High clouds tend to trap heat and have a warming effect.
Scientists need to learn more about clouds to improve the accuracy of climate models. Drought Climate models predict that summer droughts might result from more evaporation and shifting rainfall patterns. In some areas of the world global warming could also cause snow and ice to melt early, reducing summer water supplies. Many miles of low-lying coastal land could be lost to flooding. Heavy Rains Global warming may lead to more frequent periods of intense rain in some areas.
