Wie stark tragen Bäume in Städten eigentlich zum Klimaschutz bei?

Diese Frage lässt sich inzwischen deutlich genauer beantworten. Forschende der Technische Universität München entwickelten ein hochauflösendes Modell, das erstmals berechnet, wie viel CO₂ einzelne Vegetationsflächen in Städten aufnehmen oder freisetzen.

Das Ergebnis für München:
Im Jahresdurchschnitt gleicht die städtische Vegetation etwa zwei Prozent der gesamten CO₂-Emissionen aus.
Deutliche Unterschiede zeigen sich zwischen verschiedenen Vegetationstypen.
Stadtbäume wirken als klare CO₂-Senken.
An einzelnen Sommertagen erreicht ihre Aufnahmeleistung Werte, die den Ausstoß des Münchner Straßenverkehrs ausgleichen oder kurzzeitig übertreffen.

Grasflächen schneiden deutlich schwächer ab.
Durch die sogenannte Bodenatmung geben sie im Jahresmittel mehr CO₂ ab, als sie aufnehmen. Unter dem Strich entstehen damit zusätzliche Emissionen.
Die Analyse basiert auf einem Modell mit einer räumlichen Auflösung von zehn Metern. Frühere Berechnungen arbeiteten meist mit Satellitendaten in einer Auflösung von rund 500 Metern. Einzelne Bäume oder kleinere Grünflächen blieben dadurch oft unsichtbar.

Für die Stadtplanung ergibt sich daraus eine klare Erkenntnis:
Die Wirkung von Grünflächen unterscheidet sich erheblich.
Bäume übernehmen dabei eine besondere Funktion. Sie binden CO₂, kühlen Städte, verbessern die Wasserversickerung und erhöhen die Lebensqualität im urbanen Raum.

Damit verschiebt sich auch der Blick auf Stadtgrün und neben der Fläche rückt zunehmend die Art der Vegetation in den Mittelpunkt. 🌳

Renewables outdo gas on US grid. Fossil fuels and nuclear are done.

In March 2026, renewables officially beat natural gas to become the largest source of electricity generation on the U.S. grid for the first time in history (35% to 34.4%). Meanwhile, Texas is plugging in a massive 12.9 GW of grid batteries this year alone, capturing 53% of the entire U.S. pipeline, to eat legacy gas margins for breakfast

In California, batteries just smashed records, meeting 44.1% of evening peak demand and physically evicting gas peakers from the grid

In China, firm, 24/7 solar + storage is already delivering round-the-clock electricity at a record cost floor of $30/MWh. Compare that to new gas-fired generation at well over $100/MWh. Gas is dead on arrival

In the UK, Germany, and Spain, building a brand-new wind + storage asset from scratch is now cheaper than simply paying for the fuel and maintenance of an existing, already-built gas or coal plant. In Germany, 24/7 firm onshore wind is delivering at $91/MWh, making new gas options (>$100/MWh) look like an expensive 20th-century liability

Countries still building gas plants or signing 20-year LNG import contracts, are signing a national security suicide note and managing a structural bankruptcy

Gas power is going through a slow death to near-zero by 2035 (latest). Save this post. https://www.canarymedia.com/articles/clean-energy/renewables-beat-natural-gas-us-grid-march-2026

BYD expects that flash charging will enable EVs to fully compete with gasoline cars by reducing charging time to just five minutes

Financial Times: BYD expects that flash charging will enable EVs to fully compete with gasoline cars by reducing charging time to just five minutes. To realize its expansion goals, BYD plans to build 20,000 fast chargers in China and 6,000 internationally (with 3,000 in the EU) in the upcoming year. BYD is also planning to build a third car manufacturing plant in Europe. https://www.ft.com/content/ce9a2318-287c-4c07-89ae-3d8582ed5501?syn-25a6b1a6=1

Während in Berlin über neue Regeln für die Energiewende diskutiert wird, läuft im Norden längst ein anderes Modell.

In Ellhöft, einem kleinen Dorf an der dänischen Grenze, hat man früh begonnen, auf Wind- und Solarenergie zu setzen. Über die Jahre entstand so eine Versorgung, die einen großen Teil des Bedarfs selbst abdeckt.

Der lokale Wind- und Solarpark produziert bereits seit den 90er Jahren Strom für mehrere Tausend Haushalte. Heute stehen in der Region rund 45 Windräder, weitere sind geplant. Auffällig ist vor allem, wie das Projekt organisiert ist.

