At UK's AI Summit developers and govts agree on testing to help manage risks

Leading AI developers agreed to work with governments to test new frontier models before they are released to help manage the risks of the rapidly developing technology, in a "landmark achievement" concluding the UK's artificial intelligence summit.

Some tech and political leaders have warned that AI poses huge risks if not controlled, ranging from eroding consumer privacy to danger to humans and causing a global catastrophe, and these concerns have sparked a race by governments and institutions to design safeguards and regulation.

At an inaugural AI Safety Summit at Bletchley Park, home of Britain's World War Two codebreakers, political leaders from the United States, European Union and China agreed on Wednesday to share a common approach to identifying risks and ways to mitigate them.

British Prime Minister Rishi Sunak said that declaration, the action on testing and a pledge to set up an international panel on risk would "tip the balance in favour of humanity".

He said the United States, EU and other "like-minded" countries had reached a "landmark agreement" with select companies working at AI's cutting edge on the principle that models should be rigorously assessed before and after they are deployed.

How will future climate change affect the world?

Scientists say limiting temperature rise to 1.5C is crucial to avoid the most dangerous impacts of climate change - although these increase with every extra increment of warming.

The 1.5C warming limit was partly designed to avoid crossing so-called "tipping points".

These are thresholds beyond which changes could accelerate and become irreversible in different parts of the Earth's climate system, such as the collapse of the Greenland Ice Sheet.

But it's not clear precisely where these thresholds sit. Some may have already been crossed; some may be further away than first thought.
