NASA Out of Control

NASA scientist out of control

James Hansen, Director of the NASA Goddard Institute for Space Studies in New York City, personifies American author Mary McCarthy's observation that "Bureaucracy, the rule of no one, has become the modern form of despotism." Hansen has used his NASA position to misdirect public policy on climate change for 24 years. His recent pronouncements that humanity is causing a dangerous increase in extreme weather have a similar disregard for scientific accuracy.

The public are turning away from claims of human impacts on climate. Politicians use the poor economy as an excuse to cut funds and bypass the issue. As a result, a counterattack is underway by those using global warming for a political agenda. At the forefront again is NASA bureaucrat Hansen, who put climate activism on the world stage before then-Senator Al Gore's Science, Technology and Space committee hearings in 1988.
A year ago, a Gallup World Poll (link) found that, for the planet, only 35% believed that Humans caused Climate Change with a similar percentage for the US (34%).

Dr Ball continues:
Hansen told the hearing that he was "99 percent sure . . the [human caused] greenhouse effect has been detected and it is changing our climate now." No scientist would make such a claim. It even contradicts what the United Nations Intergovernmental Panel on Climate Change (IPCC) said in 1995. They asserted,"…no study to date has positively attributed all or part of climate change observed to man-made causes." Hansen's 1988 predictions have turned out to be 150 percent wrong.
Undeterred, Hansen now writes that he underestimated how bad things would actually get and makes even more of the sort of mistakes that have been typical throughout his career. In his July 2012 article, The New Climate Dice: Public Perception of Climate Change, he and his co-authors cite the 2007 IPCC Report which said "...observed global warming is now attributed with high confidence to increasing greenhouse gases (IPCC 2007a)."
Dr Ball says that real world  observations show that temperature has declined as atmospheric CO2 increased. In fact, ice core data show that rise in temperature precedes rise in atmospheric CO2. There is a log of around 800 years. From Joanne Nova (Link):
It’s impossible to see a lag of centuries on a graph that covers half a million years so I have regraphed the data from the original sources, here and here, and scaled the graphs out so that the lag is visible to the naked eye. What follows is the complete set from 420,000 years to 5,000 years before the present.
Dr Ball asks us to consider the comment by German physicist and meteorologist and Klaus-Eckard Plus:
Ten years ago I simply parroted what the IPCC told us. One day I started checking the facts and data – first I started with a sense of doubt but then I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts and measurements. To this day I still feel shame that as a scientist I made presentations of their science without first checking it. The CO2-climate hysteria in Germany is propagated by people who are in it for lots of money, attention and power.
Dr Ball concludes:
It is clear that Hansen has used his position for political activism and abuse of public trust. As a US Federal bureaucrat it appears he has violated the Hatch Act defined as follows:
Enacted in 1939, the Hatch Act (5 U.S.C.A. 7324) curbs the political activities of employees in federal, state, and local governments. The law's goal is to enforce political neutrality among civil servants: the act prohibits them from holding public office, influencing elections, participating in or managing political campaigns, and exerting undue influence on government hiring.
The public has a right to know who is protecting James Hansen and why are they doing it.
