Order of the National Green Tribunal in the matter of Ramdevbhai Samatbhai Sanjva Vs State of Gujarat & Others dated 09/05/2025. The matter related to remedial actions to be taken for abatement of pollution of river Bhadar near Ahmedabad. Gujarat Pollution Control Board (GPCB) has filed the response affidavit, March …
IMAGINE a hill station without pines. Worse, Canada sans the maple tree. This could be a reality. Scientists at the Hebrew University of Jerusalem in Israel claim many tree species that depend on the wind to disperse their seeds like pines and maple might become extinct due to climate change. …
The global push towards a more biomass-based energy sector is ramping up efforts to adopt regionally appropriate high-yielding crops. As potential bioenergy crops are being moved around the world an assessment of the climatic suitability would be a prudent first step in identifying suitable areas of productivity and risk. Additionally, …
A long climate record reveals abrupt hydrological variations during past interglacials in southwestern North America. These data set a natural benchmark for detecting human effects on regional climates.
A survey of bumblebees in North America provides unequivocal evidence that four previously common and abundant species have undergone recent and widespread population collapse. Various explanations remain possible.
A hallmark of the latter half of the 20th century is the widespread, rapid intensification of a variety of anthropogenically-driven environmental changes
Non-timber forest products (NTFPs) generate sizeable magnitudes of income and employment in different parts of the world for the tribal and poor people. The evidence is based on the review of past studies across different continents. The study presents a collective evidence for the role of NTFPs in development in …
THE world’s rivers are threatened due to mismanagement and pollution. This imperils eight of every 10 people as well as 10,000-20,000 species that call them home. This is the finding of the first global initiative that assessed water security for people and river biodiversity. Eleven scientists identified 23 stressors, such …
Studies diverge substantially on the actual magnitude of the North American carbon budget. This is due to the lack of appropriate data and also stems from the difficulty to properly model all the details of the flux distribution and transport inside the region of interest. To sidestep these difficulties, we …
To persist, species are expected to shift their geographical ranges polewards or to higher elevations as the Earth’s climate warms. However, although many species’ ranges have shifted in historical times, many others have not, or have shifted only at the high-latitude or high-elevation limits, leading to range expansions rather than …
In 2010 Colony Collapse Disorder (CCD), again devastated honey bee colonies in the USA, indicating that the problem is neither diminishing nor has it been resolved. Many CCD investigations, using sensitive genome-based methods, have found small RNA bee viruses and the microsporidia, Nosema apis and N. ceranae in healthy and …
The main consumer-targeted certification scheme for sustainable fisheries is failing to protect the environment and needs radical reform, say Jennifer Jacquet, Daniel Pauly and colleagues.
As part of the Global Atmospheric Passive Sampling (GAPS) study, XAD-resin based passive samplers are being deployed for consecutive one-year periods at numerous sites on all seven continents to determine annually averaged concentrations of persistent organic pollutants. Concentrations of banned organochlorine pesticides as well as a number of current-use pesticides …
Species distribution models (SDMs) are increasingly used for extrapolation, or predicting suitable regions for species under new geographic or temporal scenarios. However, SDM predictions may be prone to errors if species are not at equilibrium with climatic conditions in the current range and if training samples are not representative. Here …
As the timing of spring productivity blooms in near-shore areas advances due to warming trends in global climate, the selection pressures on out-migrating salmon smolts are shifting. Species and stocks that leave natal streams earlier may be favoured over later-migrating fish. The low post-release survival of hatchery fish during recent …
There is uncertainty about the response of the climate system to future trajectories of radiative forcing. To quantify this uncertainty we conducted face-to-face interviews with 14 leading climate scientists, using formal methods of expert elicitation. We structured the interviews around three scenarios of radiative forcing stabilizing at different levels. All …
Volcanic eruptions release a large amount of sulphur dioxide. This is oxidized to sulphate and can then form sulphate aerosol, which can affect the Earth's radiation balance. Here, past volcanic eruptions and atmospheric conditions are investigated by using sulphur and triple oxygen isotope measurements of atmospheric sulphate preserved in the …
Many large mammals became extinct worldwide at the end of the Pleistocene epoch, around 12,000 years ago. Here, it is shown that smaller mammals, which often provide much more comprehensive fossil records than large mammals, were much less likely to respond to the Pleistocene
Obese diabetics will soon have a better option to reduce their weight and consequently their blood sugar levels, with a new drug, Victoza (liraglutide), all set to be launched in India this month. Already launched in Europe and the US, the drug will hit the stores in India
Heavy rain caused by tropical storm Agatha has killed almost 100 people in Central America, where tens of thousands of people had to be evacuated over the weekend because of flooding. In Guatemala, which has been worst affected by the rains, 82 people had died, President Alvaro Colom was quoted …
