“Prehistoric polar forests were built for survival, but were not hardy enough to live in ultra-high concentrations of atmospheric carbon dioxide. A geologist is studying the tree fossil record in Antarctica from a mass extinction 250 million years ago, looking for clues to how greenhouse gases affected plants — then and now.” By the trip’s… Read more
“Sedimentary layers record the history of Earth. They contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia, thereby enhancing our ability to understand and predict the evolution of our planet. Researchers at the University of Geneva (UNIGE), Switzerland, — together with colleagues at the… Read more
Atmospheric carbon dioxide (CO2) and methane (CH4) come from a variety of natural and anthropogenic sources and have a powerful global warming impact. Understanding the magnitude and distribution of these emissions spatially and temporally is critical to evaluating present and future climate impacts. Stable isotope signatures of methane and carbon dioxide are often employed to investigate the relative… Read more
“Typically, nitrogen is delivered to the well site as a refrigerated liquid that is gasified prior to injection and then is injected into the well to enhance recovery. As the primary component of the air we breathe, the benefits of nitrogen include it being inert, environmentally friendly, non-flammable, and when gasified, exhibiting very low densities… Read more
