Ecosystems rarely collapse without warning. Long before forests decline, lakes become polluted or coral reefs disappear, nature often shows subtle signs that its resilience is weakening. Today, scientists are using satellite observations,…

Ocean acidification is one of the least visible yet most significant consequences of climate change. As the oceans absorb increasing amounts of carbon dioxide from the atmosphere, seawater chemistry changes, making it harder for corals,…

Earth's magnetic field is an invisible force that quietly protects life every moment of every day. Generated by the movement of molten iron deep within the planet's outer core, it shields Earth from harmful solar radiation, preserves the…

A lake turning bright green may appear harmless, but it often signals a growing environmental crisis. Triggered by excessive nutrients, warming temperatures and pollution, harmful algal blooms are becoming increasingly common in freshwater…

Healthy soil is much more than the foundation for agriculture—it is one of Earth's largest natural carbon banks. Beneath every field lies a vibrant community of microbes that stores carbon, recycles nutrients and helps the soil retain…

Heavy monsoon rainfall has once again placed parts of Odisha under flood watch, reminding us that floods threaten not only homes but also agriculture, fisheries, businesses and public infrastructure. As meteorological agencies continue to…

Rainfall is far from random. From towering mountains and moisture-rich oceans to global wind patterns and local geography, multiple natural forces determine where rain falls and where it does not. As climate change disrupts these…

Freshwater is one of Earth's most limited yet essential resources, sustaining people, agriculture, industry and ecosystems alike. As climate change alters rainfall patterns, glaciers retreat, groundwater declines and pollution contaminates…

The devastating landslides and flash floods witnessed across the Himalayan states in recent years are more than natural disasters—they are human tragedies unfolding in some of India's most fragile landscapes. Triggered by extreme rainfall,…

Modern conservation is no longer limited to field surveys and camera traps. Today, satellites orbiting hundreds of kilometres above the Earth are helping scientists monitor forests, track wildlife, map wetlands and detect environmental…
