A solution to cut extreme heat by up to 6 degrees is in our own backyards

The largest temperature reductions were in the hottest suburbs and those further away from the coast. These significant reductions were mostly achieved thanks to backyard trees.

So this benefit that urban trees provide has two key aspects:

  • maximum cooling happens when needed the most – during days of unbearable heat.

  • maximum cooling happens where needed the most – close to us, the people, in the communities where we live.

Our analysis also shows the humble home garden more than pulls its weight when it comes to reducing extreme urban heat and its harmful effects. Although yards and gardens cover only about 20% of urban land, these private spaces provide more than 40% of the tree cover and 30% of grass cover across western Adelaide. This is comparable to what can be found in many other Australian cities and towns.

I've never understood the fascination with paving and concrete.  You can't lie on that stuff!

You are so right,Dave.  Our yard is covered by at least a half by our large spreading canopies of trees. It creates it's own climate, we are starting to get our side fenced area high in shrubbery and a bit of bamboo on one side.  It is a pity we built a large shed on the best aspect of our yard.

People that visit do often comment on the coolness and cool breezes that are here both at the front and back of the house.  One negative thing about it is the number of mosquitoes that love to live in the cool dark undergrowth.  They almost carry you away.  Can your explain why they are here on this earth. They must have some use.
