Use your smartphone to help NASA scientists protect the planet from the effects of climate change. Did you know that trees and climate are connected? Trees cool and moisten our air, fill it with oxygen, store carbon, create shade and habitats for other creatures, anchor the soil and slow the movement of water, and provide food, fuel, and building materials for human activities. All these factors are why NASA scientists study trees from the ground and from space. The data collected by volunteer scientists on the ground (like you!) can potentially be compared to the space-based tree height data. Scientists can use this data to help create global maps of land cover and forests. The data helps us understand how our planet is responding to a changing climate. At this week’s SciStarter LIVE! event, we’ll explore citizen science and SciStarter as we’re joined by a NASA science specialist from the GLOBE Observer: Trees citizen science project. Plus, we'll discover how your participation in this project can support THREE Girl Scouts programs on SciStarter: the Girl Scout Tree Promise, the Girl Scout Climate Challenge, and the Think Like a Citizen Scientist Journey. SciStarter LIVE! is a weekly event where you can join us on Zoom or watch the live stream on SciStarter’s Facebook page as we work through a citizen science project together. We’ll demonstrate the project and answer your questions. If you register, we will email you a link to the recorded event. Before the event, be sure to sign up for a SciStarter account at if you haven't already and have a look at the featured projects: GLOBE Observer: Trees: Girl Scouts on SciStarter: Girl Scouts Climate Challenge: Girl Scouts Tree Promise: See you on October 4th, 2022 at 2pm ET!
