New research shows increased temperatures and carbon dioxide levels are a threat to the Australian national icon, the koala.
Professor Ian Hume, Fellow of the Australian Academy of Science, and his students from the University of Sydney have been researching the effects of CO2 increases and temperature rises on eucalypts.
A new company hopes drivers will kick the oil habit by brewing ethanol at home that won’t spike food prices.
E-Fuel Corp unveiled on Thursday the “MicroFueler” touting it as the world’s first machine that allows homeowners to make their own ethanol and pump the brew directly into their cars.
HIGH gasoline prices could lead to a dramatic saving in US greenhouse-gas emissions. That’s the conclusion of economists in the US, who suggest high fuel prices are turning consumers off SUVs and onto smaller, more fuel-efficient vehicles.
What’s more, car owners are predicted to cut back on driving in order to save money. Together, these changes in consumer behaviour could make an important dent in the US contribution to global warming, reducing annual carbon dioxide emissions by tens of millions of tonnes per year. The impact will be dramatic, says Chris Knittel, an economist at the University of California, Davis, who was involved in one of the studies.
This summer’s Beijing Olympics will be “basically” carbon neutral thanks to a series of energy saving measures such as the use of solar power and an afforestation program, a senior official said on Thursday.
Technology Minister Wan Gang said that the event was expected to generate 1.18 million tonnes of carbon, in part because so many athletes and spectators were traveling long distances.
The aviation industry’s failure to curb its soaring carbon emissions could lead to the “worst case scenario” for climate change, as envisaged by the United Nations.
An unpublished study by the world’s leading experts has revealed that airlines are pumping 20 per cent more carbon dioxide into the atmosphere than estimates suggest, with total emissions set to reach between 1.2 billion and 1.5 billion tonnes annually by 2025.
