"The trillions of marine viruses that inhabit the world’s oceans could be mobilised in the fight against climate change. New studies suggest that manipulating the viruses that infect most of the bacteria in the oceans enables the microbes to absorb more carbon dioxide from the atmosphere, which could be employed to tackle global warming."

"Sustainable and continuous operation of an artificial photosynthetic (AP) system requires a constant supply of CO₂ captured from the dilute sources such as the flue gas and the air to make fuels and chemicals. Although the architecture of AP systems resembles that of the natural leaves, they lack an important component like stomata to capture CO₂ directly from the dilute sources. Here we design and evaluate the solar-to-fuel (STF) efficiency of the integrated AP system that captures CO₂ directly from the air/flue gas and converts it to fuels using sunlight."

"This study developed a bubbling-type photosynthetic algae microbial fuel cell (B-PAMFC) to treat synthetic wastewater and capture CO₂ using Chlorella vulgaris with simultaneous power production. The performance of B-PAMFC in CO₂ fixation and bioenergy production was compared with the photosynthetic algae microbial fuel cell (PAMFC) and bubbling photobioreactor. Different nitrogen sources for C. vulgaris growth, namely sodium nitrate, urea, ammonium acetate and acetamide were studied."

"Geoengineering refers to a broad set of methods and technologies that aim to deliberately alter the climate system on a sufficiently large scale to alleviate the impacts of climate change. While definitions and terminology vary, in line with recent scientific consensus this paper gives separate consideration to the two main approaches considered as geoengineering: Solar Radiation Modification (SRM) and large-scale Carbon Dioxide Removal (CDR)."
