Carbon dioxide is not a pollutant.
Long-term CO2 enrichment studies,
demonstrate that rising CO2 is:
-- growth-enhancing,
-- water-conserving,
-- stress-alleviating,
for both terrestrial and aquatic plants.
Rising CO2 content is greening the Earth.
Almost 4,000 experiments,
on over 550 plant species,
reveal nearly all plants,
have increased dry weight,
or biomass, in response to
atmospheric CO2 enrichment.
Over 2,000 experiments,
on almost 500 plant species,
reveal nearly all plants,
experience increased rates,
of photosynthesis, in response to
atmospheric CO2 enrichment.
Forest growth rates,
have increased gradually,
since the Industrial Revolution.
Modest increases in air temperature,
increase carbon storage in forests,
and their soils.
The carbon-sequestering capability
of Earth’s vegetation will also increase,
as the Earth greens, reducing any
CO2-caused global warming.
Rising CO2 increases concentrations
of plant hormones that stimulate cell division,
cell elongation, and protein synthesis.
Rising CO2 enhances flower pollination,
and nectar production, leading to increased
fruit, grain, and vegetable yields,
of agricultural crops.
Rising CO2 causes plants to
reduce the openness of their stomata,
reducing water loss from transpiration,
helping the plants to use water more efficiently.
If air temperatures rise,
the growth-promoting effects,
of atmospheric CO2 enrichment,
will rise even more.
Rising CO2 increases biomass,
of many agricultural crops and grasses,
even when soil nitrogen concentrations,
would tend to limit their growth.
