UN Says Breaching 1.5C Warming Limit Is 'Imminent and Unavoidable'

For the first time, the UN has declared that exceeding the Paris Agreement's 1.5C warming limit is "imminent and unavoidable." "We are now saying this window has closed, but we can open it again by making the overshoot as brief as possible," UN Environment Program Executive Director Inger Andersen said on a call with reporters. "This is about how to find a way back as shortly and as quickly as possible with as limited an overshoot as possible." CNN reports: Past reports have examined the distance between countries' emissions reduction commitments and what it would take to limit global warming to 1.5 C above preindustrial levels. However, this year's report redefines the gap. Instead, it examines new emissions overshoot scenarios, and what it would take to limit peak warming to just 1.7 to 1.8 degrees C before bringing temperatures back down to 1.5 C through emissions cuts and the use of carbon removal technologies. The report makes clear that every additional fraction of a degree of warming above 1.5 C "raises the risk of irreversible changes including in ice sheets, permafrost carbon, ocean circulation, and coral systems, along with devastating human impacts." Each added fraction of a degree of warming can have an "immense" impact "as measured in terms of damage, cost and loss of lives," said climate scientist Michael Mann of the University of Pennsylvania. Mann was not involved in producing the UNEP report. According to the UNEP, which is based in Nairobi, the lowest overshoot scenario would keep peak warming to between 1.7 and 1.8 degrees C and return global average temperatures to at or below 1.5 C by 2100. However, to follow such a pathway, global greenhouse gas emissions would need to be slashed by far more than anything currently on the table at the upcoming COP31 talks. This would require an 18% cut by 2030, 45% by 2035, and 69% by 2040, relative to 2025 levels. Meeting this lowest-possible overshoot scenario would require a tripling of renewable electricity capacity by 2035, and dramatic cuts to fossil fuels, including the phaseout of coal by 2040, the report states. In addition, there would need to be a major scaling up of carbon removal technologies, which so far have not been proven to work at such a large scale. In stark contrast to these figures, the fulfillment of existing emissions reduction pledges would only yield a 5-to-8% emissions cut by 2030 and an 11-to-15% reduction by 2035, the report found. This would be associated with a peak warming of about 2.6 degrees C. If countries simply follow their current policies, then warming could reach a peak of about 2.8 C. That estimate has increased since last year, in part because of the withdrawal of the United States from the Paris Agreement and retraction of its emissions reduction commitments, the report states. Even the scenario that assumes countries meet their existing reduction commitments, and nations with net-zero pledges succeed in fulfilling them, still brings warming to a peak of 2.1 C.

Unvetted AI Agents Are Accessing US Bank Accounts

An anonymous reader quotes a report from Axios: Major U.S. banks are detecting unauthorized third-party AI agents operating inside customer accounts, with some agents attempting to take actions that appear to be independent of user instructions, sources tell Axios. The difficulty in distinguishing between a human and an unauthorized bot is forcing banks to block the technology and rapidly rewrite their terms of service. [...] This presents significant security risks: banking executives fear the steps agents with login access might take, especially if a user has granted purchase authority or the ability to shift funds. In other instances, some banks have tracked activity when agents -- programmed to fulfill requests or complete tasks on a user's behalf -- contact call centers or appear to take actions independent of user instructions, the people said. Bank executives described the situation as horrifying, with one official saying the industry has grave concerns about agents gaining access to customer accounts and taking steps that could impact user finances. The concerns are at the root of the decision by several banks to restrict third-party AI agent access, the people said. Morgan Stanley has begun blocking third-party agents from accessing its platforms, sources familiar with the decision said. JPMorgan, Bank of America and Citi are also restricting agents. [...] Many banks are broadly not able to parse whether agent account activity is user-directed, sources said. [...] On one hand, banks are best positioned to respond to the threats and opportunities of AI given their cash on hand and experience as critical infrastructure. But money isn't necessarily enough to solve this problem, one source said, because of how quickly the technology is developing and revealing new weaknesses in real time. Banks are investing in preventing worst-case scenarios, but they are also preparing for when those could happen, including with "day after" scenario planning that would allow them to quickly secure or restore customer access, sources said.

