The Biggest Climate Change Issues Affecting Harlem, New York

April 21, 2023

Since 2021, some of the biggest climate change issues mentioned by Harlem-based WE ACT and others affecting the world are affecting Harlem.

Here are some of those issues around the community:

Sea level rise

Harlem, located in Northern Manhattan, is vulnerable to the impacts of sea level rise caused by climate change.

Rising sea levels can lead to increased flooding and storm surges during extreme weather events, which can damage infrastructure, and property, and disrupt daily life in the community.

Heat waves

Climate change is expected to exacerbate heat waves in urban areas, including Harlem. Heat waves can have serious health impacts, especially for vulnerable populations such as the elderly, children, and people with pre-existing health conditions.


High temperatures can also strain the power grid and increase energy demand for cooling, leading to potential power outages.

Urban heat island effect

Harlem, like other urban areas, is susceptible to the urban heat island effect, where temperatures in cities can be significantly higher than in surrounding rural areas due to the abundance of concrete, asphalt, and lack of green spaces.

This can lead to higher energy consumption for cooling, increased heat-related health risks, and reduced quality of life for residents.

Air pollution

Urban areas, including Harlem, often experience higher levels of air pollution due to increased industrial activity, transportation emissions, and other human activities.

Air pollution can have detrimental effects on human health, including respiratory illnesses, heart diseases, and other health issues.

Infrastructure vulnerabilities

Harlem‘s aging infrastructure, including its buildings, roads, and water and sewage systems, may be vulnerable to the impacts of climate change, such as flooding and extreme weather events. This can result in property damage, disruptions to daily life, and increased costs for repairs and upgrades.

It’s important to note that the impacts of climate change can vary depending on local conditions and vulnerabilities, and efforts are being made to mitigate and adapt to these challenges in Harlem, NY, and other communities across the world.

It’s crucial to prioritize climate resilience and take action to address these issues through community engagement, policy changes, and sustainable practices to reduce greenhouse gas emissions and promote adaptation measures.

It’s always recommended to consult up-to-date information from reputable sources for the latest understanding of climate change impacts in a specific area.

As of my knowledge cutoff date, please refer to recent research and reports for the most accurate and current information on climate change issues in Harlem, NY.

Additionally, local government and community organizations may have resources and initiatives in place to address these challenges.

Stay informed and engaged to contribute to climate action efforts in your community. Together, we can work towards a more sustainable and resilient future.
