🔆 Lake Erie
✅It is the fourth largest of the five Great Lakes of North America.
✅It forms the boundary between Canada(Ontario) to the north and the United States to the west, south, and east.
✅The lake’s principal tributary rivers are the Detroit (carrying the discharge of Lake Huron), Huron, and Raisin rivers of Michigan etc.
✅The lake discharges at its eastern end through the Niagara River.
✅It is an important link in the Lawrence Seaway.
📍Microcystin?
✅It is a single-celled freshwater cyanobacterium that forms colonies surrounded by mucilage.
✅The genus Microcystis contains several species which often form massive blooms and which produce toxins.
✅Microcystin is a potent liver toxin and possible human carcinogen.
✅It inhibits the activities of protein phosphatase-1 and protein phosphatase-2A, which leads to disruption of the cytoskeleton network and subsequent cell death.

🔆UN talks on drought deal in Saudi
✅The UN-hosted COP16 talks in Saudi Arabia failed to produce a binding protocol on drought response.
✅While no binding deal was reached, significant progress was made toward a future global drought regime, with plans to finalise it at COP17 in 2026 in Mongolia.
✅Droughts, exacerbated by environmental destruction, cost over $300 billion annually.
By 2050, 75% of the global population is expected to be affected by drought.
✅The UNCCD emphasised the need to restore 1.5 billion hectares of land by the decade’s end, requiring $2.6 trillion in global investments.

🔳 PM Modi laid the foundation stone of India's first Green Hydrogen Hub under the National Green Hydrogen Mission near Visakhapatnam in Andhra Pradesh, which is being developed by NTPC Green Energy.
◼️The first Green Hydrogen Hub at Pudimadaka near Visakhapatnam is being set up by NTPC Green Energy Limited.
◼️The Hub will produce 1500 tonnes per day of Green Hydrogen and 7500 tonnes per day of Green Hydrogen derivatives like Green Methanol, Green Urea
◼️The hub will also include establishing 20 gigawatts of renewable energy capacities.
◼️The Green Hydrogen Hub will help in achieving the National National Green Hydrogen Mission target of 5 MMT (Million Metric Tonne) per annum of Green Hydrogen and the addition of 125 GW of renewable energy capacity by 2030.

Post-Glacial Ecosystems: A Silver Lining to Climate Change? 🌍❄️
📰 Why in News?
Glacier retreat, a clear consequence of climate change, is revealing opportunities for developing new ecosystems that could help mitigate climate change impacts, as per a global study.
🌱 Key Findings:
✅ Emerging Ecosystems: Glacier retreat gives rise to new ecosystems, capable of capturing carbon through biogeochemical processes and biomass growth.
✅ Microbial Colonization: Microorganisms like bacteria and algae are the first settlers, followed by plants (lichens, mosses, grass), enriching the soil for larger life forms.
✅ Temporary Habitats: Deglaciated areas, particularly in Himalayas and sub-polar regions, act as biodiversity hotspots and serve as refuges for cold-adapted species.
🌍 Why Are These Ecosystems Important?
✅ Biodiversity: Potential for medicinal and agricultural discoveries.
✅ Eco-Tourism: Boosts local economies while promoting conservation.
✅ Water Regulation: Post-glacial ecosystems in regions like the Himalayas help regulate water availability, affecting rivers that millions depend on.
🧊 About Glaciers:
✅ What Are They? Massive ice sheets moving under their own weight, shaping landscapes like valleys and moraines.
✅ Significance: Glaciers store 69% of the world’s freshwater and are critical for water supplies.
🌊 Impacts of Melting Glaciers:
✅ Rising Sea Levels: Causes coastal flooding and erosion.
✅ Freshwater Scarcity: Shrinking glaciers threaten future water supplies.
✅ Biodiversity Loss: Disrupts ecosystems and wildlife habitats.
✅ Economic Risks: Tourism-dependent regions, like the Himalayas, face uncertainties.
✅ Global Warming Feedback Loop: Loss of reflective glacier surfaces accelerates warming.
🌟 Way Forward:
Efforts to study, manage, and promote biodiversity in post-glacial ecosystems are vital for creating a sustainable balance between climate change mitigation and natural habitat preservation. 🌿
