The All-Party Parliamentary Group for the Ocean has today released “The Ocean: Turning the Tide on Climate Change”, which examines blue carbon and ocean-based solutions to climate change. The report calls for the UK Government to prioritise and facilitate investment in blue carbon and ocean-based solutions in order to combat climate change, making several key recommendations

„In diesem Kurzimpuls geben die Autoren unter Berücksichtigung aktueller wissenschaftlicher Veröffentlichungen Antworten zu den Fragen „ist das notwendig?“, „welche Methoden sind geeignet?“, sowie „wann und wie sollten wir damit beginnen?“ Dazu versuchen sie einen Eindruck von der Größenordnung und den technischen Herausforderungen bei der Umsetzung negativer Emissionen zu vermitteln. Dieser Beitrag ist das Ergebnis einer umfangreichen Diskussion zu negativen Emissionen. Er wendet sich bewusst an Politik und die breite Öffentlichkeit. Im Vordergrund stehen daher Aspekte zu konkreten Handlungen und zu Entscheidungen.“

Organised by Smith School of Enterprise and the Environment, this webinar will launch a new global annual report The State of Carbon Dioxide Removal.
At this event, lead authors will discuss key findings from the report. They will present the global state of CDR development, tracking progress on its scale up, public perceptions, policies and innovation. After short presentations, the authors will be joined by expert contributors and will answer audience Q&A.
Presenting authors:
Special guest speaker:
The event will be chaired by Catherine Brahic, Environment Editor at The Economist.

This review summarizes the state-of-the-art negative carbon emission technologies, from the artificial enhancement of natural carbon sink technology to the physical, chemical, or biological methods for carbon capture, as well as CO2 utilization and conversion.

The U.S. Department of Energy on Tuesday agreed to commit $3.7 billion to finance projects to remove planet-warming carbon from the atmosphere and meet the nation’s goal of net-zero greenhouse gas emissions by 2050. Tuesday’s announcement formalizes a previously announced plan to finance four direct air capture hubs to draw carbon dioxide (CO2) from the air and store it underground.

In this paper, the authors compare the climate and carbon cycle consequences of carbon removal by afforestation and an equivalent fossil fuel emission reduction using simulations from an intermediate complexity Earth system model. The author’s simulations show that the climate is cooler by 0.36 °C, 0.47 °C, and 0.42 °C in the long term (2471–2500) in the case of reduced fossil fuel emissions compared to the case with afforestation when the emissions follow the SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios, respectively.
Biogeosciences opened a special issue on „Environmental impacts of ocean alkalinity enhancement, edited by Tyler Cyronak, Lydia Kapsenberg, Jaime Palter, Kai G. Schulz, and Patricia Grasse. This special issue explores a range of biological and ecological impacts associated with alkalinity enhancement and approaches for monitoring strategies in order to safely scale scientific research in the field. The target audience of this special issue includes not only the ocean alkalinity enhancement research community but also those involved in making decisions about the funding, permitting, and monitoring of potential field trials and pilot-scale studies. In keeping with our mission to publish all valid research, we consider negative and null results.

This article investigates the potential of reducing greenhouse gases in the atmosphere via the DACCS pathway, i.e., to capture CO2 from the ambient air and permanently store it in geological formations. Since the capture of CO2 from ambient air is energy-intensive, this study particularly models the integration of DACCS plants into a greenhouse gas-neutral European energy system. The model results show that DACCS in Europe 2050 could cost between 160 €/tCO2 and 270 €/tCO2 with very conservative techno-economic assumptions and between 60 €/tCO2 and 140 €/tCO2 using more progressive parameters.
The US National Oceanographic Partnership Program (NOPP) has opened a call for proposals on Marine Carbon Dioxide Removal (mCDR): Research and Development for Assessing Large Scale Carbon Removal and Local Scale Ocean Acidification Mitigation. To be eligible for this funding opportunity, each proposing team must be comprised of participants from at least two of the following three sectors:
To facilitate cross-sectoral networking and the formation of new partnerships, ClimateWorks Foundation has created a networking resource for individuals who are leading proposals and seeking new partnerships as well as individuals interested in participating in a proposal and being discoverable.
The Biochar Demonstrator Flexible Fund is open for bids to support early career researcher (ECR) gap-filling biochar projects, with awards of up to £40,000 (80% fEC) to cover salary and other research costs. All bids must be supported by an incumbent UK academic (PI). For more information please see the operational guidelines. Proposals should use the application form available on this page.
