Actual Carbon Emissions vs. IPCC Scenarios - how far away is safety?

30. The point is to present what is possibly the worst case scenario imaginable.

And to make the point that it's based entirely on our current behaviour. The point of this is to shock people, not to give them hope.

Yes, our behaviour will change as circumstances change, as it always does.

the point is that we have no way of knowing at this point how circumstances will change, so rather than get into that bunfight I present the consequences of our demonstrated current behaviour. Think of it as a baseline. The main point is to show just how far our baseline is from what the behaviour necessary to meet even a minimally effective IPCC scenario.

I'm working on a new set of graphs that will incorporate three starting points for emissions (1980, 1985 and 1990) and show the ultimate CO2 and temperature consequences for each. Watch this space.
