Greenhouse gas concentrations in the atmosphere hit new record highs in 2022, with no end in sight to the rising trend, according to this new report by the World Meteorological Organisation (WMO). This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface …
Everybody from governments to ngos has missed a key point about the Kyoto Conference. Everyone has focused upon the problem of global warming and how developed and developing countries should work together to reduce the emissions of carbon dioxide and other greenhouse gases. The critical issue that we are dealing …
The time taken by the Earth to rotate fluctuates by milliseconds every day. Experts say that it might be due to atmospheric changes, high and low tides, and likely movements in the Earth's core that are constantly shifting the planet's mass. To keep track of the Earth's vagaries, scientists at …
'laboratory' is an odd name for a place that receives 10,000 visitors every year; where various organisations involved, recognise its heritage responsibilities and preserve old buildings and whose historic locations feature on ever more cruise liner tourist brochures. If you have a few thousand dollars to spare, you too can …
A prototype solar device that produces enough hot air from the sun's rays to drive the turbines of a 50 kw power station has brought the prospect of cheap, solar-generated electricity a step closer. The solar energy collector has been successfully tested by Israeli researchers at the Weizmann Institute of …
It has long been hypothesised that the composition of the atmosphere has been modified by processes in the interior of the planets. Now, some researchers have done simulations for the atmosphere of Neptune and reported that some of the gases in its atmosphere are originating from deep within the planet. …
EXTRATERRESTRIAL life has been speculated about by many scientists for long. Some efforts like the search for extraterrestrial intelligence have been going on for some time now, though most of the research has been at the theoretical level. With the discovery of giant planets and other solar systems (planets orbiting …
THE fear of being choked to death by a smog of atmospheric carbon monoxide (co) has prevailed ever since the beginning of the industrial revolution (New Scientist, Vol 151, No 2045). The study of co gas is important because the levels of its emission are much more than that of …
crew members on the American space shuttle Columbia may have been at a loss when a tethered satellite broke free and drifted away. But for Robert J Charlson, an atmospheric scientist with the University of Washington, Seattle, the aborted mission was a blessing in disguise. The astronauts now had the …
human assault on the earth's atmosphere continues. Recently, the World Meteorological Organization ( wmo ), a un agency based in Geneva, revealed that the ozone hole measured over the Antarctic during the South Hemisphere spring, is already twice the size of Europe. The hole, first observed in the Antarctic in …
Annual emissions of anthropogenic Hg to the atmosphere in different regions of the world during the last decade show an interesting dichotomy: the emissions in the developed countries increased at the rate of about 4.5–5.5% yr−1 up to 1989 and have since remained nearly constant, while in developing countries the …
AN ESTIMATED 35 million tonnes of methane goes up into the atmosphere each year, thanks to leaks in Russian gas pipelines and wellheads, says an unpublished report from Russian researchers. This comes to around a tenth of all anthropogenic emissions of the gas, second only to carbon dioxide as a …
The Infrared Space Observatory (ISO) has detected Water inthe planetary nebula NGC7027. The ISO is ideally suited for observations, since it is outside the earth's atmosphere, which acts a major absorber of infrared radiations. Thus a major advance has been made in solving the "missing oxygen problem". The amount of …
ALL the diatribe and deliberations about protecting the ozone layer have not been just a lot of talk. Recently scientists reported that the concentration of ozone-depleting chemicals in the lower atmosphere began decreasing for the first time last year since their introduction in the early '60s. The discovery has revived …
IT IS the phosphorus element that holds the key to the oxygen feedback mechanism, according to Philippe Van Cappellen of the Georgia Institute of Technology in Atlanta and Eltery Ingall of the University of Texas at Austin, us. Atmospheric oxygen is mostly produced by the photosynthetic algae floating on the …
WHILE the debate on global warming -continues, the detection of an astounding 45 per cent depletion of the mone layer, over an area stretching froth Greenland to western Siberia, gives atmospheric scientists MoTe woorries. The discovery was repwted by the World Meteorological Organization, a United Nations agetcy, in Geilmeva, Switzerland, …
Opinions on Jupiter's evolution have undergone a revision, following the data sent by the Galileo probe. Previous measurements had suggested that Jupiter contained about 10 times more oxygen than the sun. The old theory says that young Jupiter, bombarded by comets containing carbon, nitrogen and oxygen, became much richer in …
THE race to save the depleting ozone layer may yet be won. Scientists belonging to the Yale University in New Haven, us, announced recently that they have discovered a new method by which chlorofluorocarbons (CFCs) which eat into the ozone layer can be broken down into harmless derivatives. A particular …
THE NOBLE for chemistry for the Year 1995 to three atmospher- Scientist on October 11, is a vindication for environmentalists who have Wl6m boarse for decades over phown caused by humanmade LUC WMDcrs of the us $1 million we Dutch scientist Paul k1ft Un Planck Institute for Oft bdamz Germany, …
With anti nuclear sentiments riding High today, porticularly in developing Countries it is appropriate that the hd Peace Prize went to an active besnifter inespon campaigner - ob 1, 11 and his Pugwash Siftfillon. 'I really feel that it is Id tor dw scientific community," liftid" In response to the …
RECENT research findings have come as a breath of fresh air. A study based on data from 27 monitoring stations all over the world reveals that the carbon monoxide levels in the atmosphere have taken a nosedive and the atmosphere is getting cleaner for the first time in 3 decades …
