Climate folks: Who are the experts on how undersea cable data is used to measure North Atlantic salinity and currents, and detect potential AMOC weakening?

Housing and rent prices collapsed in Austin and people still pretend building housing isn’t the solution to affordability.
Nick Gerli@nickgerli1
It's actually never been cheaper to rent in Austin, TX. The Rent/Income ratio across the metro has dropped to 18.3% - the lowest on record (going back at least 20 years). Landlords are aggressively cutting rents at a time when incomes in Austin keep rising. The typical rent is down to $1,565/month. While the median income is up to $100k. Making Austin the cheapest city to rent relative to income.

This mini-forest, like many across the globe, follows the Miyawaki Method of densely planting specific native species to jump-start forest development.
“Since they’re planted close together, as they grow, they branch out, and they start to touch each other and form a canopy,” says Hannah Lewis, author of the book “Mini-Forest Revolution– Using the Miyawaki Method to Rapidly Rewild the World”.
“And so then they’re shading out weeds and they’re creating that microclimate that holds humidity inside, so you no longer need to water or weed after two or three years.”

North American bird populations are not only declining, but they’re also shrinking faster with each passing year—particularly in regions shaped by intensive agriculture, according to a new study in Science. scim.ag/4clAUaN

Since 2014, Sydney has carved out 79.5 miles of tunnels underneath the city to create a brand-new, fully automated metro system. North American leaders need to stop thinking so small.

'At this point, 'building housing reduces rent' is as close to a scientific law of the housing market as we’re likely to find' - @Noahpinion

Keeping the buildings the same does not preserve a community's character.
When you make it illegal to build new housing at the high end of the market, rich people just buy up existing less-expensive homes and renovate them into luxury houses.

Ultra-rich buyers are consolidating New York townhouse apartments into giant single-family homes. Some are buying two, even three adjacent townhouses to build a franken-home. The Manhattan mega-mansion is the status symbol for the second Gilded Age: bloomberg.com/graphics/2026-…

The first half of the 2020s were a natural experiment in housing policy. In response to a run up in prices, major cities either (a) built a ton of housing or (b) adopted more IZ/RC/etc. The former are mostly out of the crisis, while the latter are still in the thick of it.

Austin TX is now back to pre-pandemic apartment rents. Down 21% from peak in summer of 2022. $1,636/month --> $1,288/month (I'm now even seeing 2BRs in some apartments at sub-$1,000) This rental correction is due to a sharp drop in migration/demand, combined with a surge of new apartment development. At this point, Austin has its cheapest rents on record relative to income.

The busiest sections of I-5 in Los Angeles and I-75 in Atlanta, the two busiest highways in the country, move fewer people than the 4/5/6 subway lines do alone.

Seeing this as my train from NYC to Richmond took 3ish hours to DC then another 4 hours from DC to Richmond makes me think we shouldn’t need this level of oversight to make good things happen in this country

To clear California High-Speed Rail for use on EXISTING train tracks between San Jose and San Francisco alone, the environmental review process produced a final report of 8,204 pages (456 hours of reading) and took almost 14 years to complete. We need reform.

Another academic research paper showing that minimum lot sizes (often used to block higher-density housing) drive up prices and rents.
If you care about home/rental affordability, focus on the science. The most compassionate thing to do is focus on proven solutions.

Build and fund the trains, people use them. Transportation policies that expand travel options are a great way to reduce traffic in and out of our cities

Good news: Our @Amtrak Mardi Gras Service has been selling out on some weekends, especially when the New Orleans @Saints have home games. We are planning to add an additional 60 seats (one railcar) over some of these periods. This will include the coming weekend, three weekends in October, a weekend in November and two weekends in December.

Ohio, with an economy the size of Switzerland, runs just 48 trains a week. Switzerland runs 77,000.
Over the next four years, Ohio will spend $2.45 million on trains, against $6.7 billion for roads and highways.
Meanwhile, here’s what became of Dayton’s train station:

Anti density protestors seeking refuge in the shade is a hilarious irony.

The anti-SB 79 "protest" today looked less like a rally and more like someone forgot to cancel a picnic.

Turns out it’s worse than it sounds because they’re only ticketing during drop off and pick up hours

over 250 speeders a day going at least 11 mph over the limit in a school zone. almost like the design of the roads is bad and encourages speeding

The NIMBY three step: “I participated in the public process and did not get my way” becomes “I was left out of the decision making process” and then turns into “I deserve the power to overturn the result of the public process and impose my will on the majority by lawsuit.”
