This weekend, people all across the United States will be enjoying the last hurrah of summer, perhaps with a trip to the nearest swimming hole. But an influx of bathers, tubers, and paddle boarders could significantly change the composition of freshwater streams, according to new research published in ACS ES&T Water. “People are exposed to…
Source: Global Biogeochemical Cycles The goals outlined in the Paris Agreement on climate include limiting climate warming to below 2°C and reaching a global peak of greenhouse gas emissions as soon as possible. To meet these targets, scientists need comprehensive accounting of the greenhouse gases entering and leaving the atmosphere over different landscapes. Using the…

Something freaky happened to the Sun in the 17th century. Instead of the usual 11-year solar cycle of increasing and decreasing sunspot numbers, the Sun produced far fewer sunspots than normal from roughly 1645 to 1715. Because the Maunder Minimum (as it was later named) occurred toward the very beginning of the era of solar…

Remote and multihub conference setups have become more popular since the COVID-19 pandemic [Klöwer et al., 2020]. These adaptations, tailored to meet diverse community needs, not only reduce carbon emissions but mitigate fatigue from online participation [Kremser et al., 2024]. These conference formats offer the geosciences community in particular an opportunity to address the effects…

This is an authorized translation of an Eos article. Esta es una traducción al español autorizada de un artículo de Eos. La Tierra podría haber tenido agua dulce 500 millones de años antes de lo que se pensaba, de acuerdo con un nuevo estudio de diminutos granos de circón procedentes de Australia datados hace unos 4,000 millones de años. Según…
Editors’ Highlights are summaries of recent papers by AGU’s journal editors. Source: AGU Advances Air quality is a growing threat to public health, with risks expanding from the historic industrial areas of the Global North to the developing economies of the Global South. Increasing scientific understanding from the lab, process studies, and field campaigns has…

Editors’ Highlights are summaries of recent papers by AGU’s journal editors. Source: AGU Advances In their new study, Farinacci et al. [2024] add to the ongoing discussion of how carbon-water tradeoffs vary with forest age, and make two new contributions. First, by comparing experiments where individual trees are monitored in paired watersheds differing in past…

Source: Earth and Space Science Jupiter’s striking appearance comes from its stormy atmosphere. Swirling clouds surround the gas giant, and their distribution reflects the planet’s weather. Scientists have used professional observatories such as the Very Large Telescope in Chile (whose construction in the 1990s cost more than 330 million euro, or US$366 million) and spacecraft…
For more than 60 years, NASA’s Earth science missions have advanced our understanding of Earth systems and helped us monitor and manage environmental and climate change impacts such as droughts, deforestation, and flooding from extreme rainfall. NASA is shifting its approach to prioritize practical applications of its data from the outset in the design, selection,…

Editors’ Highlights are summaries of recent papers by AGU’s journal editors. Source: Journal of Advances in Modeling Earth Systems Radiative transfer (RT) in plant canopies is an important process to represent in land surface models. Canopy RT determines how much global solar energy is reflected (albedo) and how much is absorbed by canopy (foliage and…
