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 …
Data laboriously extracted from an Antarctic ice core provide an unprecedented view of temperature, and levels of atmospheric carbon dioxide and methane, over the past 800,000 years of Earth's history.
Climatologists have called for massive investment in computer and research resources to help revolutionize modelling capabilities. The eventual aim is to provide probabilistic climate predictions that are as useful, and usable, as weather forecasts. At the end of a four-day summit held last week at the European Centre for Medium-Range …
Carbon dioxide (CO2) emanates from the smokestacks of coal-fired power plants and other generators and is a greenhouse gas. Existing CO2 capture techniques involve the use of solid materials that lack sufficient stability for repeated use
Few scientific creations have had greater impact on public opinion and policy than computer models of Earth's climate. These models, which unanimously show a rising tide of red as temperatures climb worldwide, have been key over the past decade in forging the scientific and political consensus that global warming is …
Significant changes in physical and biological systems are occurring on all continents and in most oceans, with a concentration of available data in Europe and North America. Most of these changes are in the direction expected with warming temperature. Here the authors show that these changes in natural systems since …
Even before the caves in Meghalaya can reveal clues to climate change, rampant mining is destroying their wealth. AMARJYOTI BORAH goes deep into the issue Meghalaya carries a bewitching world in its belly. The natural caves found in Jaintia Hills are a storehouse of geological treasures. Rivers and streams flow …
Regulating mining in Meghalaya is tricky. Since Meghalaya is a Sixth Schedule state, the state government and the mining department do not have a direct control over its mineral resources; it is the tribal people who own the land. Meghalaya is the only state in India where coal mining is …
It has been widely hypothesized that a warmer climate in Greenland would increase the volume of lubricating surface meltwater reaching the ice-bedrock interface, accelerating ice flow and increasing mass loss. We have assembled a data set that provides a synoptic-scale view, spanning ice-sheet to outlet-glacier flow, with which to evaluate …
Desiccation of the Sahara since the middle Holocene has eradicated all but a few natural archives recording its transition from a "green Sahara" to the present hyperarid desert. Our continuous 6000-year paleoenvironmental reconstruction from northern Chad shows progressive drying of the regional terrestrial ecosystem in response to weakening insolation forcing …
Soot produced by burning coal, diesel, wood and dung causes significantly more damage to the environment than previously thought, according to research published recently. So-called
"Politicians seem to think that the science is a done deal," says Tim Palmer. "I don't want to undermine the IPCC, but the forecasts, especially for regional climate change, are immensely uncertain." Palmer is a leading climate modeller at the European Centre for Medium-Range Weather Forecasts in Reading, UK, and …
Let's be clear. The science of climate change and of humanity's role in recent warming is very robust. So concerns about the ability of climate models to predict effects at the local level in no way undermine the case for urgent action to stop climate change happening. (Editorial)
In a recent paper in the journal Carbon Balance and Management (vol 3, p 1), Ning Zeng, an atmospheric scientist at the University of Maryland in College Park calculated that if we buried half of the wood that grows each year, in such a way that it didn't decay, enough …
Boreal forests serve as important global sources or sinks of carbon (C) and wildfire is a major driver of C storage in these forests. Although fire releases CO2 to the atmosphere, it also converts plant biomass into forms of black carbon, such as charcoal, that are resistant to microbial attack …
A new paper shows that regional and even global temperatures are being temporarily held down by a natural jostling of the climate system, driven in large part by vacillating ocean currents.
The effects of global warming over the coming decades will be modified by shorter-term climate variability. Finding ways to incorporate these variations will give us a better grip on what kind of climate change to expect.
Studies suggest that tropical cyclones are becoming more powerful with the most dramatic increase in the North Atlantic. The increase is correlated with an increase in ocean temperature. A debate concerns the nature of these increases with some studies attributing them to natural climate fluctuations, and others suggesting climate change …
A unique drilling project in the western Ross Sea has revealed that Antarctica had a much more eventful climate history than previously assumed. A new sediment core hints that the western part of the now-frozen continent went through prolonged ice-free phases
