The Inventor of the Global Warming Hockey Stick Doubles Down. Do you foolishly do the same?

I see an ideologue, desperately trying to support a hypothesis that’s been falsified by observations.  While the majority of climate alarmists are trying to discover a physical reason that might just save the AGW hypothesis, Mann simply ignores the ‘inconvenient truth’ that the global climate has not warmed significantly for at least the past 15 years — while emissions of greenhouse gases have surged globally….

In actuality, we now have adequate proxy data from other sources, most particularly from Fredrick Ljungqvist and David Anderson.  Their separate publications agree that there has been little if any temperature rise since about 1940!  However, there was a real temperature increase between 1920 and 1940, which can be seen also in the various proxy as well as thermometer data….

Michael Mann saw something he didn’t like in the Senate testimony (Jan 16, 2014) of fiercely independent climate scientist and blogger, Georgia Tech professor Judith Curry; so he decided to say something in his NYT op-ed.  He forgot that often it is better to say nothing than to accuse Curry of peddling anti-science.

Curry has lost no time in taking Mann’s challenge and turning the tables on him:                            

“Since you have publicly accused my Congressional testimony of being ‘anti-science,’ I expect you to (publicly) document and rebut any statement in my testimony that is factually inaccurate or where my conclusions are not supported by the evidence that I provide.

During the Hearing, Senator Whitehouse asked me a question about why people refer to me as a ‘contrarian.’  I said something like the following: Skepticism is one of the norms of science.  We build confidence in our theories as they are able to withstand skeptical challenges.  If instead, scientists defend their theories by calling their opponents names, well that is a sign that their theories are in trouble.

 Curry’s final message to Mann:

 “If you want to avoid yourself being labeled as ‘anti-science’, I suggest that you are obligated to respond to my challenge.”…

 And to what purpose?  As pointed out many times, CO2 is beneficial for agriculture.  As a natural fertilizer, it accelerates the growth of crops.  Czech physicist Lubos Motl has calculated that if it were indeed possible to reduce CO2 levels to their pre-industrial value, global agriculture would suffer a strong decline and billions of people would starve to death.
