I agree with you bussard. I've worked with chemists who work in the field of measuring CO2 concentrations, etc. They attest that warming is a real effect overall. The physics of CO2 and sunlight is well understood (though there's more to the story). It's very hard to predict the effects of course. The trend is clear (global average), though the rate has so far been less than it could have been. Likely most of that is due to the ocean sinking carbon. Every week we can read about the effects. The Republican mayor of Miami Beach can testify that rising sea levels is a real thing. They deal with it all the time now. Coral seems to be dying off in Australia. 50 degree days in the Middle East. More fires affecting more people. More uncertain weather. More rain for some of us.
That's all a pretty big deal. But I understand how it's hard to feel positive about dealing with something that seems far away and would hit my pocket book hard with little apparent benefit to me. Political solutions are fraught with unintended consequences. A carbon market is actually one of the better solutions to incentivizing reduction in CO2 emissions, but I worry that it won't have the desired effect, but just drive inflation.
Folks like us will adapt and change to meet how things work out in the future. But in the meantime, some of the world's most vulnerable people will face the full brunt of a warmer climate. We're talking millions of people, like nearly the entire country of Bangladesh (you know where all your clothing comes from) which is at sea level. Just something to keep in mind.
I think it's a bit ironic that of all people, farmers would be most resistant to the idea that humans affect their environment, often in negative ways. Our livelihoods are directly at risk (everyone complained about the wet harvest this year!) when things get unpredictable.
I saw a picture in a newspaper of a rally against the PM in Medicine Hat and someone was holding a sign saying, "CO2 is our friend." That sort of thing doesn't help us look any smarter! They sky may or may not fall, but a little education won't hurt us.
