„Wir brauchen viel mehr Energie, als wir bisher dachten“, sagt OpenAI-Chef Sam Altman. Er meint, die Menschheit müsse „etwas Dramatisches“ tun, um das Klima zu schützen und den Energiebedarf von „KI“ zu decken.
Given that the serious impacts of climate change are rapidly escalating, some scientists, backed up increasingly by governments, are looking into extreme measures such as geoengineering to slow the rate of change.
A new report examines 61 climate mitigation ideas for the Arctic, including geoengineering.
It's not possible to simultaneously make scientifically relevant assertive statements about #ClimateChange while pretending #chemtrails and #geoengineering aren't real.
If your model doesn't take these aspects of man-made weather modification into account, it's wrong!
Einige glauben, wir könnten mit #Geoengineering das Thermostat zurückdrehen und die #Klimakrise wäre vorbei. Dabei haben all diese Technologien mehr Risiko als Nutzen.
Warum wetten Menschen auf Erfindungen, die uns auf wundersame Weise retten? Wir haben doch Erneuerbare Energien! https://youtube.com/shorts/1-vB86wf80o
How to Build a Climate Bomb
By Richard Heinberg, orig pub by Resilience.org April 8, 2024
“Once started, solar geoengineering cannot be stopped. Assuming that carbon emissions continued, the artificial sunshade would mask increasing amounts of...warming. If geoengineering ceased abruptly—due to sabotage, technical, or political reasons—temperatures would shoot up rapidly. This termination shock would be catastrophic for humans & ecosystems.”
...How awful might a geoengineering termination shock...be?
Think of climate change as a wildfire. An uncontrolled burn releases energy previously held in trees and grasses, adding it to the local environment in the form of heat. Similarly, by trapping solar radiation, greenhouse gases add energy in the form of heat to the global climate system...
In contrast, a sudden release of pent-up warming would metaphorically more closely resemble a bomb, whose explosion releases energy far faster..."
So in der Art sähe der #Himmel übrigens dauerhaft aus, sollte die Menschheit in Zukunft aus #Klimakrise-Not zum #geoengineering mit kühlenden Aerosolen greifen müssen.
GOP lawmakers are fueling a conspiracy theory without mentioning ‘#chemtrails’
"Republican state lawmakers are going after a new threat they say could cause harm to the environment — and playing into a baseless claim at the same time.
“Between half and two-thirds of discourse online on [#geoengineering] is conspiratorial,” Wagner said. “That is unfortunate, because there are real pollution problems out there.”"
"Various government research arms are already gaming out scenarios, looking at who might decide to carry out climate engineering and how.
Once #ClimateEngineering is deployed, countries may be more likely to blame climate engineering for extreme events such as hurricanes, floods and droughts, regardless of the evidence.
Climate engineering may spark conflicts among countries."
"Starting and then stopping solar #geoengineering would cause the warming that had been temporarily held in abeyance to show up quickly and with a vengeance.
To me, the failure of humanity to maintain a solar radiation geoengineering project, once it has started, is not a remote risk; rather, it’s the most likely thing that would happen."
'Termination shock'
For decades we already DID #GeoEngineering, through sun-dimming air pollution from, e.g. shipping. Recently, we tackled that that pollution, reducing it by a large amount.
Yay! cleaner air.
But:
"Sudden cut in pollution in 2020 meant less shade from sun and was ‘substantial’ factor in record surface temperatures in 2023, study finds."
"The heating effect of the pollution cut is expected to last about seven years."
The UN 🇺🇳 enviro agency chief has warned that a rush into experimental techniques to cool the atmosphere by partially blocking the sun risked harming wildlife, oceans, the ozone layer & crops, after failure by govts to agree how to control #geoengineeringhttps://buff.ly/3wIU9Ip
"About 10% of the particles floating around the stratosphere now come from the aerospace industry, and we don't know if this could impact the climate."
The debate over whether to let people launch particles into the sky that would reflect sunlight back into space has been tabled after talks at the UN Environmental Assembly ended in a stalemate. @verge has more on the countries that tried and failed to establish tougher ground rules on solar geoengineering. https://flip.it/ugYSJr #Science#ClimateChange#UN#Geoengineering
I like having backup plans, and that's what geoengineering is.
The better plan is the one we all know, the simpler one that oligarch owned governments keeping ignoring and fascist owned farmers keep whining about.
What deep held flaw is built into the human psyche that we would prefer to consider the monstrous technologies of #geoengineering rather than cut any fossil fuel use?
Scientists Resort to Once-Unthinkable Solutions to Cool the Planet. Three #geoengineering projects seek to alter the chemistry of the atmosphere and the ocean. Critics warn of unintended consequences. #climatechange
A US engineer had a shocking plan to improve the climate – burn all coal on Earth
"Several generations ago, it simply hadn't yet sufficiently occurred to scientists that #ClimateChange might unleash significant harms. Now it's overwhelmingly accepted. It's likely we are missing similarly vital insights today, insights that would enable us to navigate our world far more wisely."
Because the answer is never 'just consume less': "It’s come to this. With Earth at its hottest point in recorded history, and humans doing far from enough to stop its overheating, a small but growing number of astronomers and physicists are proposing a potential fix that could have leaped from the pages of science fiction: The equivalent of a giant beach umbrella, floating in outer space."
If we live in a "solutionist age" (remember: E. Morozov), why are technological solutions to the climate issue ( #geoengineering e.g. direct air capture) so unpopular (meaning: at least in Germany, I don't see any significant public support)?
