Trotz der UN-Vereinbarung von 2023, die globale #Energie aus #Erneuerbaren bis 2030 zu verdreifachen, haben nur wenige Länder ihre Ziele angepasst.
Laut Analyse bleibt die Welt deutlich hinter dem 11-TW-Ziel zurück. Vor allem große Emittenten wie die

So, driving home from a client call & up ahead of me on the freeway I see a giant blue pickup truck flying

I roll my eyes
Get a little closer…
Ok

Scalar and Mean Curvature Comparison on Compact Cylinder
Let $ X $ be a closed, oriented Riemannian manifold. Denote by $ (M = X \times I, \partial M = X \times \lbrace 0 \rbrace \cup X \times \lbrace 1 \rbrace, g) $ a compact cylinder with smooth boundary, $ \dim M \geqslant 3 $. In this article, we address the following question: If $ g $ is a Riemannian metric having (i) positive scalar curvature (PSC metric) on $ M $ and nonnegative mean curvature on $ \partial M $; and (ii) the $ g $-angle between normal vector field $ ν_{g} $ along $ \partial …

‘Net Zero is a Killer’: Meet Reform UK’s New Chair David Bull
Reform UK’s new chairman has repeatedly attacked climate targets as “madness” and “a killer”, supported fracking, and falsely dismissed the role of carbon emissions on heatwaves. David Bull, a TalkTV presenter and former doctor, was appointed as the chair of Nigel Farage’s right-wing populist party this week following the resignation of its previous chair Zia Yusuf. […]

A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE). XIX. The discovery of a spectacular 230 kpc Halpha tail following NGC 4569 in the Virgo cluster
Context. Galaxies fly inside galaxy clusters and ram pressure by the ICM can remove a large amount of the ISM from the galaxy, and deposit the gas in the ICM. The ISM decoupled from the host galaxy leaves a long trail following the moving galaxy. Such long trails track the galaxy motion and can be detected with sensitive data in Halpha. Aims. We study the Halpha tail trailing NGC 4569 in the Virgo cluster. Methods. The initial discovery was made with the deep Halpha imaging data with CFHT, …
