AGW in Latin America? What Wikipedia says...

post #1 of 2
Thread Starter 

This is the first picture on the main Spanish Wikipedia entry on global warming. Clearly, it is probably not totally accurate. It does look a bit biased, even more so than Mann's original hockey stick. This could raise some questions.

 

Do you think this means Latin America is less divided on the issue of climate change, or just more apathetic to it? 

 

Does this seem to be evidence against the belief that developing nations would never embrace the idea of carbon reduction? 

 

Or could there be some reason why Latin America is not a fair representation of the rest of the developing world? (Note that Russia, China, India and even Brazil all have more neutral images posted on their respective GW articles.)

I wouldn't make a generalization about Latin America based on a graph made by one person in the Wikipedia entry.  Here's the stated source of the temperature data.

 Source: graph drawn by Hanno using data from two sources. For the years 1000–1880, temperature estimates were taken from P.D. Jones & M.E. Mann (2004): "Climate over past millenia". Reviews of Geophysics, 42, article number RG2002. For the remainder, temperatures are based on instrumental records published on the web by P.D. Jones, D.E. Parker, T.J. Osborn & K.R. Briffa (2005) as "Global and hemispheric temperature anomalies – land and marine instrumental records". In Trends: A Compendium of Data on Global Change. Carbon Dioxide Information Analysis Center, Oak Ridge National Laboratory, U.S. Department of Energy, Oak Ridge, Tenn., U.S.A. [http://cdiac.esd.ornl.gov/trends/temp/jonescru/jones.html]

 

Note that the original 'hockey stick' was from a '99 paper and was recently updated by Mann et al.  I'm not familiar with the '04 Mann paper referenced here.
