Sounds minor to me.Are you saying that adding trillions of tonnes of it to our atmosphere won't make much of a difference? It's spurring more plant growth. That's a difference. The claim it's affecting the weather doesn't stand up to scrutiny .. at least not yet.The stuff I've read doesn't seem to agree with that and I make a point of trying to read UNBIASED material . Everything has a bias. Can you give me a list of the major and minor greenhouse gases? Water vapor is #1. But why should I, you've been reading all these unbiased material. I should ask you for the list. What about methane? I assume the biggest source of methane (besides cows and us) could be the melting of permafrost in Siberia. Lately we seem to be seeing a rash of sinkholes in Siberia. I assumed that was because the planet was heating up a bit. The same reason that many home owners in Alaska suddenly find their house foundations becoming a bit unstable. You need to give me more than just telling me that CO2 concentrations don't really matter. Stay tuned, I post a lot on this stuff and you can learn from it. Do CO2 concentrations matter? Not right now. Someday maybe at much higher concentrations .. I can't rule it out. But we're not in a warmth crisis now.
