Global Warming Has Stopped
“Global warming” Has Stopped
N a blog post1, Bill Chameides says “global warming” is still happening. It isn’t. As
the global temperature graph below shows, all four of the world’s major global
surface temperature datasets (NASA GISS; RSS; UAH; and Hadley/University of
East Anglia) show a decline in temperatures that have now persisted for seven years.
‘Global warming’? What ‘global warming’? All four of the world’s major surface-
temperature datasets show seven years of global cooling. The straight lines are the
regression lines showing the trend over past seven years. It is decisively downward.
Chameides’ graph overleaf appears to have been tampered with to exclude the very rapid
cooling that occurred between 2007 (the curve stops in January 2007, when a strong el
Nino artificially but temporarily boosted temperatures) and 2008. The fall in temperatures
between January 2007 and January 2008, carefully not shown on Chameides’ graph, was
the greatest January-January fall since records began in 1880.
Furthermore, Chameides’s graph – instead of presenting a proper five-year running mean
– merely cherry-picks certain points on the running-mean graph (which is not itself
shown) so as to suggest, falsely, that global temperatures are still rising.
This appears a deliberate and less than honest technique, characteristic of the desperation
of those who had staked their careers and reputations on their belief in a new religion
whose principal tenet – worldwide warming – have been falsified by worldwide cooling.
Chameides’ graph appears to have been truncated to exclude the very rapid global cooling
from 2007 to 2008. Also, the 5-year running-mean curve has been deleted to allow the
blogger to select points that appear – falsely – to show continuously-rising global
The matter can be put in a longer-term perspective by showing the
