Of course by that time it will be too late to do anything about it...

As far as I can see, the scientists are pushing extrapolation to the limits (whether it be looking back OR forwards.)
There just isn't enough hard evidence on past climate to allow future climate to be predicted. |
Tree ring evidence? Ice Cores? Layers of ocean sediment? There seems to be a fair bit of hard evidence from where I'm looking.

They even struggle to manage a 5-day forecast, so what chance they'll get anything this far in the future anywhere near right?

This is disingenuous. It's not a matter of whether it will rain over your house next Friday, it's the effect on the whole system.

Which is not an argument for doing nothing.
[quote]One of the problems is that we have no idea of knowing how the climate would have developed over the last 150 years if we hadn't had our input to it.
Which is also not an argument for doing nothing!

And no doubt the scientists of this future era will be just as baffled by the 'evidence' they find as current scientists are by what they've found.

Or maybe they'll think "these people had the chance to at least *try* to do something. Why the hell didn't they...?"
