Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what plans they have to discuss with international partners the warnings by scientists working in the International Thwaites Glacier Collaboration of the potential for ice shelf failure along the Thwaites Glacier in the next decade.

The UK is always seeking to discuss issues with our international partners where appropriate opportunities arise. This is no exception and there is a strong international community involved in monitoring and discussing the risk around the Thwaites Glacier.

In 2018, the UK Natural Environment Research Council (NERC) and the U.S. National Science Foundation (NSF) funded the International Thwaites Glacier Collaboration, a five-year £20million Antarctic research programme and the largest joint project undertaken by the two nations in Antarctica for more than 70 years. This project is aimed at collecting instrument data throughout the glacier and the adjacent ocean, and modelling ice flow and the future of the ice sheet. The collaboration involves around 100 scientists from world-leading research institutes in both the US and UK alongside researchers from South Korea, Germany, Sweden, New Zealand and Finland, who will contribute to the various projects.

The changes that may occur in the vicinity of the grounding line of the Thwaites Glacier in the next decade will not, of themselves, result in a significant change in global sea level. While some computer models predict that such changes may lead to a wider loss of ice to the ocean, these are processes occurring on century timescales. For this reason, the NERC and BAS priority at present is to continue to monitor the Thwaites Glacier with satellite and ground observations, as they are presently undertaking in collaboration with the US.
