The Uncharted Waters Beneath the Ice

Antarctica, a vast expanse of ice and land, harbours one of the most intriguing features under its ice—the subglacial lakes. These isolated lakes form a part of the basal hydrological system and conceal unique biological ecosystems and climate records,thus prompting more scientific missions along with numerous challenges.

Research Studies on Stratospheric and Tropospheric Ozone

Studies show that ozone pollution is harmful for crop production while ozone depletion is damaging for aquatic ecosystems. Emission of ozone depleting CFC-11 is on the rise in Eastern Asia.

Tropospheric Ozone and Food Productivity

Ozone is life threatening if found to be increasing near the earth’s surface as it is toxic to life when inhaled. Ozone not only damages airways, but also reduces crop yields as well if it increases beyond the threshold levels. Worries are mounting as India marks a rate of increase of around 1 per cent each year. Anthropogenic sources of emissions are responsible for increase in surface ozone, which needs urgent control in the near future.

The Vanishing Aravalli

One of the oldest mountains of the subcontinent, the Aravalli play a significant role in arresting the onslaught of the deserts from western Rajasthan and beyond, apart from preserving the rich cultural heritage. Critically, the ranges also recharge the depleting aquifers of the region.

Soil Erosion and Conservation in India

Soil erosion in India Excessive soil erosion in India combined with consequent high rate of sedimentation in reservoirs and decreased soil fertility has led to grave environmental problems. Soil erosion mostly affects practically all kinds of lands such as the forest lands, agricultural lands, arid and semi-arid lands, surface mines, roads, construction sites, coastal areas etc. Further, since soil formation is a very slow process, the erosion of the upper layer of the soil leaves it barren for a long...

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...

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...

Climate Change in the Southern Ocean

Although Antarctica is better protected by international legislations, the Arctic usually commands most of the attention among climate watchers, especially in the case of the melting of sea ice and its subsequent impacts. However, like the Arctic Ocean, Climate Change in the Southern Ocean also deserves the attention of climate watchers. The Importance of the Southern Ocean Climate Change in the Southern Ocean is incredibly relevant, given that greater than 60 per cent of the Earth’s anthropogenic...

Climate Change in the Svalbard Archipelago in Norway

The Arctic region is experiencing the effects on Climate Change more than most regions on Earth and as such, Climate Change in Svalbard, which lies in the Arctic region deserves special attention. The Svalbard archipelago is located in the Arctic Ocean, about halfway between Norway and the North Pole, and is under the jurisdiction of the Norwegian Government.
