How Urban Park Space Can Offset Rising Temperature
A new study has shown that increasing urban park space can have a significant effect on reducing city temperatures -- a strategy that could be used to mitigate the temperature increase caused by climate change.
"Creating more parks and green spaces in urban areas could cool cities by up to 4°C – possibly enough to offset the warming from climate change – say researchers."
"'We found that the temperature in Manchester will go up by 4°C by 2080 if the amount of green area remains unchanged,' says Roland Ennos of Manchester University in the UK.
"But, by altering the amounts of green cover in the city, the researchers found that the temperature rise could effectively be cancelled out. 'Adding 10% of green cover could reduce surface temperatures by 4°C by 2080,' he said."

Urban Heat Islands.
It is important to remember that the total land fraction occupied by urban areas is small. Reducing the UHI is obviously important, but will do little to reduce the total amount of increase in global or even regional temperatures. Most studies to date have found the total effect of UHIs on global temps to be small.
