There’s more to Summertime than Heat

Posted on July 15, 2020 by Rishya N.

You can’t miss the telltale sign of summertime: that classic spike in heat. We’re all probably feeling a little sweatier than usual, but the heat is more than just uncomfortable. 

That’s because temperature is directly linked to air quality and our health – and climate change aggravates that link. 

The Basics of Air Pollution 

Ozone is what we more commonly refer to as smog. Particle matter (PM) is a combination of incredibly small solids and liquids in the air that can get trapped in our lungs or bloodstream. Both of these pollution sources are directly associated with increased rates of asthma attacks, heart damage, lung cancer, dementia, and even pregnancy risks. 

State of the Air 

The American Lung Association (ALA) recently released their 2020 “State of the Air” report, which details that nearly half of all Americans live in counties with poor air quality. The report also finds that eight of the Commonwealth’s reporting counties demonstrated more unhealthy days of ozone levels compared to last year’s report. These counties are Barnstable, Bristol, Essex, Middlesex, Norfolk, Plymouth, Suffolk, and Worcester. 

One of the Culprits is Climate Change 

Sources that spew greenhouse gasses, like cars and power plants, also spit out PM and ozone. As climate change continues to bring higher daily average temperatures, air pollution like ozone increases. In fact, the three years studied in ALA’s most recent report (2016-2018) comprise three out of the five hottest years in the United States, correlating with both climate change’s warming effects and the report’s findings of increased unhealthy days of ozone levels.  

Differences in Impact 

We all don’t feel climate change’s impacts on air quality the same. Certain vulnerable populations, such as people of color (especially Black Americans) and low socioeconomic status communities, have shown to suffer disproportionately from public health impacts like increased air pollution.  

A recent systematic review makes this link even more clear. The review’s research team examined over 32 million U.S. births and found a direct connection between exposure to extreme levels of heat, air pollution, and pregnancy risks like underweight or stillborn babies. But they also found that Black mothers and babies across the country suffered these risks at a much higher rate than the rest of the population.  

Breathe Easy, We Can Help 

Albeit in different ways, climate change affects every one of us. Coming together to fight the crisis means acting to protect our communities, our neighbors, and our most vulnerable populations. Anyone can make a difference, here’s how: 

  1. The EPA is rolling back environmental regulations that protect us, wildlife, and plants by refusing to hold polluting companies responsible for greenhouse gas emissions and air pollution accountable. Use your voice to oppose these rollbacks and protect the health of our environment. 
  1. Those who suffer a greater burden from climate change and air pollution tend to be marginalized communities, like people of color. Learn more about climate change and racism and why it’s important to act on climate with equity in mind. 
  1. Take a Climate Pledge to reduce your greenhouse gas emissions by yourself or with your friends, family, and community. 
  1. Sign up for our newsletter, Climate Connection, for climate information, action, and community solutions. We’ll send you monthly updates on climate change and how you can make a difference. 

You Asked, We Answered – Climate Change and Cities

Posted on July 8, 2020 by Rishya N.

Last week, Mass Audubon’s Climate Change Program Director, Alexandra Vecchio, took over our Instagram story to answer your questions about climate change and cities for our First Friday Climate Action Ask Me Anything (AMA).

Here Were the Top Three Most Asked Questions:

Boston Youth Climate Strike, September 2019.

Q: Does climate change affect cities differently?

A: Yes, because of what lies inside cities. Cities contain a large number of impervious surfaces, which don’t absorb water. These surfaces increase runoff and flooding during storm events.

Cities also experience much warmer temperatures compared to surrounding rural or suburban areas due to increased absorption and retention of heat. Our urban centers house less flora than their suburban and rural counterparts, which turn heat into moisture to “sweat” and keep their environment cool. Paired with dark asphalt, buildings, and other typical urban features, our cities are retaining and creating heat at a higher rate.

Q: How can we use nature in our cities to fight climate change?

A: In my city, Somerville, I love to see street trees, which provide habitat for local wildlife, shade for our communities, and natural climate mitigation. Trees mitigate climate change by soaking up the most common greenhouse gas, carbon dioxide, like a sponge.

As we see increased temperatures in Massachusetts due to climate change, trees are particularly important to shade our homes and reduce the amount of energy we use to keep cool. Trees also help alleviate the urban heat island effect: when parts of our cities are significantly hotter than neighboring suburbs.

Q: I’ve seen a lot of rain gardens around Boston. Can you tell me about the impact they have?

A: Rain gardens, or bioswales, use vegetation to help absorb storm water during heavy rain events, filter out pollutants, and then allow the water to slowly sink back into the soil. They can also provide habitats for local pollinators and wildlife.

This nature-based climate solution improves water quality and reduces flood risks – protecting our homes and businesses. Green infrastructure like this can be found all throughout Massachusetts.

We Can Help

It’s easy to focus on the risk climate change poses to our urban centers, but we encourage you to look around your own city for the many climate solutions in action. You can get involved in a street tree planting initiative like the City of Boston’s program, help care for a nearby community garden, or serve on a local board to advocate for the increased use of nature-based solutions or green infrastructure in your own neighborhood.

You can also visit one of our urban wildlife sanctuaries to see natural, urban climate solutions in action: Boston Nature Center in Mattapan, Broad Meadow Brook in Worcester, and Oak Knoll in Attleboro.
