The Big Picture
IE Explained: Blood Moon tonight: What is it, how to watch, why you should care, in 5 points
Syllabus: Pre/Mains – Geography
Why in News?
Total lunar eclipse (Blood Moon) occurred on September 7–8, 2025, offering a rare, long 82-minute totality visible across India and much of the Eastern Hemisphere.
What is a lunar eclipse?
- Earth aligned between Sun & Moon
- Moon passed through Earth’s umbra (darkest shadow) → total eclipse
- Safe to watch with naked eye, unlike solar eclipse
What makes it a Blood Moon?
- Sunlight filtered through Earth’s atmosphere
- Rayleigh scattering: blue light scattered away, red/orange reach the Moon
- Atmosphere’s dust/pollution makes hue deeper red
Eclipse timeline (India, IST)
- Penumbral begins ~ 8:58 PM
- Partial begins ~ 9:57 PM
- Total begins ~ 11:00 PM
- Peak (max totality) ~ 11:41 PM
- Total ends ~ 12:22 AM
- Partial ends ~ 1:25 AM; Penumbral ends ~ 2:25 AM
Why it matters?
- One of the longest totalities of the decade (~82 minutes)
- Photogenic and communal spectacle—wide public interest, no special gear needed
- Scientific insight: hue depth hints at Earth’s atmospheric conditions (e.g. volcanic ash)
- Same physics explains blue skies and red sunsets
IE Opinion: What India should do to build climate-resilient cities
Syllabus: Pre/Mains – Environment
Why in News?
The World Bank’s new report “Towards Resilient and Prosperous Cities in India” estimates Indian cities need $2.4 trillion by 2050 (rising to ~$10.9 trillion by 2070) for climate-resilient, low-carbon urban infrastructure amid escalating threats from heatwaves and flooding.
Key Themes & Subpoints
Urgent Scale & Risk
- Urban population projected to nearly double: ~480 million (2020) → ~951 million (2050), ~1.1 billion (2070)
- Over 50% of urban infrastructure for 2050 is yet to be built
- Heat: night-time urban temps are 3–4 °C hotter than rural areas
- Flood risks (pluvial, coastal, fluvial) rising; annual flood losses may grow from ~$4 billion now → ~$5 billion (2030) → $14–30 billion (2070)
- Heat-related deaths could more than double (>144 k → >328 k by 2050)
- Job generation: ~70% of new jobs by 2030 expected in cities
Investment Needs & Financing
- $2.4 trillion needed by 2050; ~$10.9 trillion by 2070 (conservative)
- Current urban infrastructure spending ≈ 7% of GDP—far below global norms
- Less than 5% of investment is from private sector
Strategic Responses
Urban design & infrastructure:
- Better storm-water regulation
- Green spaces, cool roofs, early warning systems
- Flood-resilient transport networks, resilient municipal services (water, waste)
Institutional reforms:
- Strengthen coordination across federal, state, and local levels
- Enhance autonomy of Urban Local Bodies (ULBs)
- Create dedicated urban resilience programmes, financing roadmaps
Private sector mobilization:
- Green bonds, blended finance, international climate funds
- Engage as key partners in service delivery and innovation
Impact & Opportunities
- Flood adaptation could avert ~$5 billion losses annually by 2030, ~$30 billion by 2070
- Heat mitigation measures could save ~130,000 lives and boost GDP by up to 0.4%
- Resilient cities attract investment, generate jobs, foster innovation, and build inclusive prosperity
