Methane leaks from palm oil wastewater are climate concern, CU-Boulder study says

Hana Fancher, Philip Taylor methane research palm oil wastewater ponds

In recent years, palm oil production has come under fire from environmentalists concerned about the deforestation of land in the tropics to make way for new palm plantations. Now there is a new reason to be concerned about palm oil’s environmental impact, according to researchers at the University of Colorado Boulder. An analysis published Feb. 26 in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere. But the researchers also present a possible solution: capturing the … [Read more...]

Amazonian drought conditions add carbon dioxide to the atmosphere

Amazon River through the rainforest

This article originally appeared on the University of Colorado Boulder website. As climates change, the lush tropical ecosystems of the Amazon Basin may release more of the greenhouse gas carbon dioxide into the atmosphere than they absorb, according to a new study published Feb. 6 in Nature. An international team of scientists found that the amount of yearly rainfall was the driving factor behind the amount of carbon dioxide (CO2) taken up and released from Amazonia in 2010 and 2011. During a wet year, the Amazon forests were roughly carbon-neutral: Forests “inhaled” more carbon … [Read more...]
