I don't speak for all republicans in that generalization you just made but I do prefer we approach this scientifically rather than the emotionally laden screeds we see in this thread.
At some point, you were told CO2 levels were too high and had the crap scared out of you with apocalyptic endings if we didn't do something *right now*. Did it never really occur to any of you to ask any questions about this? I mean I know that you're not supposed to question this but it's kind of human nature to be a little curious. If it's too high, there must be some kind of reference to compare it to. If there's not, as it seems you guys believe, then saying it's too high has literally no rational meaning. It's just scare tactics.
Here's some reference points.
- At 500 ppm CO2, plants begin to see significant impacts on growth and yield rates
- At 280 ppm, plants in the C4 category begin dying and others are severely impacted
- It's hard to get a perfect number but around 170 ppm we see all plant life dying
- In all our measurements throughout planetary history, the lowest we've ever seen is 180 ppm
The record low ppm's occur at the end of ice ages where the cold has driven CO2 levels down. As the planet warms, CO2 levels rise. Please note the order of events on that - temperature drives CO2, not the other way around. We saw 180 ppm as we exited the little ice age just as the industrial revolution kicked off. Any one of you can find this out if you just have the courage to ask a couple of questions instead of
meekly going along.
OK, so, we're at 415 ppm today which is, according to you guys, is the end of the world stuff. So what you're saying is we want to get CO2 levels down as close as we can to a level that would result in the death of plants on a global scale. In fact, we're damn near there already.
So how low do you want to go? How close to the abyss do we need to get to satisfy warmist fears? We sure as hell don't want to go below 180 ppm and I doubt we could even if we wanted to but if you say it should go lower then you really are advocating for the end of life on the planet (maybe some bacteria survive). If your idea is getting around 280 ppm, then you're saying we want to be right at the razor's edge of killing off plant life. You guys really want to stare into the abyss.
The reality is, when we look at history and use some basic science rather than emotion, CO2 levels are catastrophically low. We need it to increase, a lot. Greenhouse operations routinely use CO2 generators to help their plants, routinely pushing CO2 levels to 1000-1500 ppm. Some even go as high as 1800 ppm.
So what should CO2 levels be? I'd say at least 1000 ppm to give us the safety margin we need. 1200 ppm would be even better.
