Climate change correlation with spread of infectious diseases

The various greenhouse gases play an important role in the climate crisis since through the greenhouse effect they regulate the flow of energy retained in the earth's atmosphere and help to keep climate parameters constant by reacting in the phases of climate warming and cooling.

The predicted scenarios postulate that, as the planet warms, the polar ice caps melt and since snow has a high albedo, the decrease in the polar ice caps will result in a further increase in temperatures. Furthermore, the warming of the seas will lead to more evaporation and since water vapor is also a greenhouse gas, it will produce an amplifying effect.

Conversely, an increase in cloud cover due to greater evaporation will contribute to the increase in albedo and therefore, theoretically, to global cooling. The study: Impact of climate change and biodiversity collapse on the global emergence and spread of infectious diseases, published on the Journal of paediatrics and child health, explained: "The reality of climate change and biodiversity collapse is irrefutable in the 21st century, with urgent action required not only to conserve threatened species but also to protect human life and wellbeing.

This existential threat forces us to recognize that our existence is completely dependent upon well-functioning ecosystems that sustain the diversity of life on our planet, including that required for human health. By synthesising data on the ecology, epidemiology and evolutionary biology of various pathogens, we are gaining a better understanding of factors that underlie disease emergence and spread.

However, our knowledge remains rudimentary with limited insight into the complex feedback loops that underlie ecological stability , which are at risk of rapidly unraveling once certain tipping poi nts are breached. In this paper, we consider the impact of climate change and biodiversity collapse on the ever-present risk of infectious disease emergence and spread.

We review historical and contemporaneous infectious diseases that have been influenced by human environmental manipulation, including zoonoses and vector- and water-borne diseases, alongside an evaluation of the impact of migration, urbanization and human density on transmissible diseases.

T he current lack of urgency in political commitment to address climate change warrants enhanced understanding and action from paediatricians - to ensure that we safeguard the health and wellbeing of children in our care today, as well as those of future generations."
