8 Natural Processes that Change Climate CO2 Fluctuations Changes in plant growth rates CO2 levels fall during the growing season and rise in the winter

The inescapable if unfashionable conclusion is that the human use of fossil fuels has been causing the greening of the planet in three separate ways: first, by displacing firewood as a fuel; second, by warming the climate; and third, by raising carbon dioxide levels, which raise plant growth rates.

The authors, a team of scientists from Princeton University and the U.S.D.A. Forest Service, uncovered plant growth rates of only 2 to 4.4 percent.

On the upside, this could increase plant growth rates and lifetimes at high latitudes, reduce skin cancer incidence, and cool the planet.

And it's happening because of carbon dioxide and global warming: «human use of fossil fuels has been causing the greening of the planet in three separate ways: first, by displacing firewood as a fuel; second, by warming the climate; and third, by raising carbon dioxide levels, which raise plant growth rates.»

It's baloney of course — the current climate is the best climate our planet has had in at least 500 years for human health and prosperity, and green plant growth rates.

The temperature, humidity, and CO2 content of the air; the nutrient solution, pH, and electro - conductivity of the water; the plant growth rate, the shape and size and complexion of the leaves — all these factors and many others are tracked on a second - by - second basis.

Some biologists state that atmospheric CO2 levels of 200 ppmv or less are getting near the lower end of the range for natural plant growing conditions and that plant growth rates increase with higher CO2 concentrations above this level (Hincke et al 2011, Coleman et al. 1993, Tilan 1992, Sage et al. 1988, Nosky et al. 1986)

«As atmospheric CO2 increases,» it stated, «plant growth rates increase.
