The message
from HaaRoy contains these words:

Authors of both new papers said they were concerned that such
significant ecological changes had already been detected even though
global temperatures had risen only about one degree in the last
century.
They noted that projections of global warming by 2100 ranged from 2.5
to 10 degrees above current levels,

and this guesswork is based on......?

should concentrations of carbon
dioxide and other heat-trapping gases, which flow mainly from
smokestacks and tailpipes, continue to rise.


Have they got a source for that? How about CO2 generation
from underground coal fires, natural methane generation, etc?
What's a smokestack?

What a pity those USA scientists can't convince
your President of that.

Maybe he, like me, has heard 55 varieties of ecodoom
predicted in the last 30 years and is hard to convince. I
still haven't heard a public recantation from those who told
us all that a new ice age was coming upon us; that Iraqui
oil fires would deposit soot on the Himalayas and flood
Bangladesh; and that limits to growth would make us run out
of a large number of basic raw materials and make us choke
on our own refuse.
