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. Fig: Norway in Northern Europe including the Svalbard Archipelago Source: Maps Of World, 2017 Climatic Conditions in Svalbard The...

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 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,...

Warming Trend | Antarctic Climate Change in the Last Fifty Years

Antarctic climate change is older than most would assume, and Antarctica did not always have the climatic features that it possesses now. Antarctica had been much warmer in its distant geological past, such that there are fossils to indicate that trees grew in Antarctica at various geological times. As expected, Antarctica was placed in different locations many millions of years ago and with the movement of tectonic plates, this played a significant part in influencing Antarctica’s climate in the distant...

CLIMATE CHANGE | The KoppenTrewartha Climate Classification System

Basics of the Koppen Trewartha Climate Classification System Wladimir Koppen developed the first quantitative classification system for the Earth’s climate in his first model in 1900 (Kottek et al., 2006). Since Koppen, many different climate classification models have been developed, but the Koppen climate classification system (Koppen, 1923, 1931, 1936) with various modifications to its original form remains the dominant climate classification model. In contemporary times, the most highly...

Black Carbon as an Important Climate Change Challenge

Black carbon is a substance responsible for up to 40 per cent of the effects of global warming till date (Philadelphia Tribune, 2017), most of it made up of soot. Black carbon is a form of particulate matter that can be airborne and can be suspended in the atmosphere and travel thus. When this particulate matter gets deposited on frozen surfaces such as in the Arctic or in Himalayan glaciers and snow, its high absorption of the Sun’s heat causes the frozen material to melt and liquefy. The US Environmental...

The Environment and Atomic Policy of the UN

Changes in Global Atomic Policy The 2005 Nobel Peace Prize was awarded jointly to the International Atomic Energy Agency (IAEA) and Mohamed El Baradei in lieu of their work in preventing military use of nuclear energy and for their efforts towards the safest possible standards of the use of nuclear for peaceful purposes. The United Nations (UN) is aware that the UN came to fore at the dawn of the nuclear age late into the 1940s. The environment and atomic policy of the UN as such was greatly...

The Koppen Climate Classification System

The Koppen climate classification system is a widely-utilized vegetation-based climate classification system that was created by the German botanist and climatologist Wladimir Koppen. The Koppen climate classification system is an attempt to come up with a formula to delineate climatic boundaries in correspondence with vegetation zones or biomes across the globe. These biomes were in the process of being formulated and mapped for the first time during the time Koppen formulated his climate classification...
