What could this sentence mean?

Let’s look at some IPCC “contradictions” (areas where the observed facts contradict the IPCC claims):

Contradiction #1:
IPCC projects global warming at a rate of 0.2C per decade in the early 21st century; so far the first 8 years of the 21st century have shown cooling at an average rate of around 0.1C per decade. Oops!

Contradiction #2:
IPCC states that the rate of sea level rise has increased in the latter part of the 20th century, switching from tide gauge records to satellite altimetry; the tide gauge record shows a slight decrease in sea level rise in the second half of the 20th century, as compared to the first half. Hmm.

Contradiction #3:
IPCC states that changes in solar irradiance since 1750 are estimated to cause a radiative forcing of only 0.12 W/m2, equivalent to a net warming of around 0.02C; several studies by solar scientists conclude that the 20th century warming caused by the unusually high level of solar activity is around 0.35C. Ouch!

Contradiction #4:
IPCC states that the warmth of the last half century is unusual in at least the previous 1,300 years, ignoring overwhelming physical and historical evidence of a warmer global Medieval Warm Period. Huh?

Contradiction #5:
IPCC claims that the satellite temperature record has shown a faster rate of tropospheric warming than that at the surface, confirming the anthropogenic cause of warming; both the satellite and radiosonde record show less warming than the surface record. Oops!

Contradiction #6:
IPCC models all assume a strongly positive feedback from clouds with warming, resulting in 1.3C of the total assumed 2xCO2 climate sensitivity of 3.2C; actual physical observations show a strongly negative net feedback from clouds of around the same order of magnitude; correcting the 2xCO2 climate sensitivity for this factor brings it to around 0.6 to 0.8C, rather than 3.2C. Ouch!

Contradiction #7:
IPCC states confidently that the upward distortion of the surface temperature record due to the urban heat island effect has a negligible influence of less than 0.006C per decade; many studies from all over the world show that the UHI influence is thirty to fifty times as great as claimed by IPCC. Oh, oh!

There are many more, but I’ll just list these seven to start with.
