More Than 90 Scientists Write Open Letter Encouraging Study of Geoengineering to Cool Planet

More than 90 scientists from around the world have written an open letter recommending that research be done on the potential of increasing solar radiation modification (SRM) — the reflection of sunlight away from Earth’s atmosphere, sometimes referred to as “solar geoengineering” — in order to slow planetary warming and lessen climate impacts. The scientists […]

    Seven Key Things to Know About ‘Negative Emissions’

    Seven Key Things to Know About ‘Negative Emissions’

    By Jan Minx, Dr. Sabine Fuss and Gregory Nemet Despite the ambitious long-term climate goals of the Paris agreement, there remains a distinct lack of success at ushering in immediate and sustained reductions in global CO2 emissions. This cognitive dissonance has seen the topic of “negative emissions“—also known as “carbon dioxide removal”—move into the limelight […]

    Solar Geoengineering: Risk of ‘Termination Shock’ Overplayed, Study Says

    Solar Geoengineering: Risk of ‘Termination Shock’ Overplayed, Study Says

    By Robert McSweeney Solar geoengineering, or “solar radiation management” (SRM), is perhaps the most controversial of the different ways of limiting human-caused climate change. A commonly voiced objection to the technique is the risk of “termination shock”—the rapid rebounding of global temperatures if SRM is deployed and then suddenly stopped. But a new research article, […]

    Geoengineering Carries ‘Large Risks’ for the Natural World, Studies Show

    Geoengineering Carries ‘Large Risks’ for the Natural World, Studies Show

    By Daisy Dunne Reducing the impacts of human-caused climate change through the use of bioenergy with carbon capture and storage—better known as BECCS—could have major consequences for wildlife, forests and water resources, a new study shows. The large-scale conversion of existing land to BECCS plantations could cause global forest cover to fall by as much […]

    Geoengineering Could Create More Problems Than It Could Solve

    Geoengineering Could Create More Problems Than It Could Solve

    By Tim Radford Geoengineering—the untested technofix that would permit the continued use of fossil fuels—could create more problems than it could solve. By masking sunlight with injections of sulphate aerosols in the stratosphere, nations could perhaps suppress some of the devastating hurricanes and typhoons that in a rapidly warming world threaten northern hemisphere cities. But […]

    Climate Denier Lamar Smith: Geoengineering Can Curb Impacts of Climate Change

    Climate Denier Lamar Smith: Geoengineering Can Curb Impacts of Climate Change

    By Steve Horn Geoengineering, hailed in some circles as a potential techno-fix to the climate change crisis, has taken a step closer to going mainstream. The U.S. House Committee on Science, Space and Technology held a rare joint subcommittee hearing on Nov. 8, only the second ever congressional hearing of its kind on the topic […]

    ‘Geostorm’ Movie and Climate Hacking: Are the Dangers Real?

    ‘Geostorm’ Movie and Climate Hacking: Are the Dangers Real?

    By Jane A. Flegal and Andrew Maynard Hollywood’s latest disaster flick, “Geostorm,” is premised on the idea that humans have figured out how to control the earth’s climate. A powerful satellite-based technology allows users to fine-tune the weather, overcoming the ravages of climate change. Everyone, everywhere can quite literally “have a nice day,” until—spoiler alert!—things […]

    Is Geoengineering the Answer to Limit Global Warming?

    Is Geoengineering the Answer to Limit Global Warming?

    By Tim Radford Geoengineering, the deliberate alteration of the planet to undo its inadvertent alteration by humans over the past 200 years, is back on the scientific agenda, with a climate compromise suggested as a possible solution. One group wants to turn down the global thermostat and reverse the global warming trend set in train […]
