Geoengineer the Planet?

By Fred Pearce on news page posted on 29 May 2019

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.

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

By Elizabeth L. Chalecki on news page posted on 17 October 2022

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.

Developing a National Strategy for Climate Engineering Research in Canada

By A. Neil Craik on news page posted on 02 November 2017

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.

The pollution paradox: How cleaning up smog drives ocean warming

By Fred Pearce, Yale Environment 360 on news page posted on 05 June 2024

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

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

By Fred Pearce on news page posted on 26 August 2024

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.

Sun block: The promise and peril of solar geoengineering

By Jeremy Hance on news page posted on 23 July 2024

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.

Geoengineering gains momentum, but governance is lacking, critics say

By Sean Mowbray on news page posted on 01 August 2024

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.

Pollution Paradox: How Cleaning Up Smog Drives Ocean Warming

By Fred Pearce on news page posted on 28 May 2024

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.

Scientists Are Trying to Coax the Ocean to Absorb More CO2

By Andrew S. Lewis on news page posted on 22 April 2024

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.

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

By Jeremy Hance on news page posted on 24 July 2024

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.

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

By Charles Pekow on news page posted on 26 August 2024

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.

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

By Sean Mowbray on news page posted on 12 August 2024

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.
