1. CLIMATE CHANGE IS EXPECTED TO CAUSE MORE FREQUENT AND INTENSE EXTREME WEATHER EVENTS.

Extreme weather events - like floods, wildfires, and drought - can be terrifying, but what do they have to do with public health? These events can (of course – and unfortunately) have fatal consequences, but they can also lead to food and waterborne illnesses after the fact. Furthermore, if public infrastructure – like communication systems or emergency response services – is damaged during an extreme event, access to lifesaving care is jeopardized.

The report is also one of the first of its kind to study how climate change impacts mental health, noting that people “exposed to climate- or weather-related natural disasters experience stress reactions and serious mental health consequences, including symptoms of post-traumatic stress disorder (PTSD), depressions, and general anxiety.”

It’s also important to note that lower-income communities, children, the elderly, and some communities of color are disproportionately affected by extreme weather. Just as Pope Francis has said, “The deterioration of the environment and society affect the most vulnerable people on the planet.”

2. CLIMATE CHANGE AND AIR POLLUTION CAN AGGRAVATE ASTHMA AND ALLERGIES.

Greenhouse gas emissions from fossil fuels not only pollute our air directly; they also drive climate change, which can indirectly affect the quality of our air. In 2015, the continental US experienced its second-warmest year on record, with the average temperature 2.4F above the twentieth century average. Things are heating up!

As the climate has become warmer, weather patterns change, contributing to higher levels of air pollution like ground-level ozone that can “cause premature deaths, hospital visits, lost school days, and acute respiratory symptoms.”

And that’s not all. The report also predicts wildfires will flare up more and more often, releasing more and more particles into the air and raising the threat of respiratory and cardiovascular diseases. Plus, warming temperatures and rising levels of carbon pollution are expected to lead to higher levels of the allergens that contribute to asthma and other illnesses.

3. CLIMATE CHANGE CAN HELP SPREAD A WHOLE HOST OF VECTOR-BORNE DISEASES.

So, what’s a vector-borne disease? Vector-borne diseases are illnesses spread by insects or arachnids (the vectors) like mosquitoes, fleas, mites, or ticks. And as our climate changes, it’s likely that so too will how far they travel – and how the diseases they carry spread.

For example, the Climate and Health Assessment found that “rising temperatures, changing precipitation patterns, and a higher frequency of some extreme weather events associated with climate change will influence the distribution, abundance, and prevalence” of some vectors like the mosquitos that carry the West Nile virus. In plain terms, they’re expected to range further north and have a longer breeding season. That means a higher probability of Americans contracting this and other illnesses.

4. CLIMATE CHANGE WILL CAUSE RISING TEMPERATURES, POTENTIALLY LEADING TO 150,000 DEATHS IN THE US BY 2100.

As temperatures rise with climate change, scientists expect intense heat waves to happen more frequently, leading to more and more premature deaths. As with other types of extreme weather, increasing heat hits children, the elderly, and low-income communities the hardest through related illnesses including cardiovascular and respiratory diseases as well as diabetes and mental-health issues.

The White House notes that “even small differences from seasonal average temperatures result in illness and death.  An increased risk for respiratory and cardiovascular death is observed in older adults during temperature extremes.”

THE BOTTOM LINE? HEALTHY PEOPLE NEED A HEALTHY PLANET.

EPA Administrator Gina McCarthy said it best: “This isn’t just about glaciers and polar bears. It’s about the health of our family and our kids. To protect ourselves and future generations, we need to understand the health impacts of climate change that are already happening, and those that we expect to see down the road.”
