An intense heat wave moved up the West Coast and brought triple-digit heat from Phoenix to San Francisco. Some in the media pinned scorching temperatures on global warming, but is it really to blame?

Record-high temperatures were forecast along the west coast Tuesday, according to the National Weather Service. San Francisco, Sacramento and Phoenix saw temperatures over 100 degrees Fahrenheit, and the Pacific Northwest was well into the 90s.

Downtown San Francisco saw its hottest three-day stretch in meteorological summer on record.

“It has already started to cool down in California — and in Seattle,” Cliff Mass, a climate scientist at the University of Washington, told The Daily Caller News Foundation via email.

“This is not climate change, but a temporary ridging in the eastern Pacific and, ironically, colder than normal temperatures over the Inter-mountain West,” Mass said.

Cooling is already underway, as Mass noted, though hot temperatures are forecast for Thursday. Some parts of the Bay Area cooled as much as 27 degrees from Tuesday’s highs.
