we address its root cause? Well, yes, we certainly should have, decades ago.

Unfortunately, I’m afraid it is too late to address the root cause.

We’re looking at 400 ppm of CO[font size="1"]₂[/font] and rising.

Hansen and co suggested that we need to lower it, “to a level of 350 ppm or lower.”

Now, how are we going to do that in a timely manner? (Hansen and co. also warned, “If the present overshoot of this target CO[font size="1"]₂[/font] is not brief, there is a possibility of seeding irreversible catastrophic effects.”) If we stop all emissions tomorrow (based on ice core data) the levels may return to 350 ppm in as few as 50,000 years.


Recent discoveries tell us that the last time CO[font size="1"]₂[/font] levels were about this high, temperatures in the Arctic were about 8°C warmer than today.

This tells me that we will need to find some artificial means of capturing and sequestering GHG’s.