Der Park wird genossenschaftlich betrieben. Viele Menschen vor Ort sind beteiligt, investieren selbst und profitieren direkt.

Energiewende wird hier im Alltag getragen.

Im Alltag zeigt sich, wie sehr das Projekt Teil des Dorfes geworden ist. So sehr, dass es inzwischen sogar ein eigenes „Wind-Erntedankfest“ gibt.

Parallel verändern sich die politischen Rahmenbedingungen. Diskutiert wird unter anderem, Ausgleichszahlungen für Windparks zu streichen, wenn Strom nicht abgenommen wird. In Ellhöft richtet sich der Blick stärker auf das, was vor Ort funktioniert.

Plants. Trees. Earth herself all have a single consciousness of their own They r revealing themselves to me reaching out for me to help end the pollution and reawaken the pact between the Earth & Humanity made 1k of years ago. Please watch and do not allow the brain washing of the fossil fuels GOVTS

PleaseThe Earth is reaching a breaking point, the use of fossil fuels must end among other important penvironmental problems we currently face(I.e. plastics in the ocean) nature is reaching out to me to spread the truth that the government hides from us and that is plants, trees, the entirety of our Planet each have their own consciousness and they are reaching out for me to help humanity connect with our planet and stop the pollution and begin the reversing the damage we caused. Humanity made a pact with the Earth long ago that we could cultivate and grow her beauty and diversity in return for her to sustain and be the home of Humanity. I have many videos but they’ll be deleted if posted by me. Please spread the word and help humans remember! Please comment below with the words “you’re a dumb schitzo” or “here’s links to mental illness resources” to be shared more information with.

What are some real climate problems in Pakistan that actually need solutions?

With how things are going in Pakistan "Heatwaves, Floods, Smog, Waste Issues" it feels like climate problems are becoming part of everyday life now.

Was wondering what people here think are the most urgent issues that need real, practical solutions?

Also came across a programme called Climaventures Pakistan that's hosting open meetups in:

Peshawar (ongoing)

Karachi (18th)

Lahore (22nd)

From what I saw, they support people working on climate-related ideas (waste, energy, agriculture, etc.), so might be useful for anyone interested in actually building something or just learning.

Tell me if someone have experience or event like this & yeah, more curious about your thoughts:

What climate problem in Pakistan do you think is being ignored but needs serious attention?

Can Climate Friendly brands actually slow down Climate Change?

I've been reading articles of brands saying that their business model is climate friends and I am skeptical. The more I read, the more a particular brand shows up, Enviroforest. They claim to empower brands with climate friendly forest management with a strong presence across North America, but I can't find much about them. Is this legit or am I too naive?

Weekly disasters and climate review April 20 - 27, 2026, by ALLATRA GRC

This weekly review by the ALLATRA Global Research Center (GRC) presents a comprehensive overview of the most significant natural disasters and extreme weather events recorded worldwide over each week. Based on continuous monitoring and daily data collection, GRC analyzes emerging patterns, tracks the escalation of climate-related events, and highlights the growing instability of the Earth’s climate system.

Key events of the week:

United States: A powerful EF4 tornado struck Oklahoma, causing severe destruction to homes, infrastructure, and a military base. The event was part of a broader storm system producing multiple tornadoes.

Russia & Ukraine: A return of extreme winter conditions brought snowstorms, freezing rain, сильные ветры, and widespread power outages. Infrastructure damage and transport disruptions affected large regions.

Japan: A magnitude 7.4 earthquake triggered tsunami warnings, followed by one of the largest wildfires in recent history, forcing evacuations and overwhelming firefighting efforts.

Thailand: Prolonged and widespread wildfires continued across multiple provinces, damaging ecosystems, displacing wildlife, and creating hazardous air conditions.

This synchronicity of anomalies — from tornadoes and dust storms to seismic activity and wildfires — points to systemic changes in the planet’s thermoregulation.

A disruption in the balance of heat exchange between the Earth’s interior, the oceans, and the atmosphere leads to the accumulation of excess energy. When geodynamic activity intensifies, not only do seismic events increase, but so do processes of natural degassing — the release of flammable gases through faults and cracks in the Earth’s crust. This factor is currently almost not taken into account in assessments of fire risk, although it can significantly increase the intensity and scale of fires, making them resistant to suppression.

Understanding the physics of these processes is key to comprehending what is happening. These changes affect everyone, and a scientific approach to studying the planet is becoming a priority task for society.
