The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
"A REVITALISED UNEP is essential to assist the international community in its efforts to reverse environmentally unsustainable trends," stated a declaration made by the governing council of the United Nations Environment Programme (UNEP) at its 19th session in Nairobi from January 27 to February 7. The council, comprising ministers and …
lightning could be primarily responsible for global warming, as it produces a quarter of the planet's concentration of nitrogen oxides (nox), according to a recent study conducted by Colin Price and his team at the Lawrence Livermore National Laboratory in California, us (New Scientist, Vol 153, No 2066). The high …
climatologists have always regarded carbon dioxide (co2) as dangerous since it is supposed to be one of the principle causes of global warming. But then co2 also performs the valuable function of enhancing floral growth. Rise in atmospheric co2 concentration and possible concomitant climate change has been seen to affect …
"Nitrogen enrichment is pushing us towards a weedier world,' says David Wedin of the University of Toronto, Canada. Burning fossil fuel releases nitrogen oxides, which ecologists believe could act as fertilisers and promote luxuriant growth of weeds. This shift in vegetation could hinder the earth's ability to moderate global warming, …
the us has evolved a multi-pronged stra-tegy to tackle the problem of greenhouse gas emissions calling for the setting up of emission targets, reporting them and budgeting emissions by deve-loping and developed countries. According to the us state department, the guidelines will help both the developed and developing countries in …
the phenomenon of global warming is surely not confirmed as yet. An area may have become warmer not because of an increase in global warming but because of certain natural variations. But whatever be the cause, it is time we took note. For Earth as a whole, 1996 ranked among …
Bhutan could help absorb carbon dioxide (CO2) and curb global warming as greenhouse gas emissions by the country is reportedly insignificant. Results of a study on climate change conducted by two Danish consultants showed that in a completely forested area the per capita CO2 emission was 19.6 tonne, in a …
environmental commitments made by most nations at the Earth Summit in Rio de Janeiro, Brazil, five years ago, have remained on paper even as carbon dioxide emissions soared and forests and animal species continued to vanish. These are the findings of a report prepared by the Earth Council, a Washington-based …
On the beginning of the world's first green party: It all began in 1970. The Tasmanian government had decided to build a major power station which would have drowned the magnificent Lake Peddar. The campaign against the government's decision was started by a group of Tasmanian environmentalists who contested the …
jorge Sarmiento and Corinne Le Quere of Princeton University in New Jersey, us, have observed that warmer oceans are more stratified and cause the ocean circulation system to slow down. As a result, they absorb much less carbon dioxide (co2)
heating of the planet can cause the dreaded dengue fever to rise to epidemic proportions. Simon Hales and colleagues at the Wellington School of Medicine in New Zealand believe that the occurrence of dengue fever in South Pacific islands could have been the result of regional climate changes, which depend …
in view of a recent discovery, the models used to estimate earth's response to climate change stand for a rethink. While studying the effect of marine life on global warming, scientists found that the role of oceans in carbon fixation had actually been overestimated. The new findings suggest that half …
it could take something as simple as iron supplements to combat the spectre of global warming. It was John H Martin, an ocean scientist who had first suggested that fertilising the seas with thousands of tonnes of iron compounds could result in the sudden spurt of marine plant organisms called …
spring reaches the northern hemisphere a week earlier than it did twenty years ago. Charles Keeling of the Scripps Institution of Oceanography at La Jolla, California, us , has recorded a sudden shift in the seasonal cycle of the concentration of atmospheric carbon dioxide, resulting in the early arrival of …
David Vaughan and Chris Doake, glaciologists with the Bristish Antarctic Survey have published a paper which states that atmospheric warming has caused the disintegration of five ice shelves in the Antarctic peninsula, over the last 60 years. The breaking down of the shelves has taken place in the warmest part …
One would that if more than 1,000 scientists belonging to various countries and working for 10 years, pointed out the grave danger posed by increasing carbon emissions to the climate as well as the global economy, world leaders would take notice and initiate restorative action. Instead, they choose to either …
Global climate change is today a spectre which allows for no ostriches. Scientific data is piling up to indict human activity as the source of the current phase of warming. The debate is whether the affluent North or the developing South has been more responsible and who will be polluting …
The Intergovernmental Panel on Climate Change's (ipcc) argument that current global warming "is unlikely to be entirely natural in origin' and that "the balance of evidence suggests a discernible human influence on global climate' throws light on certain pointers. The chief human influence on climate is the general warming effect …
