"The climate change induced global warming, and in particular the increased frequency and intensity of heat waves, have been linked to health problems. Among them, scientific works have been reporting an increased incidence of neurological diseases, encompassing also neurodegenerative ones, such as Dementia of Alzheimer's type, Parkinson's Disease, and Motor Neuron Diseases.
Although the increase in prevalence of neurodegenerative diseases is well documented by literature reports, the link between global warming and the enhanced prevalence of such diseases remains elusive. This is the main theme of our work, which aims to examine the connection between high temperature exposure and neurodegenerative diseases.
Firstly, we evaluate the influence of high temperatures exposure on the pathophysiology of these disorders. Secondly, we discuss its effects on the thermoregulation, already compromised in affected patients, and its interference with processes of excitotoxicity, oxidative stress and neuroinflammation, all of them related with neurodegeneration.
Finally, we investigate chronic versus acute stressors on body warming, and put forward a possible interpretation of the beneficial or detrimental effects on the brain, which is responsible for the incidence or progression of neurological disorders." These are the words of the researchers who published the study Climate change and neurodegenerative diseases on the Environmental research.
The climate crisis is generated by various factors, but mostly by anthropogenic factors.
The various greenhouse gases play an important role in the climate since through the greenhouse effect they regulate the flow of energy retained in the earth's atmosphere and contribute to keeping the climatic 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. Man is the most recent of the factors affecting the environment and has been so for a relatively short time.
Its influence began with the development of agriculture and the consequent deforestation of the woods to convert them into arable land and pastures, up to today with large greenhouse gas emissions: CO2 from industries and means of transport and methane in farms.
intensive and in rice fields. According to the theory of global warming, or climate warming, man through his greenhouse gas emissions is responsible for much of the warming period that the Earth is going through today. A small minority of scientists, on the other hand, believe that the weight attributed to man on the climate is overestimated, considering the current phase of climatic warming as a natural phase opposite to the natural periods of climatic cooling.
