4/ Emissions cuts? Temperature limits? 🧊 As @iccinet.bsky.social says, we cannot negotiate with the melting point of ice.

“Losing sea ice is making climate change up to 15 percent worse than it would otherwise be.” — @edoddridge.bsky.social @utas.edu.au

BY 2030: "The remaining carbon budget to limit global warming to 1.5°C is virtually exhausted and is equivalent to only four years of current emissions." — @pfriedling.bsky.social and @hausfath.bsky.social on the 2025 Global Carbon Budget in @carbonbrief.org

3/ This year-long visualisation of PACE chlorophyll data shows areas with high chlorophyll concentration in red and yellow, medium chlorophyll in green and low chlorophyll in blue and purple. This covers one year, revealing the seasonal cycle of phytoplankton activity.

1/ More than 600km above 🌏, NASA's PACE (standing for Plankton, Aerosol, Cloud, Ecosystem) satellite is in a polar orbit. Covering the globe in about two days, it gathers data on ocean colour, aerosols, and clouds enabling the study of climate change and ocean ecosystems.

🌊⚠️ "Understanding and predicting marine-terminating glacier instability presents one of the greatest challenges to forecasting future sea level rise" — case of the Hektoria Glacier in #Antarctica, which retreated ~25 km from Jan 2022 to March 2023.

🌊 We work to turn our research @utas.edu.au into real-world impact, to inform decision-making that recognises the centrality of #Antarctica and the Southern Ocean to the global climate system.

🌀The stratospheric polar vortex is a belt of high-speed cyclonic winds around 12-20km high over the poles. When temperatures in the stratosphere – which contains the ozone layer – start rising in the southern spring, the ozone hole over the Antarctic grows.
