Funnily enough, they arnt!
There would appear to be aspects of "Transition" that take place at the beginning and end of ice ages that happen
very quickly indeed. Ice ages are not well understood at all! (Geologists have historically been scared of sudden large events and have avoided them as explanations as far as possible. They only recently accepted the idea that there were
MASSIVE flash floods in NW USA at the end of the last ice age)

surely the best thing is to minimise our effect on it as much as possible.
True, but this only works if we are taking the right action for ther right reason.
During the black death it was "Common Knowlege" that the plague was casd by Witches. It was also "Common Knowledge" that Cats were Witches familiars and agents of the dark one! As a consequence Cats were rounded up in vast numbers and killed (typically by being tortured to death)
This was, of course, a
BAD move!
The only effective way of reducing Mankinds effect on the enviroment is to reduce the numbers. Us (In the UK) reducing our own consumption of the black stuff (even supposing that an overall reduction in black stuff consumption would make any diference anyway) wil not result in an overall reduction. It will simply be consumed elsewhere.
OPEC is currently declining to increace production in response to the high prices. They claim that they do not believe it is nececarry. Personally I recon that they are actually at their production limit and couldnt produce any more even if they wanted to!
(See
http://dieoff.org/42Countries/42Countries.htm)
Basically black stuff consumption is set to decline dramatically over the next century regardless of what anybody plans.
(Governments will, no doubt, use this factor in order to claim that their "Green Policies" worked! Ho Humm, Where have we seen this before)

Poor analogy, a better one is living in a house called "Clifftop" in dorset.
Do you spend your cash on;
a) Lobbying the UN/going to confernces in Bali
or
b) Tipping rubble on the beech to slow down the erosion and/or moving further inland.
As a nation we need to be doing less of a) and rather more of b)! In particular we need to be aiming to achieve energy/food neutrality. we also need to achive and maintain an independent industrial/scientific/engineering infrastructure.
Added to that, we need more people in these islands like we need collective holes in our heads. Indeed, a steady decline in population to 19th century levels would be desirable.
And what is government policy??
the opposite of all of the above!
