What is weather? Weather is a system of cycles and forces that are driven by the heat of the Sun, precipitation, and the lay of the land. Weather is measured and observed on a local scale.
What is climate? Climate is a system that takes into account wind regimes, sea-surface temperatures, rainfall patterns, and longitude and latitude zones. Climate is measured and observed on a large regional level.
Has the climate always been changing? Yes, just much more slowly than measured in recent decades. A factor that has to be taken into account for these mild changes over thousands of years is the physics behind the Milankovitch Cycles.
What does anthropogenic mean? ‘Anthro’, from the Greek anthropos, means human being while ‘gen’ means be produced; thus Anthropogenic means human produced. This term is mentioned many times throughout climate science and has been the backbone of the climate change debate.
