Speaker(s):
Notes & Changes
For this event only, I draw your attention to two matters:
First, the first seminar, and for this seminar only for this term, will take place in the Wharton Room, instead of the Old Library. A sandwich lunch will be provided in the Hovenden Room, instead of the Wharton Room from 12.15 pm and onwards.
Second, I’m sorry to inform you that the venue has a limited capacity, accommodating approximately 40 people. May I kindly ask that you first register if you plan to participate in person, and only register if you’re certain of attending. I’ll send an email earlier that week (i.e. the week of the seminar) to confirm whether you’d be able to participate in the event in person.
Please contact me if you need to cancel your registration, only if you registered to attend in person, so that I can offer the place to others who have expressed interest in attending the event. Please let me know if you require an earlier confirmation to schedule your trip in advance, if you’re attending outside of Oxford. Participation will be determined on a first-come, first-served basis when registration opens on Monday, 6 October 2025, at 9.00 a.m. British Standard Time.
If you specify that you will join online, you will be sent a Teams link before the event. I’ll aim to send the online link once the form closes on Wednesday (i.e., 15 October) at midday. A separate email will be circulated to confirm your participation in person. Email access will be limited on the day of the event, as well as after the form closes. I kindly request that you communicate and register in advance.
On 23 July 2025, the International Court of Justice delivered a landmark advisory opinion on the Obligations of States in respect of climate change. This lecture explores the strategy, process, outcome and potential impact of the advisory opinion seen ‘from the cockpit’. It discusses the many close calls, scientific challenges, political hurdles, coordination and positioning issues that had to be overcome as well as the deep fault-lines underpinning the request, the pleadings and the opinion.
