			<description><![CDATA[Climate warming and short-term climate variability have pushed a number of massive glaciers in Greenland towards retreat, which has some scientists concerned that the retreat may be irreversible once it has begun. However research published in Geophysical Research Letters suggests that Greenland glaciers&rsquo; rapid ice loss may not be an entirely irreversible phenomenon.]]></description>

As temperatures rise, scientists worldwide are concerned about the possible consequences of a massive release of carbon from the soils thawing permafrost into the atmosphere might have on the carbon cycle. They believe microbes living in the soil might have the largest impact.]]></description>

During the Archaen eon, between 4 and 2.5 billion years ago, these volcanoes are thought to have provided the building blocks for the formation of the first biomolecules and ideal conditions for the formation of life. It is the first time that an environment meeting all the requirements needed for life to emerge has been identified in 3.8 billion year-old rock formations.]]></description>

			<description><![CDATA[An international team of researchers recently published findings in the journal Limnology and Oceanography showing that Antarctic krill (Euphausia superba) &ndash; a shrimp-like creature at the core of the Antarctic food web &ndash; could play a key role in fertilising the Southern Ocean with iron. Iron is a micronutrient that stimulates the growth of phytoplankton (microscopic plant-like organisms at the base of the Antarctic food chain), which store atmospheric carbon dioxide in their bodies as they grow and bloom.]]></description>

A growing cavity under the ice shelf has allowed more warm melting ice, which contributes to sea level rise.

			<description><![CDATA[A report recently issued by the Pontifical Academy of Sciences lists various examples of  glacial decline around the world and the evidence linking the decline to  man-made climate change. According to the report, entitled "Fate of  Mountain Glaciers in the Anthropocene", the changes observed in mountain  glaciers result from a &ldquo;complex mix of causal factors that include  greenhouse gas forcing together with large scale emissions of dark soot  particles and dust in 'brown clouds', and the associated changes in  regional atmospheric energy and moisture content [&hellip;]".]]></description>

			<title>New Study Highlights Wide-Ranging Impacts of Climate Change in Arctic</title>
			<link>http://www.sciencepoles.org/news/news_detail/new_study_highlights_wide-randing_impacts_of_climate_change_in_arctic</link>
			<description><![CDATA[With the most   recent five-year period having been the warmest since 1880 when monitoring   began, climate change is predicted to bring a wide range of impacts to the Arctic, according to a new report entitled Snow, Water, Ice, Permafrost in the Arctic (SWIPA). The report was coordinated by the  Arctic Monitoring and Assessment Programme (AMAP) and produced in collaboration with the International Arctic Science  Committee (IASC), the World Meteorological Organization (WMO), the  Climate and Cryosphere program (CliC) and the International Arctic  Social Sciences Association (IASSA).]]></description>

			<title>Climate Change Might Be Too Much for Siberia&#8217;s Boreal Forests</title>
			<link>http://www.sciencepoles.org/news/news_detail/climate_change_might_be_too_much_for_siberias_boreal_forests</link>
			<description><![CDATA[According to a study recently published in the Environmental Research  Letters by researchers from Nagoya University in Japan, the larch trees  dominating the boreal forest of Siberia might not survive even the most  optimistic climate change scenario of a 4&deg;C increase in summer  temperature in Siberia by the year 2100. The team found that trees  manage to survive in the semi-arid climate due to a symbiotic  relationship they have built with the permafrost. Ironically, this  relationship is also what makes the system sensitive to climate change.]]></description>

			<description><![CDATA[According to a new study presented at the Greenhouse 2011 Conference in  Cairns, Australia in April, warming oceans could release carbon dioxide (CO2)  dissolved in the water into the atmosphere, further adding to the  greenhouse effect.]]></description>
