Climate change, as argued by Haines (1), is a global phenomenon that is happens due to gases
from greenhouses accumulating in the atmosphere. Climate change affects general public
health of the world’s population either directly or indirectly. This post shall be discussing the
various direct effects and indirect ones which affect the change of climate in public health in
areas like Australia and also the whole world in general.
DIRECT EFFECTS
One of the profoundly felt direct effect of change in climate is the waves of the heat. A
Haines (2) recorded that more deaths have been witnessed in Wales and also in England and
they are associated with the increase in waves of heat frequency. He went on to record in his
article that “most of mortality which is excess from the heat waves is mostly related with the
cerebrovascular, respiratory causes, cardiovascular and they mostly concentrate in elderly
people.” The elderly people get the effects easily because they have weak immune system in
the body thus making the effects to enter the body more easily than in other people.
INDIRECT EFFECTS
It is expected that the increasing temperatures will cause a spread of insect disease vectors
such as mosquitoes. This means that diseases like dengue fever will be on the rise globally
and in Australia, Walter (3). Other indirect effects include a rise in the spread of waterborne
diseases due to flash floods, food insecurity caused by the tornados and whirlwinds which
destroy crops on the fields, and risk of food-related diseases caused by the contamination
released on food products from acidic rain. Severe weather also may have mental and stress-
related disorders. Environmental degradation brought about by the severe weather conditions
will also contribute to the public mental health, civil conflict and forced migration, CDC (4).
Air pollution is also part of climate change and has health implications such as asthma and
cardiovascular diseases, CDC (4).
