June 2025 #Arctic sea ice extent was the 2nd lowest on record for the month...

This was 1,280,000 km² below the 1981-2010 average. June ice extent is decreasing at about 3.68% per decade. Data: NSIDC (https://nsidc.org/data/seaice_index).

Animation of a blue moving line graph time series of Arctic sea ice extent for every June from 1979 to 2025. A red dashed line is also annotated to compare 2025's levels. There is a long-term decreasing trend and large interannual variability.

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.
