We will have a full slate of three talks. Join us to learn about climate change & air pollution, solar geoengineering, and the role of the US Geological Survey from its new director. Abstracts for the talks are here. Non members are always welcome, and there is no formal dress code for the audience. Details of the talk, including the Zoom link, will be sent to members shortly. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.
Doug Wicks of the U.S. Department of Energy will present "Addressing the Mineral Abyss for the Energy Transition." Doug is with the Advanced Research Projects Agency-Energy. @ARPAE advances high-potential, high-impact energy technologies. @ENERGY

Happy Birthday @USGS! ⛰️💧🪨🌋🗻
Got a a chance to hold a cast of the mandible or lower jaw of Spinosaurus at the new Sereno Fossil Lab of @UChicagoBSD. I keep forgetting how massive Spinosaurus was! #Dinosaurs #Paleontology #FossilFriday
Do other planets have leap years?
Yes! Leap years happen because a planet’s orbit around the Sun (year) and rotation on its axis (day) are not perfectly in line. This is true of almost every other planet in our solar system.
Are leap years really that important?
Leap years are important so that our calendar year matches the solar year. For example, say July is a warm, summer month where you live. If we never had leap years, in a few hundred years, July would take place in the cold winter months!
