Air conditioning could 'heat up' London

“If the use of air conditioning were to become widespread, the area affected by a significant anthropogenic contribution would increase.”

The effect of an urban heat island cam lead to an increase in mortality rates as people are less able to recover from the hot temperatures they experience during the day as the heat does not decrease significantly at night.

"It can also increase the demand for cooling and upset sleep patterns, while also putting pressure on water supplies and damaging temperature sensitive infrastructure. The increased reliance on electric cooling can also lead to blackouts.

The report said London had to look carefully at measures to limit the use of air conditioning and continue introducing further energy efficiency approaches.
