Climactic changes, especially global warming, are potentially the largest global threat to human health and the source of the greatest number of cases of disease. If current emissions and land use trends continue unchecked, future generations will face more serious conditions, including injury, disease, and death related to natural disasters and heat waves, higher rates of climate-related infections, widespread malnutrition, and more allergy and air pollutionrelated morbidity and mortality. This review highlights the relationship between global climate changes and human health and provides some suggestions for improvement. According to the Fourth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC) published in 2007, global warming is caused by greenhouse gas (GHG) emissions. The most important GHG is carbon dioxide (CO2), which is released by the burning of fossil fuels and, to a lesser extent, by land use practices, followed by nitrous oxide and methane. IPCC predicts that global temperatures will rise 1.8degrees C-4.0degrees C by 2099. According to the report, we can expect a significant rise in sea levels, massive species extinctions, changes in storm and drought cycles, altered ocean circulation, and redistribution of vegetation after crossing the "tipping point" of global warming. Human health will be adversely affected by the accelerating climate change. This review stimulates health care providers to provide quality care to susceptible individuals confronting new threats from climactic changes, as well as to work toward a mitigation of the drivers of climate change at the individual, community, and policy levels as part of a long-term commitment to protecting public health.

The average temperature of the Earth's near-surface air and the oceans has increased 0.74 +/- 0.18degrees C over the last century. Climate change can cause sea levels to rise, change the amount and pattern of precipitation, shrink the cover of rain forest and forest, increase the intensity of extreme weather events, and cause species extinctions and changes in agricultural yields. Many human diseases, such as cardiovascular diseases, allergies, respiratory diseases, and infectious diseases, are related to climate fluctuation. Climate change can cause the level of air pollutants to increase and affect the interaction of air pollutants and respiratory allergens. Ambient air pollutants such as nitrogen dioxide, ozone, particulate matter, volatile organic compounds, and sulfur dioxide have been linked to allergic diseases and asthma. Here, the effect of climate change and air pollution on health outcomes such as asthma and allergic diseases is reviewed.
