Environment and Climate Change

Objectives 1. Form definitions of the climate changed based on prior knowledge, class discussion, and viewing diagrams. 2. Participate in group brainstorming sessions and class discussions related to the impact of the greenhouse effect and global warming. 3. Analyze ice/icebergs on film to obtain a clear understanding of the scientific process of climate change. 4. Understands global development and environmental issues

What are Greenhouse Gases?  Many greenhouse gases occur naturally, such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Others such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) result exclusively from human industrial processes.  Human Activities and Greenhouse Gases.  Human activities also add significantly to the level of naturally occurring greenhouse gases: Carbon dioxide is released into the atmosphere by the burning of solid waste, wood and wood products, and fossil fuels (oil, natural gas, and coal). Nitrous oxide emissions occur during various agricultural and industrial processes, and when solid waste or fossil fuels are burned. Methane is emitted when organic waste decomposes, whether in landfills or in connection with livestock farming. Methane emissions also occur during the production and transport of fossil fuels.

Freewrite Take five minutes to respond to the following: Today, most scientists agree that Earth's temperature has risen over the past century and that carbon dioxide is one of the primary greenhouse gases that contribute to global warming. Disagreement persists, however, over whether or not global climate change is a normal environmental variation, and over how big of a problem global warming could become for the planet. What kind of impact do you make on the environment? Whose responsibility do you think it is to take care of the planet?

Chasing Ice EEJ Focus Question: How has the use of greenhouse gases impacted the environment? While you watch the clips from the documentary, look for five examples for your EEJ’s.
