Sun block: The promise and peril of solar geoengineering

23 July 2024, Jeremy Hance, news.mongabay.com

Recent research and interest, especially from the U.S. government, has pushed a solar geoengineering idea known as SAI, or stratospheric aerosol injection, to the top of lists of potential ideas to cool the planet. SAI would use fleets of high-flying aircraft to disperse sunlight-reflecting particles, including sulfates, into the stratosphere.

The pollution paradox: How cleaning up smog drives ocean warming

05 June 2024, Fred Pearce, Yale Environment 360, grist.org

New research indicates that the decline in smog particles from China’s air cleanups caused the recent extreme heat waves in the Pacific.

Pollution Paradox: How Cleaning Up Smog Drives Ocean Warming

28 May 2024, Fred Pearce, e360.yale.edu

New research indicates that the decline in smog particles from China’s air cleanups caused the recent extreme heat waves in the Pacific. Scientists are grappling with the fact that reducing such pollution, while essential for public health, is also heating the atmosphere.

Report ranks 60+ ideas, including geoengineering, to save the Arctic

21 May 2024, Jeremy Hance, news.mongabay.com

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.

Scientists Are Trying to Coax the Ocean to Absorb More CO2

22 April 2024, Andrew S. Lewis, e360.yale.edu

For billions of years, the oceans have been absorbing CO2 from the atmosphere. Now, to boost that drawdown, startup companies and researchers are experimenting with ‘marine carbon dioxide removal’ by altering the chemistry of the ocean and sinking biomass to the seafloor.

Pumped up: will a Dutch startup’s plan to restore Arctic sea-ice work?

27 February 2024, Senay Boztas, www.theguardian.com

As the Arctic warms, devastating the climate and ecosystems, an old idea used to create skating rinks could be deployed to restore melting ice caps, despite scepticism from some experts

Switzerland calls on UN to explore possibility of solar geoengineering

22 February 2024, Jonathan Watts , www.theguardian.com

Proposal focuses on technique that fills atmosphere with particles, reflecting part of sun’s heat and light back into space

How air pollution delayed a surge in extreme rain

22 February 2024, Jake Bittle, grist.org

Aerosol pollutants have masked the effects of global warming. Without them, the U.S. is about to get a lot wetter.

Some scientists say blocking the sun could slow climate change — just like on The Simpsons

12 September 2023, CBC, www.cbc.ca

Scientists say geoengineering, or doing things like intentionally increasing Earth’s reflectivity or blocking the sun, is a “really big deal” in slowing down climate change. Here are the ideas they are proposing.

Could Canada lead the formation of a new global geoengineering regime?

17 October 2022, Elizabeth L. Chalecki, doi.org

As the effects of climate change continue to worsen, nations will have the opportunity to develop and deploy climate manipulation techniques known as geoengineering to forestall the worst effects. Indeed, some have argued that the nations of the world cannot meet their Paris Agreement goals without them. However, these technologies can be global in their effects, ecologically uncertain, and potentially prejudicial to non-deploying nations. Canada is well suited to lead the formation of an anticipatory governance regime due to its technological knowledge, the proximity of the Arctic as a potential testing ground, and its role as an internationally respected middle power. By stepping forward to lead the effort, Canada can ensure its own security and environmental interests as well as the stability of the rules-based international order.

Geoengineer the Planet?

29 May 2019, Fred Pearce, e360.yale.edu

Human intervention with the climate system has long been viewed as an ill-advised and risky step to slow global warming. But with carbon emissions soaring, initiatives to study and develop geoengineering technologies are gaining traction as a potential last resort.

Developing a National Strategy for Climate Engineering Research in Canada

02 November 2017, A. Neil Craik, www.cigionline.org

Climate engineering (CE) is increasingly becoming an area of broad public policy interest within international and domestic climate policy discussions. In addition to receiving greater attention within regulatory contexts, there is a gradual shift toward greater support for nationally supported research programs on CE technologies and assessments. Despite the increased salience of CE, the issue has been largely absent from the Canadian public policy agenda. This paper argues that a national strategy for CE research ought to be developed as part of Canada’s broader climate strategy. At the centre of this strategy must be a commitment to ensuring a high level of public trust in the underlying science and a policy process that is open and responsive to public views.
