In the long history of evolution it has not been necessary for man to understand multi-loop nonlinear feedback systems until very recent historical times. Evolutionary processes have not given us the mental skill needed to properly interpret the dynamic behavior of the systems of which we have now become a part. J. W. Forrester, 1971

One Pinnacle of Human Achievement to Another
This week NASA is announcing where the soon-to-be-retired space shuttles will be displayed as museum relics. On April 19 the space shuttle Endeavor will be launched, on the penultimate mission of the program. The end of the space shuttle program will mean that the U.S. will have to rely on Russian rockets to deliver American astronauts to space, pending the development of private commercial spaceflight.

Ignorance is Bliss for Republicans

In addition to flattening funding for scientific investigation, the House Republicans’ proposed spending bill would devastate the federal government’s ability to study, understand, and communicate vital information about our changing energy sector. It would cut the Department of Energy’s independent Energy Information Agency by nearly one-sixth. EIA is the preeminent collector and disseminator of vital statistics and projections of energy production, consumption, and pollution.
The budget also would wipe out the “Greenhouse Gas Registry” that collects data on companies’ carbon-dioxide pollution. These two cuts would save a paltry $25 million. For comparison, this is just one-twentieth of the $500 million spent on military bands in 2010. The large congressional climate science denier caucus clearly believes that ignoring the problem will make it go away.
Well over half (55 percent) of the incoming Republican caucus are climate zombies. Thirty-five of the 46 (76 percent) Republicans in the U.S. Senate next year publicly question the science of global warming. Of the 240 Republicans elected to the House of Representatives, 125 (52 percent) publicly question the science.
Of the freshmen Republicans, 36 of 85 in the House and 11 of 13 in the Senate have publicly questioned the science. There are no freshmen Republicans, in the House or Senate, who publicly accept the scientific consensus that greenhouse pollution is an immediate threat.
Nearly all the rest of the Republicans in the 112th Caucus either signed the “No Climate Tax” pledge from the climate-denier Koch Industries front group Americans For Prosperity, the “No Cap-And-Tax” Tea Party pledge, or co-sponsored a resolution to overturn the EPA’s scientific finding that greenhouse pollution threatens the American public’s health and welfare.

Mysterious Ribbon Around Solar System

Whale's Eye Star and Cluster, Hubble Space Telescope
"We thought we knew everything about everything, and it turned out that there were unknown unknowns." Richard Fisher, Director of NASA's Heliophysics Division, upon discovery of a mysterious ribbon around our solar system —- a stripe made of hydrogen —- that defies all current expectations about what the edge of the solar system might look like.

Beating Around the Bush
New revelations about the Bush Administration’s arrogant disregard for responsible governance seem to come cascading down around us every day. The latest comes in the form of a Justice Department investigative report that concludes that hiring decisions at the Justice Department were illegally politicized. In other words, the sign over the door read, Bushies Only. We suspected as much when former Attorney General Alberto Gonzales, testifying before Congress on the firing of prosecutors claimed not to “recall remembering” being involved in or even being aware of the firing of prosecutors who were not Bush loyalists. Now, the report by the DOJ's own Office of the Inspector General and Office of Professional Responsibility states that
Monica M. Goodling, the White House Liaison at DOJ, and her deputies had broken civil service laws, run afoul of department policy and engaged in "misconduct" in the hiring and firing of prosecutors, judges, and other DOJ applicants/employees. Goodling is another Bush appointee chosen not because she was the best qualified for the job – she graduated from Messiah College and Pat Robertson’s Regent law school – but because she was a Christian conservative Bush zealot.
The Bush Administration has been infamous for its distortions and manipulations of the truth on many fronts. In another case, the panel that advises the Centers for Disease Control and Prevention on lead poisoning was planning to strengthen lead poisoning regulations in response to science showing that smaller amounts than previously understood could cause brain damage in children. Before the panel could act, then Secretary of Health and Human Services (HHS) Tommy Thompson, a Bush appointee, rejected the recommendation and replaced two members of the panel with individuals tied to the lead industry.
It was also under Thompson that HHS downplayed the true cost of the prescription drug benefit law by $150 billion. The actuary that pointed out the true cost was threatened with termination if he revealed to Congress his estimate.
Last month, the NASA Inspector General found that White House political appointees in the NASA press office "reduced, marginalized, or mischaracterized" studies of global warming, toning down politically unwelcome conclusions. A news conference on global warming was postponed, according to a senior scientist, because the Bush Administration did not want any negative environmental news before the 2004 election.
Under the Bush Administration, scientists who work for and/or advise the federal government have seen their work manipulated, suppressed, or distorted, while government agencies under the direction of Bush appointees have systematically limited public and policy maker access to critical scientific information. The Union of Concerned Scientists has constructed a clever web site in the form of a periodic table illustrating the wide spread manipulation of science by Bush and his minions.
But hey, "Great job, Brownie."
