Rapid krill decline: 80% over 35 years

Posted on April 13, 2011 by Rolf Schuttenhelm

Antarctica does not escape the Holocene Mass Extinction. Krill numbers have dropped sharply since the mid-70s and as a consequence penguins too are in decline, says new study in Monday’s edition of PNAS, that blames the ecological disturbances on climate … Continue reading →

Arctic update: 2011 indeed lowest winter ice extent

Posted on April 10, 2011 by Rolf Schuttenhelm

The Arctic sea ice maximum of the winter of 2010-2011 is the lowest ever recorded.

2011 lowest ice maximum remains uncertain – Arctic April makes cold start

A bit of green on Antarctica to aid against global warming

Posted on March 2, 2011 by Jorn van Dooren

Brilliant green pools teeming with life have been found among remote Antarctic sea ice. The pools owe their colour to the high amounts of algae in the water. The pools were observed in the Amundsen Sea’s polynya, a region of seasonally … Continue reading →

Arctic sea ice attacked from two sides

Posted on February 2, 2011 by Rolf Schuttenhelm

Climate change is not only causing the Arctic sea ice to melt because it heats the atmosphere above it, but also through heat advection, by warming ocean currents that make contact with the ice.

Snowball Earth was partly sleet

Posted on January 13, 2011 by Stefan Engels

Sedimentary structures encountered in South Australian rocks indicate that parts of the sea in which they were formed were open, and therefore unfrozen, during at least part of the Cryogenian, or ‘Snowball Earth’.

GCM study finds no Arctic albedo tipping point

Posted on December 20, 2010 by Rolf Schuttenhelm

The albedo effect still acts as a positive feedback to warming and melting. In fact the general circulation model study shows Arctic sea ice melting will speed up over recent years. From 2020 to 2030 more than 2.5 million square … Continue reading →

Autumn 2010 Arctic sea ice lowest ever

Posted on December 2, 2010 by Rolf Schuttenhelm

Short news, but relevant to a possible temperature record for 2010 and to spicing up the current UN climate negotiations in Cancún:

Arctic melting record 2010: one third gone

Posted on September 29, 2010 by Rolf Schuttenhelm

With October in sight, and NOAA predicting a positive phase for the Arctic Oscillation, winter returns to the North Pole. That means, after some prolonged melting in the second half of September, the yearly minimum in the Arctic sea ice … Continue reading →

Arctic late to reach annual low

Posted on September 24, 2010 by Rolf Schuttenhelm

The sea ice in the Arctic Ocean is late to reach its yearly minimum. Daily satellite measurements show that after a small recovery with some net expanding, melting continued through the second half of September. Usually around this time of … Continue reading →
