Order of the National Green Tribunal (Eastern Zone Bench, Kolkata) in the matter of Sridhar Samal Vs State of Odisha & Others dated 06/03/2024. The matter related to pollution caused by Talcher Coalfield under Mahanadi Coalfields Limited in the course of its operation. It was said that on a daily …
The rate of deforestation in the Brazilian Amazon has plummeted by 77% in the past seven years, but annual carbon emissions associated with deforestation have not fallen nearly as much, says a Brazilian study that combines satellite data and biomass maps to model the change. The difference is in large …
The amount of sea ice in the Arctic has fallen to the lowest level on record, a confirmation of the drastic warming in the region. Satellites tracking the extent of the sea ice found over the weekend that it covered about 1.58 million square miles, or less than 30 per …
Arctic sea ice appears to have broken the 2007 record daily extent and is now the lowest in the satellite era. With two to three more weeks left in the melt season, sea ice continues to track below 2007 daily extents.
Sea ice is frozen sea water that waxes and wanes in response to the cooling and warming of the Arctic throughout the year. The ice pack reaches its greatest extent at the end of the winter, during March, and its lowest point at the end of the summer, usually in …
Glaciers are among the best indicators of terrestrial climate variability, contribute importantly to water resources in many mountainous regions and are a major contributor to global sea level rise. In the Hindu Kush–Karakoram–Himalaya region (HKKH), a paucity of appropriate glacier data has prevented a comprehensive assessment of current regional mass …
A measurement by satellite altimetry shows the Himalayan glaciers to be losing mass at only moderate rates, but raises broader questions about other methods for estimating mass balance.
In sharp contrast to the decreasing sea ice coverage of the Arctic, in the Antarctic the sea ice cover has, on average, expanded since the late 1970s. More specifically, satellite passive-microwave data for the period November 1978–December 2010 reveal an overall positive trend in ice extents of 17 100 ± …
Glaciers of the Himalaya contribute significantly in the processes linking atmosphere, biosphere and hydrosphere, thus need to be monitored in view of the climatic variations. In this direction, many studies have been carried out during the last two decades and satellite-based multispectral data have been used extensively for this purpose …
Groundwater is a life-sustaining resource that supplies water to billions of people, plays a central part in irrigated agriculture and influences the health of many ecosystems. Most assessments of global water resources have focused on surface water but unsustainable depletion of groundwater has recently been documented on both regional and …
The surface of Greenland has turned to slush. Satellite data shows that a warm spell earlier this month melted nearly the entire surface of the nation's ice cap. The melt is unusual: normally about half of the ice sheet melts at the surface during summer, mostly at low elevations.
Carbon emissions from cities represent the single largest human contribution to climate change. Here we present a vision, strategy and roadmap for an international framework to assess directly the carbon emission trends of the world's megacities.
While unplanned colonies retain a negative image for most city planners, pragmatic reasons favour their regularisation. A large number of Delhi's residents live in such unauthorised colonies, most of which are now being regularised. But just how many people, and what changes for them through regularisation? This process does not …
Limitations in current capabilities to constrain aerosols adversely impact atmospheric simulations. Typically, aerosol burdens within models are constrained employing satellite aerosol optical properties, which are not available under cloudy conditions. Here we set the first steps to overcome the long-standing limitation that aerosols cannot be constrained using satellite remote sensing …
The Greenland GPS Network (GNET) uses the Global Positioning System (GPS) to measure the displacement of bedrock exposed near the margins of the Greenland ice sheet. The entire network is uplifting in response to past and present-day changes in ice mass. Crustal displacement is largely accounted for by an annual …
DURGAPUR, 18 JULY: The Durgapur police has asked freight services operators to intensify use of Global Positioning Satellite(GPS) technology across the Asansol – Durgapur industrial hub. This, the police believe, “would help to detect hijacked vehicles and improve freight flow and contribute to reduced congestion and pollution.” The police also …
India's 3400-kg communication satellite GSAT-10 is now ready to be shipped to the spaceport at Kourou in French Guiana for launch by European space consortium Arianespace in two months, according to Indian Space Research Organisation Chairman, K Radhakrishnan. “GSAT-10 with 30 transponders is ready to be shipped for launch. This …
The majority of glaciers on the Tibetan plateau and in the surrounding region are retreating rapidly, according to a study based on 30 years of satellite and field measurements.
New Delhi: To keep track of the development being carried out in NCR, the government has commissioned a study based on inputs from satellite imageries. The data, that will show the change in land use between 1999 and 2012, will be used for realistic planning in the region. It will …
Karad City is situated on the bank of confluence of river Krishna & Koyana, which is severely flood prone area. The floodwaters enter the city through the roads and disrupt the infrastructure in the whole city. Furthermore, due to negligence of the authorities and unplanned growth of the city, the …
