„hocheffiziente Verbrennung“ ist magisch am Gestern klebend.
Verbrennung“ ist im Lichte des
2. Hauptsatzes der Thermodynamik ein Verbrechen an der Zivilisation und der Natur und der Zukunft.

@guido-kuehn.bsky.social ...würden wir uns nicht am Gestern klebend darin gefallen ständig Zukunftstechnologien zu verdrängen, um uns am letzten fossilen Strohfeuer zu wärmen, so als wäre das eigene Haus abzufackeln die perfekte Vorbereitung auf den kommenden harten Winter.

Effiziente Verbrenner gibt es nicht.
Bei E-Fuels geht viel Energie bei der Produktion verloren und der Verbrennungsmotor produziert mehr Wärme als Bewegung. Ein E-Auto setzt die Elektroenergie direkt in Bewegung um und ist deswegen viel effizienter.

Increasing ice melt is amount of heat that is "soaked up" in melting of ice. That cools the ocean, which increases the regional energy imbalance by reducing heat emission to space. This is an amplifying feedback that increases the melt rate.

The price of fossil fuels should include their costs to society, which implies the merit of a slowly rising carbon fee to achieve competition among clean energies, energy efficiency, and carbon capture. Instead, the 1997 Kyoto Protocol

keynote at ATLAS25 James Hansen is warning dangerous feedback loops of Earth Systems Tipping Points (ESTP). , the media and even some of IPCC lead authors. Hansens message is clear – We're running out of time.

Climate change indicators record high (adverse) increasing as
fast as ever, atmospheric CO2 faster than ever
November the third warmest since records began, and likely the third warmest in the last 120,000 years.

This graphic predicts future temperatures, based on continued accelerated warming:
1.50°C by 2026
2.00°C by 2036
2.50°C 2045
2.85°C 2050
Of course, a lot of non-linearities are possible before 2050. Like a net-zero, carbon-free, sustainable vegan utopia. Or the other

Data from CERES for September, 2025, and yet another record low for Earth albedo was set, with the 36-month reaching below 28.70% for the first time, coming in at 28.693%.
Everything is not fine.
