how do you get climate if you aren't collecting data? That historical.and if current weather matches historical, then climate has changed agreed?It's Christmas morning. Time to go open gifts now. I blew the whole global warming thing out of the water with an exact climatological analysis of this warm winter.
Actually all you did was show how the shifting PDO is effecting local weather. You missed entirely that climate and weather are two different things.
While weather might be doing X if you average all that weather together, you get climate.
Define historical ?
The weather can fluctuate all it wants, as long as it the average of all weather lands within certain parameters its irrelevant. However once that average falls outside of those so called historical norms then it becomes a problem.
Within the climate history are events of Rapid Global Climate Change and they are typically associated with mass extinctions. The KT boundary extinction or the high permian extinction. Even the snowball earth event of say 650 million years ago is accompanied with a major alteration in the atmospheric chemistry.
Todays event however is unique in that for the first time we see the signature of fossil CO2 from the burning of fossil fuels in virtually all the excess CO2 observed in the atmosphere since the advent of the industrial age.
Think mass isotopic balance
