    1. Die Daten des europäischen Klimaservice Copernicus ergeben, dass die Temperaturen erstmals über 12 Monate mehr als 1,5° über dem vorindustriellen Durchschnitt lagen. 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. Zusammenfassender Artikel über Studien zu Klimafolgen in der Antarktis und zu dafür relevanten Ereignissen. 2023 sind Entwicklungen sichtbar geworden, die erst für wesentlich später in diesem Jahrhundert erwartet worden waren. Der enorme und möglicherweise dauerhafte Verlust an Merreis ist dafür genauso relevant wie die zunehmende Instabilität des westantarktischen und möglicherweise inzwischen auch des ostantarktischen Eisschilds. https://www.theguardian.com/world/2023/dec/31/red-alert-in-antarctica-the-year-rapid-dramatic-change-hit-climate-scientists-like-a-punch-in-the-guts

    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.

    1. Auf Z. Hausfather gestützt, wird festgestellt, dass sich die Temperaturerhöhung des Nordatlantik nicht durch die Ursachen wie weniger Saharastaub und Schiffs-Aerosole allein erklären lässt, sondern sie auf den anthropogenen Klimawandel zurückzuführen ist.

    1. 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. Die Oberflächentemperaturen der Ozeane haben im April einen neuen allzeitrekord erreicht noch nie in der aufgezeichneten Geschichte haben sich die Temperaturen so schnell und so stark erhöht wie im Augenblick. Es gibt deutliche Anzeichen für ein starkes El Niño-Phänomen in diesem Jahr und Vermutungen, dass deshalb die 1,5 Grad-Grenze schon im kommenden Jahr überschritten werden wird. https://www.bbc.com/news/science-environment-65339934

    1. Aboard the research ship RV Laurence M. Gould, cruising along Antarctica’s west coast, according to Carlos Moffat, chief scientist, Palmer Long Term Ecological Research Program: “Even as somebody who’s been looking at these changing systems for a few decades, I was taken aback by what I saw, by the degree of warming that I saw… We don’t know how long this is going to last. We don’t fully understand the consequences of this kind of event, but this looks like an extraordinary marine heatwave,”

    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.

    1. Reconstructions from sedimentary records show that canyons undergo flushing infrequently (102- to 103-year time scales), and on passive margin canyons, this might occur only during periods of glacially lowered sea level and direct sediment supply (7, 12).

      This is interesting!

    1. 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.

      This is interesting!

      This is an interesting SaaS system for exploring how to create good moderation systems.

    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).
