If CO2 is really such an all-powerful warming factor, and if the science is so settled, why does warmist Gavin Schmidt have so much trouble explaining why the southeastern US hasn't warmed since the 1930s?: "Whether this is due to some oddity in the weather patterns, air pollution effects, irrigation or something else is unclear."

Alabama's heat wave: A preview of global warming or just a hot spell? | al.com

HUNTSVILLE, Alabama Alabama's heat wave is just part of the normal climate roller coaster, not global warming, according to state climatologist and University of Alabama in Huntsville climate scientist Dr. John Christy...
"Since (today's) temperatures aren't higher than earlier temperatures, it doesn't look like 'global warming,'" Christy said, "but more like a problem we still wrestle with: unpredictable natural variability." Christy said no one knows what causes these natural shifts in climate.
"The heat wave today is primarily natural climate variability," agreed Dr. William Patzert, an global climate change researcher with the Jet Propulsion Laboratory at the California Institute of Technology in Pasadena.
"But it's also a preview of coming attractions of what we are contributing to the atmosphere in greenhouse gases, which is definitely gonna heat it up," Patzert said Friday.
"I am sounding the warning about what global warming will do out into the future," Patzert said. "If you think it's hot today, come back and take the temperature on July 6, 2050." A hot summer day in 2050 or even 2030 could be 115 degrees, Patzert said.
Patzert said the Earth is about 1.6 degrees Fahrenheit warmer than it was 129 years ago, when Alabama began keeping the weather records Christy has researched. "The unequivocal proof of that is that much of that warming has gone into the oceans," Patzert said. "We have seen an 8 inch rise in global sea level."

...Other climate scientists asked by The Huntsville Times to review Christy's findings last week also cautioned against linking Alabama's current climate and "global warming."
"It is true that one of the few places in the world where temperatures have not exceeded temperatures in the 1930s is the southeastern U.S. (including Alabama)," Dr. Gavin Schmidt, a climatologist at NASA's Goddard Institute for Space Studies in New York, said in an email. "Whether this is due to some oddity in the weather patterns, air pollution effects, irrigation or something else is unclear."
But Alabama weather over the last 100 years or so has "very little to do with global warming," Schmidt said. "It certainly isn't the case that predictions of Alabama temperatures can ignore what's happening globally," Schmidt said. "It is just that there is more noise ... when you get to the state or local level. "
Dr. Virginia Sickle-Burkett, chief scientist for global change research with the U.S. Geologic Survey, said in an email that the role of humans in climate change has been demonstrated scientifically.
"Multiple lines of scientific evidence [like what, specifically?] indicate that most of the increase in average global temperatures since the mid-20th century is due to human influences on the atmosphere," she said. Sickle-Burkett agreed with Schmidt that the Southeast's climate has been less affected so far, for some reason, but that global warming is real.
