When President Trump signed a $1.4 trillion spending package in December to keep the government funded through 2020, there was a climate policy milestone buried in the budget.
For the first time ever, the government allocated funding for a federal agency to conduct geoengineering research. A line item in the National Oceanic and Atmospheric Association’s budget provides the agency with at least $4 million to study the stratosphere, the second layer of the atmosphere up from the earth. That kind of research already falls within the agency’s purview, but the language in the bill continues, “including the impact of the introduction of material into the stratosphere from changes in natural systems, increased air and space traffic, proposals to inject material to affect climate, and the assessment of solar climate interventions” (emphasis added).
For geoengineering critics, the earmark and McNerney’s bill might sound like cause for alarm. McNerney’s bill is still in early stages. The most controversial climate solution, explained. If you want to learn more about geoengineering, here’s some science resources:National Research Council.
Scientists: Let’s just spray trillions of tons of snow on Antarctica? Human-made snow isn’t just good for allowing mediocre skiing conditions to continue well into May.
It could save coastal cities around the world, like Hong Kong and New York City, from sea level rise, a new study found. In Western Antarctica, ice is breaking off into the sea faster than it’s naturally replenished by snowfall due to warming ocean currents. Is geoengineering the answer to the climate crisis?

A new study contradicts fears that using solar geoengineering to fight climate change could dangerously alter rainfall and storm patterns in some parts of the world. Manipuler les océans, une mauvaise idée pour lutter contre le changement climatique. Devil’s Bargain. A trope of sci-fi movies these days, from Snowpiercer to Geostorm, is that our failure to tackle climate change will eventually force us to deploy an arsenal of unproven technologies to save the planet.

Une implacable logique, pseudo-rationnelle et certainement pas raisonnable, pour administrer le désastre climatique et en faire le récit apparaît désormais clairement.

Marvin Herndon, Transdyne Corporation, 11044 Red Rock Drive, San Diego, CA 92131, Etats-Unis. Géoingénierie : un test pour refroidir la Terre est à l'étude. Des chercheurs de l'université de Harvard espèrent tester dans la stratosphère une expérience de géoingénierie.
L'idée est de valider cette possibilité de refroidir l'atmosphère si, un jour prochain, cette voie devenait nécessaire, et ce sans faire courir de risque au climat, à la couche d'ozone ou à la santé humaine. Ils se préparent à lancer un ballon en 2018 si tout va bien. Ce qu'il faut retenir. “More research” into geoengineering is not such a hot idea. Geoengineering is back in the news, thanks to the release of big report from the National Research Council, lending the prestige of the National Academies to the once-fringe subject. I haven’t written about the topic in a while, so … is there anything new to say? In my experience, conversations about geoengineering always go the same way. Air apparent: Once we start geoengineering, it may be hard to stop. Despite the antics of technofixers, policy wonks, and mad billionaires everywhere, geoengineering persists as an appealing-if-wacky solution to all our climate ills.
The basic logic is seductive: If we’ve messed up the climate by pumping bad stuff into the atmosphere, maybe we can undo some damage by pumping some other stuff up there, too. Of course, a minefield of potential blunders awaits the intrepid geoengineer, including wreaking havoc on rainfall or depleting polar ozone. And then there is the geopolitical factor, i.e. what may be good for China is not so good for India. A recent study [PDF] by scientists from North America, Europe, and Japan suggests another, more distant concern, and yet a vital one: What happens when we stop geoengineering?

To fight climate change, some scientists think we should vegetate the hell out of deserts. The latest such idea calls for large plantations of a hardy species of Central American tree to be planted in near-coastal desert areas and irrigated with desalinated water. While forests soak up carbon dioxide, deserts do comparatively little to help with climate change. So should these seas of sand be planted and watered out of existence in a bid to reduce CO2 levels? Some say yes. The approach would be like geoengineering, but rooted in a more natural system. The idea of replacing deserts with forests to help the climate is not brand new. The latest suggested approach, which would involve the planting of vast orchards of Barbados nut trees, technically known as Jatropha curcas trees, was proposed Wednesday by a group of German researchers in the journal Earth System Dynamics.
Les projets fous des géo-ingénieurs pour réparer le climat. Envoyer du soufre dans la stratosphère ou fertiliser les océans avec du fer : des scientifiques tentent de refroidir la planète par tous les moyens. Devant l’incapacité des nations à œuvrer ensemble dans la lutte contre le réchauffement climatique, des scientifiques ont commencé à explorer une alternative audacieuse : refroidir la planète. Substitutif ou palliatif, la géo-ingénierie regroupe les techniques qui permettraient, non pas de réduire nos émissions, mais de freiner voire inverser le dérèglement.

The Central Intelligence Agency is funding a scientific study that will investigate whether humans could use geoengineering to alter Earth’s environment and stop climate change. The National Academy of Sciences will run the 21-month project, which is the first NAS geoengineering study financially supported by an intelligence agency. Geoengineering research: Never or now?

When and Why Geo-Engineering's Crazy. Inhabitat ran a post last week entitled “5 Crazy Ways to Stop Climate Change with Geoengineering.” Some of the entries were knowingly silly (see number five: a $350 trillion lens to be built in space, for example), but others seem like the kind of thing a certain kind of politician might get behind.
Dealing with our problems via a single grand gesture has a kind of appeal, but most scientists shake their heads at these kinds of solutions. Why is that? There’s an old short story called “Watchbird” by Robert Sheckley. The heroes of his story succeed in creating a law-enforcing drone that is able to detect the particular physiological activity of an individual intent on violence against another human being and to disable an attacker. Of course, things soon go wrong.
Unforeseen and unintended Human-caused climate change is our watchbird. Consider something like an atmospheric umbrella made of airborne reflective particles, as described by David Keith in this video.
