A new study from Stanford University says that climate change driven by humans is behind the drought in California, which is affecting 98 percent of the state.
The two main weather conditions that lead to drought — higher than average temperatures and tiny amounts of rain and snow — are occurring at the same time because of climate change, the study shows. Researchers also found that the worst droughts in the state's history happened when it was dry and warm, and global warming is increasing the chance that those weather patterns will take place at the same time, USA Today reports. The study's leader, Noah Diffenbaugh, said having dry years that are also warm would not happen without human influence, like burning fossil fuels.
