Waymo robotaxi hailing via the Uber app has ended in Phoenix, Arizona. CNBC reported that the two companies wrapped up the Phoenix pilot and will keep the vehicles operating locally for other uses. Uber said the Phoenix program was intentionally limited, with about 10 dedicated vehicles, and that lessons learned helped it scale quickly in Austin and Atlanta. Waymo said the pilot laid groundwork for global expansion and partnerships.

Data centres around Phoenix, Arizona, could lift nearby temperatures by as much as 4 degrees, according to research. Arizona State University researchers studied 4 sites and compared upwind and downwind temperatures, from a 36-megawatt data centre in Mesa to a 169-megawatt campus in Chandler. They found heat plumes moved with the wind, lifting downwind temperatures by 1.3 to 1.6 degrees on average.
