Climate change is a global threat that is already having a significant impact on human health. The effects of climate change, such as extreme heat, air pollution, and infectious diseases, are disproportionately harming the most vulnerable populations, including the poor, the elderly, and those with underlying health conditions.

Extreme heat is one of the most immediate and dangerous health threats posed by climate change. Heat waves can lead to heatstroke, heat exhaustion, and other heat-related illnesses, which can be fatal, especially for the elderly and people with chronic health conditions. In addition, extreme heat can worsen existing health conditions, such as asthma, heart disease, and kidney disease.

Air pollution is another major health threat linked to climate change. Warmer temperatures and changing weather patterns can lead to increased levels of ground-level ozone and other air pollutants. Air pollution can cause a range of respiratory problems, including asthma, bronchitis, and lung cancer. It can also worsen heart disease and other cardiovascular conditions
