    1. GCM-dominated approach allows censorship of alternative perspectives,when the models have a common, or at least widespread, problem: lack of realistic sensitivityto injection of freshwater into the upper layers of the ocean.

    1. Zu Beginn der COP16 für Biodiversität hat die Regierung des kolumbianischen Präsidenten Petro verkündet, sie werde Vertreter:innen indigener Völker eine zentrale Rolle in der Konferenz geben. Es ist aber sehr unwahrscheinlich, dass Indigene mehr Rechte bei den Entscheidungen über die Biodiversität der Erde erhalten.werden. – Nur 10% der 196 Unterzeichner:innen des Kunming-Montreal Abkommens 2022 haben bisher die darin vorgesehenen „nature action plans" vorgelegt https://www.theguardian.com/environment/2024/oct/20/cop16-colombia-prepares-to-host-decisive-summit-on-biodiversity

    1. 2023 haben Böden und Landpflanzen fast kein CO2 absorbiert. Dieser Kollaps der Landsenken vor allem durch Dürren und Waldbrände wurde in diesem Ausmaß kaum vorausgesehen, und es ist nicht klar, ob auf ihn eine Regeneration folgt. Er stellt Klimamodelle ebenso in Frage wie die meisten nationalen Pläne zum Erreichen von CO2-Neutralität, weil sie auf natürlichen Senken an Land beruhen. Es gibt Anzeichen dafür, dass die steigenden Temperaturen inzwischen auch die CO2-Aufnahmefähigkeit der Meere schwächen.

    1. Daten sprechen dafür, dass die Eisfläche um die Antarktis in diesem antarktischen Sommer noch mehr schrumpft als 2023. Am 7. September war die von Eis bedeckte Fläche kleiner als vor einem Jahr. Forschende sehen darin ein Anzeichen dafür, dass das ganze antarktische System in einen anderen Zustand übergegangen ist, weil sich die erhöhten Lufttemperaturen jetzt auch auf den Ozean auswirken. Zu den Folgen gehören Veränderungen der Strömungen und ein schnelleres Abschmelzen der antarktischen Gletscher. https://www.theguardian.com/world/article/2024/sep/10/two-incredible-extreme-events-antarctic-sea-ice-on-cusp-of-record-winter-low-for-second-year-running

    1. “For our customer base, there's a lot of folks who say ‘I don't actually need the newest B100 or B200,’” Erb says. “They don’t need to train the models in four days, they’re okay doing it in two weeks for a quarter of the cost. We actually still have Maxwell-generation GPUs [first released in 2014] that are running in production. That said, we are investing heavily in the next generation.”

Jeder Monat seit dem vergangenen Juni war im globalen Durchschnitt der wärmste Monat seit Beginn der Aufzeichnungen. Johan Rockström, der Direktor des Potsdam Instituts für Klimafolgen-Forschung, sprach von einer Warnung für die Menschheit, dass wir uns schneller als erwartet auf die 1,5° Grenze zubewegen. https://taz.de/EU-Klimadienst-Copernicus/!5991185/

    1. Die obersten 2000 m der Ozeane haben 2023 15 Zettajoule Wärme mehr absorbiert als 2022. Die Erwärmung dieser Schichten verringert den Austausch mit den kälteren unteren Schichten und belastet die marinen Ökosysteme dadurch zusätzlich. Bisher sind keine Zeichen für eine Beschleunigung der Zunahme des Wärmehinhalts im Verhältnis zu den Vorjahren zu erkennen. Die Oberflächentemperatur der Ozeane lag im ersten Halbjahr 0,1°, im zweiten Halbjahr aber für die Wissenschaft überraschende 0,3 Grad über der des Jahres 2022. Schwere Zyklone, darunter der längste bisher beobachtete überhaupt, trafen vor allem besonders vulnerable Gebiete.

    1. people generally don't recognize is that forest across the planet has responded in a tremendously helpful way 00:16:29 by absorbing roughly 25% of carbon dioxide from our fossil fuel burning. And we generally talk about this as a positive. "Isn't that fantastic!" But, in reality, it's a stress response.

In einem - leider kostenpflichtigen, aber über Blende zugänglichen - Interview äußert sich die britische Klimaforscherin Helen Hewitt zu den Rekordtemperaturen, die in den letzten Monaten in den Weltmeeren gemessen worden, und zum Rückgang des antarktischen Meereises. Sie weist darauf hin, dass noch unverstanden ist, wie es genau zu den großen Anomalien gekommen ist. Die obersten zwei Meter der Ozeane nehmen 90% der zusätzlichen Energie auf, die durch die von Menschen imitierten Treibhausgase im Erdsystem bleibt.

    1. Notably absent from the debris was plastic from nations with lots of plastic pollution in their rivers. This was surprising, says Egger, because rivers are thought to be the source of most ocean plastic. Instead, most of the garbage-patch plastic seemed to have been dumped into the ocean directly by passing ships.This suggests that “plastic emitted from land tends to accumulate along coastal areas, while plastic lost at sea has a high chance of accumulating in ocean garbage patches”, Egger says. The combination of the new results and the finding that fishing nets make up a large proportion of the debris indicates that fishing — spearheaded by the five countries and territories identified in the study — is the main source of plastic in the North Pacific garbage patch.

    1. Every 60 seconds the equivalent of a lorry-load of plastic enters the global ocean. Where does it end up? Right now, researchers simply don’t know. But in a bid to help find out, an ESA-led project developed floating transmitters whose passage can be tracked over time, helping in turn to guide a sophisticated software model of marine plastic litter accumulation.

      Huh? The plastic ends up in the Garbage Patches - https://en.wikipedia.org/wiki/Great_Pacific_garbage_patch

      This is a surprising and disappointing oversight by ESA.

Although there are reports on CHH peptides in other crustacean taxa such as Armadillidium vulgare (Isopoda)22,23, Daphnia pulex (Cladocera)24 and Daphnia magna15, investigations beyond decapods have remained scant and the sequences of CHH/MIH/GIH genes in other crustacean taxa have remained elusive.

    1. Mackenzie River
      The Mackenzie River is a major river system in northwestern North America. It is exceeded only in basin size by the Mississippi-Missouri system. The entire Mackenzie River system is 2,635 miles long and passes through many lakes before emptying into the Beaufort Sea of the Arctic Ocean. The Mackenzie River alone is 1,025 miles long when measured from Great Slave Lake. It begins at Great Slave Lake where the elevation is 512 feet above sea level. Great Slave Lake can be as deep as 2,000 feet in certain places. It is filled with clear water on the eastern side and shallow, murky water on the western side. The headwaters of the Mackenzie River include numerous large rivers. The drainage basins of the Mackenzie River include the Liard River, Peace River, and Athabasca River. The ice that forms on the Mackenzie River over the winter months begins the break up in early to mid-May in the southern sections. Ice covering some portions of the Mackenzie River can break up as late as the end of May. The Mackenzie River basin is home to a very small and sparse population despite the natural resources available in this area. This area is home to muskrat, marten, beaver, lynx, and fox. Pulpwood and other small conifer trees can be found here. Petroleum and natural gas are usually the underlying reason larger settlements have formed in this area (Robinson 1999).
