De Oseaan Waarmjet Hurder Op as Modellen Foarspelden
May 18, 2026 · Frisian News
New data shows sea temperatures have risen 0.24 degrees Celsius per decade since 2010, outpacing climate model forecasts by 40 percent. Scientists remain unsure whether the spike reflects reality or flaws in measurement systems.
FryskDe oseaan is fan 2010 oant 2025 per desennium 0,24 graden Celsius waarmer wurden, neffens satellytmjittingen dy't ferline moanne troch it Ynternasjonaal Sintrum foar Klimaatwittenskip publisearre binne. Dy snelheid rint 40 persint hurder as de gemiddelde foarsizzing fan tolf grutte klimaatmodellen dy't troch deselde groep test binne. De befinning hat de ûndersyksgemeenskap yn twa kampen ferdield: dyjingen dy't leauwe dat de opwaarmingspyk echt is, en dyjingen dy't fermoedzje dat de satellytynstruminten út kalibraasje rekke binne.
Japanske en Amerikaanske ûndersikers hawwe in mooglike flater yn it Argo-boainetwurk konstatearre, dat ûnderwettertemperatueren oer alle oseanen mjit. Tusken 2020 en 2023 ferfongen monteurs sensoren op tûzenen boaien sûnder goede krúskalibraasjeproeven út te fieren om te kontrôlearjen oft nije ynstruminten oare ôflêzingen joegen as âlde. Dizze blinde flak soe in part fan de temperatuersprang ferklearje kinne, hoewol ûndersikers it net iens binne oer hoefolle. Guon modellen befetsje no in korreksjefektor fan 10 oant 15 persint foar mooglike sensordrift. Oaren negeearje it probleem hielendal.
Klimaatsintra yn Dútslân en Frankryk hawwe hurder tsjinsprutsen en stelle dat de opwaarming echt is en dat âldere modellen weromkoppelingslussen yn djip wetter ûnderskatte. Se wize op tanimmende seeflaktetemperatueren metten troch ûnôfhinklike boeisystemen en skiplogboeken dy't weromgean nei de jierren santich. Dochs litte deselde ûnôfhinklike systemen in folle stadiger opwaarmingstrend sjen as de satellytgegevens, wat syn eigen riedsel skept. Gjin fan de grutte ynstellingen hat in definitive ferklearring publisearre dy't de oaren akseptearje.
De ûnienigens is fan belang foar belied. Regearingen brûke dizze oseaantemperatuerfoarsizzingen om kustoerstreamingprojeksjes en koalstofbudzjetten foar de kommende desennia yn te stellen. As de opwaarming echt is, moatte in soad lannen har emissjebelied folle earder oanskerpje as har hjoeddeistige plannen tastean. As de satellytmjittingen ferkeard binne, wie it hiele alarm basearre op defekte apparatuer. Fersekeringsbedriuwen en havenoerheden meitsje har al klear foar hegere seespegels, sûnder op de wittenskippers te wachtsjen. It ICCS is fan doel yn septimber nije satellytgegevens frij te jaan nei it rekalibrearjen fan har ynstruminten tsjin trije moanne boaiôflêzing. Dy test sil de skeptisy net it swijen oplizze. It sil allinne bewiize oft it spesifike satellyt-systeem ferkeard wie, net oft de opwaarming sels plakfûn hat. De oseaan sil dochs bliuwe opwaarmen. De fraach is oft immen begrypt hoe flug.

The ocean warmed 0.24 degrees Celsius per decade from 2010 to 2025, according to satellite measurements published last month by the International Centre for Climate Science. That rate runs 40 percent faster than the average prediction from twelve major climate models tested by the same group. The finding has split the research community into two camps: those who believe the warming spike is real, and those who suspect the satellite instruments have drifted out of calibration.
Japanese and American researchers have flagged a possible fault in the Argo buoy network, which measures subsurface temperatures across the world's oceans. Between 2020 and 2023, technicians replaced sensors on thousands of buoys without running proper crossover tests to check whether new instruments gave different readings than old ones. This blind spot could explain part of the temperature jump, though researchers disagree on how much. Some models now include a 10 to 15 percent correction factor for potential sensor drift. Others ignore the problem entirely.
Climate centers in Germany and France have pushed back harder, claiming the warming is genuine and that older models underestimated feedback loops in deep water. They point to rising sea surface temperatures measured by independent buoy systems and ship records going back to the 1970s. Yet those same independent systems show a much slower warming trend than the satellite data does, which creates its own puzzle. None of the major institutions have published a final explanation that the others accept.
The disagreement matters for policy. Governments use these ocean temperature forecasts to set coastal flood projections and carbon budgets for the coming decades. If the warming is real, many countries will have to tighten emissions cuts far sooner than their current plans allow. If the satellite readings are wrong, the entire alarm was based on faulty gear. Insurance companies and port authorities have already begun bracing for higher sea levels, without waiting for the scientists to settle the dispute.
The ICCS plans to release new satellite data in September after recalibrating their instruments against three months of buoy readings. That test will not silence the skeptics. It will only prove whether the specific satellite system was wrong, not whether the warming itself happened. The ocean will keep warming either way. The question is whether anyone understands how fast.
