In the last few years many in north america we were introduced to a new phrase 'polar vortex' which has been unstable and resulted in colder winter storms, yet as I understand a milder winter overall. Read more here on it's relation to climate change http://www.ucsusa.org/global_warming/science_and_impacts/science/cold-snow-climate-change.html http://www.ucsusa.org/global_warming/science_and_impacts/sci... Regardless you are getting hung up on 'colder', the key is more extreme weather. To that point the IPCC does mention more extreme storms, if you want a reference googling that yourself will bring up plenty. I'll assume you live in sunny California and extreme weather to you means rainstorms not crazy ass cold polar vortex dumps of snow and ice.
