The natural El Nino cycle, which warps weather worldwide, is both adding to and shaped by a warming world, meteorologists said. A new study calculated that an unusual recent twist in the warming and cooling cycle that includes El Nino and its counterpart La Nina can help explain the scientific mystery of why earth’s already...

The story so far: The National Green Tribunal (NGT) recently concluded a high-stakes legal battle over the ‘Holistic Development of Great Nicobar Island’, and ruled that all environment safeguards are in place for the Great Nicobar Island Project.

India is among just four countries that contribute almost 70% to the world’s total applied toxicity (TAT) in the form of pesticide, which is directed at agricultural pests, but in affect unleashes huge collateral damage among “non-target” species (that is, species that pesticides claimed as collateral). In 2022, at the United Nations Biodiversity Conference, countries...

The official theme of LGBTQ+ History Month (February) this year is ‘Science & Innovation’ and the natural universe is replete with examples of how the simple binary of sexes and genders to which some people would...

Humans have climbed to the top of the food chain by skillfully hunting, trapping, and fishing for other animals at scales that far exceed other predators, altering how the animals behave and earning the tag of a “super-predator”. But a new study led by the Centre for Ecological Sciences, Indian Institute of Science (IISc), suggests...

The spectre of climate change has come to haunt one of the ocean’s most ubiquitous — yet vulnerable — turtles: the strong-jawed loggerhead, named after its exceptionally large head. These omnivorous marine reptiles have been impacted in at least four ways by global warming. As the ocean warms and marine produce dwindle, these turtles are nesting earlier in the year, and more worryingly, they are producing...

The colours of the natural world are not what they once were. More than half of the oceans have become greener over the last 20 years, and forests are turning brown prematurely. Various species of flora and fauna have also been changing their colours to adapt to rising temperatures, loss of habitats, and pollution. This...

GUWAHATI: A team of researchers from the Indian Institute of Technology Guwahati (IIT-G) has developed a new way to identify where glacial lakes are likely to form in the Himalayas, offering a potential breakthrough in disaster preparedness for mountain regions facing rapid climate change. Their study focuses on the Eastern Himalayas, which has recorded the...
