To begin, I was skeptical. I think that too much energy is invested in creating global products which have low accuracy and are not that useful to policymakers, who rarely get to make global decisions. I mostly agree with arguments made here: www.nature.com/articles/s41...

Even more so, dehumidifiers remain underappreciated. Some portable ACs come with the dehumidifier setting, and you can cut down your energy consumption by ~1/3rd without accounting for the reduced need for cooling (because most of our discomfort is from the humidity).

DuckDuckGo has introduced a new feature allowing users to filter out AI-generated images from search results, addressing growing concerns over synthetic content overwhelming authentic visuals online. 
The filter can be activated through a dropdown in the Images tab, search settings, or by using a dedicated AI-free domain: noai.duckduckgo.com. The system relies on curated blocklists, including uBlockOrigin’s Huge AI Blocklist, to detect and suppress AI-generated imagery. 
While not perfect, it significantly reduces synthetic content visibility. This move sets DuckDuckGo apart from competitors like Google and Bing by giving users direct control over their exposure to AI-generated material.

Unprecedented continental drying, shrinking freshwater availability, and increasing land contributions to sea level rise Drying continents, extreme drought, and groundwater depletion are shrinking water availability and increasing sea level rise.

After a long absence from Twitter, I'm now on Bluesky. Looking forward to sharing thoughts, research, and rants about the lack of attention paid to water. Let's kick this off with a new paper alert. Please share widely. Title says it all. Please help me grow followers www.science.org/doi/10.1126/...

Every time I open LinkedIn, someone from a science agency shares an unplanned (forced) early retirement or RIF. Lately it’s NASA & EPA. In spring, NOAA. I think people have no idea how deep this loss really is. I don’t know what rebuilding federal science looks like, but it won’t be simple or quick.

Graph titled "Water From Land Has Become a Leading Driver of Sea Level Rise." A description below reads: Most of the water lost from drying regions is from groundwater pumping, which ultimately shifts fresh water from aquifers into the oceans. There are two squiggly lines trending upward on the graph, one in blue labeled "melting glaciers," and one in orange labeled "drying land and aquifers." The x-axis is in years, with tick marks every four years from 2004 to 2024, and the y-axis is in mmSLE (Sea Level Equivalent), with tick marks going from -5 to 20 mmSLE. After 2012, the orange line appears to be higher than the blue line. A note below the graph reads: Glaciers refer to the parts of the continents covered in glaciers but excludes the ice sheets of Greenland and Antarctica. Drying land and aquifers refer to the water lost by the continents in areas not covered by glaciers, including river flow and evaporation. Groundwater loss accounts for 68% of the drying in those places.

7/ It’s not just about losing usable water, either. According to a new study based on 20+ years of NASA data, runoff from pumped groundwater, combined with moisture lost to evaporation and drought, is now one of the largest contributors of sea level rise.

Illustration of the process by which groundwater makes its way into the ocean. As water deep underground is pumped out for agriculture (represented by arrows traveling upward towards a field), only a small amount of the water makes its way into aquifers (represented by a small arrow pointing back down towards the ground). On the right side of the illustration, additional arrows show that the rest of the groundwater runs off the fields into a stream that flows into rivers and then the ocean (represented by boats).

4/ Globally, 70% of fresh water is used for growing crops, with more of it coming from groundwater as droughts become more extreme. But only a small amount of that water makes its way back into aquifers.

For some reason it bothers me a lot that this doesn't acknowledge that this graphic is a remake of two sets of very important USGS historical photos documenting & visualizing land subsidence from groundwater withdrawals in CA's Central Valley.

Yes, the USGS work is public domain, but still.
