A syllogism for climate change

As it gets harder for anyone to believe that the global climate is not changing, the argument seems to be shifting to whether or not the changes are caused by humans.  For this, I remember the concept of a syllogism from my sophomore class in philosophy.  Herein, some logic:             Carbon dioxide in the atmosphere warms the Earth.              Humans emit carbon dioxide to the atmosphere.               Humans are warming the Earth.

Regulation–a new dirty word

The White House has decreed that for every new regulation enacted, two existing regulations must be nullified.  Regulatory overseers are now assigned to every Federal agency that might consider adding a new regulation.

Beginning about 10,000 years ago and extending to the advent of the Industrial Revolution, carbon dioxide in the atmosphere was roughly constant, indicating that natural sources were well-balanced by removals from the atmosphere (Fluckiger et al. 2002). The current rise in carbon dioxide is due to human activities, especially combustion of fossil fuels (Hofmann et al. 2009). Carbon dioxide is a “greenhouse” gas, inasmuch as it […]
