What has the federal government done over the last eight years to stop global warming? Sadly, not much, despite numerous, dire warnings. Our new interactive timeline gives an at-a-glance overview of the scientific reports, lost policy opportunities, and environmental impacts over the last eight years. Click the forward and backward arrows to move through time, and click on a color-coded event box to learn more about it.

Besides giving a succinct summary of the last eight years, the timeline is fun to click around - lots of interesting information all in one place. And it makes it very clear what we need to do when the new administration comes in. There's no time to waste.
