As I continue to learn more about the use of social media, I thought I would prepare a post with links to some of webcasts about emissions and climate change that have caught my eye over these last few months. Here they are, courtesy of YouTube and as a belated contribution to this year's Blog Action Day (which I did not know was to be dedicated to Climate Change !)
NB: I have embedded copies and provided some further links to the original source postings on this page. Be careful not to click too may links at once, or you may hear stereo (but out sync versions) of several presentations at the same time !!
GapCast - Carbon Dioxide (Energy)
|Professor Hans Rosling gives a lecture with animated statistics about the carbon dioxide emissions of countries since 1975 - this also includes a brief comparison of China and the US's dependencies on coal to produce electricity. Other webcasts on the same site cover topics such as urbanisation and 200 years that changed the World to reveal how related standards of living have risen since the beginnings of the industrial revolution. It would be interesting to see Gapminder produce an animation showing how much carbon dioxide each country has generated in total over the last two hundred years to arrive at our respective standards of living.|
Greg Carven - How It All Ends
|Greg and his alter-ego give a polished (and entertaining) presentation about the risk management strategies to be adopted in response to the threat of global warming. He argues the debate should not be about whether humans are changing the climate, but rather what is the wisest course of action to take in anticipation of the potential consequences. Well worth a replay if you wish to capture some of the finer points of Greg's thesis.|
David MacKay – How Many Light Bulbs?
|Professor Mackay is the author of an acclaimed book that explains the energy content of the goods and services we use and how a nation such as Britain might go about reducing its dependency on the fossil fuels that support its life style - see an earlier posting on this blog. In this video, he discusses the average individual's consumption of energy and points out that major changes in the way the UK generates and consumes energy will be required if the predictions of climate change scientists are to be heeded.|
There are other webcasts of note that I will aim to add to a future update of this post. These include:
- Purdue University's projects to visualise the emissions of carbon dioxide across the US.
- The Government of Victoria's Black Balloons energy saving campaign from 2006. An effective visualisation of what the emissions of greenhouse gases, particularly carbon dioxide could look like.
- Maps and flybys on Google Earth links to which I have included in other postings on this site.
- ... and lastly but not least, a charming webcast called I'm Ready (for December's meeting in Copenhagen) from Oxfam's time for climate justice (tcktcktck.org) website that another Typepad blogger, posted on Blog Action day.
All these authors or their sponsors have created fine videos and it is a shame to see that a few climate change deniers have seen fit to post rude and dismissive comments about their work on the associated YouTube web pages. This shows there is still a way to go before opponents begin to accept there is some merit in seeking ways to reduce our dependency on hydrocarbons and address the issue of greenhouse gas emissions.
These films have also got me thinking that perhaps I should try to make a video of my own to talk about some of the issues that I am raising in this blog. Scary stuff but then again, maybe I should have a go !!
