[C]arbon dioxide is building in the atmosphere and rising to levels that have probably not been seen in along time (hundreds of thousands of years).

This rise is a continued reminder of the steady drumbeat of human progress. The carbon dioxide that is building in the atmosphere, at least in part, gets there through human emissions of carbon dioxide that are the by-product of burning fossil fuels (coal, oil, natural gas) to produce the vast majority the energy that has powered mankind’s industrial and technical ascent since the Industrial Revolution. . . .

The only concern that arises from growing atmospheric CO2 levels stems from the potential climate changes that may result. . . . We continue to detail the evidence that the earth’s “climate sensitivity” to carbon dioxide is less than expected.
