“The Earth has Changed Before, What’s the Big Deal?” – Hansen on Deep Time

February 25, 2016

The new Hansen interview vid caused youtube to remind me of this jewel from my “Climate Denial Crock of the Week” series. (people say,” why don’t you do more of those” – dude, fund me. I’m working as hard as I can)

This is the video I refer people to when they give me the “earth has been warmer before, don’t scientists know that?” line. (trust me, scientists have thought of this)

I took a lecture that James Hansen had online, and enhanced with explanatory graphics – and a teensy bit of sarc. And it’s not your ears, the sound is muffled first 30 seconds.

Yeah. Scientists know it’s changed before.

65 million years in 8 minutes.

  1. There isn’t any sound on this.


  2. (people say,” why don’t you do more of those” – dude, fund me. I’m working as hard as I can)”

    I heard from no less of an authority than Ned Flanders that you were “well funded”.

    Something doesn’t add up here…

    Humans barely survived the consequences of the Toba eruption, there is a significant genetic choke point. What we are doing is so much more significant, our survival is not assured.
