Dr. John Christy’s Change of Heart?

Postby KeithE » Fri Jun 13, 2014 10:29 pm

Third warmest May in satellite record might portend record-setting El Niño

Quotes from Christy:
"The long-term baseline temperature is about three tens of a degree (C) warmer than it was when the big El Niño of 1997-1998 began, and that event set the one-month record with an average global temperature that was 0.66 C (almost 1.2 degrees F) warmer than normal in April 1998."


"With the baseline so much warmer, this upcoming El Niño won't have very far to go to break that 0.66 C record," Christy said. "That isn't to say it will, but even an average-sized warming event will have a chance to get close to that level.""

The immediately above quote was replaced since I gave the same quote twice. Both are in the link above. Bad “paste" job.

The 0.66C record anomaly ("T Departure from the 1098-2010 avg” on their plot) is the highest of their (UAH’s) reduction of the satellite data.

May summary report:
Global climate trend since Nov. 16, 1978: +0.14 C per decade

May temperatures (preliminary):
Global composite temp.: +0.33 C (about 0.59 degrees Fahrenheit) above 30-year average for May.
Northern Hemisphere: +0.33 C (about 0.59 degrees Fahrenheit) above 30-year average for May.
Southern Hemisphere: +0.33 C (about 0.59 degrees Fahrenheit) above 30-year average for May.
Tropics: +0.17 C (about 0.31 degrees Fahrenheit) above 30-year average for May.


Christy used to believe the trend was negative. Now it is 0.14C/decade. He is sounding almost "alarmist” these days.
