Global Methane Tracker 2026:
~610 Mt methane emissions across all sources. Energy, agriculture, waste and other sectors each tell a different story, while methane tracking, satellites and rapid abatement can turn better data into faster climate action

Can latitude shape the future of renewable energy?
From the Hadley, Ferrel & Polar cells to solar, wind, hydro, storage and green fuels—this poster explores how geography, climate and ecosystems can guide region-specific renewable-energy pathways.
And explore the energy map of the future.

If you're from West Bengal/NE India and told you have "low platelets" — pause before panicking. A benign inherited trait (Harris Platelet Syndrome) causes big, healthy platelets that machines undercount. Ask for a manual blood smear, especially during dengue season.

Earth is not meaningfully shrinking.
The bigger story is energy accumulation and mass redistribution—driving ocean warming, sea-level rise and measurable changes in Earth’s rotation.
Climate change is a coupled mass–energy–angular-momentum problem.

Subglacial water pressure is a glacier’s silent killer—when pore pressure ≈ normal stress, friction vanishes, beds detach, collapse looms. Monitoring now blends radar, micro‑seismic arrays & turbidity sensors with Critical Slowing Down signals to flag failure early

El Niño signal in two points:
🌡️ 120° W — SSTA +4.3 °C, weak eastward flow.
🌡️ 171° W — SSTA +1.3 °C, stronger eastward flow.
➡️ Together: eastward heat surge, hallmark of El Niño.
🌡️ 120° W — SSTA +4.3 °C, weak eastward flow.
🌡️ 171° W — SSTA +1.3 °C, stronger eastward flow.

This poster translates Earth's energy imbalance from W m⁻² → TW → ZJ/year → ocean/land/cryosphere/atmosphere → temperature change.
It highlights a crucial distinction: EEI is not directly equivalent to surface warming.
The goal: make Earth's energy budget understandable

Very Strong El Niño 2026–27
El Niño may intensify climate extremes, but impacts will vary regionally.
In India, ENSO × IOD × Monsoon × Bay of Bengal × Arabian Sea × Jet Streams shape drought, heat and extreme rainfall. Current East India flooding shows: El Niño ≠ drought everywhere.

The data: AI adoption hit 88% of firms in 2025. But the same year, MIT found 95% of AI pilots delivered no measurable ROI. The gap isn't the technology. It's what we build around it.

Every country teaches its kids a flattering story about its own past. The real question isn't which story — it's whether we teach how we know it's true.
