So, are such people skeptics of global warming, or are they skeptics of the anti-global-warming crowd? I don't not understand the term.
Anthropogenic global warming or AGW. Means caused by man. AGW sceptics (me) doubt man’s influence is profound enough to alter the climate.
anthropogenic (nthr-p-jnk)
Caused or influenced by humans. Anthropogenic carbon dioxide is that portion of carbon dioxide in the atmosphere that is produced directly by human activities, such as the burning of fossil fuels, rather than by such processes as respiration and decay.
