Default Why is it so difficult to answer three simple climate questions?

This piece of crap repeats the insufficient
data fallacy at least three times. Take a
introductory statistics course.

The three simple questions that were posed we

1.. Is it the case that CO2 increased by 5 per cent since 1998
whilst global temperature cooled
over the same period? If so, why did the temperature not increase; and
how can human emissions be
to blame for dangerous levels of warming?


There was no statistically significant cooling since 1998,
an extrem El Nino warming event.



2.. Is it the case that the rate and magnitude of warming between
1979 and 1998 (the late 20th
century phase of global warming) were not unusual as compared with
warmings that have occurred


It take 30 years to establish a statistically significant climate
trend.
============================
I believe the 30 year rule was Hansen's which you adopted.



3.. Is it the case that all GCM computer models projected a steady
increase in temperature for
the period 1990-2008, whereas in fact there were only eight years of
warming were followed by ten
years of stasis and cooling?


Another period to short to establish statistical significance.

================
In your opinion but there it is nevertheless. 8 years of warming, 10
years cooling.
