CI = Carbon Intensity (GHG per Joule) - source of energy Coal emits the most CO2 per joule of energy produced How does their albedo differ? Know their different types, such as positive and negative feedback loops. hm8?vu8H/Q .$(VMI3F a@"SH/9"n``?r0s"E"O'YB@7$. ), all frozen landscapes (arctic tundra, icebergs, glaciers, etc. Instead, it is determined by the temperature of the lower atmosphere and surface through a physical relationship known as the Clausius-Clapeyron equation, named for 19th-century German physicist Rudolf Clausius and 19th-century French engineer mile Clapeyron. Clouds can reflect about a third of the sun's light back into space. If you have questions about how to cite anything on our website in your project or classroom presentation, please contact your teacher. A good example is the General Circulation Model, which uses equations for physical laws to control the circulation of the atmosphere. Ask students to think about how each piece of the system affects other pieces of the system. This process of weathering is thus a sink for atmospheric carbon dioxide, which is an important greenhouse gas. This is because terrestrial and aquatic plants absorb a lot of the sun's heat to conduct photosynthesis. In this model, clouds caused the temperature to decrease. It is actually often the opposite; that the negative feedbacks are what produce balance in the Earth System, whereas the positive feedback loops can act like a runaway train. May or may not become more intense as global warming progresses. layers of gases surrounding a planet or other celestial body. In Activity 4, they discover how light-colored surfaces, such as snow, ice, and some clouds, have a cooling effect on Earth's temperature. -geoengineering, potential to mess stuff up, "the process of trapping carbon dioxide produced by burning fossil fuels or any other chemical or biological process and storing it in such a way that it is unable to affect the atmosphere.". These secondary changes are called climate feedbacks, and they could more than double the amount of warming caused by carbon dioxide alone. This video shows these changes. . National Geographic Society is a 501 (c)(3) organization. If Earths climate is colder and there is more snow and ice on the planet, more solar radiation is reflected back out to space and the climate gets even cooler.
