Tim Curtin insists on topping himself.....

Not only does he start by blowing two orders of magnitude in his favor....

Industrial production of CO2 at 100 million tonnes in 2005 growing at 10% pa (your figure) will overtake fossil fuel emissions of 25 billion tonnes of CO2 growing at net 0.005% pa (the actual rate of growth of CO2 at Mt Louai in Hawaii) by 2067.fossil fuel emissions of 25 billion tonnes of CO2 growing at net 0.005% pa (the actual rate of growth of CO2 at Mt Louai in Hawaii) by 2067

Only to catch himself half an hour later

Re Eli again, a correction, I mistyped the CO2 growth rate at the Hawaii station, it is 0.5% p.a. ( which is what I used in my extrapolation). Apologies.

But he can't figure out how to spell Mauna Loa (nice picture here).

He can't figure out that when the hare of the day (Happy Easter to all) said:

Yes, if you have one buck to your name and your money grows by 10%, while Bill Gates' money grows by 5%, your money is growing faster than his. And at the end of the day you got $1.10, and he got several hundreds of million $ in extra interest.

The 10% rate of increase did not refer to the growth of CO2 production for industrial gases. That looks to be ~3% or so (at least in the US).

As Chris O'Neill pointed out on Deltoid II even the correction is a bit shifty

BTW, the atmospheric CO2 is growing at 2% of the atmosphere's anthropogenic CO2 per year. If you want to model atmospheric CO2 with an exponential growth curve, try to remember that it didn't start at zero as an exponential growth curve does.

But wait, there is more, on an absolute basis, the rate of increase is closer to 0.7% than 0.5% (2.6 ppm/381 ppm current) and if you look at it as a percentage of preindustrial (280 ppm), then it is close to 1%.

Ian Gould is starting to make the point that most of the CO2 used for industrial purposes, ends up, guess where, in the atmosphere......

However there is another important question to ASK Tim Curtin: Where did that 100 million ton figure from, and in what sense it is using production. A lot of CO2 is produced in various industrial processes (brewing beer being my favorite) but very little of it is captured for industrial purposes.

Stephen Berg ASKS an important question:

Why are we squabbling over such a minor detail when there is a lot of work to be done to save our planet from ecological catastrophe?

To which the obvious answer is that when folk like Tim Curtin start throwing sand in the air, you need to show their propaganda up for what it is so that folk like Stephen Berg will see them for what they are, and what they are is not making any kind of contribution to an honest discussion.

Off to deliver......
