Indonesia on High Alert as Mount Semeru Volcano Erupts in Java

Indonesia's Mount Semeru erupted spewing hot ash clouds a mile into the sky and sending rivers of lava down its side, sparking the evacuation of nearly 2,000 people exactly one year after its last major eruption killed dozens.
The eruption of the highest mountain on Indonesia's main island of Java, around 800 kilometres (500 miles) southeast of capital Jakarta, prompted authorities to raise the alert status to the highest level.
The increased threat level means the danger has threatened the people's settlement and the volcano's activity has escalated.

Massive Glacier the Size of 10 Football Fields Breaks Down in Antarctica

Researchers on board the British Antarctic Survey's RRS James Clark Ross captured a major calving event as the William Glacier disintegrated into a thousand small pieces. William Glacier lies on the Antarctic Peninsula.
While such events have long been known to trigger tsunamis at the surface of the ocean, the calving event when analysed by the team revealed that the glacier calving can excite vigorous internal waves – a process that has been neglected in driving ocean mixing in computer models.
The William Glacier typically has one or two large calving events a year. With the front of the glacier towering 40 m above sea level, the team estimated that this event broke off around 78,000 square meters of ice.

UN Panel Recommends Great Barrier Reef be Put on 'in Danger' List

Australia's Great Barrier Reef located in Coral Sea should be listed as a world heritage site that is "in danger", a UN panel recommended, saying the world's biggest coral reef ecosystem was significantly impacted by climate change and warming of oceans.
Frequent bleaching events are threatening the reef, including four over the last seven years and the first during a La Nina phenomenon, which typically brings cooler temperatures, this year.
Bleaching happens when the water warms too much, causing corals to expel the colourful algae living in their tissues and turn white.

Mauna Loa: World's Largest Active Volcano Erupts in Hawaii

The world's largest active volcano, Hawaii's Mauna Loa, erupted for the first time in almost 40 years.
The lava flow was mostly contained within the summit, but residents were placed on alert and were earlier warned about the risk of falling ash.
The US Geological Service (USGS) said that the situation could change rapidly.
The volcano's alert level was also upgraded from an "advisory" to a "warning" - the highest classification.
Mauna Loa, located inside Hawaii Volcanoes National Park, covers half of the US state's Big Island. The volcano rises 13,679ft (4,169m) above sea level and spans an area of more than 2,000 sq miles (5,179 sq km).
It followed a series of warnings that an eruption was possible after a spate of recent earthquakes in the region, including more than a dozen reported tremors.

Leith's Soft-shell Turtle

India's proposal to increase the protection of Leith's soft-shell turtle was approved at the 19th Meeting of the Conference of the Parties (CoP 19) to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which was held in Panama City from November 14 to 25.
Leith's soft-shell turtle is a large freshwater soft-shelled turtle that is endemic to peninsular India.
It has been subject to intense exploitation over the past 30 years for poaching and illegal consumption within India. It has been illegally traded to foreign countries for meat and its calipee.
This species' population has fallen by 90 per cent over the past 3 decades and is now very difficult to find.
It is classified as "critically endangered" in the IUCN Red List.
