The greenhouse effect is the heating of the surface of the planet due to the presence of an atmosphere containing gases that absorb and emit infrared radiation, this gases are call greenhouse gases ,some Common greenhouse gases in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

The effects of the greenhouse effect are of concern both for theenvironment and human life. Scenarios studied by the Intergovernmental Panel on Climate Change (IPCC) predict that global warming will continue and get worse much faster than it was expected even intheir last report, Research by NOAA indicate that the effects of global warming are already largely irreversible.

The IPCC reports attribute many specific natural phenomena to human causes. Theexpected long range effects of recent climate change may already be observed. Rising sea levels, glacier retreat, Arctic shrinkage, and altered patterns of agriculture are the consequences of our actions.Predictions for secondary and regional effects include extreme weather events, an expansion of tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact.The most direct effect of climate change on humans might be the impacts of hotter temperatures themselves. Extreme high temperatures increase the number of people who die on a given day for manyreasons: people with heart problems are vulnerable because one's cardiovascular system must work harder to keep the body cool during hot weather, heat exhaustion, and some respiratory problemsincrease. Global warming could mean more cardiovascular diseases, doctors warn. Higher air temperature also increase the concentration of ozone at ground level. In the lower atmosphere, ozone is a harmfulpollutant. It damages lung tissues and causes problems for people with asthma and other lung diseases.

The continued retreat of glaciers will have a number of different effects.
