Should humans address man-made rising temperatures and sea levels by tinkering further with mother nature? A lively debate about geoengineering has burst into the mainstream recently with reference to Ken Caldeira's work in the final chapter of the popular book SuperFreakonomics.
This panel takes a measured look at the good, bad and ugly of what could and should be done. What is technically feasible? How could new tactics be tested? Does the mere possibility of geoengineering diminish efforts to reduce carbon pollution? Our speakers share their distinct perspectives on this passionate environmental topic.
Ken Caldeira is an atmospheric scientist who works at the Carnegie Institution for Science's Department of Global Ecology. He researches ocean acidification, climate effects of trees, intentional climate modification, and interactions in the global carbon/climate system. He also works as a staff scientist for Intellectual Ventures, a Seattle-based invention and patent company headed up by Nathan Myhrvold.
Caldeira's work was featured in a November 2006 article in The New Yorker, entitled "The Darkening Sea." In 2007, he contributed two op-ed pieces on the subject of global warming to The New York Times. He was named a "Hero Scientist of 2008" by New Scientist magazine.
Gregory Dalton is chief operating officer at the Commonwealth Club of California and Director of The Club's Climate 1 Initiative. He previously was international editor at The Industry Standard magazine, an editor for the Associated Press in New York, and a correspondent in China and Canada for the South China Morning Post, a Hong Kong newspaper.
Proficient in both Mandarin and Cantonese, he is a former term member of the Council on Foreign Relations.
Albert Lin is Professor of Law at UC Davis School of Law.
His special interests include environmental law, natural resources, and evidence.
Dr. David Whelan is the Boeing Integrated Defense Systems Chief Scientist and Vice Presidentâ€”General Manager, Deputy to the President of IDS Advanced Systems. Whelan has responsibility to create, seek out and explore new technology and business growth vectors for the Boeing Company.
Boeing's technology and systems span a wide range of government missions ranging from space systems to airborne systems to ground systems to undersea system. Both manned and unmanned systems have been developed to solve Boeing's customer challenges. Leveraging his in-depth knowledge of science, technology, systems and future customer requirements Whelan enables Boeing to find new solutions to world's most challenging problems.
Deliberate or inadvertent alteration of atmospheric conditions by human activity, sufficient to modify the weather on a local or regional scale. Deliberate alterations include covering plants to keep them warm at night, seeding clouds to induce or augment precipitation, and firing silver-iodide particles into clouds to suppress or mitigate hail and to reduce fog at airports. Inadvertent alterations are the result of industrialization and urbanization, which have added billions of tons of carbon dioxide and other gases to the atmosphere (seeacid rain, global warming, greenhouse effect).
Wow... They guy only gets carried by the death of... a satellite! Now they will use all 3rd world crops to fly the planes that kill us.
So, is Mr. Knight doing this rogue? BS!
But hey... San Francisco croud, do you own a car??! (shoked)
We're so fucked.
The only thing this people want to cool down is the advancement of human consciousness.
They have been geoengineering least since the 2000 world-wide spraying of Aluminum particles. Do you remember the last time you saw a blue horizon.
They are destroying the acidity of the planet and the balance of all ecosystems on the premissive that the Earth is a lump of mass that you can control like a petri dish, using a "virtual thermometer" as all tool, while disregarding the fact that it used to be a complex self-balancing system in the first place, where we had our niche pretty much assured.
They are spilling fuels on the oceans, burning forests, changing the hold biosphere. Stearing storms... Many of us are dying already. But it's too late to stop polluting... let's TEST! Now... This they won't be able to hide: They are going to start to dump sulphur acid. Great downs I foresee.
This is a relaxed conversation between giggly potential genocides. Go Boeing... raise your shares.
One way how to, Help Mother Nature for a better climate.
Use mighty power of nature. In the northwestern Australia, we have huge tides,
huge evaporation and huge dry rivers and lakes.
Tides are up to 12m. Evaporation is up to 4m per year and can be increased.
Huge 12m tidal erosion can revive old dry paleo dormant once mighty rivers, creeks and lakes,
desalinate the country and change deserts to rain forests to provide more rain across Australia.
World population is growing rapidly and we need more energy, food, land and water.

this will change deserts and whole continent for better climate
environment, provide hydro energy, permanently.
Methane Releases from Arctic Shelf May Be Much Larger and Faster Than Anticipated
NSF, National Science Foundation - March 4, 2010.
Research results, published in the March 5 edition of the journal Science, show that the permafrost under the East Siberian Arctic Shelf, long thought to be an impermeable barrier sealing in methane, is perforated and is starting to leak large amounts of methane into the atmosphere. Release of even a fraction of the methane stored in the shelf could trigger abrupt climate warming.
As Martin Heimann writes in Science:
Wetlands and permafrost soils, including the sub-sea permafrost under the Arctic Ocean, contain at least twice the amount of carbon that is currently in the atmosphere as carbon dioxide. Release of a sizable fraction of this carbon as carbon dioxide and/or methane would lead to warmer atmospheric temperatures, causing yet more methane to be released. It would thus create a positive feedback loop that amplifies global warming.
Look, they created a program in the 70's-80's to remove the sulfur from the air, and now they are talking about putting it back. Nevermind the fact that 15 years is too short of a time to show a trend (in their own words). So they were trying to force AGW down our throats for 15 years and there's been no statistically significant warming over the last 15 years. It's much ado about nothing.
And heaven help us if we get any colder. Iowa has been getting colder for the last 3 years. #32 coldest winter, #2 coldest summer. This year #30 coldest winter. Not to mention snow in 49 states. It's not supposed to snow in Florida.
I wonder if we can't all stop for just a single moment to remember that engineers, financed by profit-driven organizations, are the principal architects of the mess we find ourselves in today. To suggest we hand that same basic group the keys to the family car and suggest they help us fix the problem smacks of denial and self-interest.
