Earth is warming. Why is California having a record-breaking winter?

In the Bay Area, the past three months have included historic rains, record-breaking low temperatures, and even snow in places like the Berkeley hills and North Bay highlands. In the Sierra Nevada, storms and frigid temperatures have produced so much snow that this year’s snowpack could become the largest ever recorded for the state, following upcoming storms.

A Pineapple Express — an atmospheric river ferrying moisture from waters off the coast of Hawaii — brought even more wet weather to California on Thursday, prompting Gov. Gavin Newsom to proclaim a state of emergency that includes San Francisco, San Mateo, Santa Clara and Napa counties. Areas at high risk for excessive rains and flash floods are under yet another round of evacuation orders.
