Climate change stunting moss growth

From the the January issue of Global Change Biology comes this story about the dominant plant species in Antarctica–moss. There aren’t many warm spots on the continent, but in a few coastal “oases”  beds of moss grow during the short ice free summers.  The dominant species is Ceratodon purpureus, and it is fed by melt […]

Antarctica’s mystery mountain range

What mountain range is as high and long as the European Alps, but has never been seen by human eyes? The Gamburtsev Mountains in East Antarctica were discovered in 1958 by the third Soviet Antarctic expedition, but no one has ever seen them.  They are covered with over 600 meters of snow and ice. It […]

Mertz Glacier calving leads to reduced sea ice

Mertz, a heavily crevassed glacier in George V Land of east Antarctica, has a tongue that protrudes 100km into the Southern Ocean.  In February, 2010 it split in half due to the collision with iceberg B9-B, which had broken off the Ross Ice Shelf in 1987.  The newly formed iceberg was called Iceberg C-28.  (It was […]

Octupus genome gives a clue about ice shelf collapse

The West Antarctic Ice Shelf is the largest and most unstable of the world’s ice sheets, and some climate scientists believe it could be capable of a relatively quick collapse causing a catastrophic rise in sea levels. These Turquet’s octopuses will certainly be saying “I told you so.” Although you wouldn’t, on first analysis, see […]

Albatrosses breeding early

  One of the largest birds in the world has begun to breed earlier in the season.  In a study published in Oikos, researchers stated that the wandering albatross had begun laying its eggs an average of 2.2 days sooner than in the past 30 years.  Although climate change may be to blame, the scientists […]

“Back to the Bad News” or “How Fox Makes Sh*t Up”

Today I want to tell you about the media’s reporting of a paper, published in Earth and Planetary Science Letters, by Professor Zunli Lu of Syracuse University. The study, “An ikaite record of late Holocene climate at the Antarctic Peninsula,” finds that ikaite crystals have a useful property for studying past climactic conditions.  The crystals […]

Good News!

Normally we get only bad news about the environment so I thought I would report about a hopeful story I read in the Calgary Herald.  Using satellite mapping technology, a group of British Antarctic Survey scientists has found that there are more than twice the number of Emperor penguins (Aptenodytes forsteriis) on the frozen continent than previously […]

Polenet

In an effort to find out what is happening under the West Antarctic ice sheet, scientists have installed a network of seismographs, appropriately called “Polenet.”  The brutal conditions have made such research difficult in the past, as delicate equipment normally only lasts a few months.  But improvements in battery life and data storage mean the […]

Antarctic bottom water reduced

You might not have heard of Antarctic bottom water, but according to this article it is declining.  Why would that matter?  Well first of all we had better check page 5 of the Google results to find out just what Antarctic bottom water is! The Free Dictionary (Acronyms division) helpfully tells us that Antarctic Bottom […]

Bahamas offers clue to height of seas by 2100

As reported in the Science Daily News from the journal Nature comes the report that by pinpointing where ancient shorelines stood in the Bahamas and Bermuda researchers hope to be able to predict future rises in sea level. In an exceptionally warm period 400,000 years ago, seas rose 20 feet, up to a third less […]
