Stockwell asks: Is the Atmosphere Still Warming?

Guest post by Dr. David Stockwell I suspect that the only really convincing evidence against global warming is a sustained period of no global warming or cooling — climate sensitivity and feedbacks are too esoteric. I have followed the recent … Continue reading
