Green Mountain Academy for Lifelong Learning (GMALL) welcomes Tim Wheeler to talk about Earth’s atmosphere, which is largely invisible to us, yet is a defining trait of our planet and is essential to sustaining a stable environment on the surface. That life can thrive on earth is wholly dependent on the characteristics of the earth’s atmosphere. Join us on a journey of the mind through the five regions of the earth’s atmosphere. We will get a glimpse of odd and beautiful phenomena that occur above our heads as we discuss characteristics of these layers and how they protect us. We will visit the exciting vehicles that scientists have used to study near space over the past century and discuss why it is still quite mysterious to us despite its importance to the survival of a highly evolved and vigorous biome on the surface of the earth. Registration for the talk is $22 per person in advance. For more information or to register, please call 802-867-0111 or visit our website at greenmtnacademy.org.
