World's Biggest Iceberg is Fraying at the Edges

Iceberg A68a has been imaged at high resolution for the first time in months - and it is in a ragged condition.
The world's biggest berg is riven with cracks. Battered by waves and under constant attack from warm waters, it's now shedding countless small blocks.
A68a, which broke away from Antarctica in 2017, is on a direct heading for the South Atlantic island of South Georgia.
If it grounds there in the shallows, it could cause immense problems for the British Overseas Territory's wildlife.

Caribbean Coral Reefs under Siege from Aggressive Algae

A new algal threat is taking advantage of coral's already precarious situation in the Caribbean and making it even harder for reef ecosystems to grow.
An aggressive, golden-brown, crust-like alga is rapidly overgrowing shallow reefs, taking the place of coral that was damaged by extreme storms and exacerbating the damage caused by ocean acidification, disease, pollution, and bleaching.
"This alga seems to be something of an ecological winner in our changing world," described lead author Wilson, noting that the various other threats to coral communities make them more susceptible to the algal crusts.

Rare Whale Skeleton Discovered

An almost perfectly preserved whale skeleton thought to be between 3,000 and 5,000 years old has been discovered in Thailand.
The bones were found in November some 12 km (7.5 miles) off the coast just to the west of Bangkok.
The 12 m (39ft) long skeleton is thought to be that of a Bryde's whale.
Experts hope the find might provide a window into the past, especially for research on sea levels and biodiversity.
The partially fossilised bones are a rare find, mammal researcher Marcus Chua of the National University of Singapore told the BBC.
Mammal researcher Marcus Chua of the National University of Singapore said that there are few whale subfossils in Asia, and even fewer ones are in such good condition.

Nepal, China to Announce Revised Height of Mt. Everest

Nepal and China will jointly announce the revised height of Mt Everest, the world's highest peak, probably during the upcoming visit of the Chinese Defence Minister to the Himalayan nation.
The Nepal government aimed to measure the exact height of the mountain amid debates that there might have been a change in its height due to various reasons, including the devastating earthquake of 2015.
- According to the measurement done in 1954 by Survey of India, the height of Mt. Everest is 8,848 metres.
- In 1975, Chinese surveyors measured Mt. Everest as 8,848.13 metres above sea level. A survey in 2005 found the summit's rock height at 8,844.43 metres.

India to Achieve Target of Reducing 35 pc Emissions Intensity before 2030

According to Union Environment Minister Prakash Javadekar, India will achieve its target of reducing 35 per cent emissions intensity of its GDP well before the year 2030. The minister made the remarks while signing a memorandum of understanding (MoU) with Finland to develop cooperation between the two countries in the field of environment protection and biodiversity conservation.
The MoU was signed virtually by Javadekar and Finland's Environment Minister Krista Mikkonen.
India has achieved its voluntary target of reducing emissions intensity of its GDP by 21 per cent over 2005 levels by 2020.
Emission intensity is the volume of emissions per unit of GDP.
