Changes in the sources of nitrogen and the composition of the phytoplankton community are more likely to account for the differences seen in the isotope data, Huckstadt said. “It looks more like a shift at the base of the food web, probably related to the transition from the Little Ice Age to current conditions, causing changes in the phytoplankton community,” he said.

There are models that predict that the interior of the East Antarctic ice sheet wouldn’t change very much, even if the West Antarctic ice sheet was taken away, » Licht said. According to these models, even if the ice sheet’s perimeter retreats, its core remains stable.

The now three-year-old Plate Climatology Theory is on the brink of total confirmation. This is the result of two just-released and very telling Antarctic research studies. Combining the results of these two studies with the massive amounts of pre-existing data it is possible to show with very high certainty that melting of West Antarctic glaciers is directly related to bedrock heat flow and chemically charged heated fluid flow from the 5,000-mile-long West Antarctic Rift System (see Figure 1).

Scientists announced today that a core drilled in Antarctica has yielded 2.7-million-year-old ice, an astonishing find 1.7 million years older than the previous record-holder
If the new result holds up, says Yige Zhang, a paleoclimatologist at Texas A&M University in College Station, the proxies will need to be recalibrated. “We have some work to do.”

The Edinburgh volcano survey, reported in the Geological Society’s special publications series, involved studying the underside of the west Antarctica ice sheet for hidden peaks of basalt rock similar to those produced by the region’s other volcanoes. Their tips actually lie above the ice and have been spotted by polar explorers over the past century.

Earlier studies had documented little change in the western Ross coastline prior to 1995, and the new study both confirmed the earlier work and extended the analysis to the present time.
This work underscores the complexity of Antarctic climate change and glacier response.

About half of the CO2 emitted by man gets absorbed by the oceans and so does not stay in the atmosphere. Here there are certain areas of the ocean that are especially efficient CO2 sinks, while others do not absorb so well. What follows is a look of the newest literature on the subject.

A commentary appearing here at the Swiss Baseler Zeitung (BAZ) slams a recently published British paper on moss growth in Antarctica that gave the impression the south polar continent was greening up due to climate change.
The BAZ writes that the paper is an example of “how today science is manipulated and used for political purposes“.
