Recent report by a commission of academics from University College London highlighted various adverse effects of climate change. Authors of the report presented the urgent need to consider threats offered by climate change.

Report's authors said that the NHS would face serious incremental pressures from heat and hygiene-related illnesses because of increasingly hot summers, greater pathogen spread with warmer temperatures, and the heightened risk of flooding.

Professor Anthony Costello, a paediatrician and director of UCL Institute for Global Health, said that he had not realised the full ramifications of climate change on health until 18 months ago.

He declared the threat as a "clear and present danger" that would affect billions of lives.
21st-century public health movement to deal with climate change will be an important step. He added that failure to act will result in future generations feeling the same moral outrage as is felt today towards those "who brought in and did nothing to stop slavery".
