Government wildfire data shows that the scale of U.S. wildfires has decreased dramatically since 1930, when wildfires burned more than four times the amount of acreage burned in 2012. In 1930, wildfires consumed more than 50 million acres of land, but in 2012 wildfires only burnt up 9.2 million acres.
According to the National Oceanic and Atmospheric Administration (NOAA), carbon dioxide concentrations were much lower in the 1940s (only 310 parts per million by volume), meaning global temperatures were cooler while wildfires were much more prevalent than today.
“These data suggest that extremely large megafires were 4-times more common before 1940,” South said, adding that “we cannot reasonably say that anthropogenic global warming causes extremely large wildfires.”
“However, in today’s world of climate alarmism, where accuracy doesn’t matter, I am not at all surprised to see many journalists spreading the idea that carbon emissions cause large wildfires,” South said.
