Arguments condensed:

• It's the sun
• It's cosmic rays
• Carbon dioxide appears to be a very minor factor.
• Water vapor is the most powerful greenhouse gas
• carbon dioxide is a very inefficient greenhouse gas
• rejects water vapor feedback
• Satellites show no warming in the troposphere
• Mars is warming

Notes:

• Accepts many glaciers are melting
• Accepts the co2 rise since the industrial revolution, although preindustrial figure slightly wrong, and says ocean warming is the cause "at least in part" of the co2 rise.
• Accepts that sunspot activity on its own cannot account for the full swings in global temperature (although confusingly the article cites Habibullo Abdussamatov as claiming evidence that "current global warming on both Mars and Earth is being caused by a long-term increase in solar irradiation")

Quotes:

"The slight increase in ground temperature has no parallel in the troposphere. If atmospheric CO2 concentration was actually a significant factor in global warming, it stands to reason that atmospheric temperatures would rise but that hasn't happened."

"To date, no one has been able to identify a link between higher CO2 concentrations and greater volumes of atmospheric water vapour"
