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 …
Global food security in a changing climate depends on both the nutritive value of staple crops as well as their yields. Here, we examined the direct effect of atmospheric carbon dioxide on the toxicity of the important pasture crop, Trifolium repens L. (clover). Shoots of T. repens contain cyanogenic glycosides …
Variations in climate history pinpoint biodiversity hotpots ecologists are yet to discover all the biodiversity-rich areas on this earth. One way is to map out each region after physical observation. But mapping inaccessible mountainous terrains like the Himalayas is a challenge. A scientific team claimed studying the climatic history of …
The Pliocene warm interval has been difficult to explain. We reconstructed the latitudinal distribution of sea surface temperature around 4 million years ago, during the early Pliocene. Our reconstruction shows that the meridional temperature gradient between the equator and subtropics was greatly reduced, implying a vast poleward expansion of the …
After paring 23 climate models down to the best half-dozen, two researchers now say with new confidence that arctic summer ice will most likely disappear around 2037. But none of the select models predicts a tipping point--a sudden jump to an ice-free summer Arctic.
One point repeatedly made at last week's climate change congress in Copenhagen was that formulating an action plan to curb climate change is not the job of scientists. (Editorial)
The West Antarctic ice sheet (WAIS), with ice volume equivalent to approx5 m of sea level, has long been considered capable of past and future catastrophic collapse. Today, the ice sheet is fringed by vulnerable floating ice shelves that buttress the fast flow of inland ice streams. Grounding lines are …
Thirty years after oxygen isotope records from microfossils deposited in ocean sediments confirmed the hypothesis that variations in the Earth's orbital geometry control the ice ages, fundamental questions remain over the response of the Antarctic ice sheets to orbital cycles. Furthermore, an understanding of the behaviour of the marine-based West …
During the past five million years, the West Antarctic ice sheet has waxed and waned in size. A two-pronged reconstruction of that history provides clues to the ice sheet's future behaviour.
Fish can do it by producing and excreting carbonates THE marine carbon cycle is undergoing rapid changes. An excess of unregulated carbon will eventually acidify the oceans. A new study demonstrates that fish have the potential to save the marine carbon cycle. Until now scientists believed that the calcium carbonate …
Scientists propose burying it below oceans WORLD carbon dioxide levels are rising. The future is expected to be exceptionally warm. Many technologies are being proposed to tackle it. Efficiently reducing global warming requires carbon capture in large amounts. Furthermore, the captured carbon has to stay that way for thousands of …
A model analysis of the uptake of carbon dioxide in the North Atlantic carries with it a cautionary reminder about interpreting what may be short-term trends as signals of long-term climate change.
Environment: Removing carbon dioxide directly from the atmosphere could help combat climate change. Will it really work? Preventing catastrophic climate change, most people agree, will mean reducing the level of man-made carbon dioxide (CO2) in the atmosphere. That, in turn, will require the widespread use of
Each year, on 23 March, the World Meteorological Organization, its 188 members and the worldwide meteorological community celebrate World Meteorological Day around a chosen theme. This day commemorates the entry into force, on that date in 1950, of the WMO Convention creating the Organization. Subsequently, in 1951, WMO was designated …
As the world warms up, some species cannot move to cooler climes in time to survive. Camille Parmesan thinks humans should help even if it means creating invasive species.
The distinguished climate scientist James E Hansen from NASA along with an interdisciplinary group of nine renowned scientists have put in a recent research paper titled 'Target Atmospheric CO : Where Should 2 Humanity Aim?'.They have issued a re-assessment of earlier climate change predictions.
