Agenda or otherwise, arguing about global warming seems pointless when so much pollution and waste is being scattered all over the place thanks to rubbish like planned obsolescence, and political rubbish like RoHS, banning incandescent light globes, and similar kinds of "green" "eco" junk policies implemented in spite of insufficient evidence/research supporting it.
Global warming and climate change is really the last thing to worry about. Not many people get into fights over the situation regarding environmental pollution, but they have a barney over a bunch of cow burps and electric farts.
I'm even "greener" than the greenies, but being "green" also involves being sensible and practical.
