Wishing you all a happy Carl Sagan Day (born this day in 1934).

Fascinating to see his note summarizing the key topics he planned to discuss during his 1977 meeting with President Carter. ("Wonder"!) 🧪🔭

If we do not seriously move away from burning fossil fuels, hurricanes like Melissa will only become worse. Already today Melissa tested the limits of what preparedness and adaptation can do. These limits are very real for everyone in the Caribbean. www.worldweatherattribution.org/climate-chan...

NEW: Common Crawl, the massive archiver of the web, has gotten cozy with AI companies and is providing paywalled articles for training data. They’re also lying to publishers who have asked for material to be removed. “The robots are people too,” CC’s exec director told us when we asked about this.
The Nonprofit Feeding the Entire Internet to AI Companies
Common Crawl claims to provide a public benefit, but it lies to publishers about its activities.

New: The FBI is quietly urging ICE agents to properly ID themselves in the field.

In a bulletin to law enforcement last month, it warned of criminals posing as ICE to rob, rape, kidnap—a problem it says now demands national coordination to confront.

By me & @carolinehaskins.bsky.social:
FBI Warns of Criminals Posing as ICE, Urges Agents to ID Themselves
In a bulletin to law enforcement agencies, the FBI said criminal impersonators are exploiting ICE’s image and urged nationwide coordination to distinguish real operations from fakes.

Grateful to Peter for his stellar data analysis work, which produced maps letting people see how many lbs. of two highly toxic pesticides, including the carcinogen 1,3-D, growers applied near their kids' schools. It's an invaluable public service CA regulators should have been providing all along.
