Physics Today on geoengineering

August 4th, 2008, by kevin

In “Will desperate climates call for desperate geoegineering measures?“, Physics Today surveys the rationale for researching geoengineering, and discusses the prominent areas of research. Noteworthy is the opinion of Dr. Ralph Cicerone, President of the US National Academy of Sciences, who favors research before widespread implementation and highlights “the need for a qualified agency to oversee the design, implementation, and monitoring of experiments.”

New articles in Geoengineering Roundtable

July 29th, 2008, by kevin

The Bulletin of the Atomic Scientists has two new entries in the Geoengineering Roundtable. This brings a total of ten articles by preeminent scientists in the geoengineering debate.

Read:

Designing a geoengineering research agenda should be a group effort
Dan Whaley and Margaret Leinen of Climos.

We should plan for the worst-case climate scenario
Ken Caldeira of Stanford University.

Dan Whaley interviewed on the BBC World Service

July 25th, 2008, by kevin

Dan Whaley, CEO of Climos, is interviewed by Peter Day of the BBC. This is a follow-up to an interview published in May 2008, and highlights several emerging clean technology solutions to climate change including OIF.

Ocean alkalinity modification proposal funded by Shell Oil

July 23rd, 2008, by kevin

Shell Oil has funded a proposal by Cquestrate to investigate atmospheric carbon removal by adding lime to sea water. This process is heavily energy intensive, but could still be cost-effective near oil fields that have un-utilized natural gas resources. Instead of flaring the gas, it could be harnessed to create lime from limestone. Notably, the company developing this proccess plans to use an “Open Source” development process so that anyone can use the technology.

Read a Wired article on the process.

Amazon River powers carbon sequestration

July 23rd, 2008, by kevin

A new paper in the Proceedings of the National Academies shows that nutrient-rich discharge greatly enhances the biological pump mechanism of carbon sequestration. The sequestration happens as the discharge plume enters deep water off the continental shelf, where excess iron, phosphorous, and silica stimulate diatoms and nitrogen-fixing diazotrophs. The measured carbon sequestration rates are very high in the area of the discharge plume.

Sahara dust essential for iron fertilization of Atlantic

July 23rd, 2008, by kevin

A new paper in Nature Geoscience highlights the importance of iron fertilization from dust storms blowing off the Sahara coast.  The dust “sustains life” in the tropical North Atlantic ocean by enhancing the growth of nitrogen-fixing phytoplankton that require iron.

Christian Science Monitor covers geoengineering

July 17th, 2008, by kevin

The Christian Science Monitor published this article, “Can we engineer a cooler Earth?“, which discusses the need for geoengineering as a stop-gap approach until the world can implement meaningful CO2 emissions cuts. Also mentioned is the need to begin researching how geoengineering could be conducted responsibly.

Earth2Tech on Planktos

July 7th, 2008, by dan

Katie Fehrenbacher at Earth2Tech covers the relaunch of Planktos under “Planktos-Science.com”.

She notes:  “If Planktos Science wants to be a serious company, they should get some serious PR help.”

Time Magazine covers OIF and Climos

July 3rd, 2008, by kevin

The July 3rd edition of Time Magazine has a story on OIF and other technologies to actively remove CO2 from the atmosphere. The story goes into significant detail on the reasons why CO2 sequestration is important, and on how OIF would accomplish this. Climos is covered, including a quote by Dr. Margaret Leinen.

Popular Science article on OIF

July 3rd, 2008, by kevin

Popular Science provides a nice post-mortem on Planktos, which ceased operations last February. The story of Planktos is a good example of the need for effective regulation of OIF activities under the London Convention.

The last page of the article has some nice coverage of Climos and the way forward with OIF. There are quotes by Dr. Ken Buesseler of the Woods Hole Oceanographic Institute, and by Dan Whaley and Margaret Leinen of Climos.
