Re: Infrared radiation
- Some of the surface IR goes directly to space.
The surface radiates it better than the nearby air,
as evidenced by the creation of fog and dew. It is
this radiation that GHG intercept. If the trip back
out is in any way delayed then there is an aggragate
increase of heat in the system, even if it reaches a new
equilibrium.<br><br>Flaney, I ask for comment on these two
observatons.<br><br>1) Since the mechinism or returning heat to space is
indesputably lengthened (but not how much) there is an
increased heat level somewhere. Where is it, and how
quickly is it passed on?<br><br>2) The melting of the
artic cap, suggests the equilibrium has not been
reached. As this is a dynamic process that can not
continue past the last iceberg.
- This group started in 1999 and got its first posting on volcanos in
2001. BUT you got nothing nada on the underwater volcano that
erupted or formed off Oregon Coast.
Let me check if you got anything on NOAA.
