In response to the Danish Committee on Scientific Dishonesty's
condemnation of Bjorn Lomborg and his arguments against the
anthropogenic global warming thesis, the Danish Ministry of Science has
issued a paper attacking the DCSD's lack of scientific rigor and use of
improper standards in its condemnation.

Sci-Am has worked to suppress:

supports arguments that Antarctica has been ice bound since the
Miocene:

"Title: The unique polygons and sedimentation process of a
debris-covered glacier in Mullins Valley and Beacon Valley, Antarctica

Andrew M. Lorrey, Dept. of Geological Sciences University of Maine 

Beacon Valley is located in the western Dry Valleys, Antarctica,
adjacent to the East Antarctic Ice Sheet (EAIS). Three Wilsonian
shallow-core glaciers are prominent and unusual features contained at
the heads of Beacon Valley tributaries. These Wilsonian, or
debris-covered glaciers, may represent some of the only possible modern
terrestrial analogs to similar ice bodies seen on Mars. Polygons cover
the surface of the debris-covered glacier that fills part of upper
Beacon Valley and Mullins Valley. A survey of the polygons indicates
that landforms mature with distance from the equilibrium line. The
polygon morphology highlights the transport path of the buried ice in
upper Beacon Valley, which can be sourced to the cirque (accumulation
zone) at the head of Mullins Valley. The buried ice in upper Beacon
Valley is part of a coherent, massive ice body of glacial origin.

A gray diamicton is draped over the buried ice in Mullins Valley and
upper Beacon Valley. It has textural and weathering characteristics
akin to englacial, buried ice sediment. This diamicton is classified as
a till that formed from sublimation of buried ice. The sublimation till
(28% sand, 69% gravel, and 3% mud) is sorted by narrow contraction
cracks in the buried ice that results in sand wedge deposits (83% sand,
11% gravel, and 6% mud). The grain-sizes that comprise sublimation till
and sand wedges indicate that sediment is initially derived from
sublimation of the buried ice.

Deep polygon trenches develop over thermal contraction cracks in the
buried ice, and create traps for wind-blown sediment (reworked
sublimation till, sand wedge sediment and volcanic ash.) The tops of
some contraction cracks were void of sediment, indicative of a sediment
starvation. In this case, any primary volcanic ashfall could descend
directly into active sand wedges. As sublimation occurs, sand wedges
containing volcanic ash can slump over the sublimation till and buried
ice.

The stratigraphy of massive weathered sand, with stringers of volcanic
ash, resting on sublimation till and buried ice is widespread in upper
Beacon Valley. Because the contraction cracks and sand wedges are
secondary to the buried ice, the ashes contained in them can afford a
minimum age for the buried ice. This study supports the concept of the
ash chronology previously used (Sugden et al., 1995) to date the buried
ice at late Miocene age, and argues for persistent polar conditions in
Beacon Valley since that time." -end abstract-

He is currently working on using live and subfossil Kauri tree ring
data collected from New Zealand's north island to extend the
dedrochronological record back as far as 50,000 years. Kauri tree-ring
data established to date demonstrates consistency with known El-Nino
Southern Occillation records. 

Preliminary word from Drew says that the El Nino tree-ring record,
combined with his Antarctic work, will lend to the conclusion that
there is no danger of collapse of Antarctic Ice Caps with any amount of
global warming that could be created by anthropic means.
