The 2025 Global Report on Food Crises indicates that over 295 million people across 53 countries experienced acute hunger in 2024, marking a sixth consecutive year of rising food insecurity, driven by conflict, economic shocks, and climate change. This figure represents a 13.7 million increase from 2023, with the most severe hunger concentrated in conflict-affected regions like Gaza and Sudan.

This figure represents a 13.7 million increase from 2023, with the most severe hunger concentrated in conflict-affected regions like Gaza and Sudan.  Key Findings on Global Hunger (2025 Reports): Scale: - Over 295 million people are facing high levels of acute food insecurity. Drivers: - The "lethal Cs" — conflict, climate extremes, and economic shocks/cuts — are primary drivers of this crisis. Conflict-Driven Hunger: - In places like Gaza, hunger is increasingly used as a weapon of war. 2025 Outlook: - The situation is expected to remain "bleak," with potential decreases in humanitarian funding, threatening to worsen malnutrition for millions. Future Projections: - Climate change is expected to continue exacerbating these...

Industrial activity, particularly coal-based thermal power plants, is generally considered the largest source of air pollution in India, accounting for roughly 51% of total emissions. Other major contributing sectors include vehicular emissions, agricultural crop residue burning, road dust, and residential biomass burning.

Industrial activity, particularly coal-based thermal power plants, is generally considered the largest source of air pollution in India, accounting for roughly 51% of total emissions. Other major contributing sectors include vehicular emissions, agricultural crop residue burning, road dust, and residential biomass burning.  Key contributors to India's poor air quality include: Industrial Emissions: - Coal-fired power plants and manufacturing units are the primary sources. Vehicular Pollution:-  Vehicles account for 60-70% of overall pollution in some estimates. Agricultural Crop Burning: - A major source of seasonal,, acute, smog and pollution, especially in autumn and spring. Residential Sector: - Burning of biomass (wood, dung) for cooking/heating is significant. Construction Dust & Waste Burning:-  Contributes about 45% of PM pollution.  While industrial pollution holds the largest share nationally, in metropolitan cities like Delhi, vehicular emissions and ro...

Global warming creates Rising temperatures and shifting atmospheric circulation are causing the potent greenhouse gas nitrous oxide (N2O 𝑁2𝑂) to break down faster than previously estimated, altering its chemical behavior. Studies show its atmospheric lifetime is decreasing by 1.4% per decade, introducing new uncertainties into 21st-century climate projections. Global warming affects humans by causing severe health crises, including increased heat-related deaths (up 23% since the 1990s), respiratory issues from wildfire smoke, and the spread of infectious diseases like malaria and Lyme disease. It threatens food security, causes extreme weather disasters, and disrupts livelihoods, with 3.6 billion people living in highly susceptible areas. Key Impacts on Human Health and Well-being:-Extreme Heat & Physical Health:- Rising temperatures increase heatstroke, cardiovascular disease, and mortality, particularly among the elderly and outdoor workers.Disease Spread: -Warmer conditions allow disease-carrying insects (ticks/mosquitoes) to spread into new regions, increasing cases of Dengue, West Nile virus, and Lyme disease.Respiratory and Air Quality Issues: -Increased wildfires and pollen seasons exacerbate respiratory conditions like asthma and COPD, with wildfire smoke causing over 150,000 deaths annually.

Reduced Lifetime:-  Satellite data (2004–2024) reveals the atmospheric lifetime of N2O 𝑁2𝑂 is decreasing, which impacts how long this powerful, ozone-depleting gas remains in the atmosphere. Climate Feedback Uncertainty: - While N2O𝑁2𝑂 is breaking down faster, its overall concentration continues to rise due to human activities like agriculture, creating a complex feedback...

China has constructed multiple massive, gigawatt-scale solar farms in harsh desert regions like the Talatan plateau in Qinghai and the Kubuqi Desert, transforming barren land into major clean energy hubs to meet climate goals. These projects, sometimes stretching over 2,000 square kilometers, stabilize sand dunes, promote vegetation, and use smart technology to power millions of homes.
