Geoengineering Scientists and Congress

Geoengineering is a wonderful example of taboo science. Most people would fall within 2 camps. Camp 1 considers geoengineering with disdain as it mucks with the natural environment. Camp 2 probably wouldn’t want their government involved in planetary climate control. With those entrenched camps where do scientists fit in?

Scientists were called as witnesses before The House Subcommittee on Energy & Environment last week in regards to geoengineering. The witnesses invited were…

• Klaus Lackner (Geophysics,
  Earth and Environmental Engineering): Covering CO₂ sequestration
• Robert Jackson (Biology): Covering Biological and Land Strategies to lower CO₂
• Philip Rasch(Atmospheric Science but a chemist by training): Calling for a Manhattan project type approach to researching geoengineering
• David Keith (Chemical and Petroleum Engineering): Mainly advocating that some sort of global policy towards geoengineering needs to be developed. The most sane and coherent witness; scientists don’t usually fair well before politicians.

So why care about taboo science? The simple matter is that it would cost 1-2 billion a year to return the planet to pre-industrial levels of temperature, assuming they use cheap sulphates to do the job. This means any number of nations, frankly any wealthy cohort of industrialists, can take climate control into their own hands.

Since geoengineering is a delicate subject to broach to the public, transparency is crucial and wasn’t loss on the chairman Brian Baird (D-WA). Congressman Baird mentions how some citizens believe their government is placing psychotropic drugs in jet fuels, the so called chemtrails and remarked “…legitimate scientific research [in geoengineering] must not get tied up in these kind of things.”

However, all the scientists were taken aback by Randy Neugebauer (R-TX), my favorite exchange was the following.

Randy Neugebauer (R-TX)

Randy Neugebauer, “What percent of the atmosphere is CO₂?”
Scientist, “390 parts per million”.
Randy Neugebauer, “Less than one tenth of one percent…This tiny minuscule amount…[can't] be more important factor in our climate than solar activity”.

I’m not even sure where to begin to broach such a deep misunderstanding of climate change. I would have mentioned to Mr. Neugebauer that he would be dead if that minuscule amount of CO₂ was removed from the atmosphere, as all plants would die followed by animals in short order. The concept of small amounts having huge impacts in large dynamic systems is an important lesson to teach, even more so to do it dexterously. These types of exchanges went on for some time. I’m left wondering why Randy Neugebauer is even on the Subcommittee on Energy & Environment in the first place.

The ranking Republican, Bob Inglis (R-SC), had this to say in his last remarks, “I believe in a basic role of government is to do basic research, its an important function that we do.” It is nice to know that basic science research is appreciated by both sides, even though there is always a rogue member in every committee.
