A new way to fight climate change: Trap carbon dioxide in volcanic rocks

Climate change refers to the fluctuation of the climate system caused by the energy entering and leaving Earth. The greenhouse effect, which refers to how greenhouse gases (GHGs) act like a blanket and prevent the loss of Earth’s heat to space, has occurred naturally throughout Earth’s history. However, since the Industrial Revolution, human activities have […]

Major advance in artificial photosynthesis uses sunshine to create fossil fuel analogs

A major breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions and convert them into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels. Developed by scientists from the Lawrence Berkeley National Laboratory and the University of California Berkeley, the system uses […]

Rising CO2 causing nutritional content of crops to fall

Field tests by University of California – Davis scientists have shown conclusively that rising levels of carbon dioxide inhibit plants’ ability to assimilate nitrates into proteins. The findings, published in the journal Nature Climate Change, indicate that the nutritional quality of food crops such as wheat, barley, rice, and potatoes is at risk as climate […]

Oceanic food-chain undergoing dramatic changes

Increasing levels of carbon dioxide appear to be changing the biodiversity of the oceanic ecosystem, most notably the keystone bacterial organisms that form the foundation of the ocean’s food-chain. Reporting their findings in Nature Geoscience, the researchers say they are uncertain as to what the long term effects of these climate-driven selection pressures will be. […]

“Green” biofuels anything but

A detailed new study on greenhouse gas emissions from oil palm plantations has calculated a more than 50 percent increase in levels of carbon dioxide emissions than previously thought – and warns that the Western world’s demand for “green” biofuels could be costing the Earth. The findings, by researchers at the University of Leicester (UK), […]

CO2 Rocketing, Carbon Sinks Failing

Man’s activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening, suggests a new study in the Proceedings of the National Academy of Sciences. The report states that “together, these effects characterize a carbon cycle that is generating stronger-than-expected climate […]
