The flow of the Colorado River has shrunk about 20%, and its depleted reservoirs continue to decline. But talks aimed at addressing the shortage are at an impasse, and environmental groups say the lack of information about the closed-door negotiations is a problem. www.latimes.com/environment/...
Millions rely on dwindling Colorado River — but are kept ‘in the dark’ about fixes, critics say
Negotiations aimed at solving the Colorado River's water shortage are at an impasse. Environmentalists are criticizing a lack of public information about the closed-door talks.

Several models are suggesting that Imelda and Humberto could merge over the North Atlantic, as shown in this HAFS forecast.

Imelda and Humberto are both hurricanes and less than 500 miles apart this morning. No two Atlantic hurricanes have been recorded so close together in the satellite era (since 1966). Imelda is Bermuda bound with a possible sting jet forming as it passes.

What happens when two tropical cyclones get "too" close to each other? It depends! There's often some rotational component of movement around a central point, but the strengths of each cyclone also make a huge difference. This week, #Imelda is set to be pulled into much stronger #Humberto's orbit.

Dr. Sakuhei #Fujiwhara would be elated to see this 6-day forecast. When he wrote his paper on the process we now call the "Fujiwhara Effect" in 1921, numerical modeling and satellite imagery were still decades away. #Imelda #Humberto

The big development since yesterday is forecast models falling in line with sharply turning future Imelda east and avoiding U.S. landfall. Still the U.S. isn't getting off scot-free. The latest details plus all the Category 5 Humberto stats and eye candy.
Forecasts Trend Away from the Carolinas for Soon-to-Be Imelda
Heavy rains still forecast along the immediate Carolina coastal plain ahead of Imelda but landfall scenarios quickly fading

Man, this has been too true for too long. And beyond, "Okay, but get a heat pump" there's also "here's how to get a heat pump" and "here's a great installer."

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

Tropical Depression 9, now in The Bahamas, may dump 10-20" of rain somewhere close to the Southeast U.S. coast as a tropical storm or hurricane early next week. Onshore or offshore? That's one of many big questions in the air right now. Full update:

An exceedingly complex forecast lies ahead for #Humberto and #94L. Of the latter, the Nat'l Hurricane Center warns that "the chances of wind, rainfall, and storm surge impacts for a portion of the southeast U.S. coast are increasing.” Full scoop here:

The federal government has censored the work of dozens of scientists, including work by my lab, on the impacts of climate change on Acadia National Park. Signs have been removed from Cadillac and Great Meadow. They’re also removing signs about the Wabanaki’s sacred connections to Cadillac.

Telltale sign of this odd Atlantic season: The #Azores are on track to experience a hurricane, #Gabrielle, before anyplace in North or Central America or the Caribbean. Meanwhile, Hong Kong and points west are bracing for #Ragasa, still at Cat 4 strength.

As technologies hurl our data into more complexities at dizzying speeds, I’ve come to adore even more the most beautiful score of poetry in our work. Once in a while, we get a call or note, sometimes even a low-tech letter from an adoptee. Friend, me share my appreciation for that with you. 1/n

In a not-so-hard-to-imagine alternate timeline, Gabrielle's still struggling to become the next Atlantic tropical cyclone. Even so, Gabrielle's formation yesterday ended a 20-day active storm drought, the likes of which we haven't seen in at least 86 years. ⬇️
