Effects of Global Warming


There are many effects of global warming. The main effect is an increase in the average temperate of the earthair. Added to that, rising sea level will have a bad impact on agriculture. Global warming causes some infectious diseases such as malaria. It causes many natural disasters,for example, droughts, floods and storms. Evaporation is increasing due to warmer oceans. Global warming could reduce the ocean's ability to absorb CO2.It also makes some changes in the ecosystem. Rising global temperature might cause forest fires. Then, global warming has effects on the ground so roads, airport runways, railway lines and pipelines will need a maintenance renewal much more often. Higher temperatures will also increase the demand for water for the purpose of cooling.
