A new study finds two persistent mental shortcuts—not ignorance—are why people keep overrating recycling and underrating flying less.
Methane emissions from Siberia have more than doubled over the past decade, according to new research co-led by scientists at the University of Edinburgh’s National Centre for Earth Observation (NCEO)
Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress
Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration
World is approaching point where no one can shut down a rogue AI, says director of body behind research
The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.
Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older people
A team including scientists, Indigenous people and conservationists point to the ecosystem connecting Yellowstone and the Yukon as an example of a region where humans and nature are flourishing together.
Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation and adaptation actions). This paper describes the scenario framework for ScenarioMIP as part of CMIP7. The design process has involved various rounds of interaction with the research community and user groups at large. The proposal covers a set of scenarios exploring high levels of climate change (to explore high-end climate risks), medium levels of climate change (anchored to current policy), and low levels of climate change (aligned with current international agreements). These scenarios follow very different trajectories in terms of emissions, with some likely to experience peaks and subsequent declines in greenhouse gas concentrations in this century. An important innovation is that most scenarios are intended to be run, if possible, in emission-driven mode, providing a better representation of the Earth system uncert
Most research on “forever chemicals” focuses on how best to remove them from the environment. But solutions to tricky problems often emerge from the most unexpected of places—as demonstrated by a new study that instead redirects the pollutants into becoming tools for extracting precious lithium. In a recent Nature Water study, a team led by Rice University researchers describes a novel way to use spent perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to recover lithium from high-salinity brine pools. The team tapped into the fluorine content inside PFAS leftovers, using it to attract lithium from briny water. Remarkably, the team was able to collect lithium fluoride at 99% purity and confirmed that the sample was pure enough to boost the stability and performance of lithium-ion batteries.
