Event participants

Tenzin Wangmo, Lead Negotiator of the Least Developed Countries (LDC) Group 
Mattias Frumerie, Director at the Swedish Ministry for Foreign Affairs
Rachel Ward, Programme Director and Head of Policy at the Institutional Investors Group on Climate Change
Iseoluwa Akintunde, Mo Ibrahim Academy Fellow at Chatham House
Chair: Kirsty Hamilton, Associate Fellow, Chatham House

Finance plays a key role in enabling climate change mitigation and adaptation. It is also a contested issue in the UN climate negotiations. The fourth event in the Chatham House COP26 Diplomatic Briefing Series will explore the politics of climate finance in the context of the COP, and provide a comprehensive update of the main climate finance-related negotiation items and processes. The topic is particularly timely given that the UK Government has made climate finance one of its top thematic priorities for COP26 and that 2020 constitutes the deadline for developed countries to mobilise USD 100 billion per year to support climate action in developing countries.

Extreme weather, rising sea levels and a melting Arctic - the effects of climate change are posing an increasingly large threat to national security worldwide. Although the issue has gained traction within the international community in recent years, including within the UN Security Council, it is urgent that governments act more decisively to mitigate and respond to the threat, not least given that climate change is happening faster and in a more powerful way than originally anticipated.
 
The third event in the Chatham House COP26 Diplomatic Briefing Series – 'Climate Change and National Security' - will analyze how climate change acts as a threat multiplier, fuelling instability and endangering economic, social and political systems across the globe. The briefing will also provide recommendations of what governments and other stakeholders should do to develop effective responses.

Biology of Lipid Rafts: Introduction to the Thematic Review Series [Thematic Reviews]

Lipid rafts are organized plasma membrane microdomains, which provide a distinct level of regulation of cellular metabolism and response to extracellular stimuli, affecting a diverse range of physiologic and pathologic processes. This Thematic Review Series focuses on Biology of Lipid Rafts rather than on their composition or structure. The aim is to provide an overview of ideas on how lipid rafts are involved in regulation of different pathways and how they interact with other layers of metabolic regulation. Articles in the series will review the involvement of lipid rafts in regulation of hematopoiesis, production of extracellular vesicles, host interaction with infection, and the development and progression of cancer, neuroinflammation, and neurodegeneration, as well as the current outlook on therapeutic targeting of lipid rafts.

11C-choline PET/CT in recurrent prostate cancer: retrospective analysis in a large US patient series

Purpose: To evaluate 11C-choline PET/CT detection performance for biochemically recurrent prostate cancer (PCa) in a large non-European cohort in the context of emerging evidence for PSMA PET in this setting, and to map patterns of PCa recurrence. Methods: We retrospectively analyzed 11C-choline PET/CT scans from 287 patients who were enrolled onto an imaging protocol based on rising prostate-specific antigen (PSA) levels (mean:3.43 ng/mL, median:0.94 ng/mL, range:0.15–89.91) and suspected recurrent PCa. A total of 187 patients had undergone primary radical prostatectomy (RP; 79/187 had secondary radiotherapy), 30 had undergone primary radiotherapy (RT), and 70 had persistent PSA elevation after receiving initial treatment (69 post-RP, 1 post-RT). The level of suspicion for recurrence on 11C-choline PET/CT was scored (0:negative, 1:equivocal, 2:positive) by two readers. The correlation between 11C-choline PET/CT positivity and initial treatment, Gleason score, NCCN stage, PSA level, PSA doubling time, PSA velocity, and time between initial treatment and PET imaging was evaluated. Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE) criteria were used to map 11C-choline recurrence patterns. Results: Considering scores 1 and 2 as positives, consensus between the two readers deemed 66% of the 11C-choline PET/CT scans as positive. When sorted by PSA level, 45% of patients with PSA<0.5 ng/mL, 56% of patients with PSA 0.5–0.99 ng/mL, 70% of patients with PSA 1.0–1.99 ng/mL, and 90% of patients with PSA ≥2.0 ng/mL scored either 1 or 2 on 11C-choline PET/CT scans. When considering scores of 2 only, 11C-choline PET/CT positivity was 54% (28%, 46%, 62%, and 81%, respectively, for patients with PSA <0.5 ng/mL, 0.5–0.99 ng/mL, 1.0–1.99 ng/mL, and ≥2.0 ng/mL). In multivariate analysis, only the PSA level was significantly associated with scan positivity. Pattern analysis showed that pelvic lymph nodes were the most common site of recurrence, and 28% of patients had 11C-choline-positive suspected recurrences outside the initial treatment field. Conclusion: 11C-choline PET/CT can detect PCa recurrence even among patients with low PSA levels when interpretation accounts for the clinical context, providing a certain pre-test probability. Until PSMA agents are fully approved for PCa, choline PET/CT may provide clinical utility.

Participants at the three roundtables, held in Harare and Bulawayo in the first half of 2019, discussed the necessary policies and business strategies to enable and support the effective implementation of the Mnangagwa administration’s Transitional Stabilisation Programme, Vision 2030, and other longer-term national development plans.

This process was conducted by the Chatham House Africa Programme, the Zimbabwe Business Club and the Konrad-Adenauer-Stiftung (KAS); and in partnership with the Confederation of Zimbabwe Industries for a roundtable in Bulawayo. The project was supported by KAS and the Dulverton Trust.

Chatham House US 2020 Election Series

A year-long project focused on what is at stake in the pivotal 2020 US presidential and congressional elections, considering the future of US policy on trade, global economy and technology, national security, transatlantic relations, climate, migration and Latin America.

As part of this initiative, we are launching the Chatham House US Foreign Policy Forum as an incubator for foreign policy dialogue and shared expertise outside of the Washington DC framework.

Meeting regularly, in its inaugural year the Forum will largely focus on the 2020 elections, facilitating discussions around developments in the election and critical policy insights.

These activities support the development of a multi-authored volume outlining the current state of play and potential priorities of a second Trump term, as well as a Democratic administration. The text will contribute to the public debate and research considering the resiliency of US institutions as well as the future of US policy engagement abroad.

Situated in London, this project leverages Chatham House’s world-leading, independent foreign policy institute and unparalleled experience in convening multi-stakeholder discussions to provide a unique, international perspective on the 2020 elections.

COP26 Diplomatic Briefing Series

In the run-up to COP26 in Glasgow, Chatham House is organizing monthly briefings about the UN climate negotiations and climate change more broadly. The events provide an excellent opportunity to discuss the most pressing and complex climate issues of the day with government officials, renowned experts and members of the London-based diplomatic community.

In 2021 the UK is hosting the 26th Session of the Conference of the Parties to the UN Framework Convention on Climate Change, also known as COP26, in partnership with Italy. The meeting constitutes a particularly important COP, given its strong focus on raising climate ambition. It is expected that COP26 will be the largest conference the UK has ever hosted, with up to 200 world leaders attending the final weekend.
 
London is host to one of the world’s largest diplomatic communities, with over 180 embassies and 4000 diplomatic staff. In the run-up to COP26, Chatham House is organizing monthly briefings on key issues related to the COP negotiations and climate change more broadly. The events, which currently take the form of webinars due to COVID-19, are open to members of the London-based diplomatic community and representatives from the UK Government. Reports from the events are published on the event pages below.
