8/ snip "Bill Rees is one of a number of #climate scientists who portray #climatechange as one symptom of a larger planetary problem of ecological #overshoot. In this excellent lecture (https://youtu.be/9oVTHKzC7TM) he briefly touches on: ocean acidification, freshwater contamination, #deforestation, soil #erosion, #desertification, overfishing and species #extinctions."

Key quotes:

“It’s not just mammals. Wild bird populations are also tumbling. Domestic poultry now constitute 70% of the world’s avian biomass. Average populations of thousands of monitored species of wild vertebrates, birds, fish, mammals, amphibians, have declined ~60% since 1970. Populations of #invertebrates, including essential #pollinators, are also in free-fall: Butterflies down 53%; beetles down 49%, bumblebees down 46%… All species monitored by WWF are down 68–70% in just 50 years.”"

South America is burning. Why? Climate change is a big factor, obviously. Also, it's due to previously well-intentioned planting of non-native species which are fire-prone rather than fire-resistant. For example, Bogota planted lots of eucalyptus around the city to prevent erosion during the 20th century.

Just points to the importance of looking to indigenous ecology for cues about how best to adapt to the challenges of #ClimateChange.

my favourite #goodNews story of the week cos it involves #otters :awesome: :blobheartraccoon:

"A great example of how saving one #species can have a domino effect on the restoration of a whole #ecosystem. In California’s Monterey Bay, efforts to bolster sea otter populations are saving local salt marshes because the otters feast on the burrowing crabs that cause erosion. The sea otters have consumed enough of the crabs to slow the #erosion almost to a halt."

#Texas #border city on edge as Gov #Abbott dials up battle w/ #Biden

A century & a half ago, Confederate Gen Joseph Orville Shelby splashed into the wild waters of the Rio Grande off this border city & fled to Mexico, refusing to surrender to Union soldiers.
Now the park named in his honor (?) has become a front line in a feud between the #state & the #federal govt — a power struggle over who ultimately has the right to control the border….

The transformation of the city’s riverbank into a #militarized zone is harmful, residents said. Soldiers changed the #river’s flow when they bulldozed islands & pushed the land toward #Texas to keep #migrants from gathering on them. The #environmental costs & the amount of #erosion are still not known.

“They’re destroying the river…,” said Jessie Fuentes, who owns a kayaking & canoe biz but is nervous about taking customers out because of all the #RazorWire …beneath the river’s surface.

photos - Former location of the Cascada San Rafael lava-dam waterfall and knickpoint on the Río Coca, viewed facing upstream. (a) Pre-collapse morphology of the waterfall, in 2012 (image from Ecuador Ministry of Tourism). Accommodation space upstream of the lava dam was filled with sediment. (b) The site was on 2 February 2020, shortly after a sinkhole (upstream of lava dam) captured the river. Dashed line shows the approximate location of the unconformable contact between the lava flow and underlying volcaniclastic avalanche deposits. (c) The site was on 22 February 2021 during the incipient collapse of the remaining arched edifice of the lava flow. (d) Later on 22 February 2021 after full collapse of the lava arch. (e) The site on 25 February 2021, shortly after the river overtopped and eroded through the debris dam. Photographs in (b) through (e) provided by the Corporacion Electrica del Ecuador.
map and chart - (a) Detailed map of the study reach (shown within box in Figure 1a), with river kilometres (rkm) shown referring to distance downstream of the Coca Codo Sinclair (CCS) dam and diversion intake. (b) Subsurface geologic cross-section of the study reached from rkm 0 to 22 (annotated using field observations of the authors and borehole information from INECEL [Instituto Ecuatoriano de Electrificacion], 1992). Dashed line shows the riverbed profile as of 2 December 2022, 1,034 days after the failure of the Cascada San Rafael knickpoint. Prior to the loss of the knickpoint in February 2020, the accommodation space upstream of the Cascada San Rafael had entirely filled with sediment. Geologic units are abbreviated as volcaniclastic breccia (Br), cohesive volcaniclastic avalanche deposits (CoAv), loose volcaniclastic avalanche deposits (LoAv), ancient alluvial deposits (All), lacustrine sediments (Lac), debris-flow deposits (Deb, a thin deposit around rkm 8–8.5). Lava flow, recent alluvial deposits and Mesozoic bedrock are also shown.

