Geoengineering & Weather Control News and Discussions

Give research into solar geoengineering a chance
By at least one measure, US President Joe Biden’s online climate summit last month was a success: several governments, including that of the United States, made fresh pledges to reduce greenhouse-gas emissions. Combined with earlier announcements from other countries and the European Union, these pledges would reduce emissions in 2030 by the equivalent of more than 3 billion tonnes of carbon dioxide, more than the current annual carbon emissions of India. But even this reduction — if achieved — would not be enough for the world to remain on a plausible path to limit warming to 1.5 °C relative to pre-industrial times.

World leaders must look for ways to close that gap at the United Nations climate convention in Glasgow, UK, in November, and then implement their commitments. Clearly there is a long and difficult road ahead. So governments and scientists must continue evaluating carbon capture and other climate strategies that can be used to remove carbon dioxide from the atmosphere. They should also explore solar geoengineering, which involves altering clouds or adding reflective particles to the stratosphere to reflect sunlight back into space and cool the planet. The effect of such stratospheric injections would be similar to the cooling that happens after volcanic eruptions.

Some studies suggest that solar geoengineering could provide much-needed short-term relief if global warming becomes unbearable

Solar Geoengineering: The Case for an International Non-use Agreement
January 17, 2022

https://wires.onlinelibrary.wiley.com/d ... 02/wcc.754

Abstract:
(Wiley Interdisciplinary Review) Solar geoengineering is gaining prominence in climate change debates as an issue worth studying; for some it is even a potential future policy option. We argue here against this increasing normalization of solar geoengineering as a speculative part of the climate policy portfolio. We contend, in particular, that solar geoengineering at planetary scale is not governable in a globally inclusive and just manner within the current international political system. We therefore call upon governments and the United Nations to take immediate and effective political control over the development of solar geoengineering technologies. Specifically, we advocate for an International Non-Use Agreement on Solar Geoengineering and outline the core elements of this proposal.
Should the World Ban Solar Geoengineering?

Conclusion:
(Grist) The prospect of dimming the sun to combat global warming has been in discussion for almost as long as climate change itself. The first report on global warming that was handed to a U.S. president — Lyndon Johnson in 1965 — suggested it as a way to halt rising temperatures without stopping the use of fossil fuels. And in the past few years, attention to the concept has grown. Last year, the U.S. National Academies of Science created a plan for a research program that would investigate the idea, and a Harvard project planned to test a solar geoengineering balloon in Kiruna, Sweden. (The test flight was halted after backlash from Swedish indigenous communities.)

Critics of the technology argue that it could create a moral hazard: that is, if solar geoengineering becomes an option, the world might not try so hard to reduce greenhouse gas emissions, the actual underlying cause of global warming. Companies heavily invested in fossil fuels could also use it as an excuse to avoid reducing the use of oil and gas.

The writers of the open letter (see opening article of this post) argue that solar geoengineering could cause uneven impacts around the globe — potentially affecting local weather patterns or food supply. What’s more, they suggest that the new technology is effectively “ungovernable.” If one country decides to spray aerosols into the atmosphere, the repercussions will affect the entire globe, whether the residents of poor countries have agreed to it or not. The deployment of solar geoengineering, they write, would require creating international organizations with “unprecedented enforcement powers” that don’t yet exist.

But other researchers have argued that solar geoengineering may be necessary to research — even if it is never deployed. Some have critiqued the open letter as an attempt to stifle scientific progress, or have argued that further research could eventually be useful to countries who face the worst impacts of climate change — heat, extreme weather, and drought.

Holly Jean Buck, a professor at the University of Buffalo and an expert in geoengineering, wrote on Twitter: “Can you not imagine someone in, say, 2050, who is suffering from extreme heat, wondering why their parents’ generation decided to forbid research on something that might be able to cool the climate and save them from a dangerous heat wave?”

Its nice to see that this is an actual topic. I imagine making sure the world doesn't heat up easily must be quite a lot of work.

Now solar geoengineering sounds so cool! And considering the amount of technology in orbit it is a natural logical consideration.

Researchers report game-changing technology to remove 99% of carbon dioxide from air
https://techxplore.com/news/2022-02-gam ... e-air.html
by Karen B. Roberts, University of Delaware

University of Delaware (UD) engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen.

It is a significant advance for carbon dioxide capture and could bring more environmentally friendly fuel cells closer to market.

The research team, led by UD Professor Yushan Yan, reported their method in Nature Energy on Thursday, February 3.

Game-changing tech for fuel cell efficiency

Fuel cells work by converting fuel chemical energy directly into electricity. They can be used in transportation for things like hybrid or zero-emission vehicles.

