³Let¹s play with the one [CO2 emissions reduction] that really matters,²
he [Jim Thomas of ETC] said. ³That¹s
already hard enough.²

OK, there's that moral hazard again, but what about the moral hazard if
our "playing" (depressingly apt) with CO2 emissions reduction continues to
prove too "hard", for technical, economic, and/or political reasons. Isn't
there also a moral hazard in this scenario if we refuse to even evaluate
all Plan B options because of unconfirmed fears that their costs and
impacts will always outweigh the benefits, even if Plan A fails?

Considering ³Soft Geoengineering²
By Aaron Lovell  // Thursday, November 29, 2012

Even as the climate debate has been paralyzed by politics, the concept
of geoengineering has been in the news lately, most notably in October
when Russ George dumped 120 tons of iron particles into the Pacific
Ocean in a scheme to try and score carbon credits. Earlier this month,
the Wilson Center¹s Science and Technology Innovation Program hosted
an event taking a look at ³soft geoengineering² ­ techniques that
might have low or minimal environmental side effects but still address
or reverse climate change.

The idea of humans engineering the Earth¹s environment remains
controversial but has increasingly drawn interest from policymakers.
Last year alone, the concept of geoengineering garnered reports from
the U.S. Government Accountability Office, the Bipartisan Policy
Center, and the Wilson Center, among others.

Looking to move forward from the spate of 2011 reports, Robert L.
Olson of the Institute for Alternative Futures, in conjunction with
the Wilson Center, explored the concept of soft geoengineering in an
article in the September/October issue of Environment, which focused
on technologies with a ³gentler touch² than others associated with
geoengineering.

Olson discussed the article at the event, including the seven criteria
that could be used to evaluate any geoengineering technology that
claimed to be environmentally benign. According to the criteria, soft
technologies should:

Be able to be applied locally;
Be scalable;
Have low or no negative impacts on the environment (besides climate
change);
Be rapidly reversible;
Provide multiple benefits;
Be analogous to natural processes; and
Be worthwhile on the time/effect scale and cost effective.
The article further looks at five specific technologies and how they
matched up against these criteria. At the Wilson Center, scientists
behind two of these technologies discussed their work.

Leslie Field of Ice911 talked about her research on using inexpensive
materials to slow loss of ice and snow and encourage the natural
process of ice and snow formation. And Russell Seitz discussed the
possibility of using ³microbubbles² in the ocean in an effort to
reflect ³megawatts² of solar energy back into the atmosphere and
space.

But despite the purported lower risk of these technologies, many still
have serious concerns. At the panel, Jim Thomas of the ETC Group
raised concerns with the idea of benign geoengineering at a
fundamental level, calling it instead ³soft-sell geoengineering.²
Thomas pointed out that the idea remains fraught with risk. ³We
shouldn¹t get too desensitized to that,² he said.

Further, Thomas raised concerns with what increased use of
geoengineering could do to international talks on emissions
reductions, particularly when some parties will argue against further
emissions cuts because of geoengineering activities.

³Let¹s play with the one that really matters,² he said. ³That¹s
already hard enough.²
