Climate Science Starting to Come Around?

Maybe, but it is very, very slow. Clearly, the "raise carbon dioxide and the atmosphere warms correspondingly" hypothesis is completely falsified by 17 years of no warming while CO2 continued its rise.

Climate scientist Dr. Judith Curry today writes:

It would be great for science, and even for policy, if climate scientists would stop focusing solely on CO2-forced climate change, and look at natural internal variability and how this interacts with external forcing – both slow (e.g. solar or CO2) and fast (e.g. volcanoes).  The big issue of scientific interest (not to mention policy relevance) is abrupt climate change.  I don’t really regard the climate shifts of 1976 and 2001 to be ‘abrupt climate change’, although by some definitions these qualify.  These climate shifts are certainly of great interest and significance in and of themselves, and there are some hypotheses on the table regarding how to predict the next shift (e.g. stadium wave).
JC conclusions
The science of climate change on decadal to century timescales most definitely is not settled, in spite of the IPCC’s highly confident proclamations.  There are so many interesting and unsolved issues in climate dynamics.  At this point, climate science seems relatively irrelevant for energy policies – the goals of carbon mitigation are in place, and whether anything meaningful can be achieved in the near term is doubtful.  However, climate scientists are (in the words of Pointman)  in a hurry towards some finishing line only they could see, and acted accordingly.  I suspect that the IPCC becoming less and less relevant to the UNFCCC agenda.
I’m hoping that at some point soon, climate scientists will get fed up with trying to play politics with their science and get back to researching and debating these fundamentally interesting and unsolved issues in the science of climate dynamics, rather than attacking their colleagues for suggesting that there are other ways of thinking about climate change.
The bold-type emphasis is mine. Yes, it is long past time for climate 'science' to get out of politics and revisit the basics of climate, especially volcanoes and, most especially, solar.
