Climate Model Successfully Predicts Arabian Sea Cyclones

The successful prediction of the recent cyclones in the Arabian Sea by Princeton University researchers along with the NOAA using climate models with temperature rise and atmospheric pollutants as variables raises poignant questions over climate change.

Vaishno Devi Pilgrimage Resumes after Fire in Trikuta Hills

Devotees on pilgrimage in the Vaishno Devi Yatra in Jammu & Kashmir were stranded after 25,000 pilgrims had registered for a trek at 3:30 pm on May 23rd, 2018 due to a forest fire in Trikuta Hills. The fire in Trikuta Hills led to the pilgrimage being suspended since the afternoon of May 23rd with 10,000 pilgrims stranded in Katra base camp and 3,000 being shifted to a safer location nearby Himkoti Marg. The shrine board on learning of the fire in Trikuta Hills suspended the Vaishno Devi Yatra...

NASA Finding throws light on Rising Global Methane Emissions

Global methane emissions have been markedly increasing in recent years, with a large contributor being emissions from the global oil and gas industry. It is estimated that methane emissions globally have been increasing by a massive 25 teragrams per year since 2007. However, a problem was posed in breaking down this number between emissions from the oil and gas industry and other sources such as that released by microbes. This led to much uncertainty in the scientific community over the reasons for this...

The Study of River Morphology

River morphology is a scientific field that concerns with changes in river forms in plan and cross-sections that result because of erosion and sedimentation processes. The principal elements are the dynamics of sediment transport and river flow. Studies on the river morphology provide important information required for the management of water resources, constructions along the river banks and in mitigating hazards such as floods, etc (Sarkar, 2016). Approaches to Studies on River Morphology in India India...

The Concept of Environmental Flow and Sustainability

Minimum ecological flow is based on the principle that a certain amount of minimum flow must be present in a flowing freshwater ecosystem such as a river or an estuary so that the ecological quality of the flowing freshwater ecosystem is maintained. The term minimum ecological flow is also used sometimes, in association with the term environmental flow that denotes the amount of water running in a flowing freshwater body that can keep the water body at a desirable environmental condition. The Concept...

Systems for the Classification of Natural Vegetation

As far as the classification of natural vegetation is concerned, it has been a constantly evolving field over the years. The classification of natural vegetation helps in forming an inventory of local vegetation and its monitoring. Classifying natural vegetation also assists in the management of programmes for natural conservation, managing land and natural resource use and in documenting individual species. Many a time, endangered habitats can be identified while classifying natural vegetation. The...

How earth’s albedo effects global warming: can geoengineering help?

Definition Albedo is the measure of reflectivity of an object. A scientific definition describes albedo as “the fraction of the total incident solar radiation reflected by a planet back to space that is a measure of the planet's energy balance”. Every object has a different albedo. The objects with higher albedo are cooler in temperature than the objects that have a lower albedo.  It is either measured on a scale of zero to one or as a percentage. An object that has zero albedo reflects zero...

Foraminifera Fossils Indicate Sea Level Change in Lothal

Foraminifera are sea organisms which have been widely used in palaeoceanography. The organisms indicate sea level changes and have played a significant role in identifying the oldest dockyard at Lothal in Gujarat.

Geopolitics of the Poles in the Anthropocene Age

We need to realise that climate change under the Anthropocene, the present era of human civilization, may have long ranging impacts on the two Polar regions and therefore make some essential policy changes accordingly.

Climate Change and the Glacial Realms

The cryosphere acts as sensitive thermometers recording the fluctuations in the climate. The Antarctic, the Arctic and the Himalaya are all showing signs of increasing ice mass loss on a decadal scale as a consequence of average rise of 0.8 oC in global temperatures since 1880 (IPCC, 2013). The meteorological observatories in the Arctic, the Antarctic and Tibet—demonstrate a rise in temperature over the last three decades.
