Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air.
The primary cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere primarily carbon dioxide. Other human activities, such as agriculture and deforestation, also contribute to the greenhouse gases that cause climate change. Small increases in Earth’s temperature caused by climate change can have severe effects.

Because winter temperatures are rising faster than summer ones, cold-related deaths are likely to decline. Climate change could lead to even warmer temperatures in cities. This would increase the need for electricity in the summer to run air conditioning, which in would increase air pollution and greenhouse gas emissions from power plants. The impacts of future heat waves could be especially severe in urban areas. For example, in Los Angeles, annual heat-related deaths are projected to increase two- to seven-fold by the end of the 21st century, depending on the future growth of greenhouse gas emissions. Heat waves are also often accompanied by periods of stagnant air, leading to increases in air pollution and the associated health effects.
The frequency and intensity of extreme precipitation events is projected to increase in some locations, as is the severity of tropical storms. These extreme weather events could cause injuries and, in some cases, death. As with heat waves, the people most at risk include young children, older adults, people with medical conditions, and the poor. Extreme events can also indirectly threaten human health in a number of ways. Reduce the availability of fresh food and water, interrupt communication, utility, and health care services, Contribute to carbon monoxide poisoning from portable electric generators used during and after storms.
Ground-level ozone can damage lung tissue and can reduce lung function and inflame airways.
