3:04 | What happens if we burn through all the coal and oil, and shale gas?
2:36 | Geoscientist and climate expert Richard Alley connects the dots of temperature to show the difference between short-term trends and long term direction.
2:40 | Richard Alley address a common argument about climate change: that increasing amounts of carbon dioxide, CO2, are coming from natural sources, like volcanoes.
3:25 | When Earth was much, much hotter it was fine for dinosaurs. We might not like it quite so much.
2:21 | It’s true that Earth’s a massive jigsaw puzzle, with lots of pieces intricately fitting together. But, Richard Alley argues, we already know enough to see the Big Picture.
4:18 | Some people say transitioning to clean energy will simply cost too much – “leave it to future generations.”
7:24 | Richard Alley puts numbers on global renewable resources: solar, wind, geothermal, biomass and conservation.
53:42 | Richard Alley explains the essential science of climate change, and the promise of renewable energy.
