Fremtidens energiforsyning
16:14 | Fremtidens energiforsyning skal være baseret på vedvarende energi og uden fossile brændsler. Men det er ikke nok, bare at bygge en masse vindmøller, solvarmeanlæg og halmfyr.

5:26 | Capturing one photo per hour of daylight, the cameras placed on South Georgia (Antarctica) will document the story of the island’s melting glaciers.
12:03 | Er biogas svaret på de problemer, millioner af tons gylle fra den industrielle svineproduktion skaber?
7:31 | Climate change is real, so why the controversy and debate?
6:49 | In anticipating Pope Francis’ encyclical on climate change, catholics, protestants, scientists, and lay people discuss the ethics and spiritual meaning of climate action.
7:54 | John Cook explains the most effective way to debunk misinformation: fight sticky myths with even stickier facts and structure your debunking argument in three parts: fact, then myth, then fallacy.
8:00 | Learn about one of the best methods for making your science sticky – the SUCCES method developed by brothers Chip and Dan Heath. We use this method to respond to climate change myths.
5:55 | John Cook outlines how to stop science denial: by exposing people to weak forms of science denial.
5:59 | John Cook explains the vocal minority using research from The Six Americas report and from the article, “Your opinion on climate change might not be as common as you think,”
9:39 | John Cook explains the wordview backfire effect using examples from recent history and research. He also talks about ways in which we might combat this phenomenon when it comes to discussions of climate change.
8:27 | Climate change is real, so why the controversy and debate?
1:28:46 | Guardian Live – full event. A debate on the Guardian’s divestment campaign.
5:42 | Dana Nuccitelli examines climate sensitivity i.e. the amount of global warming expected from a doubling of atmospheric carbon dioxide.
2:56 | How could increased CO2 affect our crops? Although CO2 is important to plants, changes in other conditions such as water, nutrients, and pests are likely to mean that more CO2 will not mean better crops.
5:13 | Dana Nuccitelli explains how global warming affects polar bears through its effect on melting sea ice. Different types of sea ice melting mean different impacts.
4:55 | Dana Nuccitelli examines whether species can adapt quickly enough to survive rapid climate change. Five mass extinctions in the Earth’s past indicate there are limits to how much species’ abilities.
5:27 | Keah Schuenemann’s lecture explains how carbon dioxide affects water vapor in our atmosphere and also how the two greenhouse gases interact to form a positive feedback loop.
5:38 | Keah Schuenemann explains why global warming makes many types of extreme weather more likely. However, it is virtually impossible to say if a specific storm, heat wave, or other event was caused by global warming.
4:56 | Keah Schuenemann explains why heat waves are happening more often and how those heat waves are impacting our environment.
5:51 | Peter Jacobs talks about one of the more complicated questions in climate science: how will clouds change in a changing climate?
4:46 | Dana Nuccitelli looks at a number of ways that climate change will impact society, and how those impacts worsen with more global warming.
7:18 | Andy Skuce discusses a myth that exaggerates the potential risk from methane clathrate feedback.
7:00 | How will hurricanes be affected by climate change?
6:39 | Climate change is real, so why the controversy and debate?
3:10 | A common misunderstanding is thinking that CO2 cannot be a pollutant because CO2 isn’t toxic and it is found naturally in the atmosphere. Sara Green explains that CO2 IS a pollutant because of its effects on the environment.
8:07 | Climate change is real, so why the controversy and debate?
5:26 | Peter Jacobs explains climate proxies, which estimate temperatures in the Earth’s past. In particular, he looks at the divergence problem, where some tree-ring proxies diverge from recent instrumental measurements.
5:47 | Robert Way examines the Medieval Warm Period and how it compares to today’s temperatures.
4:54 | Dana Nuccitelli looks at what caused ice ages in the past and explains why we don’t expect them to occur in the foreseeable future.
5:56 | What were climate scientists thinking and publishing in the 1970s, before there was empirical evidence that the globe was warming? Daniel Bedford explains.
4:43 | Dana Nuccitelli explains the principles that climate models are built on: fundamental physical laws. No one can know the future for certain, but these models allow us to make educated decisions looking forward.
5:39 | Keah Schuenemann explains the role of the IPCC and their tendency to underestimate climate impacts.
6:23 | Keah Schuenemann explains the differences between weather models and climate models.
5:48 | Observing the effects of ancient CO2 levels and their correlation to ancient climate change can inform us what to expect today.
28:02 | Mycle Schneider, an independent international energy and nuclear policy consultant, provides an economic analysis of the cost of nuclear power including data using charts and graphs.
4:32 | Mark Richardson takes us to the Reading University Atmospheric Observatory to explain how the greenhouse effect works. He concludes by busting the myth that the greenhouse effect violates the 2nd law of thermodynamics.
