GISS December Update
By Paul Homewood
December numbers are out for GISS, and show a huge drop of 0.24C from November, from 0.68C to 0.44C.
This reflects the end of El Nino conditions during the summer, and return to ENSO neutral. Current signs indicate a possible new La Nina beginning.
For perspective, during the ENSO neutral conditions from April 2003 to March 2004, GISS averaged 0.60C.
It looks like Hansen will have to find some more adjustments..
I have had a reply from Reto Ruedy at GISS about the latest modifications to historic temperature records. I’ll post this up later.
