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.

Researchers at Finland's Rokua National Park Discover New Species of Tardigrade

New species of tardigrade named Macrobiotus naginae was discovered by researchers at Finland's Rokua National Park.
The new species was named Macrobiotus naginae, after Nagini – the fictional snake character from Harry Potter books. It was found at the Rokua National Park in Finland's North Ostrobothnia region.
It was found to subsist in a dune woodland on lichen and moss. This habitat is currently threatened because of human activities. The new species is the fifth known member of the Macrobiotus pseudohufelandi complex, a small group of tardigrades having smaller legs and claws for living underground. They developed smaller limbs to effectively crawl through sand or soil.
The Rokua National Park is a UNESCO global geopark in Finland. It is one of Finland's oldest national parks. It was established in 1956 to protect the natural-state of lichen heaths and the unique geological features of the region.

United Nation Approves Loss and Damage Fund

The United Nation's COP27 climate summit in November 2022 approved the creation of the "Loss and Damage" Fund to compensate economically vulnerable countries for the damages caused by climate-linked disasters.
The Loss and Damage Fund is a special fund established to provide compensation to vulnerable countries for the damages they suffered because of global warming. Its aim is to unlock a greater ambition to mitigate and adapt to climate change.
"Loss and Damage" is the term that is used to refer to the cost being incurred from climate-induced weather extremes or impacts like rising sea levels.
Till date, climate funding mostly focused on reducing carbon dioxide emissions and addressing global warming. A third of this funding supported communities to adapt to climate change consequences.

Black-Naped Pheasant-Pigeon Rediscovered After 140 Years

Black-Naped Pheasant-Pigeon was rediscovered after 140 years by a research team that was part of The Search for Lost Birds – a collaboration between BirdLife International, Rewild, and American Bird Conservancy.
The objective of the collaborative initiative is to rediscover bird species that have not been declared as extinct but has not been sighted for more than a decade. Currently, there are 150 such species that has remained elusive for more than 10 years.
Before the recent rediscovery, Black-Naped Pheasant-Pigeon was first and last seen in 1882. It is a large, terrestrial pigeon having black and orange feathers and red eyes. It feeds on seeds and fallen fruits. The species is endemic to Fergusson Island in Papua New Guinea.
The population is dwindling because of the loss of forest habitats, which is caused by the logging and conversion for subsistence agriculture gardens. Conservation activities of the species' habitat are few and far between.
