■ KINNAUR HYDRO ELECTRICITY PROJECT

#Infrastructure

The people of Kinnaur, Himachal Pradesh have been protesting against the proposed 804-megawatt Jangi Thopan Powari hydroelectricity project (JTP HEP) over the Satluj since April 2021.

□ ABOUT PROJECT :-

◇ Project envisages the construction of a concrete gravity dam of metres high above the deepest foundation level across river Satluj near Jangi village.

◇ The diversion of water will involve the construction of a 12-km-long tunnel.

◇ Construction of the dam will result in the submergence of about 156.2917 ha of land, out of which 143.2093 ha is forest land and 13.0824 ha is private.

□ WHY PEOPLE PROTESTING ?

◇ The river has been dammed at multiple places along the valley to create an additional feature to Kinnaur’s identity as Himachal’s hydropower hub, which locals believe is a malediction.

■ A - 76 ICEBEG

#Climatechange

A huge ice block has broken off from western Antarctica into the Weddell Sea, becoming the largest iceberg in the world and earning the name A-76.

□ ABOUT :-

◇ A-76 is the latest in a series of large ice blocks to dislodge in a region acutely vulnerable to climate change, although scientists said in this case it appeared to be part of a natural polar cycle.

◇ The iceberg, measuring around 170 km long and 25 km wide, with an area of 4,320 sq km is now floating in the Weddell Sea.

◇ Slightly larger than the Spanish island of Majorca, A-76 had been monitored by scientists since it began to separate from the Ronne Ice Shelf.

◇ It joins the previous world’s largest title holder A-23A — approximately 3,880 sq. km. in size — which has remained in the same area since 1986.

◇ Spotted by British Antarctic Survey and when an iceberg breaks off was confirmed using images from the Copernicus satellite.

■ SOUTHERN OCEAN AS FIFTH OCEAN

#Climatechange

The National Geographic magazine has recognized the ‘Southern Ocean’ as the world’s fifth ocean June 8, 2021 hoping others will soon follow suit.

□ ABOUT :-

◇ The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica.

◇ As such, it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean.

◇ Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem.

□ What has NatGeo attempted ?

◇ The magazine says the Southern Ocean is the only ocean ‘to touch three other oceans and to completely embrace a continent rather than being embraced by them’.
