Face aux records de température, à la mortalité des forêts et aux sécheresses, ils dénoncent l'illusion d'une adaptation infinie, les milliards d'aides publiques accordés aux énergies fossiles, le cadrage défaillant des médias dominants et la dimension coloniale de la transition énergétique https://www.youtube.com/watch?v=JHoD1WDMX2A&t #Climat #MassExtinction #ecology #environment #Climate #ClimateJustice #EndFossilFuels #ClimateEmergency #ClimateChange #ClimateCrisis #ClimateBreakdown

3 million years ago, greenhouse gas was lower (at 360ppm). Temperatures were warmer, and sea levels were 20 meters higher. Professor Gavin Foster: “The reason we don’t see #Pliocene-like temperatures and sea-levels yet today is because it takes a while for Earth’s @climate@a.gup.pe to fully equilibrate (catch up) to higher CO2 levels and, because of human emissions, CO2 levels are still climbing.” Julia Steinberger: https://www.resilience.org/stories/2020-07-15/cogs-in-the-climate-machine/ #massExtinction #climate #globalHeating #climateBreakdown

"Closely spaced or overlapping El Niño events create cumulative cloud suppression. Each El Niño phase actively reduces low-level stratocumulus and trade-wind cumulus clouds over vast tropical and subtropical ocean areas as part of the Bjerknes feedback loop. When the next El Niño develops before full cloud recovery during intervening La Niña or neutral conditions, the albedo loss becomes progressively more persistent, producing the observed multi-decadal linear decline. […] Major El Niño periods (especially 2015–16 and 2023–24) coincide with accelerated albedo drops and incomplete recoveries." Ford, Gillon (2026).

Greenhouse forcing: "We find that the likelihood of the occurrence of climate regime shifts significantly increases in the context of super El Niño events due to their remarkable climate perturbations. This higher probability is detected across various climate elements, such as surface air temperature, sea surface temperature, and surface soil moisture. In addition, we suggest that this boost effect of super El Niño events on climate regime shifts will be greatly amplified under future greenhouse warming." Xue, A., Geng, X., Jin, FF. et al. (2025).

There is a layer in Late Triassic rocks in Europe called ‘the dark zone’, because it's full of darkening of pollen and spores. Its origin is in forest collapse and intense fires during the end-Triassic mass extinction. Link: https://www.nature.com/articles/s41561-026-02048-4 #Triassic #MassExtinction #Paleoecology #Forest

Let's say something killed ~90% of life on a planet, like in the Great Dying here on Terra. How long is it going to take the ecology to recover, and where will it start? (~5Myr and surprisingly heavy on the top of the food chain). Link: https://www.nature.com/articles/s44185-025-00117-2 #PTB #MassExtinction #Paleoecology #Recovery

Whether it's Doug Ford, Mark Carney, or Pierre Poilievre, Canada is in the midst of a dystopia https://www.youtube.com/watch?v=TnWPUG2Q5UE #Canada #CanPoli #CDNpoli #MassExtinction #ecology #environment #Climate #ClimateJustice #EndFossilFuels #ClimateEmergency #ClimateChange #ClimateCrisis #ClimateBreakdown

I was reading about the demand for Full Stack developers and started to think about generalists around mass extinctions. It's something the paleoecological community has been debating; we seem to agree it's not good to be a specialist in bad times.

Good Morning toot from Munich, at 24°C in the shade already at 6 in the morning. In a few hours it'll be 35°C or more - again. Remember the conclusion of the World Weather Attribution Organisation? "A rapid phase-out of fossil fuels is critical if we are to avoid even higher temperatures and their consequences in the future." Or our species and so many others might not see another century. #EndFossilFuels #MassExtinction #HeatWave #WaterShortage
