Should we include data from the last glacial maximum 18kya if we had it too? How about the Medieval warm period?
We still have long term averages out there. It’s just a different dataset from the daily and monthly norms.
Well I think it’s okay to do it this way. Times and climate change. At some point, what thy oxen felt during the Civil War shouldn’t have an effect on what we should expect today. But 30 years seems short to me. I think 50 would be better.
CON Jan normals have gone from 29.8/7.4/18.6 to 31.6/12.9/22.3. A climb of 3.7F in the last 30 years.
So I’m a little indifferent to a 2F or 3F BN Jan in current times considering it would’ve been AN when I was growing up in the 90s. -10s there should be par.
