Global warming is that the ongoing rise of the typical temperature of the Earth's climate system and has been demonstrated by direct temperature measurements and by measurements of varied effects of the warming. It is a serious aspect of global climate change which, additionally to rising global surface temperatures, also includes its effects, like changes in precipitation. The main balancing feedback to global natural process is radiative cooling to space as infrared , which increases strongly with increasing temperature. After an initial warming thanks to emissions of greenhouse gases, the atmosphere will hold more water. A climate model may be a representation of the physical, chemical, and biological processes that affect the climate system. Computer models plan to reproduce and predict the circulation of the oceans, the annual cycle of the seasons, and therefore the refore the flows of carbon between the land surface and the atmosphere. There are quite twenty-four scientific institutions that develop climate models.
