New 3D View of Methane Tracks Sources

NASA’s new 3-dimensional portrait of methane shows the world’s second largest contributor to greenhouse warming as it travels through the atmosphere. Combining multiple data sets from emissions inventories and simulations of wetlands into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas and its role in Earth’s carbon cycle,…

COVID-19: Economic slowdown doesn’t stop climate change

Credit: CC0 Public Domain Efforts to control the coronavirus pandemic have reduced economic activity and led to localized improvements in air quality. But it is too early to assess the implications for concentrations of greenhouse gases which are responsible for long-term climate change. Carbon dioxide levels at key observing stations have so far this year…

Could synthetic fish be a better catch of the day?

Image copyright Sterling Caviar Image caption More caviar might have to come from farmed sturgeon Overfishing has depleted numbers of wild fish, and fish farms meet much of the growing demand. Could we one day be eating “fish” grown from cells in a factory, as a number of start-ups are planning?”Caviar is no longer a…

World Made By Hand is a post-pandemic world novel

(I originally reviewed this in 2008, but thought it was worth reposting, for obvious reasons. — MF) In World Made By Hand (2008) by James Howard Kunstler, the population of the United States (and most likely, the world) has been decimated by an energy shortage, starvation, plagues, terrorism, and global warming. The story takes place…

Simple framework helps future ocean studies

The team anticipates that their framework will provide a strong base to help improve the robustness and reproducibility of the growing body of research in different marine environments. Credit: Nathan Geraldi A range of information is collated through a simple framework that will help marine scientists to design more accurate experiments that will better help…

Climate change: Earth’s deepest ice canyon vulnerable to melting

Image copyright NASA/J.Sonntag Image caption Other space data indicates Denman shed 270 billion tonnes of ice between 1979 and 2017 East Antarctic’s Denman Canyon is the deepest land gorge on Earth, reaching 3,500m below sea-level. It’s also filled top to bottom with ice, which US space agency (Nasa) scientists reveal in a new report has…
