Wow, Dr. Spencer commented on my wall, haha, was so happy. I have heard him first in 2009 in NYC, 2nd ICCC by the Heartland Institute. Since I was not so familiar with the highly technical aspects of climate science that time, was struggling with a very steep learning curve right there at the conference, I did not fully comprehend his talk and discussion about positive vs. negative cloud feedbacks to more CO2 added to the atmosphere, related topics. That conference was a start for me to read more about the technical aspects of climate science. I was visiting his blog, WUWT, others more regularly.
