Parts of California survived a record-breaking three-day heatwave last week with a recorded high of 96 degrees in Anaheim. While the drastic change in temperature was shocking, it's surely not the worst the state has ever seen. In fact, California holds the world record for the highest temperature ever recorded. Way back in 1913, Death Valley's Greenland Ranch hit 134 degrees.

Stacker compiled a list of California's most extreme temperatures throughout history. The website consulted 2021 data from the NOAA's State Climate Extremes Committee (SCEC) to track down the hottest and coldest temperatures ever recorded in every state. Here are California's most extreme:
