Climate change

Hidden beneath the Atlantic Ocean lies one of Earth's most powerful climate engines—the Atlantic Meridional Overturning Circulation (AMOC). This vast network of ocean currents transports heat, regulates rainfall and supports marine…

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,…

Across Odisha, rising water levels in the Mahanadi, Baitarani and other major rivers have transformed the monsoon from a season of hope into one of uncertainty. As villages, farmlands and even riverside temples face inundation, thousands of…

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…

The Butterfly Effect reveals how small changes can produce surprisingly large consequences in complex systems like Earth's atmosphere. While a butterfly's wings do not literally create storms, the concept explains why weather is difficult…

Weather forecasts may seem simple, but they are the result of an extraordinary scientific process. By combining data from satellites, weather balloons, radar systems, aircraft and ground stations with powerful supercomputers and advanced…

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…

Every animal leaves behind tiny traces of its DNA in water, soil and even the air. Scientists are now using this invisible genetic fingerprint—known as environmental DNA (eDNA)—to monitor wildlife without disturbing it. From detecting…

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,…

Rain is often seen as nature's purest gift, washing the air and breathing life into rivers, forests and farmland. Yet modern science reveals a more complex reality. As raindrops fall through the atmosphere, they collect pollutants ranging…
