A climate model is essentially a representation of the many interactions within the climate which includes the atmosphere, oceans, land surface, and ice.
Climate models are typically quantitative in nature and range from simple depictions of the Earth’s climate to very complex ones.
In fact, scientists are using climate models to predict global temperature increases in the next few decades due to greenhouse gases.
Virtually all climate models will take into account the incoming visible light and infrared radiation from the sun as well as the outgoing infrared radiation (of longer wavelength) that is sent back into space.
In other words, although scientists disagree regarding the precise amount that temperatures will rise, the great majority of scientists do agree that anthropogenic global warming is a reality and a serious issue.« Back to Glossary Index
