A recent study warns that some marine carbon dioxide removal methods, especially biological ones like ocean fertilization and macroalgae sinking, could significantly worsen ocean deoxygenation, potentially causing oxygen loss 4 to 40 times greater than current levels, highlighting the need for careful assessment and monitoring of these approaches.
Researchers have developed a method to convert carbon dioxide into methane using a nickel-based catalyst, potentially offering a more energy-efficient way to produce fuel from emissions. This process, which integrates carbon capture and conversion into a single step, could help close the carbon cycle by using renewable electricity, thus contributing to climate mitigation efforts. The study highlights the potential for developing more sustainable carbon capture technologies.
A recent study published in the journal Science suggests that the cooling benefits of planting trees may be overestimated, as darker forests can warm the Earth by reducing the albedo of the land they cover. Trees also release organic compounds that can react with oxidants, leading to a reduction in the destruction of methane and an increase in greenhouse gas concentrations. The study emphasizes the need for a more inclusive effort to mitigate climate change, including environmental management and lower energy-intensive consumption, to maximize the climate benefits of planting trees. Additionally, the focus should be on not only planting trees but also preserving current forests, as tree planting may make more sense for some areas than others.
Satellite imagery reveals that the East Coast, including major population centers like New York City, is sinking at rates between 1 and 2 millimeters annually, posing a serious threat to infrastructure and millions of people. The study emphasizes the need for proactive climate mitigation policies to address the impacts of land subsidence and prevent devastating consequences.
Researchers at Israel-based company Rewind have developed a new method of carbon storage by taking plants and biomass that have absorbed high concentrations of carbon dioxide and sinking them to the bottom of the Black Sea. Inspired by nature's ability to capture carbon, the researchers aim to achieve a net-negative effect by preserving the balance of carbon released when the plants decompose. The Black Sea's lack of oxygen creates an ideal preservation environment, preventing the carbon from reentering the atmosphere. This innovative approach could potentially remove 1 billion tonnes of carbon dioxide from the atmosphere per year, contributing to global climate change mitigation efforts.
