Here are just a few of Al Gore`s many fallacious claims, courtesy of SEPP
THE GORONS (courtesy of Lord Monckton)
Some of the errors in Al Gore's movie An Inconvenient Truth ·
Gore, aiming to undermine the significance of
previous warm periods such as that of the Middle
Ages, promoted the 1,000-year "hockey stick"
temperature chart (debunked by McIntyre & McKitrick, 2005).
Gore showed heart-rending
pictures of the New Orleans floods and insisted
on a link between increased hurricane frequency
and global warming that is not supported by the
facts (IPCC, 2001, 2007). ·
Gore asserted that today's Arctic is experiencing unprecedented
warmth while ignoring that Arctic temperatures in
the 1930s and 1940s were as warm or warmer (Briffa et al., 2004).
Gore did not explain that Arctic
temperature changes are more closely correlated
with changes in solar activity than with changes
in atmospheric CO2 concentrations (Soon, 2005).
Gore did not explain that the Sun
has been hotter, for longer, in the past 50 years
than in any similar period in at least the past
11,400 years (Solanki et al., 2005).
Gore said the Antarctic was
warming and losing ice but failed to note, that
this is only true of a small region; the vast
bulk of the continent has been cooling and
gaining ice (Doran et al., 2004).
Gore mentioned the breakup of the
Larsen B ice shelf, but did not mention
peer-reviewed research, which suggests the ice
shelf, did not exist 1,000 years ago (Pudsey & Evans, 2001).
Gore hyped unfounded fears that
Greenland's ice is in danger of disappearing. In
fact its thickness has been growing by 2 inches
per year for a decade (Johanessen et al., 2005).
Gore falsely claimed that global
warming is melting Mt. Kilimanjaro's icecap,
actually caused by atmospheric dessication from
local deforestation, and pre-20th-century climate
shifts (Cullen et al., 2006). ·
Gore said global sea levels would swamp Manhattan,
Bangladesh, Shanghai and other coastal cities,
and would rise 20ft by 2100, but the UN estimate
is just 7in to 1ft 5in. (IPCC, 2007; Morner, 1995, 2004, Singer, 1997).
Gore implied that a Peruvian
glacier's retreat is due to global warming,
failing to state that the region has been cooling
since the 1930s and other South American glaciers
are advancing (Polissar et al., 2006).
Gore blamed global warming for
water loss in Africa's Lake Chad, though NASA
scientists had concluded that local water-use and
grazing patterns are probably to blame (Foley & Coe, 2001).
Gore inaccurately said polar
bears are drowning due to melting ice when in
fact 11 of the 13 main groups in Canada are
thriving, and polar bear populations have more
than doubled since 1940 (Taylor, 2006).
Gore said a review of 928
scientific papers had shown none against the
"consensus". In fact only 1% of the papers were
explicitly pro-"consensus"; almost 3 times as
many were explicitly against (Peiser, 2006).
Gore showed a link between
changes in temperature and in CO2 concentration
in the past 500,000 years, but did not admit that
changes in temperature preceded changes in CO2
concentration (Fischer et al., 1999).
