Artificial intelligence has caused concern for its tremendous consumption of water and power. But scientists are also experimenting with ways that AI can help people and businesses use energy more efficiently and pollute less.

Data centers needed to fuel AI accounted for about 1.5% of the world's electricity consumption last year, and those facilities' energy consumption is predicted to more than double by 2030, according to the International Energy Agency. That increase could lead to burning more fossil fuels such as coal and gas, which release greenhouse gases that contribute to warming temperatures, sea level rise and extreme weather.

Prince Harry and his wife Meghan have joined prominent computer scientists, economists, artists, evangelical Christian leaders and American conservative commentators Steve Bannon and Glenn Beck to call for a ban on AI "superintelligence" that threatens humanity.

The letter, released Wednesday by a politically and geographically diverse group of public figures, is squarely aimed at tech giants like Google, OpenAI and Meta Platforms that are racing each other to build a form of artificial intelligence designed to surpass humans at many tasks.

Israeli settlers descended on Palestinian olive harvesters and activists this week in the Israeli-occupied West Bank, beating them with clubs in an attack Palestinian health officials said sent at least one woman to the hospital with serious injuries.

The attack Sunday in the town of Turmus Ayya, which was captured in videos obtained by The Associated Press, came as Palestinians say settler violence in the region is worsening. The United Nations and rights groups have raised the alarm as harvest season begins and Palestinian farmers are at growing risk while gathering olives.

The Louvre reopened on Wednesday to long lines beneath its landmark Paris glass pyramid, just three days after one of the highest-profile museum thefts of the century stunned the world with its audacity and scale.

The thieves slipped in and out, making off with eight pieces from France's Crown Jewels at the world's most-visited museum — a cultural wound that some compared to the burning of Notre-Dame cathedral in 2019.
