Photosynthesis is a natural phenomena (used by plants, algae and many Bacteria species) to convert CO2 from the atmosphere into sugars (food) and O2 in presence of sunlight. In this way about 100 billion tons of CO2 is converted into biomass every year, for which 100 terawatts of energy is consumed which is not as efficient as per our energy requirement. For decades researchers have been trying to find efficient ways to use solar energy plus carbon dioxide from the atmosphere to create biofuels. … Read ahead

Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new Stanford study. But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice from melting. If soot emissions were eliminated, more than 1.5 million premature deaths from soot inhalation could be prevented worldwide each year. … 
When thinking of air pollutants many people instantly assume that carbon monoxide or carbon dioxide are the most lethal gases; however, recent studies show that an increase in mercury in the air can also be fatal. Most people don’t really think … 
The bicycle has many attractions as a form of personal transportation. It alleviates congestion, lowers air pollution, reduces obesity, increases physical fitness, does not emit climate-disrupting carbon dioxide, and is priced within the reach of the … 
New devices could capture greenhouse gas and provide CO2 for commercial uses, all in one pop Carbon dioxide is one of the most plentiful gases in the atmosphere, but when soda makers want to inject the fizz into their sweet-tasting drinks, they often … 
IFPRI. Global agriculture, he said, could adapt to climate change for about $7 billion annually, with most of the resources being devoted to research, new irrigation techniques and training small farmers for rises in sea level. Agricultural management directly affects how the three major greenhouse gases — carbon dioxide, methane and nitrous oxide — are cycled through the environment. According to … 
Sperm whale waste isn’t much to look at — a diarrhea-like substance with a few squid beaks floating around — but new research has found it removes carbon from the atmosphere, helping to offset greenhouse gases that have been tied to global warming. … 
In a sharp change from its cautious approach in the past, the National Academy of Sciences on Wednesday called for taxes on carbon emissions, a cap-and-trade program for such emissions or some other strong action to curb runaway global warming. Such actions, which would increase the cost of using coal and petroleum â at least in the immediate future â are necessary because “climate change is occurring, the Earth is warming … concentrations of carbon dioxide are increasing, and there are very clear fingerprints that link …
