The problem with computer models

Is that reality doesn't always agree with them.

Point 1: There are… serial, serious failures of the computer models of climate

….the computer models upon which the UN’s climate panel unwisely founds its entire case have failed and failed and failed again to predict major events in the real climate.

a. The models have not projected the current multidecadal stasis in “global warming”:

b. no rise in temperatures since 1998; falling temperatures since late 2001; temperatures not expected to set a new record until 2015 (Keenlyside et al., 2008).

c. nor (until trained ex post facto) did they predict the fall in TS from 1940-1975;

d. nor 50 years’ cooling in Antarctica (Doran et al., 2002) and the Arctic (Soon, 2005);

e. nor the absence of ocean warming since 2003 (Lyman et al., 2006; Gouretski & Koltermann, 2007);

f. nor the behavior of the great ocean oscillations (Lindzen, 2007),

g. nor the magnitude nor duration of multi-century events such as the Mediaeval Warm Period or the Little Ice Age;

h. nor the decline since 2000 in atmospheric methane concentration (IPCC, 2007);

i. nor the active 2004 hurricane season;

j. nor the inactive subsequent seasons;

k. nor the UK flooding of 2007 (the Met Office had forecast a summer of prolonged droughts only six weeks previously);

l. nor the solar Grand Maximum of the past 70 years, during which the Sun was more active, for longer, than at almost any similar period in the past 11,400 years (Hathaway, 2004; Solanki et al., 2005);

m. nor the consequent surface “global warming” on Mars, Jupiter, Neptune’s largest moon, and even distant Pluto;

n. nor the eerily-continuing 2006 solar minimum;

o. nor the consequent, precipitate decline of ~0.8 °C in surface temperature from January 2007 to May 2008 that has canceled out almost all of the observed warming of the 20th century.

As Monckton states, the computer models are demonstrable failures.
