Dear Al Gore:

We still haven't shown people that global warming matters to them in a real, present way. And they're not going to take action until it gets bumped a little higher on their subconscious priority list.

Let's make a cartoon short, showing the changing of the seasons in 100 or 200 years. Maybe there are some trees that stay fixed throughout the cartoon, and we start with fall when they drop their leaves quickly. Then there's a wet, sloppy winter with occasional deep freeze spells. Spring rolls around and there's some chirping of birds and little green sprouts sprouting. And then summer arrives, with the distorted optics of heat from the oven, and burning, screaming children running by.

It's a little grotesque, but you can do that in cartoons - Southpark has demonstrated that.
