No kidding. The comment was sarcasm. Global warming apologists blame the industrial revolution for global warming. Back in the 1970s, the same environmental kooks were stating that the planet was headed back to another ice age due to global cooling. So, the industrial revolution has had absolutely nothing to do with global warming or there would have been evidence of global warming long before the 1980s (when the global warming theory came into existence).
That is, unless one believes the industrial revolution causes both global cooling and global warming, which would be a rather absurd contention.
