Plants seem to like more CO2 (tip to Mad Minerva):
Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide “fertilization effect” has, indeed, caused a gradual greening from 1982 to 2010.
Increased CO2 hasn't increased temperatures the last 16 years (or from the 1940s to 1970s), so that cause-and-effect doesn't seem as solid as we're to believe. But more foliage is actual data, isn't it?
So in addition to wanting to know just what is the ideal temperature (if we're to move heaven and earth to maintain some temperature, shouldn't we have a scientific basis for defending that number?), I now want to know what the ideal CO2 level is.
Let's not be chrono-centric. Shouldn't science establish those answers first before we sacrifice personal freedoms and economic progress to defend numbers that coincidentally existed in recent memory?
