Order of the National Green Tribunal in the matter of In Re: News Item titled "Nayar river is vanishing - a yatra reveals conservation goes beyond science and policy" appearing in ‘The Down To Earth’ dated 03.06.2025. The original application was registered suo-motu based on the news item titled "Nayar …
Temperature reconstructions for the surface of the Northern Hemisphere are based largely on terrestrial records from extra-tropical or high-elevation sites, despite the fact that global average surface temperature changes closely follow those of the global tropics, which are 75 per cent ocean. Here, a decadally resolved continuous sea surface temperature …
The Western obsession with curbing carbon emissions is wicked and also economically foolish Deepak Lal / New Delhi August 25, 2009, 0:35 IST The Western obsession with curbing carbon emissions is wicked and also economically foolish, says Deepak Lal Three cheers for Jairam Ramesh! India at last has an environment …
Estimation of soil organic carbon (SOC) is indispensable in studies involving soils and global climate change. SOC retention in soil is a function of climate, vegetation and intrinsic soil properties. Historically, SOC estimates are based on wet digestion which gives low carbon recovery. This results in underestimation of its density …
Aug. 23: The city-based National Geophysical Research Institute has set up a geothermal climate change observatory at Choutuppal near here. The observatory can find and record warming and cooling of the earth in the last 300 years, apart from giving data on the meteorological conditions. The observatory
A geothermal climate change observatory, set up by scientists of the Geothermal Studies Group of the National Geophysical Research Institute (NGRI), was inaugurated at Choutuppal, near here. The observatory, which comprises an automatic weather station located next to a set of boreholes going down 210 metres, will allow scientists to …
Reliable forecasts of climate change in the immediate future are difficult, especially on regional scales, where natural climate variations may amplify or mitigate anthropogenic warming in ways that numerical models capture poorly. By decomposing recent observed surface temperatures into components associated with ENSO, volcanic and solar activity, and anthropogenic influences, …
The correspondence by Upadhyay is yet another addition to the hype that the Himalayan glaciers are melting and cause serious damage to the Himalayan eco-system. The entire interpretation is based on evidences that have been collected from places that are several kilometres away from the present-day snout of the glacier.
Atlantic tropical cyclone activity, as measured by annual storm counts, reached anomalous levels over the past decade. The short nature of the historical record and potential issues with its reliability in earlier decades, however, has prompted an ongoing debate regarding the reality and significance of the recent rise. Here the …
Researchers in the United States and Europe are seeking funding so that the ice cores used to study Earth's past climate can have the same luxuriously chilly storage facilities currently enjoyed by prize tuna. The cylindrical cores, drilled at multi-million-dollar expense from polar and glacial ice, can be kilometres long. …
The Arctic tundra is one of the world's most extensive ecosystems, and the frozen soil known as permafrost, which underlies it, can be hundreds of metres deep. But as the world warms up in response to the millions of tonnes of carbon dioxide and other greenhouse gases being poured into …
The low 13C/12C ratio in some Neoproterozoic carbonates is considered to be evidence of carbon cycle perturbations unique to the Precambrian. Here, all published oxygen and carbon isotope data for Neoproterozoic marine carbonates are compiled. The combined isotope systematics are found to be identical to those of well-understood Phanerozoic examples, …
health Side-effects stay Chemicals called contrast agents used during cardiac angiography can seriously damage kidneys which, in turn, increases chances of heart attacks. Side-effects were earlier thought to be temporary. A team tracked 294 patients exposed to contrast agents for a year. 31 per cent of the patients were found …
The feedback between the terrestrial carbon cycle and climate is one of the largest uncertainties in current projections of future climate, with the long-term sensitivity of carbon in peatlands remaining unclear. The combination of non-disturbing in situ measurements of carbon dioxide respiration rates and isotopic composition of respired CO2 in …
Across the United States, researchers are firing up experiments to determine how rising temperatures could reshape the nation's forests. The studies encompass the pines and maples of eastern forests in Massachusetts and North Carolina, the spruce and fir of northern Minnesota, and the alpine tundra ecosystem above the treeline in …
The low-grade meta-sedimentary sequence of the Sirohi Group comprises an ensemble of phyllite, schist and meta-carbonate rocks (including impure marble) and marks late Proterozoic tectonics in the NW Indian block. The ? 18OV-PDB values for Sirohi meta-carbonates range from
Feedbacks involving low-level clouds remain a primary cause of uncertainty in global climate model projections. This issue was addressed by examining changes in low-level clouds over the Northeast Pacific in observations and climate models. Decadal fluctuations were identified in multiple, independent cloud data sets, and changes in cloud cover appeared …
Ice cores extracted from the Antarctic ice sheet suggest that glacial conditions and the relationship between temperatures and atmospheric carbon dioxide concentrations have been constant over the last 800,000 years, but there is some evidence for a fluctuating severity of glacial periods mediated by previously unidentified mechanisms. Variable migration of …
