Scientists from around the world with the Intergovernmental Panel on Climate Change (IPCC) tell us that during the past 100 years, the world's surface air temperature increased an average of 0.6 Celsius (1.1 F). This may not sound like very much change, but even one degree can affect the Earth.
Climate can affect day-to-day activities, health, agriculture and the environment in which we live. Energy sources can also be affected by changes in the climate. Most people structure their day-to-day activities around the current climate. Climate changes affect society by impacting various social, cultural and natural resources. For example, infrastructure, transportation systems, energy, food, and water supplies are all affected by climate change. The climate also affects economic activities and services.
