🧊 Arctic sea ice slowdown?

Ice hasn’t shrunk much since 2005 β€” but it’s still half the 1980s size. This pause is natural variation, not recovery. The Arctic is warming 4x faster than the global avg.

πŸ“‰ Loss could soon accelerate fast.

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between May and August by looking at the decadal average line positions.

A female Western Gull was recorded riding 150km in a garbage truck from San Francisco to a compost facility in Central CA, probably to forage. TWICE. An innovator, an icon, a genius.

🌊 Happy #WorldOceansDay from SCAR!

Today, we celebrate the mighty Southern Oceanβ€”a climate hero that deserves the spotlight.

To mark the day, we’re sharing three stunning data visualisations from a past EG-ABI competition, showcasing the impacts of climate change on the Southern Ocean.

Why Spring Is Critical for Harp Seal Pups ❄️

Harp seal pups are weaned just 10-12 days after birth. By spring, they must adapt fast as sea ice melts. As the Arctic warms, ice breaks up earlier, threatening pup survival and disrupting the marine food web.

For decades, this iconic graph has provided clear observational evidence of one of the key indicators of global climate change - Arctic sea ice loss. It’s from the NSIDC "Sea Ice Index"

Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basicβ€”meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

This time of year trends in sea ice concentration are confined to the very outer edges of the #Arctic Ocean. Losses of concentration are smallest in March and April (around the annual maximum).
