Geoengineering, an emerging technology aimed at counteracting the effects of human-caused climate change, also has the potential to counteract political polarization over global warming, according to a new study.

Read moreNearly all of the studies used to promote biofuels as climate-friendly alternatives to petroleum fuels are flawed and need to be redone, according to a researcher who reviewed more than 100 papers published over more than two decades.

Deep cuts in greenhouse gas emissions, while necessary, may not happen soon enough to stave off climate catastrophe. So, in addition, the world may need to resort to so-called geoengineering approaches that aim to deliberately control the planet's climate. That's according to a National Research Council committee that today released a pair of sweeping reports on climate intervention techniques.

Read moreThe United States saw continued growth in renewable energy, natural gas and energy efficiency in 2014, according to the third annual Sustainable Energy in America Factbook. The Factbook shows that U.S. deployment of sustainable energy increased as prices continued to fall and that investment in U.S. clean energy grew at a higher rate.

A novel class of materials that enable a safer, cheaper, and more energy-efficient process for removing greenhouse gas from power plant emissions has been developed by a multi-institution team of researchers. The approach could be an important advance in carbon capture and sequestration (CCS).

Read moreClean technology support can to some extent make up for weak CO2 pricing and hence help keep the two degrees target within reach, a new study shows. Even if the world climate summit in Paris later this year is successful in striking a climate deal, it might not bring about sharp greenhouse-gas cuts in the near-term. However, emission targets could be strengthened by complementary policies.

One of the major drawbacks of carbon-fueled battery cells is the intrinsic presence of CO2, which impedes CO oxidation and, therefore, lowers the energy density of the cell. Researchers describe a novel dual-phase ion-conducting ceramic membrane that is absolutely gas-tight but highly permeable for CO2.
