Celebrating 2009's great "Heaven and Earth" book, by Australian geologist Ian Plimer

 In 2009, after 12 years 
of climate science 
reading as a hobby, 
I bought Plimer's
nearly 500 page book,
and later typed 
a list of quotes.

The following article 
contains most 
of those quotes.

As a geologist, 
and real scientist, 
Plimer admitted to 
uncertainty, 
and did not make 
wild guess long
term predictions 
of the future climate
( ... that are 
always wrong, 
like most climate 
"scientists"
do these days 
... as if wrong 
predictions are 
real science ! )

I couldn't find the
book at any Michigan
library, back in 2009,
so I spent $21.95 
on my paperback 
copy.

Which to this
long retired
cheapskate 
( retired since 
January 2005, 
at age 51 ) 
meant thirty minutes 
reading the book 
in a local bookstore 
before buying it !

I read it again this year.

The main problem 
I found was enthusiasm
about the 80,000 chemical
measurements of CO2
done long ago. 

They were local 
measurements,
not representative 
of a global average,
which has been
measured in Hawaii
since 1958.

Pre-1958 
CO2 levels
are very rough 
estimates from 
Antarctica  
ice cores
... while global 
temperature estimates
from the same ice cores
are ignored.

They are ignored 
because temperature 
peaks derived 
from ice cores
led CO2 level peaks 
by hundreds 
of years --
that's right,
the temperature 
changes, caused
by unknown
natural causes 
in the past 
500,000 years, 
were FOLLOWED
by CO2 level changes 
hundreds of years later.

No one ever tried to 
to replicate those local 
CO2 measurements,
as Plimer points out,
but I can't see how doing 
so would tell us much 
of value.

Humans have added
lots of CO2 to the air,
which is not in doubt,
and more CO2 is 
expected to cause
some amount
of mild global 
warming, based on 
lab experiments.

But our current CO2
level is unusually low,
relative to the CO2 history
of our planet, so adding
CO2 to the air, boosting
green plant growth,
is good news.

Adding CO2, however,
is only good news when
done with modern pollution
controls.

Adding CO2 without those
controls, which pollutes 
the air in Chinese and 
Indian cities, is bad news.

Asian pollution 
is a real 
environmental
problem, 
which tends to be 
completely ignored 
by the so-called 
"environmentalists",
who used to care
about real pollution
in the 1970s.

For those who 
demonize CO2,
a gas that's really 
the staff of life
on our planet: 
   Offshoring 
your nation's 
manufacturing 
to Asian nations, 
does NOT reduce  
global CO2 
emissions, 
and most likely 
increases real 
pollution !
