The same people who say "The science is settled" ... have made very wrong predictions of the future climate for over 30 years !

There is very little debate 
about climate change.

One side has been predicting
a coming climate crisis
since the late 1950's,
and using compputer models
to make similar predictions
in the past 30 years.

They falsely insist 
the “science is settled.” 

To "prove" that claim, 
they designed
complex computer
climate models 
many decades ago
to make specific 
predictions of
the future climate.

But their computer
model predictions 
are always wrong !










Very far from reality.

The average computer model
predicted triple the warming
that actually happened.

I call them computer games !

With over 60 years 
of wrong climate
change predictions,
and over 30 years 
of wrong climate
model predictions,
how can the science 
be settled ?





There's no scientific proof 
increased CO2 will result 
in disaster.

CO2 has been higher 
during most of the 
history of life on Earth,
than it is today (410 ppm). 

There's no scientific proof 
increased CO2 will cause 
any problem.

If you want to worry,
then worry about 
CO2 levels sinking lower.


There was a 
gradual 97%+ 
loss of CO2 from 
the atmosphere,
starting 550 million 
years ago, with 
CO2 at about 7,000ppm, 
to the lowest level 
of CO2, at about 200ppm
during the peak cold
of the last glaciation,
about 20,000 years ago.






The present Holocene 
interglacial warm period 
has already endured longer 
than some previous 
interglacial periods. 

The beginning of the 
next glaciation may be 
a relatively short time 
from now. 

In fact, there's a 
strong argument 
that the Earth 
is already in 
a cooling trend, 
that started 
10,000 years ago, 
after the glaciers 
that covered 
most of Canada 
had melted.

The peak temperature 
in this Holocene 
interglacial period 
was during the 
Holocene Optimum 
between 8,000 and 
10,000 years ago. 

The Little Ice Age, 
which was coldest 
about 300 years ago, 
was probably 
the coldest period 
of climate since the 
Holocene Optimum.






A somewhat warmer world, 
with a higher level of CO2 
in the atmosphere, 
would result in 
a greener world, 
with more plant biomass, 
higher yields of food crops 
and trees, and a milder climate 
in northern latitudes.

That would be good news,
not an "existential threat".





CO2 is essential for life.

Many people don't
know that and believe
a global warming crisis 
is already in progress.

But the “pause” 
in global warming,
since 2003, 
contradicts 
their belief that 
higher CO2 levels
must lead to higher 
temperatures.




The optimum CO2 level 
for plant growth 
is above 1,000 ppm.

CO2 has been 
above 1,000 ppm 
for most of the 
history of life, 
so what sense 
does it make 
to call for 
a reduction in 
the CO2 level,
from the 
current 410ppm,
with absolutely
no evidence
of catastrophic 
climate change
caused by CO2 ?
