Technology to Cool the Planet: An Interview with David Keith
Boston Review: First, can you explain to readers why sulfates are good candidates for geoengineering, as opposed to other molecules?
David Keith: Sulfates are the devil we know. Small water droplets would be roughly as effective as sulfuric acid in reflecting sunlight—clouds, composed of water droplets, are white and reflective—but they would evaporate almost instantly in the dry air of the stratosphere. The sulfuric acid keeps the water from evaporating.
Sulfur emissions from fossil fuel combustion are already cooling the planet and killing roughly a million people a year from air pollution worldwide. The amount of sulfur that would need to be put in the stratosphere for solar geoengineering would be a few percent of current fossil fuel emissions. Any such injection would carry real environmental risks such as ozone destruction and acid rain, but sulfates have the advantage of being a common atmospheric chemical, one that is injected into the stratosphere by volcanic eruptions. So although sulfates are risky, we have some empirical evidence about what the risks are.

David Keith: Sulfates are the devil we know. Small water droplets would be roughly as effective as sulfuric acid in reflecting sunlight…
Just a wonderful idea for the anti-human greens, reflect the warmth as we move into a cooling phase, and leave the planet cold as a stone and so crops don’t grow, and people die en masse. Da quotes:
“Isn’t the only hope for this planet the total collapse of industrial civilisation? Is it not our responsibility to ensure that this collapse happens?’” -Maurice Strong, ex UNEP Director
“I sometimes wish that we could have a lot of horrid things happening…” -Nobel laureate & climate activist Thomas Schelling
“The Earth has cancer and the cancer is Man.” -Club of Rome, Mankind at the Turning Point
“A cancer is an uncontrolled multiplication of cells; the population explosion is an uncontrolled multiplication of people. We must shift our efforts from the treatment of the symptoms to the cutting out of the cancer.” -Paul Ehrlich, Stanford U
“The big threat to the planet is people: there are too many, doing too well economically.” -Sir James Lovelock, BBC Interview
“A reasonable estimate for an industrialized world society at the present North American material standard of living would be 1 billion.” -United Nations, Global Biodiversity Assessment
“A total population of 250-300 million people, a 95% decline from present levels, would be ideal.” -Ted Turner, CNN founder & major UN donor
“My goal would be to reduce human population to about 100 million worldwide… [and] eradicating small pox was wrong.” -John Davis, editor of Earth First! ” -David Foreman, Earth First!
“The life of all mankind is in danger because of global warming .” -Osama Bin Laden

“You can go outside and spit and have the same effect as doubling C02?” – Reid Bryson, the ‘Father of Climatology’
“I’ve just completed Mike’s Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) and from 1961 for Keith’s to hide the decline.” -Phil Jones
If all of these people were so righteous, they would lead by example and voluntarily extinguish their own lives for the “cause”. But they don’t and they won’t because they’re giant hypocrites.
Indeed. Ted Turner has his fair share of kids I understand. Maurice Strong talks of wanting the collapse of industry after having made millions from big oil and industry. He too has his offspring as does David Suzuki with 5 kids. These people really are a bunch of hypocrites.
Didn’t one Kevin E Trenberth say: “any consideration of geoengineering [is] quite hopeless as we will never be able to tell if it is successful or not!”
Since the climate zealots don’t ever seem to be able to agree between themselves at the international level, it’s hardly likely that geo-engineering such as that proposed by the pictured idiot will ever happen.
There would be one hell of a class action suit if a glaciation ensued [very likely].
World War 2 also made it possible for many doctors to experiment with human beings.

“Sulfur emissions from fossil fuel combustion are already cooling the planet and killing roughly a million people a year from air pollution worldwide.”
Scientists do not make up ‘facts’, David Keith is obviously an activist.
“Will exposure to sulfates result in harmful health effects?
The following symptoms can appear a short time after someone drinks water that has over 500 ppm of sulfates:
diarrhea, intestinal pain (especially in babies)
dehydration as a result of diarrhea
slight decrease in normal stomach acidity
Breathing sulfates can cause lung irritation. No long-term human health effects are expected from exposure to sulfates. In animal studies, sulfates did not appear to cause cancer or birth defects.”

These folks seriously need counseling.
(As if we didn’t already know.)
BTW, I just checked temps in Washington, DC. Currently 16ºF. These are the folks that are protecting us from global warming.
Looks like they are doing a GREAT job….
This idiot was at the University of Calgary for a while…please don’t send him back to Canada. Here is a letter I wrote to the local newspaper about Keith’s idiotic ideas a few years ago.
RE: Sun screen idea floated January 28, 2010
Readers should be alarmed that their tax dollars are being wasted on the likes of U of C Professor Keith. He is proposing that he get grant money for the concept of seeding the atmosphere with particles to block the sun and make our weather colder than it already is.
Yet the world’s climatologists don’t know how climate and weather change. We now know that the role of carbon dioxide has been overblown by the politically motivated UN IPCC, by the sensation-seeking media and by grant-hungry researchers riding the “climate gravy train.” So bad is the “science” behind the UN’s 2007 climate report from IPCC, that University of Victoria’s oft-quoted Weaver (a global warming alarmist) recently said that the IPCC has crossed the line between political advocacy and science. Weaver has also linked extreme weather with carbon dioxide and yet the IPCC has been forced to admit that their 2007 report’s claim of link between carbon dioxide and media-hyped “extreme” weather was unfounded.
Now Professor Keith is proposing to study the addition of “stuff” to our atmosphere to stop climate change when we don’t even know how the climate changes! The arrogance is as amazing as it is frightening.
We know that volcanoes have drastic affects on climate as witnessed by terrible weather following Pinatubo, Krakatoa and Tambora. Now imagine putting a bunch of particles into the atmosphere, followed by an unexpected and major volcanic eruption. If you thought the past two winters have been cold, and if you blinked and completely missed the few days of summer in 2009, you will not like colder weather that Professor Keith is proposing to produce … summer-loving folks won’t like it one bit. (Here in Lethbridge, 2009 was the coldest year of the century and the coldest since 1996!)
Ignatieff, Suzuki, IPCC, Gore and their dangerous ilk (including some academics here in Lethbridge) want the world to waste trillions because they wrongly believe they have power over the world’s climate. In the meantime hundreds of millions of the world’s poor don’t have adequate health care and clean water. An immoral crime.

Excellent letter and points.
What a fffin moron.
People like this need to be locked up or, since they are so determined to live on a colder planet, sent to Pluto.
Cyanide is also a devil we know.
Environmentalists don’t like people. That’s not really new.
I thought the greens lead the fight against acid rain to “save the planet” in one of the first anti-pollution campaigns.
Now their “heroes” propose bringing it back to “save the planet” ??
Save the Planet, Kill Yourself
Wasn’t he the EPA officer in Ghostbusters?
Reblogged this on wwlee4411 and commented:
Man made efforts to control the weather don’t work.
You think David Keith is nuts?
Check out this kook!

None other than Obama’s Science Czar.
One wants to poison the air, the other the water supply – Good grief, we’re surrounded!
This moron thinks =SO4 will stay in the atmosphere? It’s going to fall the first time it rains….acid rain. Look at him, you can see the permanent bong marks on his lips. Who hires LSD burnouts as professors, anyway? Can’t Calgary find somebody sane?
