The above image shows daily temperature data from end 2022 through April 8, 2025, with two trends added, a black linear trend and a red cubic (non-linear) trend that reflects stronger feedbacks and that follows ENSO (El Niño/La Niña) conditions more closely.

The shading added in the above image reflects the presence of El Niño conditions (pink shading) that push up temperatures, La Niña conditions (blue shading) that suppress temperatures, or neutral conditions (gray shading). 

Such short-term variables are smoothed out in the black linear trend that shows a steady rise of 0.5°C over 3½ years (from 2023 to half 2026), a much steeper rise than the 1.1°C rise over 81 years (from 1941 to 2022) of a linear trend in an earlier image.

A new El Niño may emerge soon and the red trend warns that the temperature could rise strongly in the course of 2026, due to feedbacks and further mechanisms such as a El Niño and loss of sea ice.

High ocean temperatures result in low Arctic sea ice volume, as illustrated by the image on the right and as discussed in this earlier post.
As the likeliness of a huge and accelerating temperature rise, the severity of its impact, and the ubiquity and the imminence with which it will strike all become more manifest—the more sobering it is to realize that a mere 3°C rise may suffice to cause human extinction.

DJ, This is very depressing....https://forum.arctic-sea-ice.net/index.php/topic,4329.300.html#bot or https://forum.arctic-sea-ice.net/index.php/topic,4329.300.html#bot ; NSIDC ARCTIC SEA ICE AREA (5-day trailing average):  12,384,989 KM2 as at 09-Apr-2025

Although there was a 10k sea ice area loss on this day hopefully signifying the end of the freezing season (at a ridiculously late date), this is entirely down to losses in the peripheral Seas. Sea ice area in the High Arctic continues to increase.

And the sea ice area losses in the Peripheral Seas are mostly down to losses in the Okhotsk and St Lawrence Regions which are somewhat separate.

Projections. (Table NSIDC Antarctic-Area-1)
Average remaining freeze (of the last 10 years) would produce a maximum in Sept 2025 of 14.09 million km2, 0.71 million km2 above the 2023 record low maximum of 13.37 million km2, and would be 3rd lowest in the 47 year satellite record

DJ, Increase heat=increase of weather extremes...
