health linked to the climate

Health and Well-being Under Threat

Our health is directly linked to the climate. Rising temperatures create dangerous conditions and exacerbate existing health problems.

  • Extreme Heat: More frequent and intense heatwaves increase the risk of heatstroke and dehydration. They also put significant strain on the cardiovascular system, which is especially dangerous for the elderly and those with pre-existing conditions.

  • Worsening Air Quality: Higher temperatures can increase ground-level ozone (smog), which damages lung tissue and can worsen conditions like asthma and bronchitis. Wildfires, made more common by climate change, also release massive amounts of harmful smoke into the atmosphere. 🔥

  • Spreading Diseases: Warmer climates allow disease-carrying insects like mosquitoes and ticks to expand their habitats. This increases the risk of illnesses such as malaria, dengue fever, West Nile virus, and Lyme disease in new regions. 🦟

The Economic Cost 💰

Climate change hits our wallets hard, from individual household budgets to the global economy.

  • Damage to Property and Infrastructure: More powerful storms, floods, and wildfires destroy homes, businesses, roads, and power grids. The cost of rebuilding is astronomical and often falls on taxpayers and homeowners.

  • Food and Water Scarcity: Droughts, floods, and extreme heat can devastate crops, leading to food shortages and higher prices at the grocery store. Water supplies are also threatened by reduced snowpack and saltwater intrusion into coastal freshwater sources.

  • Rising Insurance Costs: As climate-related disasters become more frequent, insurance companies raise premiums to cover the increased risk, making it more expensive to insure homes and businesses.

Environmental Transformation

The planet's physical and biological systems are being fundamentally altered, with consequences that ripple out to affect everyone.

  • Rising Sea Levels: It's not just a future problem. As ocean water warms and expands, and as glaciers and ice sheets melt, sea levels rise. This leads to chronic coastal flooding, erosion, and the loss of valuable coastal land and property.

  • More Extreme Weather: Global warming supercharges the water cycle, leading to more extreme weather events. This means more intense hurricanes, heavier rainfall and flooding in some areas, and longer, more severe droughts in others.

  • Ocean Acidification: The ocean absorbs about a quarter of the carbon dioxide (CO2​) we release. This makes the water more acidic, harming marine life, especially organisms with calcium carbonate shells like corals, clams, and oysters. This process is destroying coral reefs, which are vital ecosystems that support countless marine species and coastal economies.

  • Loss of Biodiversity: As habitats are altered or destroyed by changing climate patterns, many plant and animal species are struggling to adapt or relocate. This disruption leads to a loss of biodiversity, threatening the stability of ecosystems that provide us with clean air, water, and food. The polar bear is a symbol, but the problem affects countless species on every continent.

Aircraft noise environmental justice issue

 Aircraft noise is also an environmental justice issue, as it disproportionately impacts children, seniors, racial minorities, and the poor.  Southern Maryland, Fair Skies Coalition, was founded to seek solutions to decrease aircraft noise and air pollution south of DCA. The most severely impacted neighborhoods are Accokeek (CDP), Bryans Road (CDP), Bennsville (CDP), and Fort Washington (CDP), Maryland.

Attend the July Reagan National Community Working Group meeting. The FAA will discuss the health effects of noise on the human body.

  The Southern Maryland Fair Skies Coalition was founded to seek solutions to decrease aircraft noise and air pollution south of DCA. The most severely impacted neighborhoods are Accokeek (CDP), Bryans Road (CDP), Bennsville (CDP), and Fort Washington (CDP), Maryland. Most of us can hear noise from low-flying aircraft. We may think the noise is only a nuisance. “Noise is defined as “unwanted sound.” Aircraft noise is one, if not the most detrimental environmental effect of aviation. It can cause community annoyance, disrupt sleep, adversely affect children's academic performance, and increase cardiovascular disease risk in people in the vicinity of airports.” - National Institute of Health (NIH) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5437751/ You may want to attend the July Reagan National Community Working Group meeting.

South Side Project

 Southside Express Lanes (South Side project) Virginia VDOT wants to add two new high-occupancy toll (HOT) lanes in each direction along an 11-mile stretch of I-495 between I-395 in Fairfax County and Maryland Route 210 in Prince George’s County, crossing the Woodrow Wilson Bridge – Greater greater Washington, Spending money to go nowhere: Southside Express Lanes should be a Metro extension,  David Edmondson (Contributor) August 20, 2025  I am against the "Southside Project," I live in Accokeek, Maryland. My home is 17 miles south on Indian Head Highway (210). I have lived in Accokeek, Maryland, since 2003. I am now retired. Before I retired, I worked in Fairfax Virginia, and commuted from Accokeek to Fairfax five days a week. I have spent a lot of time on Indian Head Highway and the beltway trying to get to work. I have come to know the traffic patterns well.  “You don’t have to be a weatherman to know which way the wind is blowing.” I don’t have to be a traffic exp...

I wonder if this legislation will help us to get some needed airport noise relief from DCA?

We need to get the  attention of politicians and the FAA to reduce noise in Accokeek from Reagan National airport I wonder if this legislation will help us to get some needed airport noise relief from DCA? Press release by both U.S. Senators Chris Van Hollen and Ben Cardin (Both D-Md.) https://www.vanhollen.senate.gov/news/press-releases/van-hollen-cardin-say-faa-reauthorization-will-boost-maryland-airports-and-protect-passengers All of the politician seems to be concerned about the noise from DCA in Montgomery county and not very much concerned about the noise in Prince George’s County. The people in Montgomery County are highly organized and make the politician aware of their plight.   Check out this Web site for Montgomery County   https://sites.google.com/site/208xxquietskies/home Prince George’s County need to make the FAA and politicians to pay attention to our plight.

Against Beltway Expansion

[PGSC Climate Action] Join Me in Speaking Out Against the Beltway Expansion Our community's health and future are on the line. On October 15th, the Transportation Planning Board will vote on the "Southside Project," a massive beltway expansion that would increase air pollution and traffic in our neighborhoods. I shared in my testimony, this isn't just about traffic, it's personal. I was diagnosed with environmentally triggered asthma at the age of 37, a condition worsened by vehicle pollution. This expansion would fill our air with more harmful pollutants like PM2.5 and ozone, which are known to aggravate respiratory conditions and pose a risk to all of us. But our voices can make a difference. The board needs to hear how this project will impact real people. Will you join me in writing a letter? Share your own story, whether it's concerns about your family's health, the dangerous traffic on roads like MD-210, or the need for better transit options instead...
