There they go again. The global warming establishment and the media are crowing about 2010 being in a tie for the “hottest year" ever. Everyone from Senator John Kerry to Joe Romm are screaming that this is “proof” the planet is burning up in a Co2 induced hell -- and it's your fault!
It is time for Climate Depot to do a point-by-point rebuttal to the latest round of temperature data nonsense. Let's begin:
Below are excerpts from the January 13, 2011 UK Telegraph's coverage of the warmists' claim of the “hottest year" ever.
UK Telegraph Headline Claim: “Flood warnings: hottest year confirms global warming say experts -- Last year was the joint warmest on record, according to new figures from NASA, that experts say confirm the case for man-made climate change.”
Climate Depot Response: This is pure politics, not science. The "hottest year" claims confirm the case for political science overtaking climate science. The “hottest year” claim depends on minute fractions of a degree difference between years. Even NASA's James Hansen, the leading proponent of man-made global warming in the U.S., conceded the "hottest year" rankings are essentially meaningless. Hansen explained that 2010 differed from 2005 by less than 2 hundredths of a degree F (that's 0.018F). "It's not particularly important whether 2010, 2005, or 1998 was the hottest year on record," Hansen admitted on January 13. According to NASA, none of agencies tasked with keeping the global temperature data agree with each other. "Rankings of individual years often differ in the most closely watched temperature analyses — from GISS, NCDC, and the UK Met Office — a situation that can generate confusion."
Meteorologist Dr. Ryan Maue of Florida State University ridiculed the "hottest year" rankings and Hansen's admission that it "was not particularly important" which year was declared the "hottest." "Well, then stop issuing press releases which tout the rankings, which are subject to change ex post facto," Maue demanded in a January 14 commentary at WattsUpWithThat.com.
The “warmest year” claim falls apart even further when you look at even slightly longer time scales. Climatologist Patrick Michaels explained to USA Today on January 12: “If you draw a trend line from the data, it's pretty flat from the 1990s. We don't see much of a warming trend over the past 12 years.” Also note that the planet has warmed since about 1850, the end of the Little Ice Age.
The declaration that we are experiencing a tie for the "hottest" year is purely a political statement because these claims are based on year-to-year temperature data that differs by only a few hundredths of a degree. NASA asserts that the trend over the last decade is the most important factor, but this claim does not hold up to scrutiny either. See: German Climate Professor Werner Kirstein Slams 'Climate Religion': Refutes claims of 'hottest decade' as 'a joke' -- 'Determining a global avg. is a tricky business and in the end is only a theoretical value'
MIT's Richard Lindzen: Earth is never in equilibrium: 'Global warming enthusiasts are arguing that the past decade has been the warmest on record. We are still speaking of tenths of a degree, and the records themselves have come into question'
MIT's Richard Lindzen: 'For small changes in climate associated with tenths of a degree, there is no need for any external cause'
MIT's Richard Lindzen: 'Lull in warming was unsurprising, given an earlier 'obsessing about tenths of a degree in the 1980s and early 1990s': 'Global temperature just fluctuates. I think the best explanation is the ocean. The timescale for ocean circulations can be decades.'
Meteorologist Art Horn: 'To say the 2010 was tied with the warmest year on record is essentially meaningless when viewed in a true historical context': 'The reason they do not give this record its true historical context is because their statement is really political'
Science Corrupted: It's 'the hottest year on record', as long as you don't take its temperature -- Activist James Hansen's claims based on 'pure conjecture' -- Hansen's Climate Con: 'The parts of the world which GISS shows to be heating up the most are so short of weather stations that only 25 per cent of the figures are based on actual temperature readings'
