TED Talk: James Hansen

2012/03/13

While I was working on the post “TED Talk.  The True Cost of Oil“, I came across another TED Talk that I thought I should share on this blog.  The presenter is world-renowned scientist and activist James Hansen and the title is “Why I must speak out about climate change.”

In 17 minutes, Dr. Hansen discusses a variety of subjects.  He begins by explaining how his career path brought him to the study of Earth’s climate.  In (understandable to the laymen) detail, he explains the physics of global warming as well as the evidence that it is currently affecting our climate.  He explains the consequences that we face if we do not act to reduce our carbon emissions but, he ends with what he believes is a simple solution: a gradually increasing carbon fee, the income of which is electronically returned to the tax payers.

This TED Talk is a profound look at the severity of the problem we face and the urgency with which we should be acting to reduce our carbon emissions.  I hope you’ll take the time to watch.

    I had the pleasure of listening to James Hansen live in Auckland some while ago (see my blog post “Judges, china, moral implications” http://sustainablefutures.info/2011/05/13/hansen-climate-judges-china-moral-implications/). A very respected person with an important message. Not sure about his stance on building more nuclear stations, but the sort of energy revolution necessary to run on renewables alone would probably be too much to ask from a person his age…

      Nuclear is a tough one. I remember hearing a talk by someone who had done the calculations of how much energy we consume and how quickly we need to transition to a low carbon energy system in order to avoid the bad end of climate change. And according to his math, there needed to be an increase of nuclear production in order to achieve our emission targets while maintaining energy production (I’ve just spent the last hour trying to find the video… but I’ve failed!).

      However, after having read your post about the James Hansen talk you saw and then going to your “Energy Autonomy” post, I’m seeing things a little different! Thank you for all that info 🙂

      With all due respect… did I see a little ageism creep in? Many of we oldsters are the strongest warriors.
