The 2024 Antarctica heat wave refers to a prolonged and significant mid-winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above average. The heat wave was significant for occurring during ...
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
Even this vast and isolated ‘wilderness’ is being affected by climate change.
Antarctica may have up to 17,000 species; [108] while 90% of the ocean around Antarctica is deeper than 1,000 m (3,281 ft), only 30% of the benthic-sample locations were taken at that depth. [109] On the Antarctic continental shelves , bethnic-zone biomass may increase due to oceanic warming, which is likely to be of most benefit to seaweed .
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt—around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice—the seas would rise by over 60 m (200 ft). [22]
Churchill, Canada — Here on the edge of the Arctic in northern Canada, the annual migration of polar bears draws tourists, photographers and scientists like Geoff York. Buggies traverse the ...
About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 metres (200 ft). Antarctica holds the record for the lowest measured temperature on Earth, −89.2 °C (−128.6 °F). The coastal regions can reach temperatures over 10 °C (50 °F) in the summer.
Due to its northern location within Antarctica and proximity to the coast, the temperatures moderate more than interior climates. Winters are generally cold and subzero, while summers are chilly, but regularly rise to temperatures above freezing. The average temperature for the year in Palmer Station is 28.8 °F (-1.8 °C).
