The EPA's Carbon Dioxide Endangerment Finding is Still Alive

The Environmental Protection 
Agency’s (EPA) 2009 
“Endangerment Finding”
              ( EF )
is the basis for EPA
regulations of carbon 
dioxide emissions 
under the 
Clean Air Act.

The EF was produced 
in response to a 2007 
Supreme Court decision, 
Massachusetts v. EPA, 
that the Clean Air Act 
Amendments of 1992 
empowered the EPA 
to regulate emissions
of carbon dioxide, 
if the agency found 
that they endangered 
human health and welfare.

The case against the EPA 
was originally brought by 
12 states and several 
environmental advocacy
 organizations. 

The Supreme Court decision, 
a narrow 5-4 verdict, 
was announced on 
April 2, 2007. 

The majority held that 
the Clean Air Act did grant 
the EPA authority to regulate 
greenhouse gas emissions 
as “air pollutants.”

President Barack Obama's EPA 
ssued a final  “finding of 
endangerment” on 
December 7, 2009.



Climate impacts in the EF
are generated by computer
models that, with one exception, 
made dramatic errors.

Computer simulations of 
global climate, using \
general circulation models 
            (GCMs) 
or Earth system models 
             (ESMs). 

The Obama Administration 
justified its interventionist 
policies with its calculation 
of a figure known as the
Social Cost of Carbon
             (SCC). 

The SCC is a 
monetary estimate 
of the damages 
supposedly caused 
by an incremental 
ton of carbon dioxide 
(CO2), the 
principal contributor 
to human-induced 
climate change, 
emitted in a given year. 

Costs are wild guesses 
produced by computer
programs called 
“integrated assessment 
models”    (IAMs). 

IAMs “integrate”  a 
speculative model 
of how carbon dioxide 
emissions will change 
the climate, with a 
speculative model of 
how climate change 
will affect consumption, 
GDP, and health. 

There was no effort made 
to include any dissenting 
opinions to their declarative 
statements, despite the 
peer-reviewed literature 
being full of legitimate 
and applicable reports 
that provide contrasting 
findings. 

Yet the authors claim 
to provide its readers
“U.S. policymakers 
and citizens” with the 
“best available science.” 



In operational weather 
forecasting, forecasters
do not simply average 
all available models.

They tend to use the output 
of a model, or a subset 
of models, that has been 
shown to perform best. 

The Russian INM-CM4 
climate model predicts 
the least 21st century 
warming, projecting only 
+1.4 degrees C. 
of global warming 
for this century, 
roughly half the average 
of all the other model

The one 'accurate' model
-- the Russian INM-CM4 -- 
predicts only modest 
warming that would 
hardly warrant an 
endangerment finding.



Climate change, in reality:
People voluntarily expose 
themselves to climate changes 
throughout their lives that are 
much larger, and more sudden ,
than those expected from 
greenhouse gases. 

The migration of the U.S. 
population from the cold North 
and East, to the much warmer 
South and West, is an example.
