Some Summer Storms Spit Sooty Particles into the Stratosphere - Eos
Earth’s typically pristine stratosphere is filling with particles from wildfires and additional moisture due to strong convective storms.
eos.org
Some powerful summer storms can “overshoot” Earth’s troposphere, sending clouds up into the usually stable and pristine stratosphere. In the process, these clouds are bringing moisture and particles from wildfire smoke, too. 🧪🔥☁️

The "nutritional value" of glacial runoff is changing. Researchers found meltwater from retreating glaciers delivers sediment with lower concentrations of usable iron and manganese to coastal ecosystems. 🧪
Glacier Runoff Becomes Less Nutritious as Glaciers Retreat - Eos
Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.
