One of the biggest problems with trying to explain global warming is trying to explain things to people who don't have the 10+ year history of paying attention to this stuff. They don't read from scientific journals or have any idea the ppm of CO2 and methane in the air compared to 25, 50, or 100 years ago. They don't know how those readings from 100, 1000, or 1,000,000 years ago are come by. They insist that global warming is just a natural cycle even though the natural warming takes place over several tens of thousands of years instead of over 50 years.
The movie An Inconvenient Truth should help them if they'll just go see it.
It's much of what we expect from the trailers. Much of it is the a collection of well presented photos, charts, studies, and cartoons that have been seen elsewhere. But since Al Gore is who he is he's been able to get certain data and government studies declassified. He's had access to some scientists that don't focus on addressing the world at large.
Great movie. Take your kids, your parents, take your neighbors.
