- My simple observation is that scientists don't have that kind of data for

- So, you have admitted that you don't have sufficient evidence to justify
- drastic measures. So, why not save the "end of life" hysteria until there
- are enough data to justify it?

- Maybe, but it is also possible that new fuels and power sources may change
- before any of this really happens. No, I don't know what they are. However,
- I do expect technologies to advance in ways we don't expect. There also are
- many other alternatives (e.g. planting lots of trees, etc.)
-
- About your expertise in meterology. I am not questioning your abilities, I
- simply reserve the right to disagree with the results. I'm not an expert in
- your field, but I do know quite a bit about simulations. I know that one
- can change the simulation result quite significantly with seemingly minor
- changes in the input data or the equations used to calculate results. I
- assume that you are doing your best to produce objective, accurate results.
- However, that doesn't necessarily mean that the results will be correct.
- I'm sure that you will admit that this is not an "exact science" yet.
- By the way, do you include a statistically representative set of volcanic
- eruptions in your simulations? (Just curious, I'm not trying to insult
- you here. Answer by EMail if you like.)
