This assignment delves into the intricacies of climate change, beginning with an examination of Earth's energy budget and the roles of land, water, oceans, and the atmosphere. It identifies the three most impactful greenhouse gases—carbon dioxide, methane, and nitrous oxide—detailing their sources, global warming potentials, and contributions to the warming effect. The assignment then explores the human impact on the carbon cycle, highlighting how human activities have altered the carbon cycle and contributed to climate change. Furthermore, it investigates positive feedback loops within the environment, specifically focusing on the impact of the cryosphere and polar amplification, and the potential for emerging diseases from thawing permafrost. The assignment concludes with an analysis of climate change impacts on Canada, addressing factors related to water, agriculture/forestry, human health, urbanization, and northern community development.
