Back in the late 1990s, Ken Caldeira set out to disprove the "ludicrous" idea that we could reverse global warming by filling the sky with chemicals that would partially block the sun. A few years earlier, Mount Pinatubo had erupted in the ...
A Feb. 10 release from The National Academies explored the topic of climate
intervention, also known as geoengineering
involves removing existing carbon dioxide from the atmosphere and reducing the amount of sunlight entering the ...
Senior US climate
scientist Professor Alan Robock, from Rutgers University in New Jersey, has expressed concern the geoengineering
, manipulating the climate
, could be used as a weapon in the future.
Geoengineering involves manipulating ...
Efforts to reduce emissions of climate
-disrupting greenhouse gases are moving at a pace that is, well, glacial. Human activity continues to spew tens of billions of tons of carbon dioxide into the air every year. And even though a bone-chilling ...
The CIA is worried that a foreign power may develop the ability to manipulate the global climate
in way that cannot be detected, a leading climatologist has claimed.
Consultants working for the Central Intelligence Agency have asked ...
US scientists and legal experts are calling for a strong, international authority to regulate any man-made interventions meant to combat global warming, amid fears that the technology could be harmful to the environment.
The field known ...
Scientists are so concerned about global warming that they're now calling for tests to find ways to cool the planet -- the first step toward exploration of a highly controversial field that sounds like science
It could be the plot of a science
-fiction thriller: fertilize the ocean with iron to suck up coral-killing carbon dioxide or seed the skies with tiny droplets to block the sun’s rays.
In a report released Tuesday, a National Academy of ...
Developing the technology to suck planet-warming carbon dioxide back out of the atmosphere is an expensive but promising approach that may be necessary to help prevent the worst effects of climate
change, according to the first of two reports ...
Fifty years ago, the idea of reducing the amount of sunlight reaching the earth to address climate
change officially entered the scientific and political vernacular. That concept has since been lumped under the banner of geoengineering
with other ...
Sure, we can fight the effects of climate
change by cleaning the emissions from cars and putting scrubbers on the smokestacks of power plants. But doesn't a massive problem require a big solution like, say, spraying sulfur dioxide into the ...
change has advanced so rapidly that the time has come to look at options for a planetary-scale intervention, the National Academy of Science
said on Tuesday. But it was categorical that such ‘geoengineering’ should not currently be ...
Academy Sees Merit in CO2 Removal, Risk in Reflecting SunlightBy Andrew C. Revkin February 10, 2015 11:00 am February 10, 2015 11:00 amPhotoGlobal warming might be slowed by ...
As we watch the new GOP-controlled Congress clash over the Keystone XL pipeline, it’s rather depressing to realize that this is just the beginning of the pitched, drag-out battles to come over climate
change in the next two years.
Some people might argue that the greatest moral challenge of our time is serious enough to justify deliberately tampering with our climate
to stave off the damaging effects of global warming.
Geoengineering, or “climate hacking”, to use ...
A global deal to combat climate
change lurches toward reality in Lima, Peru, this week--and yet any politically feasible agreement will be insufficient to restrain continued warming of global average temperatures, perhaps uncomfortably high. ...
IN 1990 John Latham, a cloud physicist, published a short article in Nature under the headline “Control of Global Warming?” It argued that if low-lying maritime clouds were made a bit brighter, the Earth could be cooled enough to make up for the ...
The deliberate, large-scale intervention in the Earth’s climate
system is not a “quick fix” for global warming, according to the findings of the UK’s first publicly funded studies on geoengineering
The results of three projects – IAGP, ...

, which includes spraying sea salt or sulphate aerosols into the atmosphere to reflect sunlight, won’t provide a “magic bullet” to combat climate
change, a University of Oxford study shows.

At the world's first major geoengineering
conference, two separate scientists put forward proposals to use lasers to modify the Earth's climate
and fight global warming, from space.
One suggested that a satellite equipped with a ...
The Royal Society of London, the world's oldest scientific publisher, has unveiled a proposal to create the first serious framework for future geoengineering
