Letter: Australian heat caused by carbon emissions
While we shiver and cough under our current inversion layer, down-under tennis players at the Australian Open suffer heat exhaustion at a sweltering 112 degrees. Australia's Bureau of Meteorology reported that the average temperature during 2013 exceeded the long-term average by 3.7 degrees, the country's hottest year since recordkeeping began in 1910.
This occurred without El NiÃ±o, which adds to warming in the South Pacific. Climate scientist David Karoly at the University of Melbourne wrote, "It is NOT (emphasis his) possible to reach such a temperature due to natural climate variations alone." The warming effect of greenhouse gas emissions "vastly increased the odds" for setting a new high, he noted.
Meteorologists, paleontologists, physicists, chemists, biologists, ecologists, oceanographers, geologists, geographers and mathematician modelers, each investigating the same question using their different technologies, come to the same conclusion: Human-caused greenhouse gas emissions are leading to increased atmospheric temperature.
To disregard these results as normal variation or as a conspiracy or collective bias among scientists is to be either a handsomely paid consultant for fossil fuel industries, an ideologue blinded by self-deception, a politician whose campaign is financed by undisclosed sources, or just a plain fool.
