AJPH supplement focuses on how climate change impacts public health

In the American Public Health Association's Year of Climate Change and Health, the American Journal of Public Health will release a special supplement focused on climate change and its effect on public health.

This collection of editorials and research articles examines how climate change impacts our health and discusses how the public health community and policymakers can respond to this threat:

Planting more trees in cities can prevent deaths from heat

Researchers examined heat-related deaths caused by the urban heat island effect in Ho Chi Minh City. They found that deaths from the urban heat island effect accounted for 30% of the total mortalities from heat in the city. The study also found that every increase in green space by 1 square kilometer per 1000 people can prevent 7.4 mortalities resulting from heat.

Non-US citizens at higher risk of heat-related death

Researchers compared heat-related mortality in non-U.S. citizens to that of U.S. citizens. They found that heat-related deaths accounted for 2.23% of deaths among non-U.S. citizens and 0.02% of deaths among U.S. citizens. Data also showed that non-U.S. citizens aged 18 to 24 were 20 times more likely to die from excessive heat exposure than were U.S. citizens. 95% of non-U.S. citizen heat-related deaths occurred in Arizona, California and Texas. The study found an increased mortality risk among non-U.S. citizens compared with U.S. citizens for heat-related deaths, especially those younger and of Hispanic ethnicity.

US health care industry's greenhouse gas emissions will cause up to 381,000 years of healthy life lost

This study quantifies the increased disease burden caused by U.S. health care sector greenhouse gas emissions. In 2013, the health care sector emitted 614 million metric tons of carbon dioxide equivalents. Researchers projected that health care greenhouse gas emissions would cause 123,000 to 381,000 disability-adjusted life-years in future health damages, with malnutrition being the largest damage category. Researchers note that this data highlights the magnitude of greenhouse gas emissions associated with health care itself, and the severity of associated health damages.
