Lethal injections Science: Geo-engineering scheme damages the ozone layer	Joseph Romm	30 May 2008	Gristmill
Science has published a major new study, 'The Sensitivity of Polar Ozone Depletion to Proposed Geoengineering Schemes' ($ub. req'd). The study finds: The large burden of sulfate aerosols injected into the stratosphere by the eruption of Mount Pinatubo in 1991 cooled Earth and enhanced the destruction of polar ozone in the subsequent few years. The continuous injection of sulfur into the stratosphere has been suggested as a 'geoengineering' scheme to counteract global w ...

Time to Move to Mars Are fixing the climate and the ozone layer mutually exclusive?		24 Apr 2008	News
Posted at 3:59 PM on 24 Apr 2008 A geoengineering scheme to solve climate change could hurt the Antarctic ozone layer, while recovery of the ozone hole could increase Antarctic warming, new research suggests. A study published Thursday in Science decries suggestions to solve climate change by spewing sulfur into the atmosphere, saying that such a scheme would wipe out the Arctic ozone layer and delay the healing ...

Screwing with the planet, but on purpose this time Geo-engineering: cooking up solutions just like nature used to make	Ashley Braun	10 Mar 2008	Gristmill
Geoengineering may be an awful idea for reversing the warming effects of climate change, but it sure makes for a sweet subject of satire, à la this retro-style informational video. Like they say, 'If you can't fix the problem, techno-fix the problem!' After all, technology will save the world. Because we know everything there is to know about the planet and all. Not to mention what happens when we mess with it. So, instead of cleaning up and trimming the world's ...

Climos Def New company wants to seed ocean with iron to sequester carbon		05 Mar 2008	News
Posted at 12:24 PM on 05 Mar 2008 Weeks after ocean-seeding company Planktos bit the iron dust, a startup called Climos is plowing ahead with a similar business plan: seed the ocean with iron dust to stimulate the growth of CO2-gobbling plankton, then sell offsets for the sequestered carbon. Climos has announced $3.5 million in venture capital and is backed by reputable investors: Tesla Chair (née Pay-Pal cofounder) Elon Mu ...

Strike While the Iron Is ... Whoops, Too Late Plan to combat warming by seeding ocean with iron runs out of funds		14 Feb 2008	News
Posted at 3:26 PM on 14 Feb 2008 Planktos, the company that proposed fending off global warming by seeding the ocean with iron dust, has failed to get enough funding to go forward with planned tests. Under the Planktos business plan, iron fertilization would encourage phytoplankton blooms, which would suck up extra CO2, allowing the company to sell carbon offsets. But it was not to ...

Planktos update	David Roberts	07 Nov 2007	Gristmill
Remember Planktos, the company that was going to sail into the Atlantic ocean and dump a bunch of iron ore, hoping it would stimulate CO2 absorption and profit the company via carbon offsets? Well, Andy Revkin brings news that the company has set sail. Guess the cat's out of the bag! (Planktos has been criticized on Gristmill here, here, here, here, here, and by a group of Greenpeace scientists here. Planktos CEO Russ George defended the company here.)

Industry's plan for us The many ways big money seeks to avoid reducing fossil fuel use	David Roberts	29 Oct 2007	Gristmill
The following is a guest essay from Peter Montague, executive director of the Environmental Research Foundation. ----- It now seems clear that the coal and oil industries are not going to allow the United States to curb global warming by making major investments in renewable sources of energy. These fossil fuel corporations simply have too much at stake to allow it. Simple physics tells us that the way to minimize the human contribution to global warming is to ...

Geo-engineering remains a bad idea Climate change mitigation strategy could actually damage the planet	Joseph Romm	19 Oct 2007	Gristmill
Earl Killian sends me this WSJ op-ed: 'Thinking Big on Global Warming' (subs. req'd.). He sees some good news in it -- the WSJ 'published a non-denier [opinion] piece.' Yes, but geo-engineering is one of the delayers' sexiest strategies -- holding out the promise of a pure techno-fix that doesn't require all those annoying regulations needed to completely change our energy system. The conservative (duh!) authors of the WSJ piece embrace trying to 'develop capabiliti ...

Geo-engineering is not the answer To solving our global warming problem	Joseph Romm	15 Aug 2007	Gristmill
Geo-engineering is 'the intentional large scale manipulation of the global environment' (PDF) to counteract the effects of global warming, which itself was unintentional geo-engineering -- although today you'd have to say global warming is intentional, since everybody now knows what we're doing to the planet. But I digress. We're screwing up the planet with unrestricted greenhouse-gas emissions, and the question is, do we want to try to fix that problem by g ...

Rule three of offsets: No geo-engineering Smacking down a bad idea	Joseph Romm	27 Jul 2007	Gristmill
I know you've all been eagerly waiting for this (don't worry, I don't have many more rules). I got sidetracked by last week's offset hearing. Offset projects should deliver climate benefits with high confidence -- that's a key reason trees make lousy offsets, especially non-urban, non-tropical trees. An even more dubious source of offsets is geo-engineering, which is 'the intentional large scale manipulation of the global environment' (PDF) to counter ...

Planktos president responds to environmentalist critics In an op-ed, Russ George claims his company has been unfairly maligned	David Roberts	28 Jun 2007	Gristmill
A company called Planktos has taken some lumps on our site, so when their president, Russ George, sent this response along, I agreed to run it. (It ran originally in the Ottawa Citizen.) Your responses are welcome, but please, keep them civil. ----- As someone who has committed most of my waking life to caring for the planet, recent misleading reports on the foundations and future of my current company's work have led me to reflect on some large and important que ...

Irony Of Iron Ease U.S. EPA challenges California company's plankton-seeding plan		19 Jun 2007	Daily Grist
Irony Of Iron Ease U.S. EPA challenges California company's plankton-seeding plan A California company's plan to fight climate change by seeding the ocean with iron dust is drawing fire from the U.S. EPA, which reportedly woke from a nap with the vague feeling that it ought to be doing something regulatory. The company, Planktos, will use the iron to spur the growth of phytoplankton, which ...

Reflections On albedo	Umbra Fisk	23 May 2007	Ask Umbra
Hi Umbra, Can we make small changes to increase the albedo in the Northern Hemisphere? Choose white or light-colored autos (white is safer, anyway), white or light-colored roofs. Could we float white "islands" (recycled Styrofoam) in our lakes and oceans in locations that would not disrupt transportation? Sometimes white plastic bags get caught in the branches of trees and I've been so angry about that litter -- maybe I should appreciate ...

One and a half cheers for goofy offsetting projects Planktos may be a bad idea, but innovation is good	Adam Stein	04 May 2007	Gristmill
The green blogosphere generally reacted with chuckles or consternation to Planktos' announced plans to dump tons of iron into the ocean to, you know, see what happens. Gar Lipow took the article as another excuse to bash carbon offsets. To follow the logic, you first have to know why anyone would want to dump several tons of iron into the sea. Planktos hopes to demonstrate that seeding the oceans with certain nutrients is a credible way to stimulate plankton blooms. ...

Polluting to save the planet: RealClimate disapproves And why wouldn't they?	Gar Lipow	04 May 2007	Gristmill
RealClimate, a blog run by leading climate scientists, thinks Planktos's scheme to dump iron particles in the ocean to make plankton bloom and sequester carbon is 'thin soup.' I have some extended quotes from David Archer on the subject below the fold. But if you are interested, read the whole thing. In spite of public relations claims by Planktos representatives in comments, it appears that most of the scientific community does not think highly of the Planktos claim ...
