Rising global temperatures could bring an increase in respiratory illnesses, infectious diseases and even depression, according to a new medical journal editorial.
, doctors say climate change poses a 鈥渃ontinuing threat鈥� to public health, akin to the dangers of war and poverty.
鈥淐limate change is happening,鈥� the editorial says. 鈥淭he relationship of heat-waves, floods, and droughts along with adverse outcomes is evident.鈥�
The authors push for a concerted effort to cut back on greenhouse gas emissions, while encouraging health officials to adapt to rising global temperatures.
鈥淐onsensus is substantial that human behaviour contributes to climate change,鈥� the article鈥檚 authors say.
The editorial lists a number of public health issues that could become more common as temperatures rise worldwide. Those risks include:
- Respiratory illnesses caused by severe heat during summer days.
- Increased allergies brought on by more pollen being released into the air during warm seasons.
- A rise in infectious diseases spread by mosquitoes, as the insects carry viruses like West Nile to newly-warmed parts of the world.
- Depression and anxiety in some people, caused by a rise in the number of climate-related natural disasters, including floods and hurricanes.
The editorial is based on numerous health-focused climate change studies, along with weather projections for the next 50 years. Those projections say worldwide temperatures could rise by as much as 2 degrees Celsius by 2050, resulting in more severe heat days around the globe.
The authors say climate change could have wide-ranging and unforeseen consequences beyond those listed in their article. They stress that public awareness is key in cutting back greenhouse gas emissions and fighting climate change.
鈥淓ffective communication may shift knowledge, attitudes and behaviour toward reducing the risks of climate change,鈥� the article says.
