Anticipated impacts of climate change on women's health: A background primer

Due to human activities, atmospheric greenhouse gas levels have increased dramatically, leading to an increase in the global mean surface temperature by 1.1° Celsius. Unless we can achieve a significant reduction in emissions, the global mean surface temperature will continue to rise to a dangerous level. Adverse outcomes of this warming will include extreme weather events, a deterioration of food, water and air quality, decreased food security, and an increase in vector-borne infectious disease. Political and economic instability as well as mass population migration will result in reduced access to healthcare resources. Mitigation of and adaptation to climate change will be key determinants of humanity's survival in the face of this existential crisis. Women will be more adversely affected by climate change than men, and pregnant persons will be particularly vulnerable. Particular differential impacts on women include higher heat and particulate-related morbidity and mortality; pregnancy risks including preterm birth, fetal growth lag, hypertensive disorders; and mental health impacts. To prepare for the climate crisis, it is imperative for women's healthcare providers to assist their patients through political advocacy, provide family planning services, and focus on nutrition and lifestyle counseling.
