Just got back from seeing An Inconvenient Truth

[Greeby]

If you're wondering why I'm only going now, the film only opened at the cinema here in Milton Keynes last Friday.

I left feeling like I need to do more. Yes, I've never owned a car, and always walked or used public transport. And yes, my town has bee lucky to have a paper, plastic and glass recycling scheme since 1993. But I still don't feel that's enough.

On another note, I'm usually a hard-bitten 23 year old cynic, but by the end of the movie, I nearly cried :cry:

1. The scary thing

is that the computer models used and the data used in the film are not the current thinking.

There are many runaway "reactions" that can happen if we reach tipping points (and we may have already
passed one or more). These include rapid releases of methane gas from the tundra as the permafrost layer melts,
huge releases of CO2 from the remaining forests when those forests are further stressed by climate change,
and the potential release of ungodly amounts of greenhouse gases if the oceans warm to a point where
ocean bottom deposits of CO2 hydrates suddenly disassociate.

The result of these titration point events is a planet that starts to look more like venus than earth. At least
for a large period of time. There would be a mass species die off.

We don't need to become carbon neutral, we need to be carbon negative.

And we may not have 50 years to figure it out. It might well be more like 10. Or less.

And we really have to address the population issue. I don't believe the earth can sustain 7 billion humans.
Certainly not with the resource consumptive lifestyle of "first world" countries (which larger fractions of
the total population are achieving all the time).
