All of The Above

August 8, 2011 by Gernot Wagner

When most talk climate policy, they talk mitigation: decrease our ever increasing flow of carbon into the atmospheric sewer. Another piece of the puzzle is adaptation. We are way past the point where mitigation alone will do. We know we’ll feel the consequences of global warming for years, decades, and centuries to come. That’s why we...[read more]

In Memoriam: Steve Schneider Takes On Skeptics

July 21, 2011 by Gernot Wagner

If you think things are bad, listen to a group of climate scientists talk about geoengineering—literally hacking the planet. I had the pleasure of attending the Asimolar geoengineering conference last March and, while there, had the distinct pleasure of spending some time with Steve Schneider. Even among a group of some of the world’s...[read more]

Can GeoEngineering Halt Climate Change?

June 17, 2011 by Marc Gunther

John LathamIn 1990, a British cloud physicist named John Latham wrote a letter, [PDF, download] to the journal Nature, in which he suggested that injecting tiny droplets of water into marine clouds to increase their reflectivity might be a way “to inhibit or neutralize global warming. And then? “Nothing happened for 10 years...[read more]

Dumping iron: probably not a cool idea

January 30, 2011 by Marc Gunther

Did you notice that President Obama didn’t say the words “climate change” or global warming” in his 7,000-word State of the Union speech? He described government support for clean energy as an investment that will strengthen our security, protect our planet, and create countless new jobs for our people Partly this is repackaging, and not...[read more]

Geoengineering research, getting real

December 1, 2010 by Marc Gunther

Geoengineering research is emerging from the laboratory. Government-funded scientists in the UK are moving forward with a pair of small-scale, carefully-controlled experiments–one to test the qualities of particles that could be used to block the sun’s rays, and another in which droplets of water will be pumped into the air using a one-...[read more]

Geoengineering: A congressman’s thumbs up

November 1, 2010 by Marc Gunther

Before we get to today’s topic–engineering the climate– let me call your attention to a couple of news items that got my attention last week. First, a Chinese company called the Shanghai Electric Group signed a $10-billion deal to sell 42 coal-fired thermal-generation units to an Indian conglomerate called the Reliance ADA Group, the...[read more]

Is geoengineering ready for prime time?

October 18, 2010 by Marc Gunther

2010 has been a bad year for climate, and an even worse year for climate policy. But for that very reason, it’s been a good year for geoengineering—the notion that humans can deliberately manipulate the climate and cool the earth. Official Washington is starting to take geoengineering seriously: The Government Accountability Office and a...[read more]

Solar Warming and Our Sulfur Sunshield

October 13, 2010 by Geoffrey Styles

Two unrelated stories concerning the science of climate change caught my attention yesterday. The first was the announcement of a new report on solar variability, published in Nature, which appeared to upend established thinking about the impact of solar cycles on the earth's climate. The other was a discussion on Shell's climate blog of...[read more]

Collaborating with industry on publications and climate solutions

October 6, 2010 by Simon Donner

The article Geoengineering: The Inescapable Truth of Getting to 350 from online hybrid magazine / academic publication The Solutions Journal appeared in my inbox today. We can argue back and forth about the societal and ecological implications of geoengineering. That's not the point of this post. What struck me as unique in this...[read more]

Bill Gates Announces Funding for Seawater-Spraying Cloud Machines

May 14, 2010 by Big Gav

Inhabitat has a post on yet another crackpot geoengineering scheme - people really do waste a lot of time trying to find ways to avoid harnessing renewable energy sources - Bill Gates Announces Funding for Seawater-Spraying Cloud Machines. Environmentalists have long argued about whether geoengineering (using technology to alter the...[read more]

Is Bill Gates Backing Risky Geoengineering Projects?

May 13, 2010 by Taylen Peterson

Bill Gates, the very macro-founder of Microsoft and godfather to PCs everywhere, has begun channeling some of his massive coffers into green tech ventures. He may not be the first IT mogul to dive into green tech funding, but Gates is certainly diving in headfirst. The question is, is he diving into the shallow end? So far he’s...[read more]

Boys with toys: Bill Gates funds geoengineering projects

May 12, 2010 by Tyler Hamilton

The Ottawa Citizen has a story this morning about multibillionaire Bill Gates and his funding of projects that are aimed at controlling the Earth’s climate in the face of rising CO2 concentrations in the atmosphere and the resulting warming of the biosphere. I won’t go into too much detail, except to say that University of Calgary...[read more]

Pod science: PRI's The World Science

April 10, 2010 by Simon Donner

For all those lamenting the decline of science journalism in print and on television, its worth checking out the growing number of science podcasts. One great example is Public Radio International's The World: Science hosted by Rhitu Chaterjee. The show has a more global focus than most other programs, including some recent interviews...[read more]

A Framework for Geoengineering

April 7, 2010 by Geoffrey Styles

This week's Economist includes coverage of a recent meeting of scientists at Asilomar, in California, to discuss the ground rules for pursuing "geoengineering", the deliberate, large-scale modification of the earth's environment. The purpose of the geoengineering now under consideration is to limit or reverse the effects of climate...[read more]

Jeff Goodell’s take on the Asilomar geoengineering conference

April 1, 2010 by Lou Grinzo

A Hard Look at the Perils and Potential of Geoengineering by Jeff Goodell: In the beginning, I had my doubts. The Asilomar International Conference on Climate Intervention Technologies, held last week at the Asilomar conference grounds near Monterey, Calif., was touted as an “unprecedented” gathering of 175 scientists, environmental...[read more]
