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 …
Deposits in a Chinese cave tell the story of the region 's climate stretching back more than 200,000 years, well past the last interglacial warm period
We should not wait to cut back on burning fossil fuels until we have developed greener technology to supply our energy needs, despite what many economists are advising their respective governments. Such a waiting game may have deadly consequences. Feb 27, 2008
One of the biggest challenges in climate research is to arrive at reliable future projections. However, while there now exists a firm scientific basis and procedure for climate forecasts, numerical climate models still suffer from large uncertainties.
One million tons of atmospheric carbon dioxide are dissolved into the oceans every hour, a process that helps maintain the Earth's delicate carbon balance. But CO2 also makes seawater more acidic, and too much of it can wreak havoc on a marine species.
Terming the hype and panic over "global warming' as "unnecessary', well-known hydro-geologist Ritesh Arya seeks to redefine the phenomenon as a natural cyclic process for transporting the weathered and eroded material accumulated during the global cooling phase in the past. Arya, who shot into limelight for harnessing ground water in …
Judging the effect of climate change on ocean currents could take longer than we thought. The circulation of warm water in the North Atlantic is suspected to be slowing, and the worry is that global warming is to blame.
A high-throughput protocol was developed for the synthesis of zeolitic imidazolate frameworks (ZIFs). Twenty-five different ZIF crystals were synthesized from only 9600 microreactions of either zinc(II)/cobalt(II) and imidazolate/imidazoloate-type linkers.
Clouds have always given climate modelers fits. The clouds in their models are crude at best, and in the real world, researchers struggle to understand how clouds are responding to-and perhaps magnifying-greenhouse warming; But two new studies now show that much of the worry about clouds' role in the warming …
Trees are not very effective as carbon sinks trees may not be the insurance against global warming we all thought they were. Their ability to store carbon dioxide has diminished due to rise in temperatures and hence they will not be able to act as carbon sinks. Scientists studied two …
The Turonian (93.5 to 89.3 million years ago) was one of the warmest periods of the Phanerozoic eon. It has been argued that there may have been several stages of continental ice growth during the period, reflected in both erosional surfaces and geochemical records associated with possible glaciation-induced sea-level falls.
The consequences of global climate change are profound, and the scientific community has an obligation to assess the ramifications of policy options for reducing greenhouse gas emissions and enhancing CO2 sinks in reservoirs other than the atmosphere. Ocean iron fertilization (OIF), one of several ocean methods proposed for mitigating rising …
In a research by paleoceanographer Andre Bornemann of Leipzig University in Germany and his colleagues analyzed apparently unaltered Foraminifera picked from sediment core drilled from Demerara Rise beneath the western equatorial Atlantic. Following a classic technique, the researchers measured oxygen isotopes in the forams' shells. They found a sharp shift …
Last year, climate change scientists thought they had driven a silver stake through the idea that fluctuations in solar activity were behind global warming in the last century. Now, a high-profile team led by geophysicist Vincent Courtillot, director of the Institut de Physique du Globe in Paris, has sought to …
there has been a 35 per cent increase in carbon dioxide emissions worldwide since 1990. Inefficient fossil fuels have contributed to a 17 per cent increase in carbon dioxide emissions and an 18 per cent loss in the absorption capacity of sinks, oceans for example. Scientists associated with the Global …
Companies and countries are planning a series of controversial experiments to help determine if seeding the ocean with iron can mitigate global warming.
