California hit with two heat waves in less than a month. Here's why it matters.

Historic heat records fell in California earlier this month. Yet, two weeks later, another mass of warm air has returned to the southern part of the state, heating the region for days.

The second heat wave of July will last from Monday through Thursday, said the National Weather Service. While this heat won’t be quite as severe as the last, it’ll still bring “record and near-record high temperatures” to different areas of California. 

As average temperatures around the globe continue their accelerated rise, extreme heat events like these are becoming more and more frequent.
