Prospects for mitigating sea level rise by slowing flows of glacial ice into the ocean are worthy of research, but this work must involve all rights holders and stakeholders.

As ‘Doomsday’ Glacier Melts, Can an Artificial Barrier Save It?

26 August 2024, Fred Pearce, e360.yale.edu

Relatively warm ocean currents are weakening the base of Antarctica’s enormous Thwaites Glacier, whose demise could raise sea levels by as much as 7 feet. To separate the ice from those warmer ocean waters, scientists have put forward an audacious plan to erect a massive underwater curtain.

Will we be ready? Geoengineering policy lags far behind pace of climate change

26 August 2024, Charles Pekow, news.mongabay.com

The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.

This simple farming technique can capture carbon for thousands of years

22 August 2024, Matt Simon, grist.org

Across the world, farmers are turning waste biomass into biochar, improving soils, boosting yields, and creating a new source of income.

Cloud brightening over oceans may stave off climate change, but with risk

12 August 2024, Sean Mowbray, news.mongabay.com

Marine cloud brightening (MCB), the spraying of sea salt aerosols or other fine particles into clouds to artificially brighten them and increase the sun’s reflectivity, is a proposed strategy to ward off the full effects of climate change.

Geoengineering gains momentum, but governance is lacking, critics say

01 August 2024, Sean Mowbray, news.mongabay.com

As the climate crisis advances, geoengineering — intentionally modifying Earth systems on a large scale to cool the planet or store additional carbon — is increasingly a hot topic. But an intense debate is raging as to how to govern research and deployment of these deeply contentious strategies.

Don’t even study it: Geoengineering research hits societal roadblocks

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

As climate change accelerates, some scientists are calling for more field research into solar geoengineering concepts. However, these ideas are running into opposition from other researchers, some governments and the public.

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

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.
