Remote Sensing Data Indicate A -2.44ºC Summer Cooling For Antarctica Sea Ice Regions During 1982-2015
By Kenneth Richard on 27. May 2019
A new paper published in Remote Sensing reports substantial summer cooling of Antarctica’s entire sea ice region due to an increase in surface albedo between 1982 to 2015.

The Characteristics of Surface Albedo Change
Trends over the Antarctic Sea Ice Region
during Recent Decades
“The Arctic sea ice is becoming thin and young, whereas the sea ice extent in Antarctica has slightly increased over the last four decades. Parkinson et al. (2012) used satellite passive–microwave data and found a substantial increasing trend (17100 ± 2300 km2 year−1) of sea ice extent over Antarctica from 1978 to 2010. Turner et al. (2016) determined an increasing trend by 195 × 103 km2 per decade for the total Antarctic sea ice extent from 1979 to 2013. Then, the satellite-derived sea ice extent during 1979 to 2015 was studied by Jena et al. (2018) who declared that the increasing trend of sea ice extent in the Indian Ocean was about 2.4 ± 1.2% per decade. Thus, understanding the changes in sea ice in the Antarctic sea ice region (ASIR) is essential to global climate research.â€
