What is Climate Science ?

A central issue 
in climate science, 
is whether 
human emissions 
of carbon dioxide, 
methane, and other 
“greenhouse gases”, 
are having effects
on Earth’s atmosphere, 
that could endanger life 
on this planet. 

Climate science 
is a complex subject 
with a lot of
unanswered questions. 

Simplistic claims 
about the relationship 
between human activity 
and climate change 
are jumping to conclusions.

People claiming 
to be climate scientists 
are usually specialists 
in one or a few areas 
including physics,
mathematics,
computer modeling, 
oceanography, 
meteorology, etc., 
who study just one part 
of the complex climate. 

Some physicists 
doubt whether 
the concept 
of a single 
global temperature 
should be used 
in climate research .




Science is a search 
for causal explanations 
of natural events. 

Skepticism 
is at the heart 
of science.




The Scientific Method 
is a series 
of requirements 
imposed on scientists 
to ensure the integrity 
of their work. 

The IPCC has not followed 
established rules that guide 
scientific research.




Scientific theories 
differ from observations 
by being suppositions 
about what is not 
observable directly. 

According to Popper (1965), 
a theory is scientific 
only if it can be falsified 
by observational data 
or experimentation. 

The best we can do 
is trying to 
falsify the hypothesis, 
and by surviving such tests 
a hypothesis demonstrates 
it may be close to the truth. 



It is relatively easy 
to assemble 
reams of “evidence” 
in favor of 
a point of view 
or opinion 
while ignoring 
inconvenient facts 
that would contradict it -- 
a phenomenon called 
“confirmation bias”.



The hypothesis implicit 
in the IPCC’s writings, 
though rarely 
explicitly stated, 
is that dangerous 
global warming 
is resulting, or will result, 
from human-related 
greenhouse gas emissions. 

But there must be 
direct evidence 
of human causation 
of changes in temperature, 
or other elements of climate, 
that lie outside of
natural climate variability. 

But the IPCC and other
research and advocacy groups 
make no effort to find
that direct evidence.




In addition, virtually 
no research dollars 
are available to study 
the causes 
and consequences 
of natural climate 
variability. 

Instead, 
IPCC researchers 
try to refute 
any theory or data 
that might 
compromise 
their own 
'CO2 is Evil" theory. 

Many science journals 
refuse to even consider 
publishing articles 
that question the 
IPCC's unproven claims.




The geological record 
reveals that we live on 
a dynamic planet. 

It is wrong to assume 
no climate changes 
would occur 
in the absence of 
humans.

Climate will 
be different 
in 100 years 
regardless 
of what 
humans do. 




Appealing to 
a consensus 
does not have 
a place in science, 
especially as 
a strategy 
to shut down debate.




Climate is always changing. 

To say climate change
is “man-made” 
begs the questions: 
“how much?”, and 
“how do we know?” 

No one knows how much.




The idea that the science 
of climate change is ‘settled’ 
is an absurdity !

Climate science is in its infancy.

Uncertainties abound 
in climate science. 

For one example, 
the amount of energy 
reflected back into space 
by clouds is assumed to be 
(on average) a constant, 
but even small changes 
in cloud cover, 
cloud brightness, and 
cloud height 
– all of which are known 
to vary -- can change 

the average temperature.
