Can the climate survive the insatiable energy demands of the AI arms race?

New computing infrastructure means big tech is likely to miss emissions targets but they can't afford to get left behind in a winner takes all market

The artificial intelligence boom has driven big tech share prices to fresh highs, but at the cost of the sector's climate aspirations.

Google admitted on Tuesday that the technology is threatening its environmental targets after revealing that datacentres, a key piece of AI infrastructure, had helped increase its greenhouse gas emissions by 48% since 2019.
