Joe Bastardi, who has a long record of dissembling truthiness and truthlessness when it comes to climate scienceissues, appeared on Fox News (yet again). Of of his comments has received much attention:

BASTARDI: CO2 cannot cause global warming. I’ll tell you why. It doesn’t mix well with the atmosphere, for one. For two, its specific gravity is 1 1/2 times that of the rest of the atmosphere. It heats and cools much quicker. Its radiative processes are much different. So it cannot — it literally cannot cause global warming.
Putting aside the fact that his comment is at odds with nearly two centuries of science and scientific work when it comes to the greenhouse gas properties of carbon dioxide (CO2), Bastardi's comment drove a 'what if' scenario ... after the fold ...:

  • If CO2 molecules are heavier than "the rest of the atmosphere" then
  • Gravity (another one of those pesky Scientific Theories) would mean that CO2 molecules would concentrate closer to the earth which means that
  • Atmospheric concentrations of CO2 at sea level would be much higher than at altitude which means that
  • Sea-level CO2 concentrations would likely be lethal to humans which means that
  • All of humanity must live at altitude to avoid the poisonous atmosphere at sea level.


Next time I take myoxygen tanks children to the beach, thanks to Joe Bastardi's excellent scientific observation, I will make sure that we pack enough oxygen tanks for the week.  (After all, wouldn't want to have to pay the exorbitant prices a beach vendor would charge.)

Note: There are many who believe Joe Bastardi is a serious contender for the Geocronium Award:

to the climate change denier who exhibits the biggest apparent departure from reality
Of course, listen to Joe and Faux News and ignore the world's scientific associations' perspectives on global warming.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
