Climate change and cardiovascular diseas

Quantitative variation in one or more of these factors can cause global warming or global cooling of the earth's atmosphere and surface. To these natural factors is added the influence of man who through the use of fossil fuels releases large quantities of CO2, methane and other greenhouse gases into the atmosphere, increasing the action of the greenhouse effect and generating climate overheating that increases the global average temperature of the Earth, with consequences such as desertification, rising and souring of the oceans, more frequent extreme atmospheric phenomena.

The extent and consequences of the phenomenon are of such magnitude that the issue is also called the climate crisis. Global warming indicates the change in the earth's climate that has developed since the beginning of the twentieth century and is still ongoing.

The scientific community attributes this change to emissions into the earth's atmosphere of increasing quantities of greenhouse gases and to other factors all attributable to human activity. The study: Climate change and cardiovascular disease: implications for global health, published on the Nature reviews Cardiology, explained: "Climate change is the greatest existential challenge to planetary and human health and is dictated by a shift in the Earth's weather and air conditions owing to anthropogenic activity.

Climate change has resulted not only in extreme temperatures, but also in an increase in the frequency of droughts, wildfires, dust storms, coastal flooding, storm surges and hurricanes, as well as multiple compound and cascading events.

The interactions between climate change and health outcomes are diverse and complex and include several exposure pathways that might promote the development of non-communicable diseases such as cardiovascular disease. A collaborative approach is needed to solve this climate crisis, whereby medical professionals, scientific researchers, public health officials and policymakers should work together to mitigate and limit the consequences of global warming.

In this Review, we aim to provide an overview of the consequences of climate change on cardiova scular health, which result from direct exposure pathways, such as shifts in ambient temperature, air pollution, forest fires, desert (dust and sand) storms and extreme weather events.

We also describe the populations that are most susceptible to the health effects caused by climate change and propose potential mitigation strategies, with an emphasis on collaboration at the scientific, governmental and policy levels."