“I can’t believe PowerShell is actually good”

Earlier this year, I needed to learn PowerShell scripting for one Windows-related project, and I have tried it out a few more times on Mac. It has quickly become one of my favorite tools for automation and scripting-taking on jobs that I would have otherwise tried to do with Node.js, Shortcuts, macOS Automator, or heaven forbid, Bash scripts. I get it now. PowerShell is great, even if you don't use it as your shell, and even if you're on Mac or Linux. ↫ Corbin Davenport I don't use the shell often enough on any of my main machines to have much of an idea about the strenghths and weaknesses of PowerShell compared to more traditional shells, but this is definitely not the first time I've heard a lot of praise for it from people otherwise knee-deep in the UNIX and traditional shell world. There really must be something to this, and since PowerShell is also available on Linux and macOS, it's pretty straightforward to give it a go without having to deal with Windows.

To Make Way For Data Centers, Google Will Pay Others to Use Less Power

Google is funding one of the nation's largest "virtual power plants," paying homes and businesses indirectly to reduce electricity consumption during periods of peak demand so more grid capacity can be available for data centers. Under its expanded deal with Voltus, the program could provide up to 1,070 megawatts in the Mid-Atlantic PJM grid -- roughly the output of a large nuclear reactor. The New York Times reports: That electricity won't come from new power plants. Instead, Voltus will sign up homes and businesses and give them financial incentives to curb their usage when local power demand is high or the grid is strained. Many of these reductions could occur automatically, such as through smart thermostats that dial back air-conditioning during peak summer hours or batteries that can provide temporary on-site power. Each of these tweaks frees up only a small amount of power on its own. But by aggregating them across thousands of businesses and homes, Voltus says it can reliably provide lots of extra capacity when it's most needed, and do so within a few years. While tech companies will likely ultimately need to build traditional power plants if they want to keep building large data centers, this approach could be a faster, cheaper and less-polluting option in the interim. "We really see virtual power plants as a critical short-term solution," said Ellen Zuckerman, head of energy market development for North and South America at Google. "It's a way to invest in our communities, really double down on our clean energy ambition, but also meet capacity at speed and scale."

Garmin revamps and opens up Connect developer API program

Earlier this year, Garmin closed its Connect API developer program because it was being flooded with "AI"-generated applications to the point it couldn't handle them anymore. What made it worse was that half of the applications were never actually used, not even once. It also didn't help that Garmin treated every single application to the program the same way, whether it was from a hobbyist just wanting access to their own data, to a massive corporation developing a popular service used by god knows how many people. Today, the company has relaunched the program, and it's been considerably overhauled. While hobbyist use of the API is going to be free - which is way better than it was before - once you hit a thousand users, you're going to have to start paying. Still, Garmin's shift here towards charging for API access will set a dangerous precedent for the industry. Especially for a company that bills itself as a (or the?) premium sports hardware provider. On the flip side, there's simply no ignoring the flood of mostly AI apps that take up resources at Garmin and elsewhere to support. Heck, my inbox is flooded with these apps daily requesting reviews. It sounds like when Garmin shut off access to the API last spring, they were seeing inbound API requests at a daily scale that they'd previously only seen over a period of weeks. Simply put, there's no good answer. ↫ Ray Maker at DC Rainmaker The excesses of the easy availability of "AI" code generation impacts the entire industry. At least one good thing has come out of this: hobbyists can now access the Connect API developer program much easier than before.

Examining the macOS gcc binary

If you've ever written C (or c++) on a mac, you'll know that the so-called gcc is just clang in disguise. Most people (fairly) assume that this is just an alias, but this is not true! It's a binary! Now, what is this binary? I naively assumed that it would just be shelling out to clang but it turns out the answer is more interesting than that. ↫ juliethefoxcoon It's all smoke and mirrors.

This meant binaries to read/write individual file types, better error messages, extensive specifications and of course exports to common dataformats like JSON. The thing is, although some of us already had experience with low-level dataframe parsing, …

On scripts and hooks

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target.
