Scientists find CO2 not to blame for dry climate in southwest US, instead is aerosols and ozone esp. from SE Asia-Nature Mag. study May 2012

CO2 continues to prove it did not merit its own commodity exchange:

5/16/12, "Recent Northern Hemisphere tropical expansion primarily driven by black carbon and tropospheric ozone," Nature, Robert J. Allen, lead author

"Heterogeneous warming agents—including black carbon aerosols and tropospheric ozone—are noticeably better than greenhouse gases at driving expansion."...

Southeast Asia reference:

5/18/12, "CO2 Not to Blame for Southwest Droughts?" World Climate Report

"According to Allen et al.:

“Our analysis strongly suggests that recent Northern Hemisphere tropical expansion is driven mainly by black carbon and tropospheric ozone, with greenhouse gases playing a smaller part.”...

The authors argue that there is a good likelihood that black carbon emissions have been underestimated—especially those arising from Southeast Asia....

The bottom line is that the primary influences on a major component of the earth’s atmospheric circulation and thus general weather patterns turns out to be, on further examination, not atmospheric greenhouse gas concentration changes, but rather black carbon (soot) and tropospheric ozone. And one impact from the forced atmospheric circulation changes is a tendency for more aridity across the Southwestern U.S.

So, the EPA can try all they want to reduce U.S. greenhouse gas emissions, but no matter how successful they are, they will have little impact, if any, on the future of drought in the Southwestern U.S., as drought there is a complex interaction between natural variability and human climate alterations—of which, as shown by Allen et al., greenhouse gases play only a minor role.

So much for the “robust” signal that human greenhouse gases will lead to more drought in the Southwest.

It seems like a reassessment of this projection is in order—by the IPCC, the USGCRP, and the EPA."

Yale 360's headline and synopsis don't mention CO2 or that the Nature study's key point is that a dry southwest climate can no longer be blamed on CO2 or other greenhouse gases. Yale 360's headline and synopsis don't allow one to know why the study ended up in Nature. That a tropical zone expanded was not news. The news is that CO2 had erroneously been blamed for this.

5/18/12, "Human-made Pollutants May Be Expanding Tropical Zone, Study Says," Yale 360, e360 Digest

"U.S. scientists say emissions in the Northern Hemisphere of black carbon aerosols and ozone, both of which absorb solar radiation, are likely causing the hemisphere’s tropical regions to expand poleward."...

'Climate change' had nothing to do with 2011's largest fire in Arizona history. It was an untended campfire in a national forest. The fire came close to U.S. Army’s Fort Huachuca but not because of excess CO2 as University of Arizona climate profiteer Sagarin suggests.

8/24/11, "Feds charge 2 in devastating Wallow fire," AP, East Valley Tribune

"Federal charges have been filed against two cousins accused of accidentally causing the largest forest fire in Arizona's history by leaving a campfire unattended.

The U.S. attorney's office on Wednesday announced the charges against Caleb Joshua Malboeuf, 26, of Benson and David Wayne Malboeuf, 24, of Tucson.

The U.S. Forest Service said its investigators determined the men were camping in the Apache Sitgreaves National Forest when the fire began there May 29.

The agency said the two were out hiking when their campfire spread outside its fire ring in high winds....

The men each face five counts, including leaving a fire unattended and failing to maintain control of a fire that damaged a National Forest System....

Winds whipped the Wallow fire as it burned more than

538,000 acres in eastern Arizona and parts of western New Mexico, destroying 32 homes, four commercial structures and 36 outbuildings....

Monsoon rains eventually put out the flames."...

Arizona Republic op-ed writer and University of Arizona ecologist Sagarin says the 2011 Arizona fire came 'up to the doorstep' of the US military and convinced them global warming is a national security threat--not because of an untended campfire but via alleged ongoing CAGW. Sagarin says global warming requires beefing up forces in Arizona, that training in 'climate change' is needed, and in fact has been purchased from people such as himself at the University of Arizona. All courtesy of the US taxpayer via the US Dept. of Defense:

4/22/12, "Defense Dept. on front lines of climate-change issue," ArizonaCentral.com, Opinion, by Rafe Sagarin

"While the international community repeatedly stalls on taking meaningful action about climate change, there is one internationally focused organization that isn't waiting around -- the U.S. Department of Defense.

The generals and admirals there already see how climate change is affecting their operations and their strategic planning. ...

The Southwest region of the U.S. in particular is a critical zone for Defense Department readiness."...

Ed. note: Sagarin repeats the false claim that the 'international community' hasn't taken action on global warming. The 'community' is completely consumed with the topic even though it doesn't exist, has diverted billions of taxpayer dollars to save the climate and social justice, enacted countless laws and regulations, and made 'climate alarmism' the biggest profit center at investment banks. Sagarin is making money off of it himself, he should know.
