When science is broken.
CLAIMS THAT THE CACHE OF E-MAILS HACKED from the Climate Research Unit of the University of East Anglia in the U.K. that showed researchers hiding and manipulating data, revealed nothing that would disturb the underlying consensus among climate scientists that warming is real and a major threat to the planet, may be true but misses a vital point. As the eminent physicist Freeman Dyson pointed out in an earlier context, science is advanced by dissent, not consensus. Schemes aimed at shutting up challengers to orthodoxy evokes the attempt to silence Galileo. What troubles Dyson, a scientist revered by other scientists, is that climate change consensus is riddled with "experts"--people who are crippled by the conventional wisdom they create because "they know it all."
