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.

Mass loss from the West Antarctic ice shelves and glaciers has been linked to basal melt by ocean heat flux. The Totten Ice Shelf in East Antarctica, which buttresses a marine-based ice sheet with a volume equivalent to at least 3.5 m of global sea-level rise, also experiences rapid basal melt, but the role of ocean forcing was not known because of a lack of observations near the ice shelf. Observations from the Totten calving front confirm that (0.22 ± 0.07) × 106 m3 s−1 of warm water enters the cavity through a newly discovered deep channel.

Proxy-based indicators of past climate change show that current global climate models systematically underestimate Holocene-epoch climate variability on centennial to multi-millennial timescales, with the mismatch increasing for longer periods. Proposed explanations for the discrepancy include ocean–atmosphere coupling that is too weak in models, insufficient energy cascades from smaller to larger spatial and temporal scales, or that global climate models do not consider slow climate feedbacks related to the carbon cycle or interactions between ice sheets and climate.

Ice observations recorded by Antarctic explorers about 100 years ago show that the sea ice at the South Pole has barely changed in size over the last century, scientists say.

An Indo-Norwegian project to understand the response of Antarctic ice shelves to the global warming has begun in the less-studied areas of East Antarctica, especially the Dronning Maud Land (DML),
