This overview sets the scene for the various modules in the Renewables 2024 Global Status Report Collection. It provides high-level trends on the status of renewables in the wider fossil fuel-dominated energy system in the context of global challenges such as climate change, development goals and the geopolitical landscape. Urgent …
With the world increasingly worried about climate change, a new scheme is being cooked up to deal with the problem. The World Bank has an ingenious proposal - which is still confidential - in which the Bank would buy and sell, as the most "honest broker", the rights of present …
A US study shows that increasing concentrations of carbon dioxide (CO 2 ) in the atmosphere result in improved photosynthesis, helping trees grow faster. Scientists at the University of Georgia, USA, have evaluated the response of loblolly pines to increasing concentrations of CO 2 and measured the photosynthesis, respiration and …
the cement industry has a larger share in global emissions of carbon dioxide ( co 2 ) than that of aircraft worldwide, estimates an industry scientist. It contributes about seven per cent of the global co 2 output. This puts it in the third place in the list of contributors …
the latest thing that is brewing up a storm in Europe is a new self-cooling drink can which could cause global warming. Britain is now seeking new ways to ban the can. "If the can captures, say 10 per cent of the uk market by the year 2000, it would …
A survey of 10,076 households conducted by the NPD Group Inc in the US found that computers switched on at homes sit idle for 54 per cent of the time. The Sierra Club, a group of environmentalists, has estimated that a computer running for more than three hours a day …
Forests help maintain the environmental conditions that make life possible, from regional hydrologic cycles to global climate. Frontier forests, large, ecologically intact and relatively undisturbed natural forests, are particularly important as they store tremendous amounts of carbon. Without these forests, this carbon would go straight into the atmosphere as carbon …
More than 80 per cent of carbon dioxide (CO2) emissions are caused by industrial activity - burning of fossil fuels, such as oil, gas and coal, and cement manufacturing, which creates CO2 during limestone processing. Industrial emissions of CO2 have more than tripled in the past 40 years, prompting fears …
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 …
Monitoring the effect of rising carbon dioxide (CO) concentrations and climatic changes on Europe's forests is the aim of a collaborative project across eight European countries and Australia. The project is jointly funded by the Forestry Commission of UK and the European Union under the Environment and Climate Programme 1994-1998. …
THE Japanese cabinet recently approved an energy-conservation programme which aims at making drastic reductions in carbondioxide (CO2) emissions. The energy package includes 66 plans including one which would restrict the number of cars allowed into heavy traffic zones. The plan seeks to achieve zero growth in energy consumption by the …
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, …
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 …
the role of the Dutch as pioneers in international environmental policy seems to have been relinquished. The question of reducing carbon dioxide (co2) emissions to three per cent below the 1990 levels by the year 2000, is under debate in the Netherlands. Although climate change was a hot issue in …
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)
Researchers at Tokyo Metropolitan University in Japan have developed a material which can be attached to chimneys of power plants and factories to remove carbon dioxide (CO 2 ) from emissions and help protect against global warming. This material, a sieve-like membrane which can selectively remove CO 2 from mixed …
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 …
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 …
