Climate change presents a clear threat to global security, potentially prompting waves of forced migration that destabilize regions and undermine national sovereignty. Moreover, climate change has a direct and immediate impact on global food supplies, leading to dramatic humanitarian outcomes. The consequences of climate change extend beyond food security concerns and extend into the broader realms of public health, including but not limited to, the spread of communicable diseases. Although most climate change research is based on modeling systems, the lessons learned from current trends in population migration and public health issues can provide some insight into causes and solutions to the problems that climate change presents to both domestic and global security. Gemenne, Barnett, Adger & Dabelko (2014) find that climate change presents “risks of conflict, national security concerns, critical national infrastructure, geo-political rivalries and threats to human security,” (p. 1). Risks of conflict related to climate change include those linked to water or food shortages. Likewise, Wheeler & von Braun (2013) suggest “it is likely that climate variability and change will exacerbate food insecurity in areas currently vulnerable to hunger and undernutrition,” (p. 508). Water security can also become a source of contention between neighboring nations, leading to regional political instability as water-rich nations vie to protect their borders from an influx of migrants or alternatively,...
Therefore, both food and water shortages can exacerbate existing geo-political rivalries, such as those between India and China currently evident in their mutual border regions with Bhutan (Gemenne, Barnett, Adger & Dabelko, 2014). As the critical national infrastructures of nations include consideration for basic human needs like food and water, climate change is easily one of the most pressing global security issues.References

Global Trends and National Security The National Intelligence Council's 2008 report Global Trends 2025: A Transformed World attempts to provide policymakers with a summary of the probable, possible, and plausible changes most likely to affect global governance and stability over the course of the next decade and a half. The report covers a wide range of topics, but perhaps the most salient predictions included in the report, which ultimately serve to
Finally another aspect on which the Security strategy will be focused concerns the idea or promotion of democracy. The United States has always been a front runner in terms of human rights, democracy, and freedom. However, at the moment it is rather difficult to intervene in a country invoking human rights abuses. Indeed, the United Nations is the responsible body for authorizing such interventions. Still, there are other means through
Climate Change Impacts on Agriculture Weather and the related temperature, light and water determine to a large extent the human society's ability to feed themselves and the animals they care for. When the weather changes due to variations n climate or long-terms changes in climate there are very serious impacts on agricultural production and reduction of crop production and these force the farmers to take up new methods of agriculture so
2015, President Obama outlined a set of core national security objectives that included references to ISIL, climate change, and even social justice, all covered in the National Security Strategy. The direction the new administration takes is likely to shift some of the main national security objectives and strategies, while still addressing some of the aforementioned crucial issues. It is a futile attempt to narrow down the range of national
global economy relate to food security and food bank use in Canada. There has been some exploration in the academic literature of the links between the changes in the global economy and food security. There have also been a couple of attempts to examine the linkages between the global issue of food security and the individual issue of food bank usage. This paper will examine this literature to examine
causes of Climate Change? It is ideal to focus on the primary causes of climate change with the aim of understanding the influence or implication on the growth and development of the planet earth. This paper seeks to unveil the major or primary causes in relation to climate change. This is through evaluation of natural and artificial events/activities with massive implication on climate thus changes in the climatic conditions within
