How climate change and air pollution can affect your health

From ABC News — Written by Gillian Mohney

President Donald Trump’s decision to pull out of the landmark Paris climate agreement could have far reaching consequences on climate and fossil fuel emissions in the future.

While climate change and pollution are often discussed in terms of environmental damage, they can also greatly impact public health.

Under the Paris agreement, the U.S. said it would cut carbon emissions by 26-28 percent from 2005 levels by 2025 and parties agree to try to hold global temperatures to no more than 2 degrees Celsius above temperatures in the late 1800s.

Jeffrey Shaman, director of the Climate and Health Program at the Mailman School of Public Health, pointed out that a changing climate may mean fundamental changes to human health.

Acquiring and using fossil fuels “has led to the disruption of the [climate] system that we have come to rely on,” said Shaman pointing out civilization developed during the 11,000 year period of climate stability. “That disruption is a fundamental stressor on our system.”

Without that climate stability, Shaman and other public health officials have found that there are risks to public health from multiple factors including extreme weather, spreading populations of insects and irritating airborne pollutants.
