Not exact matches

The researchers believe the greening is a response to higher atmospheric carbon dioxide inducing decreases in plant stomatal conductance — the measure of the rate of passage of carbon dioxide entering, or water vapor exiting, through the stomata of a leaf — and increases in soil water, thus enhancing vegetation growth.

«We measure growth rate of certain tundra species and the vegetation composition and abundance.

To examine historical changes in growth and mortality rates of the vegetation there, the scientists looked at forest biomass, the cumulative result of past growth.

If it takes 100 plus years to double the concentration of CO2, and if the equilibrium response is a 2C increase (Pierrehumbert, «Principles of Planetary Climate», p 623), and if the increased CO2 produces increased vegetation and crop growth, then the present rate of development of non-fossil fuel power and fuel generation is more appropriate than an Apollo type project or attempt to get rid of all fossil fuel use by 2050 starting now as fast as can be done.

So if, hypothetically, human activities had instead cut CO2 emissions and increased CO2 SOC / Vegetation by a combined amount of 2.2 GtC / year evenly across every month of 2017 then the Annual Mean Growth Rate for 2017 would have been about -0.27 PPM / Yr.

There are two primary externalities that result from our emissions of carbon dioxide into the atmosphere — 1) an enhancement of the greenhouse effect, which results in an alteration of the energy flow in the earth's climate and a general tendency to warm the global average surface temperature, and 2) an enhancement of the rate of photosynthesis in plants and a general tendency to result in more efficient growth and an overall healthier condition of vegetation (including crops).
