Description :

Understanding Global Climate Change: Climate is complex. This course provides participants with the background necessary to make sense of the news and to understand the science behind the climate change debate. We’ll also discuss how climate change deniers and conspiracy theorists use facts to undermine the truth of our current situation here on Planet Earth. This course is targeted for every person on the planet who is curious and wants to learn something new or a new way to think about our planet. This class is also for those who like to draw diagrams. This class is not for scientists. Suitable to high school students and older. Please Note: This course consists of eight weekly 1.5-hour sessions via Zoom or video recorded sessions only.

Meet our Instructor

Shifra Gassner, MA

This course is taught by Shifra Gassner. For the last five years, Shifra has been teaching a class called Earth Space Science to high school students in Iowa, USA. During this time she has honed in on what exactly a person needs in order to understand what is happening in the world right now in terms of global climate change. Many adults have asked about the subject matter she teaches. Only recently has Earth Science been taught at a high school level and a person may or may not have taken an Earth Science class while at University. What Shifra teaches is what a lot of people missed along the way during their formal education years. She feels strongly that with knowledge comes power and the motivation to act. She has taught many different levels and subjects over the past 20 years. She loves teaching science, especially the nature and process of science and loves nature. She spends a lot of her time outdoors painting landscapes whenever she can.

  1. 1
    • EarthDiverse Zoom instructions

  2. 2
    • In order to understand how climate is changing it is necessary to understand components that go into making the climate of a particular place. We will discuss these components in order to see how they impact and make the climate.

  3. 3
    • We are a carbon-based life form. Carbon is a very important part of life on Earth. We will diagram the movement of carbon throughout the hydrosphere, geosphere, atmosphere

  4. 4
    • Our atmosphere is a life-sustaining protection between us and the rest of space. It is important to know what gases compose our atmosphere, their relative proportion, their behaviour

  5. 5
    • What we know about changes on Earth comes from data that is collected around the world. We will look at the different ways in which data is collected and what it tells us about the changes taking place on Earth

  6. 6
    • Feedback loops are a way of understanding the nature of large systems. We will look back at the 10 recognized signs of global warming from the previous week to see

  7. 7
    • What is sustainability? How do we live on Planet Earth in a way that will promote the continuation of the environment, our economy, and equity into the future?

  8. 8
    • Here we look at the practices of biochar, carbon sequestering, and geo-engineering.

  9. 9
