Replies to Critics

The Nongovernmental International Panel on Climate Change has been vigorously attacked by some environmentalists and global warming alarmists who view it as a threat to their claim of a “consensus” in favor of their extreme views. We reply to some of their specific comments in the essays linked below. Most of these criticisms simply recycle claims about science, consensus, and The Heartland Institute that have been debunked many times already.
