On the top four Most Wanted list

Cartoon excerpt (Greenhouse gases, carbon dioxide, methane, nitrous oxide, fluorinated gases f-gas) from the digital book of cartoons on climate change, "Little Climate: We Need to Talk About Climate Disruption" by Suzanne Chew.

A quick round-up of the Top Four Most Wanted greenhouse gases that are too hot to handle!

Carbon dioxide

40% higher than before our soot-soaked Industrial Revolution began! Comes from the burn, baby burn of fossil-fuels.


150% higher than before! 80 times the warming power of carbon dioxide (when measured over twenty years)! Comes from natural gas leaks (hello, fracking!), rotting sewage waste (lovely!) and the belching melodies of our cows and sheep.

Nitrous oxide

20% higher than before, and 265 times the warming power of carbon dioxide! Hangs around in our atmosphere for 120 years before breaking down. Comes from excess chemical fertilizers that supercharge normal soil bacteria on farms into little nitrous oxide factories, and industrial processes that make synthetic nylon (also from burning fossil fuel and rotting waste).

Fluorinated gases, or F-gases!

Completely man-made, these bionic bad boys do not occur naturally. 10,000 times to 20,000 times the warming power of carbon dioxide, with a lifetime anywhere from 200 to 50,000 years – once they get the keys to the house they leave beer cans around and never take out the trash! Why do we invite them in? Ironically, they keep us cool – they’re used as common refrigerants in our air-cons, fridges and chillers. Guess what seeps out when all these are sent to the landfill?
