CLIMATE CHANGE | 77<br />

Results of Current Climate Models<br />

Around the world, different teams of scientists have built <strong>and</strong> run models <strong>to</strong> project future climate conditions<br />

under various scenarios for the next century. The model results project that global temperature will continue <strong>to</strong><br />

increase, but show that human decisions <strong>and</strong> behavior we choose <strong>to</strong>day will determine how dramatically climate<br />

will change in the future.<br />

How are Climate Models Different From Weather Prediction Models?<br />

Unlike weather forecasts, which describe a detailed picture of the expected daily sequence of conditions starting<br />

from the present, climate models are probabilistic, indicating areas with higher chances <strong>to</strong> be warmer or cooler<br />

<strong>and</strong> wetter or drier than usual. Climate models are based on global patterns in the ocean <strong>and</strong> atmosphere, <strong>and</strong><br />

records of the types of weather that occurred under similar patterns in the past.<br />

IPCC (Intergovernmental Panel on Climate Change)<br />

The Intergovernmental Panel on Climate Change (IPCC) is the most prominent international scientific body<br />

for assessing climate change. It was formed in 1988 by the World Meteorological Organization (WMO) <strong>and</strong> the<br />

United Nations Environment Programme (UNEP). There are currently 195 member-countries in the IPCC,<br />

<strong>and</strong> membership is open <strong>to</strong> all countries in the WMO <strong>and</strong> UN. The IPCC is responsible for reviewing <strong>and</strong><br />

evaluating scientific, technical, <strong>and</strong> socioeconomic information related <strong>to</strong> climate change. While the IPCC<br />

neither conducts research nor moni<strong>to</strong>rs any climate change data directly, it provides policymakers with the most<br />

comprehensive picture of the scientific consensus.<br />
