Climate models provide "answers"
to all conceivable questions
about the future climate.
Political decision-makers love them.
But the predictions are always wrong !
On average, climate computer models
predicted triple the global warming
that actually happened since 1979.
And no model predicted the lack of global
warming from 2003 through 2018.
When back tested, models predicted
very little of the global warming
from 1910 to 1940, on average.
Rainfall across southern Europe
has risen for several decades,
the opposite direction of what
was projected by climate models !
A research team
led by Timm Hoffman
compared model projections
with actual vegetation
development in southern Africa,
using historical photos.
In contrast to model projections,
no significant long-term trend
in precipitation could be observed.
Vegetation belts were
supposed to shrink,
but they actually expanded.
From the study abstract
published in the journal
Anthropocene in March 2019:
"Most projections of climate change
for southern Africa describe a
hotter and drier future
with catastrophic consequences
for the environment and
socio-ecological sustainability
of the region."
"Rainfall, however, apparently,
has not changed significantly."
"Results from analysis, of 1,321
repeat historical photographs,
indicate broad trends in vegetation
trajectories in the major biomes
of southern Africa."
"The Savanna biome has experienced
a rapid increase in woody plant
at rates un-anticipated by the models."
CO2 is doing its job
of greening the planet,
and not putting all life
in jeopardy.
A small increase
in the atmospheric CO2
has been accompanied by
a large increase in the
greening of the planet.
There is no ‘CO2 Armageddon!’.
We are getting a more lush, green,
and pleasant, planet as CO2 rises.
