No video recording was made of this lecture, but I made an audio
recording, and Prof. Happer generously sent me his Powerpoint slides,
which I combined into a usable video.-DAB
“Why
has there been no global warming for the past decade?”
The temperature of the Earth’s surface has not changed by more than
0.1C since the year 2000, and it may even have cooled slightly. Most
computer models predicted that the increase of CO2, from about 370 to
400ppm during that period, should have caused a warming of around 0.3C.
There are many possible reasons for the failure of the models, but one
may be insufficient careful attention to important and often neglected
details of how CO2 molecules really absorb and emit radiation in the
Earth’s atmosphere. Some of the physics in question is related to early
work by Princeton’s Robert Dicke on collisional line narrowing.
I made the audio recording of this lecture with
my mobile phone, while sitting in the audience. I took the middle seat in
the front row, to try to get the best sound quality I could manage, but
it's still mediocre. Sorry! The sound level is a bit low, too, but if you
turn up the volume it's understandable.
Five weeks later, on October 15, 2014, Prof. Happer delievered another lecture, at the George Marshall Instiute. You may view it here: http://www.youtube.com/watch?v=gMdYmAo08O4
Three months after that, in January, 2015, the Locke Foundation did a follow-up interview with him:

There have also been some exceptionally educational discussions on WUWT
about the physics of the so-called (misnamed!) “greenhouse effect.” Here are three of them:

Especially illuminating were several comments by Physics Prof. Robert Brown ("rgbatduke"):

Excerpt: “On the other side of things (escaping photons) you have the same problem, only
even more complex as pressure broadening means that heat leaks out along the edges of the
lines as they sharpen at lower pressures at higher heights, narrowing the absorption bands
above the emission bands below.”
