How Do Trees Help Reduce Temperature?

How can trees reduce temperature? In this post, East Coast Arbor Pro Inc., your experts for tree removal in Palm Bay, FL, explains more about how a tree canopy and green infrastructure help to restore climate resilience. 

What Is an Urban Heat Island? 

As a modern phenomenon, urban heat islands refer to areas in a city with higher-than-normal temperatures. The reason for this stems from our towns consisting of many materials that retain heat. We also drive vehicles and use electricity, which drives up the temperature even more. 

These pockets become worse in bigger cities but can occur in any built-up area, even a large neighborhood. The city can be as much as 22 degrees warmer than the surrounding countryside. We discuss two types of heat islands. 

Surface Heat Islands

Artificial surfaces like roads and roofs absorb heat more than natural surfaces like grass. Concrete and other building materials soak up heat, increasing the daytime temperatures. People use air conditioning to compensate, and this exacerbates the problem. 

Atmospheric Heat Islands

These refer to the effect of the heat on the atmosphere in urban areas. They result from the buildings releasing the heat they absorb during the day. Therefore, they increase the temperature at night rather than throughout the day. 

How Do Trees Help With Temperature Reduction? 

When you understand that trees die due to environmental factors, you may think they’re at the mercy of the climate. The opposite is true when dealing with indigenous trees. Yes, they need the right soil and enough moisture to grow, but they impact the environment more than you realize. 

Let’s look at the cooling effect of trees and how trees reduce temperature. 

Shade

You’ll understand the value of shade if you’ve been outdoors on a hot summer day. The area beneath canopies provides a welcome respite from the sun’s rays. The shade also prevents the ground it covers from absorbing as much solar radiation, making it another great way trees reduce temperature.

Trees in parking lots play havoc with the paving, but they make the experience far more pleasant for shoppers. 

Evapotranspiration

This is a fancy term for the simple process by which moisture transfers from the ground into the atmosphere. Trees facilitate this process by absorbing water deep underground and releasing it from their leaves and trunks when the sun shines. 

This cools the tree and the air around it because the tree draws heat from the atmosphere to transform the water into vapor. 

Using Less Energy

Carefully positioning trees can provide shade and reduce surface temperatures. This effectively regulates temperatures within your home, meaning you don’t need to use fans and air conditioning as much. If the tree shades the water pipes into your home, you also save because you don’t have to run the faucet waiting for cold water. 

Furthermore, you might feel more like spending time outdoors under your beautiful tree and not need to use the HVAC quite as much. That said, you must be careful how close you plant trees to structures, as the roots can crumble foundations, and overhanging branches may damage roofs or windows.
