UN: Fossil fuels should be terminaated 86 years from now

World must stop feeling the burn by shifting to low carbon sources, claims IPCC


The latest UN Intergovernmental Panel on Climate Change (IPCC) report alarmingly warned today that it was vital for the world to phase out fossil fuels by 2100.

The committee claimed that cutting greenhouse gas emissions by between 40 per cent and 70 per cent by 2050, and to near or below zero emissions in 2100 "would likely keep warming <2°C."

Its chair Rajendra Pachauri warned during a press conference in Copenhagen, Denmark on Sunday morning, according to official tweets from the IPCC, that "climate change will leave no part of the world untouched."

He added that the "costs of inaction" were "much higher than the costs of action. Inaction would create increasing risks to economic growth."

IPCC chair of Working Group I Thomas Stocker said: “Our assessment finds that the atmosphere and oceans have warmed, the amount of snow and ice has diminished, sea level has risen and the concentration of carbon dioxide has increased to a level unprecedented in at least the last 800,000 years.”

The IPCC AR5 Synthesis report (PDF) claimed that the global temperature rise of >4°C combined with an increase in demand for food would "pose large risks to global food security."

Climate experts have been locked in talks with government bods for the past week.

"The science community has now spoken and is passing the baton to policymakers," said Pachauri.

On the projected changes in the climate system, the report authors said:

Surface temperature is projected to rise over the 21st Century under all assessed emission scenarios. It is very likely that heat waves will occur more often and last longer, and that extreme precipitation events will become more intense and frequent in many regions. The ocean will continue to warm and acidify, and global mean sea level to rise.

On climate change beyond 2100, it warned:

Many aspects of climate change and associated impacts will continue for centuries, even if anthropogenic emissions of greenhouse gases are stopped. The risks of abrupt or irreversible changes increase as the magnitude of the warming increases.

The IPCC added:

There are multiple mitigation pathways that are likely [panel's emphasis] to limit warming to below 2°C relative to pre-industrial levels. These pathways would require substantial emissions reductions over the next few decades and near zero emissions of CO2 and other long-lived GHGs by the end of the century.

Implementing such reductions poses substantial technological, economic, social, and institutional challenges, which increase with delays in additional mitigation and if key technologies are not available. Limiting warming to lower or higher levels involves similar challenges, but on different timescales.

  • It's 2022 and there are still malware-laden PDFs in emails exploiting bugs from 2017
    Crafty file names, encrypted malicious code, Office flaws – ah, it's like the Before Times

    HP's cybersecurity folks have uncovered an email campaign that ticks all the boxes: messages with a PDF attached that embeds a Word document that upon opening infects the victim's Windows PC with malware by exploiting a four-year-old code-execution vulnerability in Microsoft Office.

    Booby-trapping a PDF with a malicious Word document goes against the norm of the past 10 years, according to the HP Wolf Security researchers. For a decade, miscreants have preferred Office file formats, such as Word and Excel, to deliver malicious code rather than PDFs, as users are more used to getting and opening .docx and .xlsx files. About 45 percent of malware stopped by HP's threat intelligence team in the first quarter of the year leveraged Office formats.

    "The reasons are clear: users are familiar with these file types, the applications used to open them are ubiquitous, and they are suited to social engineering lures," Patrick Schläpfer, malware analyst at HP, explained in a write-up, adding that in this latest campaign, "the malware arrived in a PDF document – a format attackers less commonly use to infect PCs."

  • New audio server Pipewire coming to next version of Ubuntu
    What does that mean? Better latency and a replacement for PulseAudio

    The next release of Ubuntu, version 22.10 and codenamed Kinetic Kudu, will switch audio servers to the relatively new PipeWire.

    Don't panic. As J M Barrie said: "All of this has happened before, and it will all happen again." Fedora switched to PipeWire in version 34, over a year ago now. Users who aren't pro-level creators or editors of sound and music on Ubuntu may not notice the planned change.

    Currently, most editions of Ubuntu use the PulseAudio server, which it adopted in version 8.04 Hardy Heron, the company's second LTS release. (The Ubuntu Studio edition uses JACK instead.) Fedora 8 also switched to PulseAudio. Before PulseAudio became the standard, many distros used ESD, the Enlightened Sound Daemon, which came out of the Enlightenment project, best known for its desktop.

  • VMware claims 'bare-metal' performance on virtualized GPUs
    Is... is that why Broadcom wants to buy it?

    The future of high-performance computing will be virtualized, VMware's Uday Kurkure has told The Register.

    Kurkure, the lead engineer for VMware's performance engineering team, has spent the past five years working on ways to virtualize machine-learning workloads running on accelerators. Earlier this month his team reported "near or better than bare-metal performance" for Bidirectional Encoder Representations from Transformers (BERT) and Mask R-CNN — two popular machine-learning workloads — running on virtualized GPUs (vGPU) connected using Nvidia's NVLink interconnect.

    NVLink enables compute and memory resources to be shared across up to four GPUs over a high-bandwidth mesh fabric operating at 6.25GB/s per lane compared to PCIe 4.0's 2.5GB/s. The interconnect enabled Kurkure's team to pool 160GB of GPU memory from the Dell PowerEdge system's four 40GB Nvidia A100 SXM GPUs.

  • Nvidia promises annual updates across CPU, GPU, and DPU lines
    Arm one year, x86 the next, and always faster than a certain chip shop that still can't ship even one standalone GPU

    Computex Nvidia's push deeper into enterprise computing will see its practice of introducing a new GPU architecture every two years brought to its CPUs and data processing units (DPUs, aka SmartNICs).

    Speaking on the company's pre-recorded keynote released to coincide with the Computex exhibition in Taiwan this week, senior vice president for hardware engineering Brian Kelleher spoke of the company's "reputation for unmatched execution on silicon." That's language that needs to be considered in the context of Intel, an Nvidia rival, again delaying a planned entry to the discrete GPU market.

    "We will extend our execution excellence and give each of our chip architectures a two-year rhythm," Kelleher added.

  • Amazon puts 'creepy' AI cameras in UK delivery vans
    Big Bezos is watching you

    Amazon is reportedly installing AI-powered cameras in delivery vans to keep tabs on its drivers in the UK.

    The technology was first deployed, with numerous errors that reportedly denied drivers' bonuses after malfunctions, in the US. Last year, the internet giant produced a corporate video detailing how the cameras monitor drivers' driving behavior for safety reasons. The same system is now apparently being rolled out to vehicles in the UK. 

    Multiple camera lenses are placed under the front mirror. One is directed at the person behind the wheel, one is facing the road, and two are located on either side to provide a wider view. The cameras are monitored by software built by Netradyne, a computer-vision startup focused on driver safety. This code uses machine-learning algorithms to figure out what's going on in and around the vehicle.
