Western U.S. Cities Open Wallets in Quest for Water Understanding urban water supply costs is essential. Discover Queen Creek's significant investment in securing water resources.

At the same time, some of these kinds of efforts are already happening, though at a more "local" level. Great reporting here from Brett Walton on water deals across the western US www.circleofblue.org/2026/supply/...

🌊 Measuring equity is key to better ocean governance.

A new study introduces the Ocean Equity Index (OEI), a systematic way to assess and improve equity in ocean initiatives, projects, and policies, from local to global scales.

WEF Alternative Speech '26 – Jan 21, 2026–Jan 21, 2026 A contrasting vision to Donald Trump’s speech at the World Economic Forum 2026.

At WEF, speeches by world leaders totaled almost four hours of speaking time: and not one mentioned climate change.

So @wedonthavetime.bsky.social organized an alternative WEF speech by some of the world’s leading scientists and systems thinkers. It took place on a pile of snow.

Despite years of "economic anxiety" discourse, the core drivers of Trump support have always been bigotry and misinformation.

AI is Destroying the University and Learning Itself Students use AI to write papers, professors use AI to grade them, degrees become meaningless, and tech companies make fortunes. Welcome to the death of higher education.

β€œThe math is brutal and the juxtaposition stark: millions for OpenAI while pink slips go out to longtime lecturers. The CSU isn’t investing in educationβ€”it’s outsourcing it, paying premium prices for a chatbot many students were already using for free.β€œ

5 hurricanes.
4 saw Extreme Rapid Intensification (58+ mph in 24 hrs).

Sri Lanka declares state of emergency after floods leave hundreds dead and many missing The president says it is the "most challenging natural disaster" in the country's history.

We’ve always had floods – but as the world warms, they’re becoming more intense and more severe.

We’re all in harms way – but those who don’t have a safe place to live, or can’t take food and water for granted, are always most vulnerable.

Geologic map of the Bay Area, showing an anastomosing network of strike-slip faults. In a second map, the blocks of crust defined by these faults are restored to their positions at 34 Ma, with arrows labeled as to the distance they have moved since that time. Extremes: Mt. Diablo has moved 175 km southeastward, while Point Reyes has moved 290 km northwestward.

Cool inset map from this "Geologic Map of the San Francisco Bay Region," by Graymer, et al. (2006). ngmdb.usgs.gov/ngm-bin/pdp/...
It shows the blocks of crust sliced & diced by Bay Area faults, and how much & in what direction they have moved in the past 34 million years.

European summer heatwaves are worsening unevenly

Central & Northern Europe: more moisture stress = stronger, more variable heatwaves

Southern Europe: drier but more stable = weaker extremes

This is a literal nightmare.

As a global civilization, we haven't even begun slowing the rise in greenhouse gases yet. Starting a *privatized* geoengineering project at this point in history will make the global climate crisis even worse.
