[ RadSafe ] Climate change

[StevenFrey at aol.com]

Unconvincing. And the "To deny any link between greenhouse gases and the  
average Earth temperature reality is an extreme case of hubris"remark is not  
only patronizing, it's hysteria weakens your claim.
 
Since global warming proponents got caught conspiring to ostracize critics  
in the University of East Anglia email dump, global warming lost its  
credibility. Moreover, changing of "global warming" to "climate change" is  
actually refreshing, because it smacks of recognition by proponents that the  
public isn't buying it. But, what a whopper of a mistake to rename it such  
that every weather problem can be attributed to greenhouse gases. All  of it, 
all the time. You might as well cry "Wolf!".
 
Besides, why are we using RADSAF to discuss this off-topic issue,  anyway? 
MSNBC is a better forum for it.

With  regard to the 4 previously mentioned options regarding climate change 
[warmer,  colder, no change, or being hit by an asteroid], I am in the camp 
that has  come to the conclusion that the climate will move to higher 
temperatures. [We  were discussing this back in the '70s in my meteorology and 
oceanography  classes at the University of Michigan and those profs were smart 
guys.]   Any change in the solar output or axis wobble will make some small 
 changes.  Continuing to pump greenhouse gases (methane, CFCs, and carbon  
dioxide) into the atmosphere increases the heat containing capacity of the  
atmosphere. (Ok, to be technically correct, you are increasing the capacity 
of  the atmosphere to capture outgoing radiation and radiating back to the 
earth  as heat.  But, in the overall picture, it results in an increase in 
the  earth's temperature.) By analogy with solar output and axis wobble, 
compare  the water content of an 8-oz glass to that of a 16-oz glass.  No matter  
how the rate at 
which you fill the glasses, the 16-oz glass will always  contain more 
water.  Therefore, more greenhouse gases, higher  temperatures.

Look at the records in the oceanic sediment cores and the  ice cores.  When 
the greenhouse gases CO2 and methane concentrations are  high, so are all 
of the geochemical markers for increased temperature, ie, the  O18/O16 
ratios, etc.  To deny any link between greenhouse gases and the  average earth 
temperature is an extreme case of reverse hubris.

Too  many people who regularly contribute to RADSAFE tend to dismiss the 
data which  lead climatologists to be concerned about higher earth 
temperatures because it  does not fit their already formed conclusions.   Being 
flippant is  not worthy response to scientific concerns.

As always, these words are  my own and I do not intend to formulate any 
official position for my  employer.
