❄️The High-level International Conference on Glaciers' Preservation is happening in one week in Dushanbe, Tajikistan, May 29-31. dushanbeicgp2025.com Building momentum during #IYGP2025, speakers will highlight how mitigation is key to preserving global snowpack and glaciers. Program linked above.

Key findings: www.nature.com/articles/s43... Current climate forcing (1.2 °C) if sustained is likely to generate several meters of sea-level rise over coming centuries, causing extensive loss and damage and challenging adaptation measures. Avoiding this requires returning closer to or below 1 °C.

Coastlines in danger from irreversible ice sheet melt even if 1.5C climate target is met, scientists warn www.bbc.com/news/article...

Scientists show that +1.5 °C is far too warm for Earth's ice sheets and will result in several metres of sea-level rise over the coming centuries, extensive loss and damage to coastal populations and will challenge the implementation of adaptation measures www.nature.com/articles/s43...

Hot off the press! The State of the Cryosphere 2024 report has been officially translated into Chinese Read the full translation: iccinet.org/statecryo24 We aim to translate this report into more languages; if interested in supporting these efforts, we welcome you to reach out.

Last month observed temperature anomalies more than 5°C above the 1981-2010 average across parts of Siberia. Elsewhere, most areas were also anomalously warm, except around the Fram Strait/Greenland Sea and Hudson Bay. High resolution version updated monthly at zacklabe.com/arctic-tempe....

Carbon dioxide (CO₂) averaged nearly 430 ppm in April 2025 (new record high) 10 years ago April averaged about 404 ppm. Preliminary data from gml.noaa.gov/ccgg/trends/... This isn't going away. The longer we wait to address climate change, the greater the impacts and the harder it becomes to solve

Icebergs? The size of a city? 90 miles from the UK? Must be a joke, right? No! Our new paper in @natcomms.nature.com shows massive tabular icebergs broke off the UK in the last ice age before the UK’s ice shelves disintegrated from climate warming. 🧵 www.nature.com/articles/s41... @bas.ac.uk

'Goodby Glaciers' Glacier Blanc (Ecrins massif) Volume ~0.3 km³ (2020) Will be mostly gone by 2061 under 2.7°C global warming With 1.5°C, 13% of the 2020 volume is expected to remain (10% more compared to 2.7°C). Check the 'Goodbye glacier' project website goodbye-glaciers.info/glaciers/RGI...

This is almost unbelievable. It's now May and there is still virtually no new sea ice forming in the Bellingshausen Sea (lower left region in image). Image showing sea ice concentration derived from AMSR satellite data is by Institute of Environmental Physics, University of Bremen, Germany.

🧵🧪🏆🥇We've done it! We've raised atmospheric CO₂ concentrations to the point where, for the first time in human history, they have exceeded 430 ppm every day for a full week. It had become fairly certain that we'd reach this landmark sometime this month, but even so it's a fairly sobering moment.

Today, as we celebrate our planet, one vital component in Earth's climate system stands out: the cryosphere. Snow and ice loss can impact every region on Earth. It influences sea levels, water resources, food security, weather and ecosystems. 1.5°C is an essential guardrail in 2025 & beyond ❄️

Annual average CO2 levels made a record-breaking jump in 2024, increasing by 3.75 parts per million (ppm) compared to the previous year. That is 25% larger than the previous record jump of 2.96 ppm set in 2015. Read more: gml.noaa.gov/ccgg/trends/...

"Glaciers may be shrinking due to scorching temperatures, but we cannot shrink from our responsibilities" says UNSG António Guterres. "Every country must deliver strong national Climate Action plans this year, aligned with limiting global temperature rise to 1.5C." www.linkedin.com/feed/update/...

“Glacier preservation is more than an environmental need: it is a moral obligation. It is about about justice, resilience, and survival, said H.E. Mr. Sirojiddin Muhriddin, Minister of Foreign Affairs, Republic of Tajikistan.

Happy World Glacier Day!! As we enter into the International Year of #Glacier Preservation, we must: - redouble efforts to scale up political ambition for widespread emissions reductions - fight to prevent every tenth of a degree of warming - Ensure countries submit 1.5C aligned NDCs at COP30

🔵 The UN #WorldWaterReport 2025, published by UNESCO on behalf of UN Water, reveals the extent to which climate disruption, biodiversity loss, and unsustainable activities are transforming mountain environments at an unprecedented rate. Read more: unes.co/re39dj #WorldGlaciersDay #WorldWaterDay

ICCI are at @unesco.org in #Paris today discussing how to secure a strong policy legacy of the Decade of Action for Cryospheric Sciences ❄️ Underscoring the urgency of #decarbonization and emissions reductions must be a strong message carried through the Decade: Action must start now!

⏰ Atmospheric CO2 levels have now exceeded 430 ppm for the first time since records began, marking a grim milestone for the future of the Earth's polar regions Full press release: iccinet.org/media-center/

Greenland’s rapidly melting ice will make the oil and minerals Trump covets dangerous to extract and expensive. From @paul-bierman.bsky.social theconversation.com/greenlands-r...

I argue here we need to follow the science not the whims of politicians. Greenland's value is its ice. Free to republish. Pass it on. Spread the word. We need to bring science and rational thought back into the national dialogue . @us.theconversation.com 💙📚🧪 theconversation.com/greenlands-r...

Glaciers worldwide lost 273 ± 16 BILLION tonnes of ice annually from 2000 to 2023! Losses increased by 36% between 2000–2011 to 2012–2023 Sobering results from GlaMBIE Team, which underline the need for greater climate ambition in this year of #glacier preservation www.nature.com/articles/s41...

Cutting GHG emissions - in line with the 1.5C Paris Agreement target - is the only means to preserve glaciers worldwide. Greater political ambition to mitigate climate change must therefore remain the No.1 focus to prevent the widespread loss of glaciers and their critical role in human wellbeing.

It is both the case that the 2% of the planet that is it United States is remarkably frigid at the moment, and that the world as a whole is at record-warm levels for this day of the year:

The International Year of Glaciers' Preservation is so important because losing glaciers to global warming would have severe negative consequences that include damage to the power and agricultural industries, increased transboundary water conflict and greater downstream hazards #Glaciers2025

The Year of Glaciers' Preservation coincides with the deadline for the next round of climate commitments under the Paris Agreement. Scaling up political ambition to stay within the 1.5C Paris limit is essential for preserving glaciers and the huge benefits they bring for society #Glaciers2025

Today is the launch of the International Year of Glaciers' Preservation! Join online from 2 pm CET to hear about the objectives of the year and why it is so essential to preserve glaciers globally. wmo.int/events/meeti...
