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 ...
By 2009, researchers were able to combine historical weather-station data with satellite measurements to create consistent temperature records going back to 1957 that demonstrated warming of >0.05 °C/decade since 1957 across the continent, with cooling in East Antarctica offset by the average temperature increase of at least 0.176 ± 0.06 °C ...
Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
While North America’s record 134° F has stood for more than a century, Antarctica and Asia have set temperature records in the past decade.
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 ...
The maximum recorded at Concordia on 17 March was -16.9 °C Pending the final data, in Vostok the value of -20.3 °C set the new monthly record but also exceeds the maximum of February (-22.2 °C ...
Record of atmospheric temperature taken from EPICA ice core in Antarctica. The Antarctic Cold Reversal ( ACR ) was a climatic event of intense atmospheric and oceanic cooling across the southern hemisphere (>40°S) between 14,700 and 13,000 years before present ( BP ) that interrupted the most recent deglacial climate warming (c. 18,000-11,500 ...
The picture shows delta deuterium data (a proxy for temperature: more negative values indicate lower temperatures) from both EPICA and Vostok. The upper plot, with x-axis being age (years before 1950) clearly shows the extra information in the EPICA core before the start of the Vostok record. The lower picture, plotted against depth, shows how ...
