Cover page of UK Government document titled "Global biodiversity loss, ecosystem collapse and national security: A national security assessment." Features the HM Government crest and an abstract design of overlapping coloured circles in pink, orange, green, blue and muted tones. Marked "UK OFFICIAL".

The UK Government just released its national security assessment on #biodiversity loss: an actual intelligence assessment using the same frameworks as military threat analysis. The conclusion? #Nature is a foundation of national security and every critical #ecosystem is on a pathway to collapse. 🧵

The show also does a great job of highlighting the importance of coproduction of knowledge and engagement with impacted Inuit communities, including when Max Kotokak Sr and Kevin Arey came to the UK to present the Imaryuk Monitoring Programme and its links with the BARIN beaver project.

Huge paper for the Arctic Ocean published today in @science.org - a new 30,000 year history of Arctic Ocean sea-ice cover reconstructed from the accumulation of cosmic dust-derived helium-3! www.science.org/doi/10.1126/... (1/n)

That's great, thank you! I should have a paper coming out soon on my part of the work too 🤞🏼🤞🏼

The Story of Earth's Climate in 25 Discoveries: How Scientists Found the Connections Between Climate and Life - GEOSCIENTIST Donald Prothero takes readers on a sweeping 4.5-billion-year journey that reveals the intimate ties between climate and life.

My review of ‘The Story of Earth’s Climate in 25 Discoveries’ by Donald Prothero has been published in The Geological Society's Geoscientist magazine. The book is a sweeping exploration of Earth’s 4.5Ga climatic journey and its role in shaping life.

Always fun to join another UK Arctic Science Conference, this time at @northumbriauni.bsky.social, presenting initial stages of palaeo sea ice reconstruction, synthesis and mapping, within the @horizoneu.bsky.social project Past2Future - towards fully palaeo-informed climate projections.

Look forward to reading this!

Thank you all for attending BOGS 2025! We are a great community, and we look forward to many future successful meetings.

Thank you so much! 🙏🏼

I spent the last two summers sampling alder and willow shrubs in the tundra, so I do miss those landscapes!

Last week I was at @noc.ac.uk for the first time since 2012(!) for a workshop on the contribution of Arctic Ocean science to the International Polar Year 2032/33. A great opportunity to help shape priorities for future research with a cross-section of polar ocean experts.

Thank you!

Very cool 🤩

Kick off meeting in Utrecht for the Past to Future project - towards fully palaeo-informed future climate protections.

A great kick off in Utrecht to my role within the new #HorizonEU #Past2Future project, working towards fully palaeo-informed future climate projections.
I'm joining @durham-university.bsky.social as a research associate, focusing on Arctic and Antarctic sea ice reconstruction.

World's sea-ice falls to record low The world's frozen oceans keep the planet cool, but they currently have less ice than ever recorded before.

Sea ice in the Arctic and around Antarctica cool our climate, drive ocean circulation across the planet, and provide a unique habitat for polar ecosystems.

Sea ice amounts have now fallen to their lowest since we started measuring them. This is not good.

Ancient Tree Rings Hold Clues to Volcanic Cooling Events In the frigid reaches of northern Norway, a curious phenomenon in tree rings is helping scientists uncover the climatic impact of distant volcanic eruptions from over a century ago. Researchers have discovered that unusually cold summers leave behind distinctive blue-tinted rings in trees and shrubs, providing a natural archive of historical temperature drops. The study, published in Frontiers in Plant Science…
