1.) From Agence France-Presse, "Antarctic ice shelf collapse linked to global warming":
The collapse of a huge ice shelf in Antarctica in 2002 has no precedent in the past 11,000 years, a study that points the finger at global warming says.2.) From SomaliNet (via our distinguished colleague Susie Madrak), "Snowfall in Somalia Reported":
Measuring some 3,250 square kilometres in area and 220 metres thick, the Larsen B iceshelf broke away from the eastern Antarctic Peninsula in 2002, eventually disintegrating into giant icebergs.
By chance, a US-led team of geologists had gathered a rich harvest of data around the iceshelf just before the spectacular collapse, including six cores that had been drilled into marine sediment.
The cores contain the remains of plankton and algae embedded in layers of minerals, and their radiocarbon and oxygen isotopes provide clues about ice cover and climate change over the millennia.
The researchers, reporting in the British science weekly Nature, say since the end of the last Ice Age, some 11,000 years ago, the iceshelf had been intact but had slowly thinned, by several dozen metres.
Its coup de grace came from a recent but decades-long rise in air temperature, they say. "The modern collapse of the LIS-B 1/8Larsen B iceshelf3/8 is a unique event within the Holocene," they write.
The first snowfall on this part of the world has claimed one life and caused extensive damage to properties. Puntland, northeastern part of Somalia has never recorded snowfall before last night when snow storms with high winds destroyed homes in Rako town.
The storm left a blanket of snow on the ground, something residents had never seen in their lives before. Aside from this unexplained snowfall on this tropical land, Somalia has experienced very strange weather in the past few months.
Floods killed people and forced rivers to overflow banks in almost all parts of the country. Many cities from Hargeisa in the north to Baladweyn in central were affected badly by heavy rains and floods. Many people were killed and thousands of livestock washed away by this strange weather.
