 * Indirect - "Threats to emotional well-being based on observation of impacts and concern or uncertainty about future risks"

As people become more aware of climate change and continue experiencing its effects, it’s more than likely they may begin to encounter or arouse a post-traumatic stress disorder (PTSD) due to the series of drastic weather events. Oftentimes these disorders will lead to the beginning of new ones such as anxiety, hopelessness,  depression, or suicidal ideation. Additionally, it may also exacerbate ongoing mental health disorders. As people start feeling the weight of climate change like sea level rise, excessive drought periods, rising temperatures, food disruptions, etc, they may suffer from financial damage, community displacement, relationship stress, along with other stressful events in their lives.


 * Direct - "Acute or traumatic effects of extreme weather events and a changed environment"

Climate change has impacted people directly through rising temperatures, sea level rise, and extreme events in the hydrologic cycle that are causing damage. Due to massive floods and strong storms there has been a large quantity of infrastructure damage. This has also had an impact on food security. Additionally, water and air have been drastically polluted due to infrastructure destruction that has chemically impacted those systems. High greenhouse gas concentrations are causing many people lung diseases and other harmful diseases. Ecological disruptions such as plagues, floods, and food shortages come from unfortunate weather conditions that over the years have strongly affected humans.

Extreme weather events: This trend towards more variability and fluctuation is perhaps more important, in terms of its impact on human health, than that of a gradual and long-term trend towards higher average temperature. Infectious disease often accompanies extreme weather events, such as floods, earthquakes and drought. These local epidemics occur due to loss of infrastructure, such as hospitals and sanitation services, but also because of changes in local ecology and environment.

These changing trends in temperatures are having different effects on humans and therefore are creating more long term damages. Rising diseases are one of the consequences stemming from climate change. Warmer temperatures are influencing the instantaneous development of biochemical reactions, leading to the rapid increase in growth and reproduction. The biogeography is a great factor of the variability of disease growth. In the tropics the larger the species diversity, it indicates that at lower altitudes there's a strong energy source. This means that high temperatures can lead to a faster species growth that will last shorter generations based on these climatic changes.

Security:Additionally, researchers studying ancient climate patterns (paleoclimatology) have shown that long-term fluctuations of war frequency and population changes have followed cycles of temperature change since the preindustrial era. A 2016 study finds that "drought can contribute to sustaining conflict, especially for agriculturally dependent groups and politically excluded groups in very poor countries. These results suggest a reciprocal nature–society interaction in which violent conflict and environmental shock constitute a vicious circle, each phenomenon increasing the group’s vulnerability to the other."

Paleoclimatologist's have determined the connections between war frequencies and population changes which have led to the various cycles in temperatures. Securitization is a slow process that builds on an issue resulting from a variety of political actions and choices. Different researchers have done several analyses regarding whether or not climate change has been securitized. It’s essential to understand securitization because it could lead to the placing of certain policies. The disasters leading to this process include the vast disturbances in certain communities that have become unsafe and have made them more vulnerable to economic, human, and environmental losses. Different cases have been able to prove this problem in many communities.
