Have scientists ever protested to end long term gravy trains, err experiments?
This has to be the sweetest deal ever. Getting paid to watch trees grow.
Tree rings are great indicators of growing conditions during any one particular year. Why would more than ten years of experimentation be required to determine the effect of elevated CO2. My guess is that it has more to do with car payments than science.
Does that mean if we start scrubbing CO2 out of the atmosphere, I don’t have to mow the lawn as much?
