It seems that every few weeks we hear or see some scientific data that seriously challenges the politically correct notion that the activities of man, burning fossil fuels for energy, are irreversibly and catastrophically damaging the Earth’s atmosphere and causing global temperatures to rise to dangerous levels.
There are two competing ideas about the last two decades of global temperatures: One says temperatures have plateaued for the last 18 years, but the other that says the rising temperature trend has continued through that period.
According to a CNS News story Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center (ESSC) at the University of Alabama/Huntsville, argues that there has been no global warming for at least the last 18 years, and bases that position on actual raw temperature data he and fellow University of Alabama/Huntsville professor and NASA scientist Dr. Roy Spencer collected from 14 instruments aboard various weather satellites.
