Inhaling particulate matter is hard on human health. New research shows that Southern California’s Santa Ana winds can clear or exacerbate fine-particulate pollution depending on wildfire conditions.Read More »Space Science & Space Physics
A new analysis of spacecraft data collected near the tip of Earth’s magnetotail sheds light on how geomagnetic activity affects the motion of electrons in this region.Read More »Biogeosciences
Wildfires can destroy large tracts of vegetation. But their smoke plumes may help crops and other plants use sunlight more efficiently.Read More »Climate Change
Researchers used a sediment core from a lake in California’s San Bernardino Mountains to track the effect of climate on vegetation, fire, and erosion between about 120,000 and 15,000 years ago.Read More »
Oxygen isotope ratios in cave deposits reflect past climates, but interpreting these data is not straightforward. A new study explores what these ratios really tell us.Read More »
Climate models that do not account for anaerobic microbial activity may underestimate future expansion of oxygen-depleted waters.Read More »Ocean Sciences
Large-volume volcanic eruptions can create instabilities in the ground above magma chambers, leading to massive collapses and telltale calderas.Read More »Hydrology, Cryosphere & Earth Surface
High nutrient concentrations cause water quality problems in lakes, and as the climate warms, these issues will only get worse. A new model assesses future scenarios and explores solutions.Read More »
