Small parks cool the big cities

Just a bit of green in the cities will cool the heat and humidity of the summer because the earth warms up. British scientists found that adding 10% of green space could reduce the surface temperature to 3.8 degrees C.

Parks and green spaces can slow the predicted temperature rise by 2080, when summer is expected to be hotter, drier and wetter in winter.

In cities around the world, growing more plants can help people relax more and reduce the costs of running air conditioners as well as saving energy, biologists of Manchester Roland Ennos University to speak.

In sunny days, urban areas such as intersections in US cities may be 12 degrees C higher than in rural areas. However, the team found that adding green patches could minimize this "urban heat island" effect, because plants could capture and retain water more efficiently than bare buildings or other buildings. parking.
