Wow, the article starts off straight away by highlighting the already - crystal clear - dead end we find ourselves in. With energy efficiency measures and conventional materials alone, it blows the budget (with it, our climate). Note that in the SMART pathway, new con fades out & reno takes over.

Abstract
The European Union aims to reduce greenhouse gas emissions by 55 percent by 2030 relative to 1990 and achieve climate neutrality by 2050. Yet, translating these targets into pathways for buildings and construction is challenging across diverse national contexts. We model building stocks for the twenty-seven Member States of the European Union and evaluate 4096 life cycle emissions scenarios, considering national capacities. Here we show that, over 2020–2050, achieving these targets would require avoiding 8.53 billion metric tons of carbon dioxide equivalent, approximately ten years of emissions at 2020 levels. Mostly relying on improving energy efficiency and material production would exceed national capacities by 2.72-billion-ton, 32 percent of the required reduction. A combined approach that also reduces per capita space demand, applies circularity measures, and uses bio‑based materials could achieve an additional 2.19 billion tons within national capacities. For each country, we identify the strategies that maximize projected reductions to inform policy design.3 pathways, named HOPE, COPE, SMART

Als Info: Klimaschutz & Klimaanpassung sind beide unverzichtbar – deshalb sollten beide im Klimagesetz verankert sein. Ohne Klimaschutz stoßen wir an die Grenzen unserer Anpassungsfähigkeit. Ohne Klimaanpassung sind wir auf die Folgen des bereits veränderten Klimas nicht ausreichend vorbereitet.

Alle reden über die Hitze, aber niemand über den Klimaschutz! Die aktuelle Hitzewelle würde es ohne den Klimawandel nicht geben. Während Forderungen nach mehr Anpassung laut werden, spielt Klimaschutz in der Debatte kaum eine Rolle. www.derstandard.at/story/300000...

Der Bevölkerungsschutztag 2026 wird zum Schutz der Bevölkerung abgesagt. Was für eine Ironie. Und die Politik? Schweigt laut. :| Die Absage ist natürlich sinnvoll. Aber was CDU/CSU und SPD auch da weiterhin erlauben mit Frau Reiche und ihren Komplizen... 🔥

Indeed. But the industrial carbon capture schemes have been wildly unsuccessful — and have maybe even helped delay more effective forms of climate action. A ton prevented today is a ton you don’t need to try — and probably fail — to remove tomorrow.

this is what is insane abt this case and these sentences. this isn't a sandwich throw. real violence happened here. a cop got shot. but by framing the protest as a conspiracy people who literally were uninvolved in the violence got de facto life sentences

Two defendants who received 50 years each, Savanna Batten and Elizabeth Soto, were never accused of helping plan the demonstration here. They arrived separately, left the protest when guards asked them to, and were not accused of any act of violence talkingpointsmemo.com/news/prairie...

the world falling apart sucks real bad, but it's amazing that New York somehow slipped into an Disney Channel Original Movie alternate reality where our problems are fixed by Mayor Socialism and the Power of Friendship wins basketball championships.

Model-based studies often reflect Global North narratives in scenario databases, assume persistent inequalities, obscure ethical or normative choices behind justice, & fail to systematically include stakeholders & scientists from the Global South. www.sciencedirect.com/science/arti...

This is one of the most important benefit of the carbon budget framing, because it naturally leads to a discussion of equity and historical responsibility. Allocation is an explicitly political process, and the budget makes these choices explicit.

The retirement of RCP8.5 — former worst-case climate scenario has been in the news recently, and I’ve seen a lot of good explainers about this very misunderstood modeling tool. But an angle I think has been missing: the former best-case scenario is also out. My story: www.eenews.net/articles/the...

The worst-case climate scenario is gone. The catch? The best case is, too.
