  Deccan Trap lava hills in Western Ghats (Left) and columnar basaltic lavas (Right) which erupted 66 million years back killing dinosaurs and most life on earth. A team of scientists from IIT Kharagpur and Academia Sinica, Taipei have indeed found evidence of triple oxygen isotopes of intertrappean fossil woods that led to very high annual rainfall during the catastrophic volcanism of Deccan trap that erupted in India about 66 million years back. The eruption drove a major mass extinction killing nearly 80% of all species of animals including the Dinosaurs. The depleted values of the oxygen isotopes suggest a…

IIT Kharagpur Study Predicts River Basin-wise Agricultural Droughts-North India Shows High Vulnerability

IIT Kharagpur Study Predicts River Basin-wise Agricultural Droughts-North India Shows High Vulnerability

In-Depth, , , , ,
With inputs from Rituparna Chakraborty Highlights: The study predicts future status climate change-induced agricultural droughts across India. More intense droughts in North, North-East and Central India are expected as compared to South India. About 20 and 50% of the area in India is expected to face extreme and moderate agricultural droughts, respectively, by the end of the 21st century. Farmers in India’s north, north-east and central regions may have to be more cautious of agricultural droughts in the future - reveals IIT Kharagpur study. The data shows a geographically contrasting change in future drought patterns that indicates more intense agricultural…

Climate Change Signals from North-Eastern India, the Wettest Place on Earth

Climate Change Signals from North-Eastern India, the Wettest Place on Earth

In-Depth, , , , , ,
In a recent study, researchers from IIT Kharagpur have observed a significant change in the rainfall in the northeast in general and specifically at the wettest place on Earth, Cherrapunji-Mawsynram. The researchers observed rainfall changes in the past century (1901–2019) over the wettest place on the Earth and unveiled the first evidence for the signals of climate change and anthropogenic influence on rainfall changes in the region. The analysis of 119 years of rainfall data at 17 stations in Northeast India revealed that most of the stations show negative trends in rainfall, the highest in the summer monsoon and the…

New Indian Monsoon Rainfall Prediction Model Developed by IIT KGP Researchers

New Indian Monsoon Rainfall Prediction Model Developed by IIT KGP Researchers

In-Depth, , , , , ,
Business Standard     Financial Express      Millenium Post     Prabhat Khabar     The Week     Outlook Researchers from Centre for Oceans, Rivers, Atmosphere and Land Sciences (CORAL) of IIT KGP have developed a new statistical model, which can be used to predict variability and trends in rainfall over different climate regions of India taking into consideration both local and remote factors causing weather change. Many of these, local and remote, factors that affect weather conditions have been known to the scientific community. However, most weather forecast models typically consider local factors or a single factor that affects rainfall or…
