"In particular, a large fall in the price of panels in 2023-24 pushed us into the current era of what Jones calls "offensively cheap" solar. "A panel in itself is just so unbelievably cheap," he says. "It's well under $100 (£75)… and that's going to keep you generating electricity for 30, 40 years"

New England has enjoyed a very nice stretch of quiet, mainly sunny and basically quintessential October weather for a couple weeks. The other shoe will drop eventually, and this may occur heading into November. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx newenglandstormcenter.substack.com/p/when-will-...

Meh. Was told there’d be water. 1 ⭐️

The only thing keeping this whole week from being persistently mild will be a couple cold fronts. The first of which is moving into northern New England this afternoon, as evidenced by sharply cooler temps across the north. #MAwx #CTwx #RIwx #NHwx #MEwx #VTwx

When park staff took down the summit sign noting the importance of Cadillac Mountain to Maine's Indigenous people at the orders of Interior Secretary Doug Burgum, they also unraveled some of the trust that took decades to build between Acadia National Park and the Wabanaki people.

I have a message to all bots that came out of the shadows today during the BC Provincial Election. 😏

Having a whale of a weekend. Another outing with the Dolphin Fleet out of Ptown. SO many 🐋🐋! (And big swell. Multiple people 🤮) Another research trip for my next book about humpbacks. So lucky to live near where they thrive in the Stellwagen Bank National Marine Sanctury! 🎥 to come #OceanDevotion

1.6 million Americans, including many of you, weighed in during the public comment period which ended on Oct. 6 calling on the U.S. Dept. of Agriculture to retain #RoadlessRule protections for our rivers and clean water. 🌲 Read what's next: www.americanrivers.org/2026/10/prot...

In much of the country, the AI boom is driving the construction of hyperscale data centers. Not so much in New England. But change is coming. Here's how some in the region are preparing.

🎉 Congratulations to Riverkeeper President Tracy Brown on being named one of Westchester Magazine’s 25 Most Influential People! We’re proud to celebrate Tracy’s leadership and her unwavering commitment to a future where everyone can safely swim in, fish, and drink from the Hudson. 💙

We protect water together. This September, the Riverkeeper team joined 125 Waterkeeper groups from around the world in Ecuador to share knowledge, strengthen partnerships, and learn from communities working to protect their waterways. 🌎💧 Read more:https://ow.ly/mqhe50ZVA5f

🧂 Before winter arrives, it’s time to rethink how we use road salt. At the NYS Salt Summit hosted by the Lake George Association, Riverkeeper joined highway departments, waterkeeper partners, and state leaders to explore practical solutions to road salt pollution.

What can an underground stream reveal about an island’s geology? Harrison’s Cave in Barbados stretches at least 2.3 km through crystallized limestone. Groundwater dissolved the rock over time, creating passages, streams, waterfalls, and pools. 🧭 geosociety.co/GC6TTMD #InternationalEarthCacheDay

GSA Connects 2026 does not happen without the people who show up before the sessions start and stay until the last attendee leaves. To our staff, volunteers, and GSA Foundation team—thank you! We are proud to work alongside a team this dedicated.

Increasingly beaver dams are promoted by gov't and env orgs to add ecosystem resilience, creates habitat for native fish & provide a natural break to slows wildfires. This is increasingly vital as climate change and overuse make the US West drier, experts say. 🌎 🧪🌿 apnews.com/article/beav...

Americans are moving south! This fascinating map shows the biggest interstate migration flows between 2021 and 2025. California is losing residents to Texas, Arizona and Nevada, while New Yorkers are heading to Florida and New Jersey. Florida and Texas are the big winners.

NYCP Parks staff joined us to visit to three #damremoval projects along #Quassaick Creek: Holden Dam, next slated for removal Walsh Road Dam, planned for a future phase & Strooks Felt Dam, which Riverkeeper removed in 2020. Sharing what we’ve learned makes our work across the watershed stronger.

The 11th annual NY Salt Summit brought road crews, lawmakers, scientists, and clean water advocates to Albany to seek solutions. #Salt #Salinization  www.riverkeeper.org/news-and-eve...
