Hi Ken, I was present at the launch of the NOAA updated report on the state of the Arctic at AGU in December*.
NOAA has singularly failed in its mission: To understand and predict changes in climate, weather, oceans, and coasts, To share that knowledge and information with others, and To conserve and manage coastal and marine ecosystems and resources. It has failed to predict changes in the Arctic as regards sea ice, temperature and climate, and it has failed to predict the effect of Arctic amplification on polar jet stream behaviour, weather extremes and hence the climate of the Northern Hemisphere. They seem to have lacked understanding of the force and progression of the vicious cycle of warming, retreat of snow and sea ice with a reduction of albedo leading to further warming. If they do have this understanding, they have failed to share that knowledge with others. They have neither taken action or recommended action to cool the Arctic as required to preserve the Arctic coastal and marine ecosystem, which are threatened by the virtual disappearance of the sea ice at the end of summer during this decade, as can be determined from a simple extrapolation of sea ice volume. They have ignored the advice of arguably the world's top sea ice expert, Professor Peter Wadhams, on the above matters. Cheers, John * At the press launch, a question was raised whether there was anybody in the room who knew about a proposal for geoengineering to cool the Arctic. I started to answer, but was told to shut up and was ushered out of the room! Thus NOAA are guilty of suppression of knowledge as well as the above failings! -- On Thu, Feb 28, 2013 at 4:00 AM, Ken Caldeira <kcalde...@carnegiescience.edu > wrote: > NASA's mission is to "pioneer the future in space > exploration<http://en.wikipedia.org/wiki/Space_exploration> > , scientific discovery <http://en.wikipedia.org/wiki/Science> and > aeronautics research." > > NOAA usually takes on operational tasks.
