doing this has been to 1) first of all, to investigate if any fears whatsoever are remotely justified for «

In my earlier posting, I tried to make the distinction that global climate change (all that is changing in the climate system) can be separated into: (1) the global warming component that is driven primarily by the increase in

about an equilibrium reference point, which therefore
do not contribute to the long - term trend.
