Global warming is the name given to the fact that the world’s temperature has become hotter over the last two hundred years. Global warming may be a very serious problem for the world. It causes floods and storms.

Today, the atmosphere of the world is about a half a degree Celsius hotter than it was two hundred years ago. But many people disagree about whether this is caused by man’s pollution (from cars and factories, for example), or a natural change.

Global mean surface temperatures 1856-2004The average temperature at the surface of the Earth has gone up by 0.6°C since the late 19th century[1]. This is known as Global warming. There are several theories which try to explain this increase. Most of the warming of the last 50 years is believed to be a result of increases in the greenhouse effect caused by human-generated carbon dioxide (CO2); variations in the amount of heat from the sun and other natural causes also play a role.

Climate models predict that temperatures will increase by 1.4°C - 5.8°C between 1990 and 2100 [2]. Much of the uncertainty in this increase results from not knowing future CO2 emissions, but there is also uncertainty about the accuracy of climate models. Climate commitment studies predict that even if levels of greenhouse gases and solar activity were to remain constant, the global temperature will increase by 0.5°C over the next one hundred years due to the lag in warming caused by the oceans.

Although the discussion of global warming often focuses on temperature, global warming or any climate change[3] may cause changes in other things as well, including the sea level, precipitation, weather patterns, etc. These may affect human activity via floods, droughts, heat waves, changes to agricultural yields, etc.
