Drought in California. Extreme heat in Australia. An unusually cold spring in the U.K.
These were some of the notable weather events of last year.
Monday the National Oceanic and Atmospheric Administration - or NOAA - released a massive report looking at 16 such events.
Nine of them were shown to be linked to human-caused climate change.
To tell more about the report is Southern California Public Radio's Sanden Totten.
