Under the banner of ‘Friends of Science’, in an overflowing press conference at SB64, diplomats from Fiji, Nepal, the EU, Switzerland, Sierra Leone and Panama vowed to ensure that decision-making in the UN climate process remains based on the “best available science”. @climatechangenews.com 🔗 ⬇️

Yesterday, ICCI had the privilege of co-moderating two sessions at the Dialogue on Mountains and Climate Change at #SB64. Mountains are of global importance. Their glaciers and snowpack regulate river flow, support agriculture and livelihoods, and store freshwater that billions of people depend on.

57 countries gathered in Santa Marta for the first-ever conference dedicated to transitioning away from fossil fuels, and here are three key takeaways from the closing plenary 🧵

For the first time, countries, communities, and civil society convened outside formal UN climate talks with a single focus – the practical delivery of the fossil fuel transition. After six day of meetings, the closing plenary in Santa Marta is now underway! transitionawayconference.com

Today, scientists and researchers released the Santa Marta Action Repertoire (SMART), the culmination of over five months of work. It presents 12 core insights from 16 work streams that will be shared with governments at the High-Level Segment (Tue-Wed), followed by a synthesis report. Link below!

The first international conference dedicated to transitioning away from fossil fuels began last Friday, co-hosted by Colombia 🇨🇴 and the Netherlands 🇳🇱 Our Global Mountains Director is on the ground all week, advancing discussions on a just, science-based transition. transitionawayconference.com

Happy #EarthDay! 🌍 Today we are launching a white paper on Barriers to Glaciers-Related Financing. As temperatures continue to rise, finance will be needed to respond to the impact of glacier loss on mountain 🗻 and water 🧊 ecosystems. iccinet.org/glacier-fina...

2026 Arctic sea ice maximum ties with record-breaking low set in 2025. This year’s maximum sea ice extent likely occurred on March 15, reaching only 14.29 million km2. This is the smallest maximum in the 48-year satellite record, falling about 20,000 km2 lower than 2025. @nsidc.bsky.social

The World Meteorological Organization report on the State of the Global Climate 2025 was released today: "Earth's energy imbalance has been growing since the 1960s, reaching a record high in 2025." "Extreme weather impacts millions and costs billions." Press release: wmo.int/news/media-c...

Today is the opening day of the 2026 Monaco Polar Symposium from Feb 25-27. The key focus: actionable steps to translate polar research into climate action 🧊 We will share more about the program, panels, and key moments throughout the week! #Cryosphere #ClimateAction

The future of the Antarctic Peninsula under three different scenarios - the choices we make today determine the future. Policy Brief with @granthamicl.bsky.social spiral.imperial.ac.uk/entities/pub...

Future of the Antarctic Peninsula depends on choices today! High emissions cause more days above 0C, rain, ocean warming, and more extreme weather events. Limiting temps below 2C, with effective governance to increase resilience will limit potential change. www.frontiersin.org/journals/env...

Tipping points of the #Antarctic ice sheet revealed! Temperatures of 1–2 °C above preindustrial levels triggers the long-term collapse of 40% of marine ice in West Antarctica once the ice sheet fully responds. Marine-based sectors in East Antarctica are at risk of losing stability at 2–5 °C.

NEW: Antarctic ice sheet not one tipping element, but interacting basins with distinct thresholds. ~40% of West Antarctic ice may be committed to long-term loss; parts of East Antarctica face risks at 2–3°C. @ricarda-winkelmann.bsky.social @juliusgarbe.github.io www.pik-potsdam.de/en/news/late...

How can cryosphere science shape climate policy? AMI Chief Science Advisor Dr. James Kirkham explains how cryosphere science can inform UN climate negotiations, build political ambition, and help protect melting snow and ice at a critical moment for climate action. www.youtube.com/watch?v=oyfD...

ICCI's @jdkirkham.bsky.social will be speaking next week on cryosphere science diplomacy, what happened at #COP30, and what to look out for in 2026!

Rising temperatures could to lead to the loss of thousands of glaciers per year, with up to ~4,000 vanishing annually under high emissions. 1.5°C could halve this loss 🧵 @landervt.bsky.social @harryzeko.bsky.social @matthias-huss.bsky.social @davidrounce.bsky.social @lilianschuster.bsky.social

Join us at UNEA-7 this Thursday Dec. 11 on International Mountain Day: Moderated by @unep.org's Mr. Lewis Pugh, the event will focus on cryosphere changes, regional solutions for mountain ecosystems, and frameworks for assessing losses of biodiversity and ecosystem services. 🔗 Livestream below!

Reflections on COP30 Global Mutirão final decision text:

Welcome to Day 3 of #COP30! Today’s focus: Polar Oceans 🌊❄️ Policy experts, scientists & Indigenous voices highlighted how safeguarding the cryosphere is vital to keeping 1.5°C within reach and ensuring a stable climate for all. #Cryosphere #ClimateAction #Arctic #Glaciers #OceanProtection

This morning’s session at the #COP30 Cryosphere Pavilion discussed the impacts of black carbon in the Arctic. Updated emissions data and improved atmospheric modeling highlight why rapid reductions in black carbon remain essential for effective Arctic and global climate policy. Full schedule below!

Proposals to artificially cool the world’s polar regions to stem the impact of global warming are expensive, unfeasible and potentially dangerous, scientists say.

An authoritative group of #climate scientists have reviewed 5 prominent ideas to #geoengineer the polar regions. They conclude that these ideas are economically and practically unfeasible, environmentally dangerous & have major governance & ethics issues. www.frontiersin.org/journals/sci... 🌊🧪

#ShowYourStripes Day! SCAR INSTANT is attending the ATCM in Milan, italy 🇮🇹. Temperature in Milan have increased drastically over the past 10 years. as the first heat wave strikes, it reminds us that polar areas are vunerable but regulate the temperature of the planet.🌏 @scar-antarctic.bsky.social

Today is the first day of the 47th Antarctic Treaty Consultative Meeting, held in Milan 🇮🇹 from June 23-July 3. It will take place alongside the 27th meeting of the #CEP. An important issue: the risk of multi-meter sea level rise if critical thresholds in the Antarctic Ice Sheet system are crossed.
