Climate and Climate Change. Climate Climate is the average weather conditions in an area over a long period of time. Climate is determined by a variety.
Changes in solar radiation are primary cause for climates to change ~10% change in solar radiation output can dramatically alter Earth’s climate Changes.
 The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate.
