Oceans Current Affairs - 2020
The World Meteorological Organization announced that for the first time in record Antarctica has recorded its hottest temperature ever, 20.75 Degree Celsius. So far, the highest was 18.3 Degrees Celsius that was recorded in January 1982.
The higher temperatures were influenced by shifts in El Nino and Ocean Currents. According to United Nations scientists, the Antarctic region stores more than 70% of world’s fresh water. If it melts, the sea level will increase by 50 to 60 metres.
Significance of Ice Sheet in Antarctica
The ice sheet in Antarctica covers 14 million square kilometres. To the east of Antarctica there lies land masses under the ice sheets. However, on the west Antarctica the ice beds can extend to more than 2500 metres under the sea.
The Arctic and Antarctic Ice sheets are important as they reflect 80% to 90% of solar radiation. On the other hand, the other dark surfaced landforms reflect less solar radiation and retain great amount of heat.

A yearbook was launched that called on the governments to strengthen the UNFCCC agenda post 2020. It also insisted to create actions for a climate resilient world between 2020 and 2050.
Report on Oceans
The conference also released report on oceans titled “Special Report on the Ocean and Cryosphere in a Changing Climate” (SPROCC). According to the report, global mean sea level increased from 1.4 mm (1901-1990) to 3.6 mm (2006-2015). Also, the report says that the ocean warming has increased since 1993. Between 1993 and 2017, 700 to 2000 metres of ocean layers have warmed up.
Nairobi Work Programme
The Nairobi Work Programme was reviewed and its progress were discussed at the conference. The Programme was established in 2005 at COP11. It aims at impacts, adaptation and vulnerability to climate change.
The objective of the programme is to assist least developed countries to understand and assess impacts of climate change.
The Global Climate Risk Index 2020 was published at the conference
