हिमालय में बर्फ पिघलने से अरब सागर में जहरीला ‘नोक्टिलुका सिंटिलैंस’ शैवाल की बहार

अमेरिकी अंतरिक्ष एजेंसी ‘नासा’ के उपग्रह से लिए गए तस्वीरों में अरब सागर के तटों पर ‘नोक्टिलुका सिंटिलैंस’, जिसे ‘सी-स्पार्कल’ भी कहा जाता है, की बहार देखी गई है। इन्हीं चित्रों के आधार पर एक अमेरिकी शोध प्रकाशित हुआ है जिसमें ‘नोक्टिलुका सिंटिलैंस बहार’ (Noctiluca scintillans blooms) को जलवायु परिवर्तन की वजह से हिमालय में […]

Global Warming and Impacts of Glacial Meltdowns on Indian Rivers

Other the polar regions, the Himalayas follow as the largest deposit of frozen water in the world, especially in the case of Himalayan glaciers. Himalayan glaciers make up about 17 per cent of the Himalayas and about 37 per cent of the Karakoram Range. The water melted from Himalayan glaciers form the headwaters for many […]

On Thin Ice: Arctic, Antarctic and the Himalayas

The melting of snow in the Arctic and Antarctic due to global warming and climate change is reported frequently. However, the melting of the Himalayan glaciers goes largely unreported, even though more people are impacted. Anomalies in temperatures, global cryosphere and sea level rise are the driving factors for negative impact on global conveyor belt […]

Ozone Column in India

The stratosphere, a region above the weather producing layer—troposphere contains around 90 per cent of the earth’s ozone. Depletion of this stratospheric ozone leads to deleterious environmental effects, thus necessitating continuous monitoring. The ozone column above the Indian subcontinent has been examined since 1970 and measurements show that although the total ozone content has not […]
