Jeg tror dette er godt kjent blant alle som jobber med planlegging i Norge: Vi er verst i Europa på å bygge ned natur.

Incredible ice loss measured again at #Konkordiaplatz on the #Aletsch #Glacier, home to the thickest ice in the #Alps (still about 800 m!). Yesterday’s survey revealed another –4.6 m of ice gone in just one year. :( Measurements by @matthias-huss.bsky.social for GLAMOS

Witnessing the rapid and extensive thawing of permafrost in Svalbard is truly impressive but deeply concerning

"Melting on the Arctic’s Svalbard Islands Shows the Climate Future Is Now" by @bberwyn.bsky.social for @insideclimatenews.org: insideclimatenews.org/news/1908202...

Ice melt records set in 2020 and 2022 were just marginally greater than previous years, but an extreme and long Arctic heat wave last summer, intensified by weather patterns disrupted by climate change, opened a new page in the record books insideclimatenews.org/news/1908202...

During the summer of 2024, six weeks of record-smashing heat led to a record-obliterating amount of ice melting on the islands of Svalbard in the Arctic.

Summer 2024 featured unprecedented warmth in the European Arctic, causing melting of 1 % of the total ice volume on Svalbard. Bad news is that in 2100 and even in the optimistic SSP1-2.6 emission scenario, 50% of the future summers will be warmer than 2024. www.pnas.org/doi/10.1073/...

Shocking stats from this paper on the extreme 2024 summer heat in Arctic Svalbard, which lost 1% of its total ice volume in just ~6 weeks. 🔥 In fact, Svalbard's 2024 glacier mass loss actually exceeded that of the Greenland Ice Sheet, which is 50 times larger!!! 😱 www.pnas.org/doi/10.1073/... ❄️🧪🌊

2024 glacier loss in Svalbard was beyond imagination! 😱 - Anomaly of up to 4 SD! - Amounts to ~61.7 Gt => 1% of the total ice volume - Comparable to that of the Greenland ice sheet (55 Gt), which is 50 x larger! ... Otherworldly! 🪐 www.pnas.org/doi/10.1073/...

Our latest research investigates the remarkable heatwave that affected part of the Arctic in the summer of 2024. It caused a 1 percent loss in Svalbard's ice, making this region one of the most significant contributors to global sea-level rise last year www.pnas.org/doi/10.1073/...

This July reminded us that in the north, heat is not a distant threat but is seeping into hospitals, care facilities & homes. Our infrastructure was not built to withstand these extreme temperatures and our population is increasingly susceptible to dangerous heat www.theguardian.com/environment/...

Getting used to this image: #glaciers almost completely naked - unprotected by the white snow - in August... While July was good for glaciers after record-melt in June, the new heat wave again results in major ice loss @vaw-glaciology.bsky.social

This is unbelievable. The high temperature at one of Finland’s northernmost weather stations, in the municipality of Sodankylä (Lapland region) within the Arctic Circle at latitude 67.3°N, reached at least 25°C for 26 days in a row. Records date back to 1908.

Inspired by @ketilisaksen.bsky.social post, I did the same analysis for Finland. In terms of 14-day average temperatures, the 2025 heatwave in Finland did not quite surpass the well-known 1972 and 2018 heatwaves. This is based on 10 km gridded observations.

Melting glaciers threaten to wipe out European villages - is the steep cost to protect them worth it? www.bbc.com/news/article...

En sommer med ekstremvær www.nrk.no/klima/ekstre...

Disregarding the extreme and record-low sea-ice extent in Antarctic the last two years, this year's July extent is exceptionally low, ranking as the 3rd lowest on record. The July extent over the last four years differs significantly from that of the previous four decades. @osi-saf.eumetsat.int

Nordic countries hit by ‘truly unprecedented’ heatwave www.theguardian.com/environment/...

20 straight days with 30 °C in Finland! Truly unprecedented heatwave still in full swing with maximum today about 32-33 degrees. Even the Arctic regions (e.g. Sodankylä Tähtelä) have seen three weeks above 25 °C, and may rival tomorrow their August heat records.

The heatwave in Finland could last another week or so as the Omega pattern strengthens over northeast Europe. The persistence of the heatwave will make it definitely one of the strongest on record in Finland, if not the strongest.

Melting over 80.6% of the area of the Greenland Ice Sheet. This is the highest value in our data set, which starts in 1981. @polarportal.bsky.social

We must wait for detailed attribution to determine exactly how much climate change accelerated the timeline of this collapse. However, the balance of the evidence (given the impact of warming on ice and permafrost) suggests a number is greater than zero, and this was a climate-enhanced event. //

The #Arctic is getting wetter during the month of May across many regions of the Arctic Ocean. The largest trends are closer to areas of greater sea-ice loss toward the Atlantic Ocean. + Data: psl.noaa.gov/data/gridded... + Info: doi.org/10.25923/xf7...

The deep permafrost in Svalbard is warming at an accelerating pace

En mild vinter i høyfjellet i Sør-Norge har påvirket permafrosten🌡️ –Temperaturen i de øvre delene av permafrosten er nå normalt på sitt kaldeste, men er høyere enn noen gang registrert for denne årstiden på Juvvasshøe, og har vært det i nesten hele 2025, sier klimaforsker @ketilisaksen.bsky.social

Mapping changes in temperature: every decade from the 1850s to 2020s

Preliminary data suggests that the global average increase in atmospheric CO2 concentration in 2024 will be a record. Not just a little record, but 25% higher than the previous record. (This is the global average, as opposed to Moana Loa) gml.noaa.gov/ccgg/trends/... 1/

🔴The #StateOfClimate report, released today, reveals key climate change indicators again reached record levels in 2024. Check out the full report: wmo.int/publication-...

Pleased to announce that we now have two permafrost monitoring sites in Svalbard - Kvadehuken and Bayelva -officially accepted within the WMO CryoNetCluster oscar.wmo.int/surface/#/se...

Arctic 50-year average temperature change for winter, updated to include 2024-25. Warming in excess of 11ºC (!) in the Barents Sea and Svalbard areas due to mid-winter sea ice loss. No warming since the mid-1970s in eastern Siberia and parts of Greenland. Data from ERA5. #Arctic #ClimateChange

Winter 2024-25 was the mildest on record for the Arctic overall. About 95% of lands and seas north of 60ºN latitude had an average temperature above the 1991-2020 baseline. Only parts of the Greenland were even a little bit colder than normal. ERA5 data courtesy of ECMWF/Copernicus. #Arctic #Climate

The opening of melt pools and glacier-fed streams and rivers is typical of late spring, perhaps May - but here we are in Svalbard in winter (February) with positive degrees and there is water everywhere 🌡️😰
