Antarctica’s melt affects everybody but won’t hit every coastline the same. New maps show where seas could rise the fastest, and why millions of coastal residents should pay attention now 🌊
Sea level doesn’t rise at the same rate everywhere – we mapped where Antarctica’s ice melt would have the biggest impact
Understanding what happens to Antarctica’s ice matters, because as it melts, sea levels rise, affecting lives and economies around the world.

Global mean sea surface temperature anomalies (departure from average) so far this year ➡️ 2nd highest on record 🌊 Data from NOAA ERSSTv5 averaged over January to September.
🌊 Ocean warming threatens the viability of 60% of Antarctic ice shelves If global temps stay <2 °C, nearly all 64 ice shelves survive by 2300. But above ~4.5 °C, ocean melt causes 38 shelves to collapse by 2300, risking up to 10 m sea level rise. www.nature.com/articles/s41...
Ocean warming threatens the viability of 60% of Antarctic ice shelves - Nature
The viability of Antarctic ice shelves under low rates and high rates of global warming is modelled to estimate when it will become unfeasible for the ice shelves to maintain their present-day shape.
nature.com
Up to 59% of Antarctic ice shelves may be at risk of disappearing under high-emission scenarios by 2300, according to an analysis of the effect of ocean warming in Nature. This could result in up to 10 m of global sea-level rise. go.nature.com/47Ag4k1 🌊 🧪

The way light reflects and refracts from water, esp. near the coast, has a lot to do with the sediment ( and other) particles suspended in them. What I didn't realize was that the waves can orient the particles, and thus how light behaves. 🧪🌊 Link: aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

🌊 Melting Arctic ice is opening the Arctic Sea Route, reshaping global trade, but at a cost. A new study finds ASR use could raise global shipping emissions by 8.2% by 2100. Current policies fall short…only a net-zero strategy can curb Arctic impacts. www.nature.com/articles/s41...
Arctic Sea Route access reshapes global shipping carbon emissions - Nature Communications
Arctic Sea Route access will raise global shipping CO2 by 8.2% by 2100 and worsen regional inequities. IMO 2023 strategy and Green Corridor plans fall short; only a net-zero pathway with stricter fuels and phased rollout eliminates ASR emissions.
