US to retire its only icebreaker, stranding polar research - new article posted today by @cuboulder. The icebreaker is critical for researchers who study the changes on the edges of Antarctic glaciers and how they relate to climate change and sea level rise. buff.ly/oMAElHY #antarctica #glaciers

The five geoengineering concepts being considered to mitigate the effects of global warming in polar regions are unlikely to work, researchers reported in a new study published in Frontiers in Science.

Our paper is out, providing alternative viewpoints to some polar geoengineering ideas covered in the media recently. Lots still to talk about but let's focus on decarbonising instead of drilling Antarctica for now? 🇦🇶 Thanks @newscientist.com @mjflepage.bsky.social for covering this important issue!

First day as a Professor! 🤩🫣🤯

Met Office stats confirm summer 2025 is officially the warmest summer on record for the UK. The UK’s mean temp of 16.10°C surpasses the previous record of  15.76°C and pushes the summer of 1976 out of the top 5 warmest summers. www.metoffice.gov.uk/about-us/new...

"The simple fact is that carbon dioxide is making the oceans more acidic, which carries harmful effects," said CIRES Director Waleed Abdalati in this AP story: Scientists give harsh grades to Trump administration work aimed at undoing a key climate finding.

“It can really create perceptions of false equivalence in the public sphere,” said Max Boykoff, an environmental studies professor at the University of Colorado Boulder. Grist story: Why the US government is trying to revive the climate change ‘debate.'

"I think the most rewarding moments are those aha moments when students really get it and they kind of leap to the next level." Jen Kay, a professor in Atmosphere and Oceanic Sciences (ATOC) at @colrado.edu is our most recent "Voices of CIRES." buff.ly/iYXctxT #atmosphere #forecasts #Arctic

Antarctica’s McMurdo Dry Valleys are one of the most extreme places on Earth 🌍❄️. I talked with @drgilbz.bsky.social about my PhD research on the glaciers there, why they matter for climate and ecosystems, and how they’re changing in a warming world. Check the great video she made below ⬇️

Interesting perspective on higher ed teaching in the age of AI (gift link): www.nytimes.com/2025/08/26/o...

Provisional statistics from the Met Office show that summer 2025 will ‘almost certainly’ be the warmest summer on record for the UK. It would move 2018 off the top spot and relegate 1976 out of the top five warmest summer in a series which dates back to 1884. 👉 www.metoffice.gov.uk/about-us/new...

Thanks everyone, it’s been fun being a scientist in the US. 👋

Excited to share that some of the results from my master’s research have been published! Using SAR, we found evidence of winter meltwater persistence on George VI Ice Shelf and upstream of its grounding line 🛰️🧊 www.frontiersin.org/journals/ear...

I’m delighted to share that our new paper is now out in @natclimate.nature.com! Our long-term, monthly Antarctic-wide dataset of surface meltwater shows that the East Antarctic Ice Sheet is becoming increasingly prone to surface meltwater ponding.

Regardless of where we live or how we vote, extreme weather puts us all at risk: and we know, without a shadow of a doubt, climate change is making it worse. To build resilience, we need more data, more expertise, more preparation, more communication to keep people safe—NOT LESS! More from me:

A Met Office study reveals that the chance of exceeding 40°C in the UK is accelerating at pace. The chance of exceeding 40°C is now over 20 times more likely than it was in the 1960s. Temperatures several degrees higher than we saw in July 2022 are possible in today’s climate. bit.ly/4lfcTU4