Guten Morgen Fedinautinnen,
Ich fürchte heute werden schlimme Dinge passieren. Diese Furcht teile ich mit Menschen aus der Landwirtschaft hier vor Ort. Des Weiteren fürchte ich, dass danach eine ganze Berufsgruppe wieder über einen Kamm geschoren wird. Auch die, die sich distanzieren. Selbst die, die heute nicht demonstrieren gehen. Die Bauern, alles rechte Klima-Schweine wird es , leider auch hier, wieder heißen. Weil es so einfach ist alle in einen Topf zu werfen. Viele Landwirt
innen haben aber auch Angst vor dem, was heute passieren könnte. Aber sie wollen auch auf ihr Recht zu demonstrieren nicht verzichten. Und den Grund kann ich verstehen. Durch die Streichung der Subventionen wird der Diesel zwar teurer, aber es wird kein Tropfen weniger verbraucht. Es gibt kein Programm zum Umstieg. Keine Anreize auf andere Maschinen umzusteigen und wahrscheinlich nicht einmal genügend elektrifizierte Maschinen, damit alle umsteigen. Den Umstieg können sich Agrarriesen leisten, aber keine bäuerlichen Kleinbetriebe. Aber auch da zu unterscheiden ist vielen zu anstrengend. Dieser Diskurs ist dermaßen durchtränkt von Dualismus, das es weh tut. Viele Landwirt*innen sehen das Problem, dass es auch in ihren Reihen mittlerweile Rechte gibt, die es natürlich leichter macht, ihre Proteste zu kapern. Aber es ist ein bisschen wie bei der Diskussion über die Problematik mit Rechtsextremismus im Osten in den letzten Jahren. Erstmal alle unter Generalverdacht stellen, dann kommen die Mauer hoch Rufe, anstelle denen, die stabil demokratisch sind, zu helfen, sie zu unterstützen. Seit Jahren wird die demokratische Zivilgesellschaft im Osten alleingelassen. Denn es ist viel bequemer sich zu empören und mit dem Finger auf andere zu zeigen. Aber so funktioniert Demokratie leider nicht.So ist das Problem Rechtsextremismus ein gesamtdeutsches Problem geworden, wie man bei den letzten Landtagswahlen sehen konnte. Aber ich bin mir sicher, diese Einsicht wird nur bis zu den Landtagswahlen im Herbst reichen.
Kommt gut in den Tag und seid nett zueinander 🥰

When we think of #food, we often aren’t paying attention to soil, but it’s actually what sustains our global food system.

Unfortunately, #ClimateChange, unsustainable farming practices & more are degrading soil around the world.

I don’t get to see each episode of Serving Up Science until they are published, but I like this new video. And I’m so glad they let me talk about soil health. https://youtu.be/FnOHwq6iSpk?si=5umwoGQU7DFrdhCD

Destroying Hamas is a political objective, not a military one.
Even if Israel claims success after assassinating senior Hamas figures, destroying their arsenal and tunnels, and dismantling their administration, they have not said what they will do the day after “victory”.
The Gaza strip will still be there, albeit mostly in ruins. The population who survive the war will still be there, mourning new losses of loved ones and their homes. And the poverty and other deprivations that fed Hamas will only have intensified.
The national rage, the massing of military might, looked disturbingly familiar to US president Joe Biden, who warned Israel last week:
“Justice must be done. But I caution this – while you feel that rage, don’t be consumed by it. After 9/11, we were enraged in the United States. While we sought justice and got justice, we also made mistakes.”

Even if the could be pressured or bribed into considering taking control, it is far from clear if they would be accepted, or able to do it.

A government installed by the Israeli military would not be seen as legitimate.

The are already widely resented in the for their weakness in the face of Israeli authorities, for being inefficient, unrepresentative and riddled with corruption.

And though the majority of Gazans were not old enough to vote when lost elections to in 2007, there is no reason to think they have become more popular.

The only idea floated by Israeli politicians and officers for Gaza’s future, an force, seems rooted more in wishful thinking than reality.
“It seems that the war is going to be very, very and we have to take into account the , the risk of conflict into the wider region, the of support and the question to whom we are going to pass in Gaza – for example if we have to pass it potentially to some Arab-led force,” said former prime minister Ehud .

Cape Blanco, Oregon’s westernmost point (and also its windiest)…is composed of layers of uplifted marine sediments ranging in age from 80 million years at the bottom to less than 500,000 years at the top…forming an elevated terrace (60m) that is the focal point for erosion.
