"Indiana James" Hansen on "Why I must speak out about climate change"

It’s okay, just as long as you’re sincere.

Okay, I watched the video. Seems he assumed from the get-go that human CO2 emmissions from fossil fuels were going to cause catastrophe even before the science was in. Ever since the beggining he has been only looking for evidence to support his initial bias and discarding all evidence to the contrary. He is still doing that today, even thou sea rise isn’t accelerating (in fact ts seems to be slowing if not starting to go negative), the ice sheets aren’t melting, the hot spot is missing, the increasing heat content of the ocean has stalled, air temp have flatlined (or are slightly decreasing over the past 14 years) and are currently below even his “type C” temperature vs CO2 scenario . In contrast to the actual data, what Hansen has done is continually make numerous “corrections” to the data to try and keep his disproved CAGW religion alive.

From WIKI an unreliable source comes a short bio of a reliable AGW advocate. Model it then adjust the history to match the model.
James E. Hansen (born March 29, 1941) heads the NASA Goddard Institute for Space Studies in New York City, a part of the Goddard Space Flight Center in Greenbelt, Maryland. He has held this position since 1981. He is also an adjunct professor in the Department of Earth and Environmental Sciences at Columbia University.
After graduate school, Hansen continued his work with radiative transfer models, attempting to understand the Venusian atmosphere. Later he applied and refined these models to understand the Earth’s atmosphere, in particular, the effects that aerosols and trace gases have on Earth’s climate. Hansen’s development and use of global climate models has contributed to the further understanding of the Earth’s climate.
Hansen is best known for his research in the field of climatology, his testimony on climate change to congressional committees in 1988 that helped raise broad awareness of global warming, and his advocacy of action to avoid dangerous climate change. In recent years, Hansen has become an activist for action to mitigate the effects of climate change, which on a few occasions has led to his arrest.
In 2009 his first book, Storms of My Grandchildren, was published.[1]
I will note he still heads the GISS under the Obama administration. Lisa Jackson still heads the EPA. Chu heads DOE.. We should expect nothing less from the green agenda.

TED is turning into a circus for pseudo intellectuals promote.

Hansen: I was really lucky to go to the University of Iowa wher I could study under Professor James van Allen who built instruments for the first U.S. satellites. Professor James van Allen told me about observations of Venus, that there was intense microwave radiation. Did it mean that Venus had an ionosphere or was venus extremely hot. The right answer, confirmed by the Soviet Vanera[?] spacecraft was that Venus was very hot. 900 degrees Farenheit. And it was kept hot by a thick carbon dioxide atmosphere. I was fortunate to join NASA and successfully propose an experiment to fly to Venus. Our instrument took this image of the veil of Venus which turned out to be a smog of sulphuric acid. But while our instrument was being built. I became involved in calculations of the greenhouse effect here on earth, because we realized that our atmospheric composition was changing. … The greenhouse effect had been well understood for more than a century. … Gases such as CO2 absorbed heat thus acting like a blanket warming Earth’s surface.
Eh…I don’t think so James. This is the paper that got your job at NASA.

Abstract
A dust insulation model for the atmosphere of Venus is proposed in which the high surface temperature results primarily from a shielding of energy escaping from the planetary interior. The insulation is provided by micron-sized dust particles which may he kept airborne by mild turbulence. For an outflow of planetary heat of the same order as that on Earth, the required infrared opacity of the dusty atmosphere is ~10^5 and the same atmospheric structure accounts for the observed microwave spectrum, The dust insulation model predicts a systematic variation of radar reflectivity with wavelength and the observations are in good agreement. The otherwise anomalously low value of the differential polarization measured at 10 6 cm is expected in this model due to atmospheric absorption. The results indicate that the microwave phase effect is primarily an atmospheric phenomenon and hence the conclusions which have been drawn from it on the assumption that it is a subsurface effect are in doubt, If the cloud particle properties observed in the visual region (high particle albedo and strong anisotropy of scattering)exist throughout the atmosphere then it is possible for the incident solar energy to cause a small surface temperature variation despite the huge optical thickness of the atmosphere.
Dust, the stuff that cools planets, not CO2 was your culprit.
And scientists at NASA (and elsewhere) were predicting a new ice age at the time
