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 …
This report aims to improve understanding about the linkages between trade and climate change. It shows that trade intersects with climate change in a multitude of ways. The report begins with a summary of the current state of scientific knowledge on climate change and on the options available for responding …
Current global warming affects the composition and dynamics of mammalian communities and can increase extinction risk; however, long-term effects of warming on mammals are less understood. Dietary reconstructions inferred from stable isotopes of fossil herbivorous mammalian tooth enamel document environmental and climatic changes in ancient ecosystems, including C3/C4 transitions and …
Permafrost thaw and microbial decomposition is considered one of the most likely positive climate feedbacks from terrestrial ecosystems to the atmosphere in a warmer world, but the rate of carbon release from permafrost soil remains highly uncertain. Here, net ecosystem carbon exchange is measured in a tundra landscape undergoing permafrost …
Underwater archaeology is revealing how ancient civilisations coped with rising seas, and while their methods were basic, they still have relevance today.
Mars may have once been both cold and wet, researchers said Wednesday, suggesting a freezing Martian landscape could still have produced water needed to sustain life. There has been debate over the issue because with some researchers believing water likely formed many features of the planet's landscape and others pointing …
Ice crystals plucked from clouds and quickly analysed in flight show bits of biological material -- bacteria, spores and plants -- play a role in the formation of clouds, US researchers said on Sunday. The finding, reported in the journal Nature Geoscience, offers the first direct evidence of airborne bacteria …
Climate warming has advanced the biological spring and delayed the arrival of biological winter. These changes in the annual cycle of plants and the lengthening of the green-cover season have many consequences for ecological processes, agriculture, forestry, human health, and the global economy. Studies on vegetation-atmosphere interactions and particularly on …
Theory has suggested that the West Antarctic Ice Sheet may be inherently unstable. Recent observations lend weight to this hypothesis. This article reassess the potential contribution to eustatic and regional sea level from a rapid collapse of the ice sheet and find that previous assessments have substantially overestimated its likely …
Volume changes in the Antarctic Ice Sheet are poorly understood, despite the importance of the ice sheet to sea-level and climate variability. Over both millennial and shorter time scales, net water influx to the ice sheet (mainly snow accumulation) nearly balances water loss through ice calving and basal ice shelf …
Global warming began in the 18th century glaciers, both in the northern and southern hemispheres, started melting in the mid-eighteenth century, triggered by climate change. Researchers from the Wadia Institute of Himalayan Geology in Dehradun tracked the age of lichens (a composite organisms formed by the association of fungi and …
Carbon emissions harm marine organisms studies linking an increase in the levels of atmospheric carbon dioxide to the acidification of oceans are widely reported and accepted. The effects of acidification on marine life are not well understood. A team showed a direct link between ocean acidification and decrease in the …
Mathematical modelling and time series analysis techniques are important tools for extracting information from complex geotime series. These techniques also facilitate a fair degree of prediction, which is one of the prime goals of science. The data analysis strategy for such a purpose mainly involves spectral analysis and pattern classification. …
Surface meltwater that reaches the base of an ice sheet creates a mechanism for the rapid response of ice flow to climate change. The process whereby such a pathway is created through thick, cold ice has not, however, been previously observed. We describe the rapid (<2 hours) drainage …
New Delhi: Good news first. If the world restricts its carbon emissions to 190 giga tonnes by 2050, there is 75% chance that it will escape the catastrophic consequences of global warming. The bad news: last year alone, the world emitted more than 9 giga tonnes of carbon by burning …
BALASORE: Launch of an ocean satellite is the next mission of Indian Space Research Organisation (ISRO) after the successful launch of Chandrayaan-1, said G Madhavan Nair, ISRO chairman and Secretary of the Department of Space. Nair who was here recently to attend the fifth convocation of Fakir Mohan University told …
The United States intends to work toward reducing emissions of potent greenhouse gases found in refrigerators and air conditioning systems but has not yet decided which international venue to use to advance the issue, US officials said on Monday. In a letter to a UN agency, the US State Department …
The head of Edinburgh University Business Schoo l is intrigued by a fundamental question: why do business school academics not spin out more businesses? Nick Oliver raises the issue as Edinburgh reveals it has secured significant investment from Haymarket Media Group to support its ambition to become a leading centre …
To avoid "dangerous" climate change, we must not burn more than one-quarter of our remaining reserves of fossil fuels. That's the conclusion of the most comprehensive effort yet to work out how much carbon can be pumped into the atmosphere without pushing warming past 2
