20th-century warming: less than had been thought
SPPI's authoritative Monthly CO2 Report for September 2009 reproduces a
research paper by Dr. Joe D'Aleo showing that global temperatures over the
past century, corrected for urban bias and other errors in the current
datasets, have changed by far less than official sources suggest.
- Science
Focus, pages 24-29.
"Global warming" poses no national-security threat. Fearmongers are
the real threat.
- Editorial comment: Page 3.
- The North-East Passage has been open before, so the Green
shipowner's recent stunt that got a ship round the northern coast of Russia
with the assistance of several ice-breakers is nothing new and tells us
nothing of "global warming". Pages 4-5.
- The IPCC assumes CO2 concentration will reach 836 ppmv by 2100, but,
for almost eight years, CO2 concentration has headed straight for only 570
ppmv by 2100. This alone halves all of the IPCC's temperature projections.
Pages 6-7.
- Since 1980 temperature has risen at only 2.3 °F (1.4 °C)/century,
not the 7 F° (3.9 C°) the IPCC predicts. Pages 8-10.
- Sea level rose just 8 inches in the 20th century, and has scarcely
risen since 2006. The oceans are not warming. Page 11.
- Arctic sea-ice extent is now beyond its summer low, but there was
more summer ice than there was in 2007 or 2008. In the Antarctic, sea ice
extent reached a record high in 2007. Global sea ice extent shows little
trend for 30 years. Pages 12-16.
- Hurricane and tropical-cyclone activity is almost at its lowest
since satellite measurement began. Page 17.
- CO2 residence time is about 7 years, not the 100 years imagined by
the UN's climate panel. Page 18.
- The Sun is still very quiet, but some solar activity returned at the
end of September. Page 19.
- The (very few) benefits and the (very large) costs of the
Waxman/Markey Bill are illustrated at Pages 20-23.
- We offer a special puzzle to our readers, just for entertainment. Page 30.
- As always, there's our "global warming" ready reckoner, and our
monthly selection of scientific papers. Pages 31-35.
- And finally, a Technical Note explains how we compile our
state-of-the-art CO2 and temperature graphs. Page 36.
