Increased CO2 in the air
is responsible for
increased plant growth.
25% to 50% of man made
CO2 emissions, are absorbed
by plants, increasing global
plant growth (biomass).
This is often described as a
“greening of the Earth”.
CO2 especially benefits plants
that are adapted to dry climates --
they become more efficient
at photosynthesis, growing faster
without using more water.
There's an experimental forest
in Germany with a continuous record
of forest growth since 1870.
Since 1960, the growth rate of
individual trees has increased
by 32% to 77%, consistent with
thousands of lab and field studies
on the effect of increased CO2 levels
on plants.
Greenhouse operators worldwide
inject additional CO2 into their
greenhouses to increase the growth
rate of their plants.
The optimum level of CO2
for plant growth is between
800 ppm and 3,000 ppm of CO2
in the air, versus 400 ppm
in the air today.
Every species of life on Earth,
(plants, humans and animals),
descended from ancestors that
lived and thrived in climates with
much higher CO2 levels than today.
There is absolutely no scientific proof
increased CO2 will result in a disaster,
or even any mild negative effects.
CO2 levels have been higher during
almost all of the history of life
on Earth, than it is today.
We are told by many scientists
that we should be worried about CO2
levels moving higher, based on
junk science, when we should
be worried about CO2 levels
sinking lower, based on real science!
CO2 concentration have been dropping
for the past 100 to 150 million years,
until roughly 1750.
Earth’s climate fluctuates between
long periods of glaciation, and
short periods of interglacial climate,
similar to the present climate.
The present Holocene interglacial
has already lasted longer than
some previous interglacial periods.
Some scientists claim Earth,
since 2000, ended the warming
trend that started 20,000 years ago,
and is reversing to a cooling trend,
heading into next 100,000-year cycle
major glaciation -- I hope they
are wrong.
The peak temperature in this
Holocene interglacial period,
believe it or not, was during
the Holocene Optimum
between 5,000 and 9,000
years ago.
The Little Ice Age, from 1250 to 1750,
was the coldest about 300 years ago,
during the late 1600s, with the low
solar activity of the Maunder Minimum
causing a cold uncomfortable climate ...
very likely to have been the coldest climate
since the Holocene Optimum period.
The bottom line:
Our planet us always warming or cooling,
but there is only one time to worry --
-- worry when our planet is cooling,
and the oceans are absorbing more
and more CO2, and green plant growth
is stunted from too little CO2
... just like 20,000 years ago.
