This documentary about Gore and his presentation are as relevant now as when this was shot. We continue to pump CO2 into our atmosphere even as a majority of Americans have come around on the facts of global warming. Gore takes the optimistic position in "An Inconvenient Truth," but today we see that it is not "political will" that holds us back but the will of a few powerful, monied interests. In America science must bow to money, even when the future of our wellbeing is on the line. I think the average billionaire would rather be rich than healthy, rather make money than have a gorgeous Earth to live on.

The second lesson, ten years later, is that elections matter. George W. Bush and Donald Trump, the great presidential mistakes of the 21st Century, have dropped a ball that Al Gore and Hillary Clinton would have caught handily. Imagine where we would be with consistent, pro-environmental leadership for the last 20 years. "An Inconvenient Truth" isn't just a lesson in climate change. It shows the importance of our election in American later this year.
