Get there early if you want a seat (trust me!)
The air around us is made of up many things, including water, gasses, and aerosols. These aerosols, or tiny particles suspended in air, can come from natural sources or man-made pollutants. Often visible to the naked eye, they can have a huge effect on climate warming and cooling, and can dramatically affect the amount of solar energy that reaches the Earth’s surface. At this Science Pub we’ll talk about the optical properties of aerosols in our atmosphere, compare measurements taken in Houston and Sacramento, and discuss the effects of aerosols on our climate in general.
