It’s possible for volcanoes to have a short-term impact on the climate – including global temperature cooling – due to the gases they inject high into the upper atmosphere. But Mount Ruang’s influence on the climate will likely be minimal, according to Greg Huey, professor and chair of the School of Earth and Atmospheric Sciences. And the day-to-day weather conditions near Mount Ruang in Indonesia – things like temperature, clouds and rain – probably won’t be influenced by the volcano for long, Huey told CNN. “The ash itself is short-lived in the atmosphere because it’s heavy, it’s big and it tends to settle out quickly,” Huey told CNN. It’s the gases that are able to reach much higher in the atmosphere. (This story also appeared at WRAL.)

Recent studies show nearly half of the world’s species are on the move because of the changing climate and habitat disruption. Apart from slowing fossil fuel production and prioritizing carbon storage, a direct solution for species inching north as temperatures rise is improving climate connectivity, a term likely coined by researchers from the Georgia Institute of Technology in a 2016 study. The idea builds on the established science of wildlife corridors and land conservation that supports the migration of animals. School of Earth and Atmospheric Sciences Assistant Professor Jenny McGuire, who worked on the study, said this kind of movement differs from traditional migration patterns. Instead of departing annually and returning, species are permanently moving to areas they’re finding more hospitable. “They’re moving in such a way that they’re tracking the climates they’re suited to live in or able to live in, and then staying in those places,” McGuire said.

Northern peatlands store approximately one-third of Earth’s terrestrial soil organic carbon due to their cold, water-saturated, and acidic conditions, which slow decomposition. To learn more, researchers — including School of Biological Sciences and School of Earth and Atmospheric Sciences Professor Joel Kostka — leveraged the SPRUCE experiment, where scientists can combine air and peat warming in a whole-ecosystem warming treatment. Peatlands build carbon stocks over centuries, but rising temperatures and atmospheric carbon dioxide concentrations rapidly changed the equilibrium at SPRUCE within a 4-year timescale, highlighting the vulnerability of these carbon-rich ecosystems to global climate change.

Ocean waters are constantly on the move, traveling far distances in complex currents that regulate Earth's climate and weather patterns. How might climate change impact this critical system? Oceanographer, College of Sciences Dean, and Betsy Middleton and John Clark Sutherland Chair Susan Lozier dives into the data in her TED Talk. Her work suggests that ocean overturning is slowing down as waters gradually warm — and her talk takes us on board the international effort to track these changes and set us on the right course while we still have time.
