That hockey stick that deniers laugh at.

Let me see where else could we find it?
Migratory birds over-wintering - used to happen, now even non-twitcher can see it happening.
Spring arriving earlier. Autumn later.
Storm getting more frequent (forget thresholds for words, storms are stronger and more frequent at every arbitrary threshold).
Power generation.
number of cars/trucks built.
number of plane journeys.
population.
need for the Thames barrage.
etc etc.

Somewhwere in there is cause & effect.

You know when I wus a practicing enjuneer, I never, not, nohow solved a problem by denying its existence. Now I program PCs & Websites and - well you can imagine - denial ain't gonna cut it. Unless you are Apple (first class deniers) - give them a denial year to come clean about their software bugs. Be kind to them, they believe their own hype!

It doesn't fucking matter who caused the problem, JUST GET ON AND FIX IT, Stupid.
