Global warming alarm was back in the news recently when the Natural Resources Defense Council claimed that hotter temperatures will soon lead to sharp rises in air pollution.  But according to Joel Schwartz writing for Tech Central Station, these claims ignore some obvious facts.  For starters, the NRDC used emissions levels from the mid-1990’s to predict future smog, even though those levels have dropped by 25 to 50 percent over the last 10 years alone and will continue to plummet.  But when you also consider the national average of smog alerts has also declined tremendously over recent decades during a period when the climate has supposedly warmed, this looks like just another example of overheated climate hype.
