23,000,000,000,000,000,000,000 joules. That’s the amount of heat the oceans absorbed in 2025. A number so huge it’s almost meaningless…until you realise it’s roughly 40× humanity’s annual energy use. The ocean is buying us time. We’re running out of it. www.theguardian.com/environment/...

World’s oceans absorbed record heat equal to 40 times annual global energy use

The injection of thermal energy comes amid an increasing rise in sea levels and continuing acidification

Interesting to compare the 2 sea-ice indices: extent and area. While Arctic sea-ice extent is still approaching its annual minimum, sea-ice area has already passed its minimum. This suggests that initial freeze-up mainly increases ice concentration before expanding the cover. @osi-saf.eumetsat.int

Line plot of Northern Hemisphere sea-ice extent throughout the year for 1978 to 2026, with individual years coloured by decade and 2026 shown in black. Sea-ice extent follows a strong seasonal cycle, decreasing from about 14 to 16 million km² in March to a minimum in September before increasing again. In mid-September 2026, sea-ice extent is still approaching its annual minimum.

Look at the Barents Sea! Relative to the 1981-2010 climate reference period, there is unusually little sea ice for this time of year. In fact, the Barents Sea ice extent has reached record-low levels in six of the past 12 months (Aug-Dec and June), indicating later freeze-up and earlier melt.

Map showing Arctic sea-ice concentration in June 2026 compared with the median June sea-ice edge (1981–2010, orange). The largest departure from the historical average is in the Barents Sea, where the ice edge has retreated far north, indicating unusually low sea-ice extent for this time of year.

Heatmap of monthly Barents Sea ice-extent rankings from 1979 to 2026. Blue indicates months with relatively high ice extent, while red indicates low ice extent. The recent decade is dominated by low rankings, with record-low ice extent occurring in six of the past 12 months (August–December 2025 and June 2026).

Blue colours indicate years with above-average sea ice extent and red colours indicate years with below-average sea ice extent relative to the 1981-2010 climatology average.

Utredning slakter nasjonalt reisekort:

«Etter at billetten er kjøpt, reduseres terskelen for å gjennomføre flere (...) korte, spontane reiser og fritidsreiser som i dag enten ikke gjennomføres eller gjennomføres sjeldnere.»
