This is an urgent reminder of how “real” the climate crisis is, Newsom said. He warned of bottlenecks in the energy supply and called on the residents of the most populous US state to save electricity, for example not to set their air conditioning to the lowest temperatures.

The National Weather Service expected temperatures close to record levels in many places. Temperatures of around 51 degrees Celsius have been forecast for the weekend in California’s Death Valley, which is known for extreme heat.
