How much land mass would renewables need to power a nation like the UK? An entire country’s worth. In this pragmatic talk, David MacKay tours the basic mathematics that show worrying limitations on our sustainable energy options and explains why we should pursue them anyway. (Filmed at TEDxWarwick.) Lesson by David MacKay.
This talk was given at a local TEDx event, produced independently of the TED Conferences. Dan Miller shares his passion and empathy for saving our planet. While focusing on a simple solution to help fix climate change, he alerts us on our responsibilities as engaged citizens to be involved and take urgent actions towards the […]

These are the lecture videos from the free UBC course Climate Literacy: Navigating Climate Change Conversations, which tackles the scientific and socio-political dimensions of climate change. This course introduces the basics of the climate system, models and predictions, human and natural impacts, mitigative and adaptive responses, and the evolution of climate policy. This course formed […]
There was much to be frustrated about this year. But there was hope, too: a big deal between the US and China, domestic regulations on power plants, and a global protest to demand action.
*** (19. MARCH 2011) WINNER OF YOUTUBE’S BEST NONPROFIT VIDEO AWARD!!! *** Fossil fuels have powered human growth and ingenuity for centuries. Now that we’re reaching the end of cheap and abundant oil and coal supplies, we’re in for an exciting ride. While there’s a real risk that we’ll fall off a cliff, there’s still […]
July 21 — Global warming turns 120 next year… sort of. Next year will be the 120th anniversary of the first time we figured out that human activity could be causing climate change. Since then, the science has gotten firmer and the politics have gotten murkier, but the outlook for the future remains uncertain. This […]
5C is the temperature increase above pre-industrial levels we are heading for if we follow our path of limited or no climate policy. 2C is the temperature increase above pre-industrial levels that most countries around the world have agreed would prevent dangerous climate change. This journey will describe how the energy system must change if […]
