re: #203 Bagua

Nope.

Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic (human) greenhouse gas concentrations.

very likely means at least a 90% likelihood.

IPCC AR4

“At least 90% likelihood” does not equal 100%.

Where have you seen the confidence level of evolution pegged at 100%?
