Paris - Antarctic meltwater lakes are far more common than once thought and could destabilise glaciers, potentially lifting sea levels by metres as global warming sets in, scientists said on Wednes

Growth in terrestrial gross primary production (GPP)—the amount of carbon dioxide that is ‘fixed’ into organic material through the photosynthesis of land plants—may provide a negative feedback for climate change. It remains uncertain, however, to what extent biogeochemical processes can suppress global GPP growth. As a consequence, modelling estimates of terrestrial carbon storage, and of feedbacks between the carbon cycle and climate, remain poorly constrained.

For the first time in 24 years, this report comprehensively summarizes the status — population size and population trends — of Antarctica’s five penguin species, continent-wide and in key regions. These species total at least 5.7 million breeding pairs nesting at 660 or more sites across the entire Antarctic continent.

The Strategic Plan for Biodiversity, adopted under the auspices of the Convention on Biological Diversity, provides the basis for taking effective action to curb biodiversity loss across the planet by 2020—an urgent imperative. Yet, Antarctica and the Southern Ocean, which encompass 10% of the planet’s surface, are excluded from assessments of progress against the Strategic Plan. The situation is a lost opportunity for biodiversity conservation globally. We provide such an assessment.

The continent of Antarctica officially has a new record high temperature of 63.5 degrees, scientists from the World Meteorological Organization (WMO) announced Wednesday.

With 2016 being declared as the hottest year on record, the dangers of global warming on the world loom larger than ever.

Some 14,000 km from Japan, a 33-member team is researching a wide range of issues on global warming at Showa Station, Japan’s Antarctic research center.

Environmentalists' and scientists' concern over climate change and its effects are on another level altogether.

The West Antarctic Ice Sheet is one of the largest potential sources of rising sea levels. Over the past 40 years, glaciers flowing into the Amundsen Sea sector of the ice sheet have thinned at an accelerating rate, and several numerical models suggest that unstable and irreversible retreat of the grounding line—which marks the boundary between grounded ice and floating ice shelf—is underway.

Understanding the sources and evolution of aerosols is crucial for constraining the impacts that aerosols have on a global scale. An unanswered question in atmospheric science is the source and evolution of the Antarctic aerosol population.
