Note how Janice quote mines my comments

<quote>We may not hear from Janice further on this topic but to those
interested in the science behind the fact of global warming, these
excellent papers do much to lay to rest the almost desperate attempts
by some to find anything but human causes for the recent global
warming.</quote>

Such behavior seems rather at odds with a Christian approach and
certainly with a scientific approach.

In the mean time the news is not getting better

Remember how the Southern Oceans were once seen as a large sink for
the increased CO2? Seems that much of the ocean may be saturated
already.

Southern Ocean saturated

<quote>Around half of all human-produced CO2 is removed from the
atmosphere by the oceans, slowing global warming. Now, a study shows
that the Southern Ocean, one of the largest carbon sinks, is absorbing
less CO2 than expected relative to atmospheric levels of the
greenhouse gas.</quote>

CO2 rising fast

<quote>Worldwide emissions of man-made carbon dioxide are rising
faster than even the worst case predictions made by scientists. The
increase in CO2 levels, which averaged 1.1% per year from 1990 to
1999, leaped to over 3% per year from 2000 to 2004, according to a new
study by Michael Raupach of the Commonwealth Scientific and Industrial
Research Organisation, Australia, and international
colleagues.</quote>

And some unfortunate impacts of global warming, this time on the
commercial fisheries of the North American rainbow trout.

And finally, while some believe that reforrestation is an answer to
global warming, the following article may give some pause for thought

Barking up the wrong tree?

VICTORIAN RAINFOREST NETWORK

It is often assumed that global warming can be reduced by planting
trees, which soak up carbon dioxide from the atmosphere. However,
trees also change the planet's surface albedo, or its ability to
reflect sunshine.

Govindasamy Bala of the Lawrence Livermore National Laboratory in
California and co-workers compared a deforested world with a standard
world using an integrated global carbon cycle and climate model. A
treeless world would be 0.3 K cooler by 2100, they claim. Although
this world would have higher carbon dioxide in the atmosphere and
oceans, it would reflect more sunlight, lowering the temperature.

Lower CO2 but higher temperatures due to the albedo effect. Ironic isn't it?
