"(it's not politics, it is science. )"
That's right. The IPCC is all about politics and not much about science. Science, even in the world of beekeeping, is all about forming a hypothesis and then collecting all of the data that supports AND doesn't support your hypothesis. That's not what the IPCC is doing. As revealed in their leaked email traffic, they have come to their conclusion and collect only the data that supports their conclusion, don't even acknowledge that data that refutes their conclusion and "interpret" data to bend it to support their conclusion.
This same phenomenon happens in regards to beekeepers and foundationless frames. Those who have tried it only once, or never even tried it, want to tell us how wrong or bad it is. They have their agenda and look only for the proof that supports their agenda, ignoring the fact that many of us are having much success with foundationless frames.
