Aaron Sidder is a freelance writer based out of Denver, Colo. He has a master’s degree in ecology from Colorado State University. Aaron was an AGU-sponsored AAAS Mass Media Science & Engineering Fellow at National Geographic in 2016, and he has been writing for Eos ever since. In addition to Eos and National Geographic, he has written for National Geographic Kids Magazine, Smithosonian Smart News, 5280 Magazine, and the Santa Fe Institute. In his free time, he cultivates an extensive—and growing—collection of field guides from around the country.
Many oceanic properties are not directly observed but are instead estimated using proxy measurements. A new method uses physics-based correlations to reduce uncertainty in this relationship.Read More »Atmospheric Sciences
Rapid temperature spikes in the stratosphere above Antarctica can influence weather and spark cyclones in the Northern Hemisphere’s tropics.Read More »Climate Change
El marco teórico que estudia los límites planetarios define cuánta perturbación humana pueden soportar los diversos procesos del sistema terrestre, pero puede que no describa adecuadamente el ciclo del agua o la medida en que lo hemos alterado.Read More »Climate Change
Largely spared from disruptive tectonic activity, the South African coastline offers a natural setting to study sea levels from when Earth’s atmospheric carbon dioxide last reached today’s levels.Read More »Biogeosciences
Un nuevo modelo permitirá a los modelos climáticos interpretar mejor las reconstrucciones paleoclimáticas derivadas de sedimentos de lagos y podrá mejorar las predicciones de las condiciones climáticas futuras.Read More »Hydrology, Cryosphere & Earth Surface
Handprint thinking, a concept developed about a decade ago, is meant to complement ecological footprints and frame human actions in terms of how much good they can do to promote sustainability.Read More »Ocean Sciences
Videos from Twitter and YouTube helped scientists tease out the physical mechanisms that generated the large tsunami in Palu Bay after a magnitude 7.5 earthquake.Read More »Biogeosciences
Continental shelves and estuaries are natural sources of nitrous oxide, but current global estimates of these emissions carry a lot of uncertainty, a problem that calls for regional studies.Read More »Climate Change
The planetary boundaries framework defines how much human disturbance various Earth system processes can take, but it may not adequately depict the water cycle or the extent to which we’ve altered it.Read More »Hydrology, Cryosphere & Earth Surface
Signals in layers of sedimentary rock hint at climates and ecosystems come and gone. Understanding this history can help us forecast the future, but challenges abound.Read More »
