James E. Hansen: “Earth’s energy imbalance” GISS Lunch Seminar 20110413

This is a really interesting presentation by Dr. James Hansen (NASA GISS/Columbia) of the main points from a paper, now published as:

Hansen, J., Sato, M., Kharecha, P., and von Schuckmann, K.: Earth’s energy imbalance and implications, Atmos. Chem. Phys. Discuss., 11, 27031-27105, doi:10.5194/acpd-11-27031-2011, 2011.

The paper can be downloaded for free at the journal website  here. The reviewers’ comments are also available.

The slides Hansen show in the presentation are hard to see in the video, but the figures are all in the paper referenced above.

Hansen’s presentation is not primarily aimed towards the general public, but he explains many of basic concepts and assumptions that are made in the paper, so it is not too hard to follow the presentation, especially if you also read the paper.
