Howard Hayden, professor emeritus of physics at the University of Connecticut. submitted this comment on the draft of the U.S. State Department's Climate Action Report. He notes,
nary a word in the report even pretends to
* establish a link between CO2 and putative global warming
* show that the increase in CO2 concentration is due to human activity instead of natural causes (such as natural warming of the oceans)
* show that either an increase in CO2 concentration or an increase in temperature is, on balance, bad (or worse than laws restricting CO2 emissions) or
* do any science whatsoever.
