Decoding the Mysterious Origins of Baobab Trees
Recent genomic research suggests that baobabs originated in Madagascar and later dispersed to Africa and Australia. Factors like climate and sea level changes influenced their evolution. Rising sea levels threaten their expansion, necessitating urgent conservation.…

🔆National Endangered Species Day
✅Recently, the National Endangered Species Day was celebrated across the world.
📍 National Endangered Species Day:
✅It is observed to create awareness about the consequences of human activities and what we can do to save endangered species.
Every year, National Endangered Species Day is observed on the third Friday of the month of May.
📍History
✅In the year 2006, David Robinson and the Endangered Species Coalition established National Endangered Species Day to be celebrated every year to urge people to contribute to the safety and protection of endangered species.
✅According to the International Union for Conservation of Nature, forty percent of animals, insects and plants on this planet are at risk of extinction.
✅The theme for the year 2024: Celebrate Saving Species.
📍Significance
✅The day promotes conservation efforts and encourages individuals and organisations to participate in activities that help protect endangered species.
✅This includes habitat restoration, supporting conservation laws, and advocating for stronger environmental policies.

🔆Humboldt glacier in news
Venezuela is likely become the first country in modern history to loose all its glaciers.
Humboldt the glacier of Venezula has shrunk to an area of less than 2 meter
📍Why glacier loss matters?
✅Glaciers are the largest fresh water sources
✅Cold glacier runoffs keep downstream water cooler, key to survival of many aquatics species
✅Glaciers are main source of perennial rivers
✅Melting of glacier can contribute to rise in sea levels

🔆Flash -Drought in News
✅ Flash droughts are those that occur very quickly, with soil moisture depleting rapidly.
✅Normally, developing drought conditions take months, but these happen within a week or in two weeks’ time.
✅ Several factors including atmospheric anomalies, anthropogenic greenhouse gas emissions play an important role.
✅ It is widely believed that flash droughts will occur during the summer months as was reported in the Western countries, mostly driven by heat waves and very high temperature. But in India, 82 per cent of such extreme weather events happen during the monsoon period.

🔆Sathyamangalam Tiger Reserve
✅The Tamil Nadu Forest Department recently commenced a three-day-long elephant census at Sathyamangalam Tiger Reserve.
✅It is located at the junction of the Eastern and Western Ghatsin the Nilgiri Biosphere Reserve, in the Erode District of Tamil Nadu.
✅Its area is contiguous with the Mudumalai Tiger Reserve, Bandipur Tiger Reserve (Karnataka), and Biligiri Rangaswamy Temple Tiger Reserve and Wildlife Sanctuary (Karnataka). Together, these reserves—forming the Nilgiris biosphere landscape— have the biggest tiger population in the world, at over 280 tigers.
✅It was declared a tiger reserve in 2013. It forms a vital link between the Eastern and Western Ghats, creating a continuous habitat for tigers and other wildlife.
📍Climate:
✅It is subtropical and dry.
✅The summers are hot and dry; the monsoons are wet and cooler, with river flooding.
✅Rivers: Some of the prominent rivers in the region include the Bhavani, Moyar, and Noyyal rivers.
✅Tribal Communities: It is home to several indigenous tribal communities, including the Irula and Kurumba tribes.
✅The major species are Elephant, Tiger, Panther, Sloth bear, Gaur, Black Buck, Spotted deer, Wild boar, Black napped hare, Common langur, Striped neck mongoose, and Bonnet macaque.
✅It is home to some rare and endangered species, such as the grizzled giant squirrel, the Nilgiri tahr, the Nilgiri langur, and the four-horned antelope.

🔆Research Shows Sun’s Magnetic Field Originates Closer to Surface
Recent studies and observations have shown that solar activity, especially solar storms, can have huge effects on Earth. Earth was hit by strong solar storms earlier this month, which included coronal mass ejections (CMEs) and strong solar flares. These storms caused beautiful auroras and problems with power and communication systems.
📍Understanding the Sun’s Magnetic Field
According to a new study from an international team, the sun’s magnetic field is created much closer to the surface than was thought before. They say it’s about 20,000 miles .
What is the Solar Dynamo Process?
The method by which the sun’s magnetic field is made is called the solar dynamo. It is a complicated system where the sun’s magnetic field and the moving of plasma work together. This plasma flow changes with location and changes about every 11 years during the solar cycle.
Impact on the Heliosphere and Earth:
The heliosphere, the bubble-like area of space dominated by the solar wind, is greatly affected by the action of the solar dynamo. The heliosphere gets smaller when the sun isn’t active, which changes the flow of cosmic rays and the weather in space that affects Earth. These changes could affect how satellites work, how information systems work, and even how the weather works on Earth.
