Slides For Climate Class 1

This document provides an overview of climate change concepts including: - Climate change occurs when the energy balance is perturbed by changes in greenhouse gases or aerosols from human activities like burning fossil fuels. - The major greenhouse gases are carbon dioxide, methane, and nitrous oxide which are emitted through human activities such as burning fossil fuels and land use changes like deforestation and agriculture. - The carbon cycle regulates the flow of carbon among the atmosphere, oceans, terrestrial biosphere and geological reservoirs. Changes in the carbon cycle affect atmospheric CO2 levels.
