Arctic and Baltic sea ice
Arctic sea ice is rapidly declining. On average, the Arctic has lost an area of 73,000km 2 of sea ice per year in summer and 31,000km 2 per year in winter since 1979. ... The Arctic sea ice area for summer 2020 was the second lowest ever and sea ice is becoming younger and thinner. ... An almost ice-free Arctic sea in summer is projected to be a rare event for 1.5°C of global warming but will be the norm for 2.5°C warming. ...

Observed and projected decline in Arctic sea ice area
The left part shows the observed change in Arctic sea ice area (individual observations and trend lines) over the period 1979 to 2024 for March (maximum ice cover) and September (minimum ice cover). ... The right part shows projections of Arctic sea ice area in March and September from CMIP6 simulations for three emissions scenarios. ... The dashed line indicates a threshold for near ice-free conditions. ...

In-situ Sea Ice Data Inventory for Arctic and Antarctic regions
The "In-situ Sea Ice Data Inventory for Arctic and Antarctic Regions" report documents the results of a 2024 survey that gathered metadata on in-situ sea ice datasets across polar regions. ... The survey involved 17 responses from multiple institutions and detailed data on variables such as sea ice thickness, concentration, drift, and snow depth on sea ice. ... Recommendations include enhancing data accessibility, fostering collaborations, and addressing data gaps for improved understanding of polar sea ice dynamics. ...
