That's not science.

Well, not sure how much you know about science, but I'm a scientist by
trade - not in climatology certainly, but a lot of science is about
assessing data and probabilities in general. Scientists are by nature
cautious and it's difficult to kick the habit of writing with too many
qualifications. I'd never be able to turn out the concise prose demanded
of a Fleet St reporter :-( Another second career possibility bites the dust!

I'm not sure what your scale of 'human timescale', although timescales
seem to be somewhat of a moving feast in the CC/GW industry. And it's
unscientific.

Slightly odd point to raise, but no matter. UK life expectancy is
currently around 80 years, but I'd guess that for someone born today
improvements in healthcare by eg 2100 might raise that to 100 years. So
for a newborn plus a couple of generations of offspring then let's say
150 years. But the obvious point is that the human timescale is around
100-200 years including eg family memories (my grandad told me what it
was like when...), but not thousands or millions of years.

And 'unscientific'??? You'd need to explain that one.


Weather isn't climate.

Hold the front page!

You want to talk about science, well, here's some for you.

The Vostok ice cores showed that CO2 levels *lag* temperature levels
rather than leading them, over a time span of some hundreds of thousands
of years.

That's quite an old chestnut now. See eg:
