OpenAI not on track to reduce risk of ‘catastrophic’ loss of control, says board member

US government adviser Paul Christiano warns of risks to AI industry as he joins OpenAI’s non-profit foundation

OpenAI is not on track to reduce the risk of “catastrophic” loss of control to an acceptable level, a member of its non-profit board has said, amid spreading public and political concern that super-advanced AIs could one day wipe out humanity.

Paul Christiano, a US government technology adviser, said: “There is a meaningful risk that rapid acceleration in AI capabilities leads to catastrophic and irreversible loss of control in the very near term.”

He added: “I do not think that the AI industry in general, including OpenAI, is currently on track to reduce this risk to an acceptable level.”

Christiano used to run model alignment at OpenAI and made the statement on Wednesday as he joined the board of the San Francisco company’s non-profit foundation.

He will also sit on the foundation’s committee that provides governance over safety and security practices across all of OpenAI, which is developing some of the world’s most advanced models.

This summer, OpenAI admitted that hundreds of its AI agents went rogue during a training exercise, accessed the internet, conspired on message boards and hacked into a third-party website, Hugging Face.

Christiano said that “if OpenAI rises to the occasion we could significantly reduce risk”. His comments came after a senior employee at Anthropic, OpenAI’s major US rival in the race to AI supremacy, claimed on Tuesday there was a greater than 10% chance the technology could “kill all humans” in the next decade.

Evan Hubinger, the alignment science lead at Anthropic, warned that his company did not have a plan to ensure artificial superintelligence (ASI) was aligned, meaning it did no harm. Predictions for when ASI might be reached vary from several years to more than a decade. ASI is often defined as AI that far surpasses human intelligence across a large range of fields.

Fears of AI catastrophe were also ignited by the resignation of Jacob Coxon, a 27-year-old Anthropic researcher who said he also previously worked at OpenAI, claiming “neither company was acting responsibly” and they were “gambling with our lives”.

Coxon said on Wednesday night in an interview with CNN: “Right now there’s no risk of extinction.

“The current models, the worst they can do is maybe hack into something, potentially cause a lot of damages … in infrastructure.” He added they were “not intelligent enough to outsmart us at the level that would lead to extinction”.

But he went on: “What’s just crazy is to look at the rate of progress. There is a very real possibility that in the immediate future … next year, the year after, recursive self-improvement will happen and will enter the phase of Evan’s post, where he argues that there’s a chance we could all die.”

Geoffrey Hinton, the Nobel prize-winning computer scientist known as one of the “godfathers of AI”, was asked on Wednesday for his view of Hubinger’s claim and told BBC Newsnight: “Nobody knows how to estimate it; a 10% chance seems not an unreasonable estimate.”

Christiano’s prognosis about the likelihood of the AI industry reducing risk came as concerns about the most extreme risks from super-powerful AIs, long discussed in Silicon Valley, broke out into the mainstream this week.

Politicians on both sides of the Atlantic, from Ted Cruz and Bernie Sanders in the US to the MP Darren Jones in the UK, have called for government action and the UK prime minister, Andy Burnham, told parliament on Wednesday that “AI poses risks to our national security, but it also could be the source of solutions to keeping us safer”.

Meanwhile, Anthropic has admitted a new incident in which a version of its Claude model in training broke into third parties after its task could not be aborted. It said the incident happened in January and would be included in an independent investigation of a total of four incidents to be carried out by the Berkeley-based AI safety organisation METR.

Overall, it said the models were showing two forms of misalignment: biased reasoning, in which models selectively interpret evidence in ways that favour justifying their actions, and “recklessness, in which models have a propensity to keep trying to solve their task, even when this could lead to harm”.

Anthropic said it was especially concerned about misalignment it found in the behaviour of Claude Mythos 5, which it said “behaved recklessly” by going online and uploading malicious code to a public software repository, PyPI. This was a process that involved the AI agent trying to find cryptocurrency so it could pay for a phone number that would allow it to register an email address needed to access PyPI. When this failed, it found a free email provider and got in. Fifteen systems then downloaded the malicious code, which meant they leaked credentials that allowed Mythos to access a real security vendor’s database.

The company’s assessment of the incidents said: “This remains unsettled science – it is critical that alignment and security mature faster than capabilities advance, which is one reason we support a coordinated, verifiable approach to pacing frontier AI development.”

Climate ‘feedback loops’ could worsen global warming by 30%, study finds

Climate ‘feedback loops’ could worsen global warming by 30%, study finds

Emissions of planet-heating methane and CO2 from natural sources are worsening the climate crisis, paper says

Rising global temperatures caused by the burning of fossil fuels are transforming the world’s forests, wetlands and tundra to the point they are releasing emissions that could further worsen global heating by as much as 30%, a new study has found.

As the world heats up, permafrost in the high latitudes is thawing, fiercer wildfires are burning in drying forests and wetlands and lakes are warming. All of these changes are themselves causing the release of planet-heating methane and carbon dioxide locked in trees and soils, therefore worsening the climate crisis, the paper states.

While scientists have long known of these “feedback loops” that amplify the impact of direct pollution from burning coal, oil and gas, the emissions from natural sources are largely unaccounted for in climate projections.

This additional heating is however significant, researchers found, with emissions from natural sources set to amplify global heating by 20% to 30% by the end of this century. This would add an estimated 0.2C to 0.4C to the global average temperature by this time, depending on the overall action taken by countries to combat the climate crisis.

Even small fractions of temperature change across the global climate can greatly change the risk of severe and deadly heatwaves, floods, drought and other impacts.

The United Nations last week conceded the international pact to constraint the global temperature rise to 1.5C above pre-industrial levels will be breached in the next few years, causing climate impacts such as this summer’s record heatwaves and wildfires to “strike faster, hit harder and last longer.”

Yet the increase in the world’s fever will likely be even larger than most projections currently account for, the new research warns, as they do not factor in the methane and CO2 that will spew from permafrost, wetlands, freshwaters and wildfires – the four areas the paper analyzed.

“This hidden multiplier is missing from the models guiding climate policy, so those models are likely underestimating how much warming is coming – and overestimating how much carbon we can still afford to emit,” said Sam Abernethy, a scientist at Spark Climate Solutions Research who led the research, published in Environmental Research Letters.

The disruption of the world’s carbon cycles is now being seen in “real time”, said Rob Jackson, a Stanford University scientist and study co-author. “The results are a wake-up call, and it’s imperative that they be included in the next generation of climate policies,” he added. “Failure to do so will make meeting the world’s climate goals less and less likely.”

There has been long-standing concern that should global heating melt enough of the Greenland and Antarctic ice sheets, thaw enough permafrost, warp crucial ocean currents and turn the Amazon rainforest into a savannah, the world will career past a series of catastrophic tipping points where the climate system spins wildly outside any sort of restraining human influence.

The planet is getting closer to such a “point of no return” where this runaway global heating becomes reality, a separate study earlier this year warned.

This latest paper makes clear that action by countries to cut fossil fuel pollution will still lessen the amount of additional emissions that come from landscapes. Under the most optimistic climate scenario where emissions are cut quickly, natural sources will add 0.2C of warming, the paper found. Under a worse case higher emissions scenario, 0.4C will likely be added.

Current policies put in place by governments are likely to see the global temperature rise to 2.6C above pre-industrial times, according to Climate Action Tracker. This will likely cause severe disruption and hardship to billions of people through sea level rise, crop losses and other consequences.

“One of the most troubling aspects of climate change is that warming can trigger natural processes that cause still more warming,” said Bill Ripple, an ecologist at Oregon State University who helped author the research earlier this year on runaway heating. He was not involved in the new paper, which he called “important”.

“This does not mean that a Hothouse Earth trajectory is inevitable, but it provides another warning about the possibility of reinforcing feedbacks that can amplify the warming humans initiate,” he said.

“The paper also reminds us why every fraction of a degree matters. The more we warm the planet, the more we risk activating natural processes that add still more greenhouse gases to the atmosphere. This makes rapid reductions in fossil fuel emissions even more urgent.”
