About IUCN red list of threatened species

  • The IUCN Red List of Threatened Species is the world’s most comprehensive inventory of the global conservation status of plant and animal species.

  • It uses a set of quantitative criteria to evaluate the extinction risk of thousands of species.

  • These criteria are relevant to most species and all regions of the world.

  • With its strong scientific base, The IUCN Red List is recognized as the most authoritative guide to the status of biological diversity.

The IUCN Red List Categories:

  • The IUCN Red List Categories define the extinction risk of species assessed. Nine categories extend from NE (Not Evaluated) to EX (Extinct).

  • Critically Endangered (CR), Endangered (EN) and Vulnerable (VU) species are considered to be threatened with extinction.

4. Stalagmite key to predicting monsoon patterns: Study

An unusual cave in Meghalaya has helped unlock secrets about climate change, according to scientists who say that data from stalagmites in India could help better predict monsoon patterns, droughts and floods in the country.

About the study

  • The study found an unexpected connection between winter rainfall amounts in northeast India and climatic conditions in the Pacific Ocean.

  • Winter rainfall following weak monsoon years in India can alleviate water stress for farmers. This distant link between land and ocean records could aid in predicting dry season rainfall amounts in northeast India.

  • Each year, monsoon rains between June and September provide water for roughly 1.5 billion people in India.

  • Changes in monsoon strength and the timing of its onset or withdrawal can trigger either drought or flooding, with devastating consequences, highlighting the need for effective ways to predict and prepare for rainfall variations.

  • Stalagmites from Mawmluh Cave and the surrounding region indicate the recurrence of intense, multiyear droughts in India over the last several thousand years.

Stalactite and Stalagmite

  • The water containing limestone in solution, seeps through the roof in the form of a continuous chain of drops.

  • A portion of the roof hangs on the roof and on evaporation of water, a small deposit of limestone is left behind contributing to the formation of a stalactite, growing downwards from the roof.

  • The remaining portion of the drop falls to the floor. This also evaporates, leaving behind a small deposit of limestone aiding the formation of a stalagmite, thicker and flatter, rising upwards from the floor.

  • Sometimes, stalactite and stalagmite join together to form a complete pillar known as the column.

  • Taking on the title will be the sleepy village of Tashigang, situated in the Buddhist dominated district - it also holds the title of being the highest village in the Spiti Valley.  

  • The Election Commission has set up a new polling station there, which is nearly 690 feet above the one in Hikkim (14,567 feet), making the Tashigang polling station (15,256) not just the highest in the country but in the world.
