"It is clear to us that the assessed approaches are not feasible, and that further research into these techniques would not be an effective use of limited time and resources. It is vital that these ideas do not distract from the priority to reduce greenhouse gas (GHG) emissions or from the critical need to conduct fundamental research in the polar regions."

A hard look at geoengineering reveals global risks
With CO2 emissions continuing unabated, an increasing number of policymakers, scientists and environmentalists are considering geoengineering to avert a climate catastrophe. Such interventions could influence everything from rainfall to global food supplies, making the stakes enormous.

"Underwater curtains and reflective beads are ‘unrealistic and dangerous polar geoengineering ideas’"
#Geoengineering #Climate #ClimateChange

Heh yes. Pretty much this.
"Much more will be written about proposals to build massive undersea walls to hold up Antarctic ice sheets, drill bore holes in Greenland to pump out lubricating meltwater, or scatter glass beads over glaciers. As informed and erudite I'm sure this will be, I don't think it will be as effective as simply yelling "What the hell do you think you are doing?!”"

Shortwave Absorption by Alumina Aerosol Amplifies Stratospheric Warming
Stratospheric alumina aerosols from rocket launches and geoengineering proposals are presently understood to help counteract greenhouse gas-induced warming by reflecting sunlight and cooling the lower atmosphere. Here, from direct measurement of aerosol absorption cross-sections, we report alumina's hitherto unknown shortwave absorption characteristics. Alumina's shortwave absorption could offset up to 10\% of its solar-reflective cooling, and if implemented for geoengineering, would warm the s…

Science Matters - Costly geoengineering schemes could stall real solutions
Because the fossil fuel industry and its supporters have done everything they can to stall needed solutions to the climate crisis, some people say we must now engineer our way out of the mess we created. Many are promoting schemes that block sunlight from reaching Earth, reflect more of it back into space or absorb carbon from the atmosphere.

A Planetary Cooling Hose
Geoengineering may offer a way to pause global warming, providing the time for more permanent solutions to become effective. Erection of a high-altitude hose offers an affordable and near-term approach to deliver sulfur-bearing fluids to the stratosphere in order to perform geoengineering via solar radiation management. We discuss the design of a hose extending to an altitude of 20 km and sized to deliver 100 ktons of sulfur per year. The sulfur, in the form of H$_2$S, is pushed up the hose by …

“Fake weather. Fake hurricanes. Fake flooding. Fake. Fake. Fake,” Kandiss Taylor, who intends to run as a GOP candidate to represent Georgia’s 1st congressional district in the House of Representatives, wrote in a post viewed 2.4 million times. “That doesn’t even seem natural,” Kylie Jane Kremer, executive director of Women for America First, wrote on X, in a post that has been viewed 9 million times.

What united these disparate figures is that they were all promoting the debunked conspiracy theory that the devastating flooding in Texas last weekend was caused not by a month’s worth of rain falling in the space of just a few hours—the intensity of which, meteorologists say, was difficult to predict ahead of time—but by a targeted attack on American citizens using directed energy weapons or cloud seeding technology to manipulate the weather
