Physics World: US geophysicists call for more work on climate intervention
On AGU statement. „More must be done to understand how the deliberate large-scale manipulation of the environment could reduce the impact of anthropogenic climate change.“

New York Times: How Big Forests Solve Global Problems
„How will we pay for a future with forest wilderness? Part of the answer lies in programs to avert climate change. A recent economic study indicates that a large share of intact forests could be preserved at a cost of $20 per ton of carbon. That’s less than half of one indicative benchmark figure: the $52 midpoint price projected by California for its regulated carbon emissions market in 2030.“

Daily Energy Insider: EPW Committee highlights support for carbon utilization, direct air capture research bill
„The Senate Environment and Public Works (EPW) Committee recently highlighted support from various stakeholders for the Utilizing Significant Emissions with Innovative Technologies (USE IT) Act, which would support carbon utilization and direct air capture research. The legislation would also support federal, state and non-governmental collaboration on the construction and development of carbon capture, utilization, and sequestration (CCUS) facilities and carbon dioxide (CO2) pipelines.“
E&P: Bipartisan Energy Legislation Highlights Benefits Of Carbon Capture
„The Utilizing Significant Emissions with Innovative Technologies Act, or USE IT Act (S. 2602), sponsored by Sen. John Barrasso (R-Wyo.) aims to encourage carbon capture, utilization and sequestration (CCUS) projects that lower emissions and to improve the permitting process for CO2 capture and infrastructure projects. As part of the effort, technology prizes would also be awarded to selected projects that capture more than 10,000 tons of CO2 annually and can be deployed for less than $200 per ton of CO2 captured.“
Climate Works Foundation: 2050 Priorities for Climate Action: Carbon Dioxide Removal is a Necessary Complement to Deep Decarbonization
„The math is clear—meeting Paris Agreement temperature goals will require not just reducing emissions but also removing them from the atmosphere. Studies suggest that by 2030 as much as 6 gigatonnes of carbon emissions needs to be captured and permanently stored each year—a target feasible with philanthropic grantmaking to catalyze investment“
PRX: Engineering Climate Solutions
Podcast. „In an emergency, we’re told to “break the glass” and grab the fire extinguisher. If we’re in the midst of a climate emergency, is there a firehose we could spray into the sky to cool down our atmosphere? It may sound like science fiction, but some climatologists endorse research into such techniques known as geoengineering. But could tinkering with the stratosphere in this way lead to a new ice age – or worse? What group of people could be trusted with such God-like powers? Join us for a discussion of the scientific, moral, economic and technological dimensions of geoengineering.“
Mengis, Nadine; et al. (2018): 1.5 °C carbon budget dependent on carbon cycle uncertainty and future non-CO2 forcing
Mengis, Nadine; Partanen, Antti-Ilari; Jalbert, Jonathan; Matthews, H. Damon (2018): 1.5 °C carbon budget dependent on carbon cycle uncertainty and future non-CO2 forcing. In Scientific reports 8 (1), p.[nbsp]5831. DOI: 10.1038/s41598-018-24241-1.
„Estimates of the 1.5 °C carbon budget vary widely among recent studies, emphasizing the need to better understand and quantify key sources of uncertainty. Here we quantify the impact of carbon cycle uncertainty and non-CO2 forcing on the 1.5 °C carbon budget in the context of a prescribed 1.5 °C temperature stabilization scenario. […] In this scenario, negative emissions would be required to compensate not only for the increasing non-CO2 climate forcing, but also for the declining natural carbon sinks.“
Project: Center for Climate Restoration
„The Center for Climate Restoration is comprised of five Working Groups and a Coordinating Council. Each Working Group has a specific topical focus: Carbon Dioxide Removal, Arctic Restoration, Finance, Narrative and Public Support, and Safety, Monitoring, and Governance. They are intended to provide a venue for experts in their respective fields to brainstorm, provide action plans, and generate momentum towards restoring the climate. The groups each have one or two leaders and a liaison to the Coordinating Council. Their first meetings will occur during the first Laudato Sí Climate Restoration Conference in Rome April 9-11, 2018, and they are expected to meet regularly thereafter to further their missions.„
Markusson, Nils; et al. (2018): Towards a cultural political economy of mitigation deterrence by Greenhouse Gas Removal (GGR) techniques
Markusson, Nils; McLaren, Duncan; Tyfield, David (2018): Towards a cultural political economy of mitigation deterrence by Greenhouse Gas Removal (GGR) techniques (AMDEG Working Paper, 1).
„This paper sets out a novel theoretical perspective to this challenge, enabling analysis that accounts for interactions between technologies, society and political and economic power. The paper argues that, seen in this light, the scope of GGRs to substitute for mitigation may be easily exaggerated, and thus that the risk of mitigation deterrence should be taken seriously. It proposes novel participative research methods designed to better reveal, evaluate, and enable effective responses to mitigation deterrence.“
