BBC exaggerated warming trend in David Attenborough’s TV show “Africa”

This story has been running the rounds. “BBC exaggerated climate change in David Attenborough’s Africa”. Donna Laframboise has just dug deeper into the scam and shreds the BBC’s shoddy work further in – “The Workshop Presentation that Never Was”

Thought it worth restating that I have pointed out in Aug 2006 “Satellites vs surface, amazing agreement over the USA” then revisited the theme again
in 2010 and 2012 – The Jones et al CRUT trends are not worth a cup full of warm spit when compared against satellites lower troposphere trends over the large African grid-box 20S to 20N and 10E to 40E. Obviously something seriously wrong with surface data. I love the way satellites and surface agrees over the USA – CRU would not want any possums stirred up there.
Why is it that unpaid sceptics all over the world have to correct the work of highly paid IPCC warmists ?

  1. Can I venture that the reason unpaid sceptics all over the world have to correct the work of highly paid IPCC warmists is that those highly paid IPCC warmists have a strong vested interest in ensuing that they remain just that, highly paid IPCC warmists.

  2. The RSS satellite temperature series for the lower troposphere can be found here:
    www.remss.com/data/msu/monthly_time_series/RSS_Monthly_MSU_AMSU_Channel_TLT_Anomalies_Land_and_Ocean_v03_3.txt
    One of columns is for the continental US. The linear trend from 1979 through 2012 is 0.20°C/decade.

    The National Climate Data Center (NCDC, part of NOAA) provides temperature data for the US going back to 1895:
    www.ncdc.noaa.gov/oa/climate/research/cag3/na.html
    Their ground-based temperature trend from 1979 through 2012 is 0.54°F/decade, which converts to 0.30°C/decade.

    So, Houston, we have a problem. The land-based trend is 50% greater than the satellite based trend. GCMs indicate over land the lower atmosphere should warm at a factor of 0.95x the land. For a discussion of this land amplification factor by Gavin Schmidt, see here:
