The matter related to improper disposal of fly ash by the thermal power station run by National Thermal Power Corporation (NTPC), Kanti, Muzaffarpur, …
POISONING of nature is a constant obsession with BBC's Nature series. The latest episode in the series was on the ubiquitous yet controversial chlorine, a chemical the programme dubs as "The Devil's Element". The title has been derived from the words of a professor of environmental chemistry: "There are 91 …
SCIENTISTS have confirmed environmentalists' fears about the depletion of the ozone layer, by measuring a 50 per cent increase in the ultraviolet radiation striking Ushuaia in south Argentina. According to a report recently published in the Journal of Geophysical Research, the increase occurred in December 1990 when a piece of …
Human-induced changes in the composition of the atmosphere has lent urgency to the task of understanding their effect on the earth's climate, which is crucial to life on the planet. Atmospheric concentration of carbon dioxide, a greenhouse gas found in abundance on earth, has increased by more than 25 per …
PALAEOCLIMATIC data -- geological evidence of climatic change contained in fossils, rocks, sediments and ice -- play a crucial role in studies of atmospheric changes and their effect on climate because it is the only empirical evidence of what happened in the past. Such data serve as a yardstick to …
COMPARISONS between planets in the Solar System, which have distinct atmospheres, especially Mercury, Venus, Earth and Mars, cast light on the massive interactions that determine the evolution of climates. Mercury, the planet closest to the Sun, has an extremely tenuous atmosphere, consisting mainly of hydrogen, helium and nitrogen, which are …
Everyone these days is aware of the phenomenon of global warming, even if they find it difficult to distinguish between stratospheric ozone depletion and the greenhouse effect. Global Warming: The Economic Stakes is about the greenhouse effect and the resultant environmental pollution and global damage. Incoming radiation from the sun …
TRADITIONALLY associated with young lovers and new life, spring may soon become a time of worry because new data shows winter depletion of the protective ozone layer over Antarctica begins much earlier than was believed. The data also shows ozone levels over the Northern Hemisphere are falling rapidly. Both findings …
A VOLCANIC explosion does not affect only those living in the vicinity -- it's impact can be global and it may be felt for years afterwards. A volcanic eruption can cause unexpected changes in the earth's climate and environment and the onset of the Ice Age, global cooling, depletion of …
EVEN THOUGH tough environmen- Indian delegation that took part in tal negotiations are still ahead in the the earlier discussions have been post-Rio Summit phase, many on the replaced. This could easily put India. at a disadvantage in forthcoming Ozone, Biodiversity and Climate Change convention and at meetings of the …
JAPANESE scientists hail environmental technology as the new frontier of science. Surveyed on breakthroughs they consider likely in the next generation, scientists listed 1,149 topics in 16 fields. The survey was conducted by the Japanese Science and Technology Agency. Among their predictions: the first major discovery will probably be a …
TWO RECENT climate studies have found that while changes in solar radiation do contribute to global warming, this effect is small as compared to that of human-made greenhouse gases. The increase in the annual average global temperature at the earth's surface was as much as 0.8o C between 1880 and …
YOU CAN now bank on the environment -- at least at the nine Punjab National Bank (PNB) branches that will underwrite projects friendly to both customers and the environment. In a trend-setting move, PNB branches will encourage ecologically safe projects such as organic farms, fruit and vegetable cooperatives for the …
HAS THE "eco-angel" fallen from grace? Fourteen years after West Germany adopted eco-labelling, its efficacy is still in doubt because of faulty selection and inadequate evaluation of product impact. Today, the eco-angel -- the blue angel symbol that denotes environment-friendliness of a product -- adorns as many as 3,600 products, …
IN THE US, private eco-label schemes, whose environmental monitoring and approval is based on an analysis of the product through its life-cycle, have taken front-seat, because the state-owned US Environmental Protection Agency has remained wary of endorsing a product as ecologically superior. Two such groups are Green Seal and Green …
RECENT findings that global warming of the lower atmosphere could trigger major ozone destruction have added an alarming new dimension to the climate change scenario (Nature, Vol 360 No 6401). British scientists John Austin of the Meteorological Office, Neal Butchart of the Hadley Centre for Climate Prediction and Keith Shine …
BETWEEN 1986 and 1990, the total consumption of ozone-depleting chlorofluorocarbons (CFCs) by industrialised countries dropped from 971,342 tonnes to 636,588 tonnes -- a fall of 34 per cent. The industrialised countries' halon consumption, too, has fallen from 198,609 tonnes to 151,700 tonnes. Meanwhile, the CFC consumption of developing countries, which …
After being spewed into the atmosphere for the past 30 years, mainly through the use of fire extinguishers, ozone-depleting halon concentrations are now decreasing (Nature, Vol 359 No 6394). Although halons H-1301 and H-1211 are each present in the troposphere at a concentration of two parts per trillion, the gases …
DURING the 1992 September-October southern spring, the world's ozone layer dropped to the lowest levels recorded in 35 years. According to the World Meteorological Organisation (WMO), the ozone levels over northern Europe, Russia and Canada last winter and spring were 12 per cent below the seasonal average. The Antarctic ozone …
DISAPPOINTMENT among green NGOs and irritation among developing countries over the foot-dragging attitude of some developed countries characterised the week-long meeting in Copenhagen of the parties to the so-called Montreal Protocol. But alarming data presented on the state of the ozone layer, which protects life on earth from the sun's …
THE FOURTH Conference of Parties (CoP) to the Montreal Protocol, scheduled for later this month in Copenhagen, promises to be a hot affair. The government of India has prepared a detailed report on its strategy to phase out ozone-depleting substances, in which it has criticised the inequitable nature of the …
