An anonymous reader writes: Using realistic ecological modeling, scientists led by Western Sydney University’s Jürgen Knauer found that the globe’s vegetation could actually be taking on about 20% more of the CO2 humans have pumped into the atmosphere and will continue to do so through to the end of the century.

“What we found is that a well-established climate model that is used to feed into global climate assessments by the likes of the IPCC (Intergovernmental Panel on Climate Change) predicts stronger and sustained carbon uptake until the end of the 21st century when extended to account for the impact of some critical physiological processes that govern how plants conduct photosynthesis,” said Knauer.

Mathematical models of ecological systems are used to understand complex ecological processes and in turn attempt to predict how the real ecosystems they’re based on will change. The researchers found that the more complex their modeling, the more surprising the results – in the environment’s favor.

Current models, the team adds, are not that complex so likely underestimate future CO2 uptake by vegetation… [T]he modeling makes a strong case for the value of greening projects and their importance in comprehensive approaches to tackling global warming.

Back in 2021 Hurricane Ida knocked out power lines in New Orleans, leaving parts of the city in darkness for 10 days.

So a coalition of community-based organizations (including some churches) decided to build “solar-powered disaster response hubs that could transform the city’s approach to resilience,” reports the Guardian. So far there’s seven, but the group “has ambitions to build dozens more.”

On a bright, balmy autumn morning a couple of weeks ago [61-year-old pastor Antoine] Barriere climbed a long, steep ladder to show me the 460 solar panels that now cover a third or so of his church’s flat roof. The solar panels were generating more than enough energy to power Household of Faith, a non-denominational megachurch with 4,000 mostly Black parishioners in New Orleans East. Downstairs, a cabinet was stacked with backup batteries that were fully charged in case of a power outage — a frequent occurrence thanks to the low-lying city’s vulnerability to hurricanes, thunderstorms, high winds, extreme heat and flooding. In a worst-case scenario — no sun, thundery dark skies and power outage — the backup batteries could power essential appliances for a couple of days including the water heater, five commercial fridge freezers storing perishables for the weekly food pantry, and air conditioning for the vast main hall which could be converted into a dormitory-style shelter.

But on this brilliant cloudless morning, most of the solar-generated energy was going into the city’s electric grid. New Orleans’ one-for-one net metering scheme allows the church to offset its excess clean energy against the utility’s dirty energy, and this should become a net zero facility within 12 months… The idea is that each community lighthouse should be an institution locals already know and trust — such as a place of worship, health clinic or community centre — that can be converted into a resilience hub where people can converge during a power outage to get cool, recharge phones, have a meal, connect to a medical device or store medication that requires refrigeration such as insulin. In addition, community lighthouses will be able to keep the services running that people rely on such as the food pantry and religious sermons, while also adding capacity to the city’s wider emergency-response efforts as a distribution hub, shelter and possibly even house a makeshift clinic.

Long-time Slashdot reader nmb3000 writes: The Electronic Frontier Foundation has published a new white paper, Privacy First: A Better Way to Address Online Harms , to propose an alternative to the “often ill-conceived, bills written by state, federal, and international regulators to tackle a broad set of digital topics ranging from child safety to artificial intelligence.” According to the EFF, “these scattershot proposals to correct online harm are often based on censorship and news cycles. Instead of this chaotic approach that rarely leads to the passage of good laws, we propose another solution.”

The EFF writes:

What would this comprehensive privacy law look like? We believe it must include these components:

No online behavioral ads.Data minimization.Opt-in consent.User rights to access, port, correct, and delete information.No preemption of state laws.Strong enforcement with a private right to action.No pay-for-privacy schemes.No deceptive design.

A strong comprehensive data privacy law promotes privacy, free expression, and security. It can also help protect children, support journalism, protect access to health care, foster digital justice, limit private data collection to train generative AI, limit foreign government surveillance, and strengthen competition. These are all issues on which lawmakers are actively pushing legislation—both good and bad.

It’s “the conference about the joy of Emacs and Emacs Lisp.” Started in 2013, the volunteer-run EmacsConf accepted 44 talks for this year — and Day Two has just started streaming online now.
Sunday kicks off with a talk counting on how the “hypertextual information manager” GNU Hyperbole can improve your Emacs productivity. (Click here for a list of all of Sunday’s talks.) Or hang out in the #emacsconf channel on irc.libera.chat.

The Free Software Foundation provided fiscal sponsorship for this year’s event, noting that “The conference has grown rapidly in the last few years” and “welcomes speakers of all backgrounds and all levels of experience from across the world.
“EmacsConf is rooted in the active, passionate community surrounding GNU Emacs, and like Emacs itself, it is committed to user freedom. It is organized and run using an entirely free software stack.”

100 miles south of the Canadian border, the tiny town of Bemidji, Minnesota “has been bombarded by a sudden onslaught of Amazon packages” since early November, reports the Washington Post, “and local postal workers say they have been ordered to deliver those packages first.”

A spokesperson for the U.S. Postal Service tells the Post that’s not true, and that their service “does not prioritize the delivery of packages from Amazon or other customers.”
But whatever’s going on, the Post reports that “The result has been chaos…”

Mail is getting backed up, sometimes for days, leaving local residents waiting for checks, credit card statements, health insurance documents and tax rebates. Routes meant to take eight or nine hours are stretching to 10 or 12. At least five carriers have quit, and the post office has banned scheduled sick days for the rest of the year, carriers say… Dennis Nelson, a veteran mail carrier, said he got so frustrated watching multiple co-workers “breaking down and crying” that he staged a symbolic strike earlier this month outside the post office where he has worked for more than 20 years…

Bemidji is not the only place where postal workers say they have been overwhelmed by packages from Amazon… Carriers and local officials say mail service has been disrupted in rural communities from Portland, Maine, to Washington state’s San Juan Islands.

The situation stems from a crisis at the Postal Service, which has lost $6.5 billion in the past year. The post office has had a contract with Amazon since 2013, when it started delivering packages on Sundays. But in recent years, that business has exploded as Amazon has increasingly come to rely on postal carriers to make “last-mile” deliveries in harder-to-reach rural locations. The Postal Service considers the contract proprietary and has declined to disclose its terms. But U.S. Postmaster General Louis DeJoy has said publicly that “increasing package volume” — not just from Amazon, but from FedEx and UPS as well — is key to the mail service’s financial future. In a Nov. 14 speech to the Postal Service Board of Governors, DeJoy said he wants the post office to become the “preferred delivery provider in the nation….”

In bigger cities, Amazon has its own distribution network, which takes some of the pressure off the post office. But in rural areas, where carriers drive miles of lonely routes in their personal vehicles, the arrangement has caused problems. In the mountains of Colorado, biologists in Crested Butte are struggling with the delay of time-sensitive samples, the Denver Post reported in September, while mail carriers in Carbondale say they are overwhelmed by Amazon packages. Other Minnesota towns including Brainerd and La Porte have been hit hard by Amazon in the past, carriers said…

Partenheimer defended the post office’s record in an email, while conceding “much work remains to be done….”

An Amazon spokesperson told the Post “We work directly with the USPS to balance our delivery needs with their available capacity,” and “we’ll continue to collaborate on package volume each week and adjust as needed.”
