The Why, How, and Maybe Not of Geoengineering
Transcript Eliza Strickland: Man-made climate change is already reshaping our planet, and carbon emissions aren’t coming down fast enough to stave off real disaster in the decades to come. But rather than giving into despair, some engineers, poli.....»»
Emergency atmospheric geoengineering wouldn"t save the oceans
Climate change is heating the oceans, altering currents and circulation patterns responsible for regulating climate on a global scale. If temperatures dropped, some of that damage could theoretically be undone......»»
Viewpoint: Without more research and guardrails, geoengineering is a costly gamble, with potentially harmful results
When soaring temperatures, extreme weather and catastrophic wildfires hit the headlines, people start asking for quick fixes to climate change. The U.S. government just announced the first awards from a US$3.5 billion fund for projects that promise t.....»»
Could artificially dimming the sun prevent ice melt?
With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Bernese researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artifici.....»»
A Sun Shield over Earth? Catch an Asteroid, and It Might Work
A resurfaced idea for solar geoengineering imagines a sunlight-blocking space shield tethered to an asteroid.....»»
Q&A: Experts discuss the geoengineering methods for reflecting sunlight to cool Earth
As concerns about climate change intensify, researchers are exploring the potential for large-scale human intervention in the Earth's climate system, a strategy sometimes referred to as geoengineering. One approach to cooling the Earth involves sunli.....»»
Opinion: Geoengineering is shockingly inexpensive
Despite decades of warnings and international climate agreements, global carbon emissions are still rising. Carbon emissions seem like an unstoppable juggernaut as energy-hungry humans keep breeding and pursuing more affluent lifestyles. Reducing emi.....»»
Geoengineering Is Not a Quick Fix for the Climate Crisis, New Analysis Shows
A new study debunks the idea that solar geoengineering is a temporary measure to reduce warming and meet climate targets.....»»
Old Bomber Plane Will Sniff the Sky for Geoengineering Particles
NOAA will use a converted Air Force bomber to search the upper atmosphere for substances that could help the U.S. reflect sunlight away from Earth.....»»
Solar Geoengineering Should Be Regulated, U.N. Report Says
A panel of independent experts urged international leaders to set rules for the stratosphere and solar geoengineering.....»»
Social media posts around solar geoengineering "spill over" into conspiracy theories
Researchers from the University of Cambridge have analyzed more than 800,000 tweets and found that negative emotions expressed about geoengineering—the idea that the climate can be altered using technology—can easily fall into conspiracy......»»
Startup claims to offer stratospheric geoengineering as a service
Claims to sell geoengineering warming offsets but can't currently validate anything. Enlarge / Stratospheric aerosols can make for great sunsets, regardless of how they get there. (credit: Rachel Dulson) Humanity has man.....»»

Solar geoengineering might work, but local temperatures could keep rising for years
Imagine a future where, despite efforts to reduce greenhouse gas emissions quickly, parts of the world have become unbearably hot. Some governments might decide to "geoengineer" the planet by spraying substances into the upper atmosphere to form fine.....»»
The Nightmare Politics and Sticky Science of Hacking the Climate
Spraying aerosols and sucking carbon out of the air would bring down temperatures, yes. But the unintended consequences of geoengineering could be enormous......»»
Geoengineering could return risk of malaria for one billion people
Geoengineering the climate would have massive repercussions for the health of billions of people at risk of malaria who live in tropical countries, according to a new finding by scientists at Georgetown University Medical Center and colleagues. The s.....»»
New research study: "Sky is not the limit" for solar geoengineering
There are practical limits to the height at which aerosols may be deployed in the atmosphere to deflect incoming sunlight and countervail global warming. Very high-altitude injections might be more effective, but such climate intervention comes with.....»»
Think Climate Change Is Messy? Wait Until Geoengineering
Someone's bound to hack the atmosphere to cool the planet. So we urgently need more research on the consequences, says climate scientist Kate Ricke......»»
Before geoengineering to mitigate climate change, researchers must consider some fundamental chemistry
It's a tempting thought: With climate change so difficult to manage and nations unwilling to take decisive action, what if we could mitigate its effects by setting up a kind of chemical umbrella—a layer of sulfuric acid in the upper atmosphere that.....»»
Neal Stephenson Discusses His New Climate Change Thriller - and Coining the Word "Metaverse"
Tonight CNBC interviewed science fiction luminary Neal Stephenson about his new "geoengineering climate change thriller" — and about his coining of the original term "metaverse." Author Neal Stephenson shot to fame almost 30 years ago with the.....»»
In Science magazine, scholars call for more comprehensive research into solar geoengineering
Two articles being published in Science magazine's influential Policy Forum this week argue for more and better social science research into the potential use of solar geoengineering to offset some of the global warming from greenhouse gases in the a.....»»
