A quiet EV upside the FT highlights: less noise.

Cities like Beijing and Shanghai are already seeing calmer, quieter streets—and better sleep—as EV adoption rises.

EVs are notably quieter at low speeds, though tyre noise dominates above ~50 km/h.

With the disappointing progress at Cop30, evergreen reminder it isn't "we" or "humanity" failing to address the climate crisis — oil-producing nations and fossil fuel interests are actively obstructing action, despite heroic efforts by developing nations, Indigenous peoples, and many, many others.

First electric cars and buses, now trucks: in the past we were often told that electric trucks would not be feasible.

But the market is picking up speed and electric trucks have become a reality. Expectations are for significant market expansion in the coming years.

Nearly every panel I spoke on this year ended with the same question: "What gives you hope?"

My friends, that question expired years ago. (If you need receipts, my book Saving Us is literally a 300-page answer.)

The real question is: How are you PRACTICING hope?

Because Greta is right ..
A quote by Greta Thunberg stating that, "The one thing we need more than hope is actoin. Once we start to act, hope is everywhere." It's in white font on a blue sky background with puffy white clouds.

A new Nature paper accompanying the Global Carbon Budget finds that the land and ocean sinks are 25% smaller and 7% smaller, respectively, than they would have been without the effects of climate change over 2015-24:
Emerging climate impact on carbon sinks in a consolidated carbon budget | Nature
Despite the adoption of the Paris Agreement ten years ago, fossil CO2 emissions continue to rise, pushing atmospheric CO2 levels to 423 ppm in 2024 and driving human-induced warming to 1.36°C, within years of breaching the 1.5°C limit 1,2. Accurate reporting of anthropogenic and natural CO2 sources and sinks is a prerequisite to tracking the effectiveness of climate policy and detecting carbon sink responses to climate change. Yet notable mismatches between reported emissions and sinks have so far prevented confident interpretation of their trends and drivers 1. Here, we present and integrate recent advances in observations and process understanding to address some long-standing issues in the global carbon budget estimates. We show that the magnitude of the natural land sink is substantially smaller than previously estimated, while net emissions from anthropogenic land-use change are revised upwards 1. The ocean sink is 15% larger than the land sink, consistent with new evidence from oceanic and atmospheric observations 3,4. Climate change reduces the efficiency of the sinks, particularly on land, contributing 8.3 ± 1.4 ppm to the atmospheric CO2 increase since 1960. The combined effects of climate change and deforestation turn Southeast Asian and large parts of South American tropical forests from CO2 sinks to sources. This underscores the need to halt deforestation and limit warming to prevent further loss of carbon stored on land. Improved confidence in assessments of CO2 sources and sinks is fundamental for effective climate policy.
