That's true. As a pollutant, carbon dioxide is almost entirely innocuous, except for its behavior as a greenhouse gas. In that role, carbon dioxide is the most significant driver of global warming: https://en.wikipedia.org/wiki/Greenhouse_gas#Natural_and_anthropogenic_sources https://en.wikipedia.org/wiki/Greenhouse_gas#Natural_and_ant...

- aardvark291 10y agoA methane molecule is 72 times worse than a CO2 molecule in terms of "global warming potential" over a 20 year time scale and around 7 times worse over a 500 year time scale). However, we put a lot more CO2 into the atmosphere than we do methane. https://en.wikipedia.org/wiki/Greenhouse_gas#Global_warming_potential https://en.wikipedia.org/wiki/Greenhouse_gas#Global_warming_...
- mikesmith112 10y agoDoesn't that indicate methane is the low hanging fruit? I guess that assumes it's the same cost to prevent / recapture 1 molecule of methane vs. CO2... But if the next 20 yrs are the most crucial, methane sounds like a great target. seems likely; after that, technology will hopefully have stabilized our energy sources
