GISS December Update

January 16, 2013

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..

 

PS

I have had a reply from Reto Ruedy at GISS about the latest modifications to historic temperature records. I’ll post this up later.

    I was confident that the latest data would show a dramatic decline above seasonal avg. Will this be factored in to the data, or “smoothed over?” Any bets?

    Ok. I had seen brief articles stating that we seemed to be heading for a third la-nina. I suspect that may mean that the drought will continue this year……?

    What is the confidence level on a third la-nina?