Yan, Henry Belin du Pont Chair of Chemical and Biomolecular Engineering at UD, has been working for some time to improve hydroxide exchange membrane (HEM) fuel cells, an economical and environmentally friendly alternative to traditional acid-based fuel cells used today.

Research shows carbon dioxide could be stored below ocean floor
https://phys.org/news/2022-03-carbon-di ... floor.html
by National University of Singapore

Climate change is one of the most pressing challenges facing humanity. To combat its potentially catastrophic effects, scientists are searching for new technologies that could help the world reach carbon neutrality.

One potential solution that is drawing growing attention is to capture and store carbon dioxide (CO2) emissions in the form of hydrates under ocean floor sediments, kept in place by the natural pressure created by the weight of the seawater above. A major question, however, has been how stable this stored CO2would be for the extended periods of storage required to keep the carbon in place and out of the atmosphere.

Now researchers from the National University of Singapore's Department of Chemical and Biomolecular Engineering, have demonstrated the first-ever experimental evidence of the stability of CO2 hydrates in oceanic sediments—an essential step in making this carbon storage technology a viable reality.

"It's the first of its kind experimental evidence that we hope is going to spur further activity on this technology development," said Professor Praveen Linga, the lead researcher of the study. The team's findings—part of a project funded through the Singapore Energy Centre—were first published in scientific journal Chemical Engineering Journal.

Scientists Want to Refreeze Polar Regions by Pumping Dust into Atmosphere
by Tom Hale
September 16, 2022

Introduction:
(IFL Science) Scientists have floated the idea of refreezing the North and South poles by pumping the Earth’s atmosphere with microscopic particles to block out the sunlight. This, they say, is a “feasible and remarkably cheap” way to avert some of the impacts of the climate crisis – although they admit it comes with some risks.

Setting out the plan in a new study, the idea is to use a fleet of 125 high-altitude military aircraft to release aerosol particles into the stratosphere in both the Northern and Southern Hemispheres.

If injected at a height of 13,106 meters (43,000 feet) at a latitude roughly the same as Anchorage in southern Alaska and the southern tip of Patagonia, then the particles would drift towards the poles and shade the surface beneath from sunlight.

Less solar energy means less heat. If done correctly, the researchers argue this could drop the temperature in the polar regions by 2°C (3.6°F), roughly the same as pre-industrial levels. In turn, lower global temperatures would also be fostered.

"Game-changing though this could be in a rapidly warming world, stratospheric aerosol injections merely treat a symptom of climate change but not the underlying disease. It's aspirin, not penicillin. It's not a substitute for decarbonization," Wake Smith, lead study author and an expert in geoengineering from Yale University, said in a statement.

This is pretty drastic, but seems inevitable. Once the Arctic sea ice is gone, likely by 2040 or sooner, we'll have climate change on steroids.

Company releases sulfur into atmosphere to combat climate change

Post by PineappleDuckCurry »

A startup says it has begun releasing sulfur particles into Earth’s atmosphere, in a controversial attempt to combat climate change by deflecting sunlight. Make Sunsets, a company that sells carbon offset “cooling credits” for $10 each, is banking on solar geoengineering to cool down the planet and fill its coffers. The startup claims it has already released two test balloons, each filled with about 10 grams of sulfur particles and intended for the stratosphere, according to the company’s website and first reported on by MIT Technology Review.

Could Space Dust Help Protect the Earth from Climate Change?
February 8, 2023

Introduction:
(EurekAlert) Cambridge, Mass. – On a cold winter day, the warmth of the sun is welcome. Yet as humanity emits more greenhouse gases, the Earth's atmosphere traps more and more of the sun's energy, which steadily increases the Earth's temperature. One strategy for reversing this trend is to intercept a fraction of sunlight before it reaches our planet.

For decades, scientists have considered using screens or other objects to block just enough of the sun’s radiation — between 1 or 2 percent — to mitigate the effects of global warming. Now, a new study led by scientists at the Center for Astrophysics | Harvard & Smithsonian and the University of Utah explores the potential of using dust to shield sunlight.

The paper, published today in the journal PLOS Climate, describes different properties of dust particles, quantities of dust and the orbits that would be best suited for shading Earth. The team found that launching dust from Earth to a way station at the “Lagrange Point” between Earth and the sun would be most effective but would require an astronomical cost and effort.

The team proposes moondust as an alternative, arguing that lunar dust launched from the moon could be a low-cost and effective way to shade the Earth.

"It is amazing to contemplate how moon dust — which took over four billion years to generate — might help slow the rise in the Earth’s temperature, a problem that took us less than 300 years to produce,” says study co-author Scott Kenyon of the Center for Astrophysics.
