# Article Nature-based and geo-engineering climate mitigation technologies: Public acceptance and security prospects. Public attitudes strongly favor nature-based climate solutions like reforestation. Sociodemographic factors like education and region shape climate-tech perceptions. Logistic regression models show public support for varied climate mitigation methods. Climate change requires mitigation approaches, from nature-based to experimental geoengineering. We examined public attitudes toward six strategies—reforestation in previously forested areas, afforestation in new terrains, direct CO2 capture with underground storage, biomass energy with CO2 capture, stratospheric sulfate aerosols, and orbital mirrors—via a representative Czech survey (*N* = 3,007). Results show strong favor for reforestation and afforestation due to ecological benefits and long-term promise; sulfate aerosols and orbital mirrors face skepticism. Older respondents favored biomass-based carbon capture but less so certain high-tech solutions. Our findings highlight the importance of policies aligned with diverse public views, ensuring both established and novel measures are harmonized into an effective climate mitigation strategy. These results indicate demographic contexts shape acceptance of climate interventions.

In our civilization’s effort to slow down and stop Climate Change and reverse Global Warming, geoengineering should not be considered the only solution, but rather an important part of a comprehensive, integrated, international program that mitigates the effects of Global Warming, restores our biosphere and addresses the root causes of Climate Change (i.e., the use of fossil fuels and carbon dioxide emissions, human population growth, consumptive lifestyles, unsustainable practices, degradation of natural ecosystems, etc.).

# Geoengineering 101. One characteristic that is common to the geoengineering approach is the belief that we can use technology to reverse or detain climate change without having to cut carbon emissions by eliminating fossil fuel use. ## **Geoengineering Experiments**. Several dangerous geoengineering experiments are already underway, with potentially dire consequences for the earth. In May 2020, a small group of Australian geoengineers3 carried out a risky geoengineering technique – brightening clouds to reflect solar energy back into space – and presented it as a plan to save the Great Barrier Reef. The experiment contravenes the UN Convention on Biodiversity, which in 2010, established a moratorium on geoengineering activities until “a global, transparent and effective control and regulatory mechanisms… in accordance with the precautionary approach can be put in place.”5. The proposed Ice911 Project wants to experiment on Inupiaq and Gwich’n territories in the Arctic region by polluting the ice and oceans with tiny glass beads.

# Need To Know: Geoengineering and Cloud Seeding. No comments on Need To Know: Geoengineering and Cloud Seeding. Techniques to deliberately alter Earth’s climate, such as geoengineering and cloud seeding, have been in the news following the devastating floods in Texas. Lamb, an associate research scientist in the Department of Earth and Environmental Engineering at Columbia University, introduces the science underlying geoengineering and weather modification and discusses their implications for future climate mitigation strategies. Another set of methods, referred to under the umbrella of Solar Radiation Management (SRM), aim to increase the reflection of sunlight from the Earth’s atmosphere in order to cool the Earth’s climate. The most studied of these methods is stratospheric aerosol injection, which proposes to put sulfate aerosols high up in the Earth’s atmosphere to cool the climate (this is similar to the cooling effect that is observed after a large volcanic eruption, such as Mount Pinatubo in 1991). atmospheric science, climate change, cloud seeding, geoengineering, Kara D.

# Geoengineering: Building ethics, transparency and inclusion into climate intervention research. Geoengineering or climate intervention aims to tackle global warming through large-scale interventions in Earth’s climate system.Image: iStockphoto/AleksandarGeorgiev. * The urgency of the climate crisis has boosted interest in climate intervention or geoengineering – large-scale interventions to counteract global warming. Climate intervention, also known as geoengineering, is the deliberate large-scale intervention in Earth’s climate system to counteract global warming. On 22 October 2024, the American Geophysical Union (AGU) released its Ethical Framework Principles for Climate Intervention Research as a guide to responsible decision-making and inclusive dialogue about geoengineering research. Two leading concepts in climate intervention research – carbon dioxide removal and solar radiation modification – are defined and addressed in the framework, but the principles are broad and flexible by design so they can be applied to all emerging research. AGU developed these framework principles through a two-year process that included an open public comment period and contributions from a global board of scientists, policymakers, ethicists, government agencies, nongovernmental organizations and representatives of potentially impacted communities including Indigenous peoples.

However, research shows that using solar geoengineering could indirectly lower the amount of CO2 in the atmosphere by stemming permafrost melt, reducing energy-sector emissions and causing changes to the carbon-cycle feedback. Aerosol injection could have an edge on other proposed forms of solar geoengineering because it would not require a large technological leap to become a reality, Jones says:. These brighter clouds would reflect away more sunlight, says Prof Douglas MacMartin, an engineering researcher from Cornell University, who contributed to the US House of Representatives’ hearing on geoengineering. Earlier this month, MacMartin, Keith and Prof Katharine Ricke, a climate scientist from the University of California, San Diego, published a research paper exploring how solar geoengineering – via releasing aerosols into the stratosphere – could be used as part of an “overall strategy” for limiting global warming to 1.5C, which is the aspirational target of the Paris Agreement. However, the researchers point out that using solar geoengineering to hold global warming to 1.5C would not have the same environmental effect as reaching the target using mitigation.
