Biodiversity as Conservation | Threats & Conservation Efforts

Thomas Lovejoy in 1980 coined the term ‘Biological Diversity’ which was later modified by E. O. Wilson in 1986 who coined the term ‘Biodiversity’ in his report for the first American Forum on Biological Diversity. As a term intimately related to environmental and wildlife conservation, although the popularity of the term has increased dramatically since then in the West, especially in the scientific community in the West as well as globally, biodiversity as conservation is still not an everyday...

Very Severe Cyclonic Storm OCKHI

A trough of low at mean sea level lay over southwest Bay of Bengal & adjoining Sri Lanka coast on 27th November, it was seen as a low pressure area over southwest Bay of Bengal and adjoining areas of southern Sri Lanka & equatorial Indian Ocean on 28th, as a well marked low pressure area over southwest Bay of Bengal and adjoining equatorial Indian Ocean and Sri Lanka at 0530 hours IST of 29th November and concentrated into a depression over southwest Bay of Bengal off the Sri Lankan coast....

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.

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 major river catchments in the Indian subcontinent. This discharge of headwater makes up for about 70 to 80 per cent of the melting of snow and ice from the highlands. In such a scenario,...

The Basic Possible Impacts of Climate Change in the Himalayas

Climate Change in the Himalayas is a major topic of worry for climate watchers in the Subcontinent and across the world. The Himalayas have the largest deposits of snow and ice in the world outside the Polar Regions and is often referred to as the ‘Third Pole’ and also as the ‘Water Tower of Asia’. Climate Change in the Himalayas: The Basic Possible Impacts The issue of Climate Change in the Himalayas is drawing forward many observations, with observations of warming in the Himalayas...

Climate Change Severe Threat to Himalayan Glaciers

Many studies on wastage of Himalayan glaciers have come to the conclusion that Himalayan glaciers are retreating with varying rates of retreat between individual glaciers. This glacial retreat can vary between a few meters to up to 61 m/year. Also, mapping carried out of an area of about 11,000 sq km out of 40,000 sq km of glaciated area revealed that about 13 percent of the area has been lost in the last 4 to 5 decades (Kulkarni & Karyakarte, 2014). In this wastage of Himalayan glaciers or a negative...

Climate Change and Antarctic Biodiversity

Not being residentially inhabited by human populations and instead being a place where largely scientific research is the mainstay, one would expect Antarctic biodiversity to be more protected than biodiversity in other, more populated regions of the world. However, this may not be the case for Antarctic biodiversity. The Status of Antarctic Biodiversity A study published in 2017 in the journal PLOS Biology by a team led by Steven L. Chown and scientists from Monash University, Australia has brought...

Climate Change and Marine Mammals in the Arctic

The effects of climate change are being felt in the Arctic more immediately and severely than in most other regions in the world. Even inferentially, the Arctic is warming at a rate that is two times that of the global average. The thing that is most visible and catches the world’s attention is the lessening of Arctic sea ice along with permafrost and the changing Arctic weather, leading to a rapid decline also in glacial ice in Greenland. However, climate change also affects Arctic marine mammals,...

Himalayan Medicinal Plants and Plant Biodiversity

Indigenous knowledge has great scientific value as it can be instrumental in efforts towards scientific raw data and also conservation. Such is the case of indigenous knowledge of Himalayan medicinal plants, which can be rooted in a culture’s heritage. This can be severely affected by climate change, with most biodiversity occurring up to an altitude of 2,000 m mainly due to rainfall and sunlight. An increase in rainfall and warming due to climate change could greatly affect plant biodiversity...
