IMPLICATIONS OF CLIMATE CHANGE
Increasing systematic affirmation demonstrates that climate change is a glaring threat
both to human beings and to the comprehensive ecosystem. While there may be some
advantages, a significant number of researches propose that effects including progressively
severe weather occurrences, rising sea levels, flooding and droughts will endanger human
health and life.1 Whereas developing nations may be more pregnable to climate change, a lot
of extreme consequences are probably going to be endured in other parts of the globe as well.
Additionally, the danger of climate change cannot be considered exclusively as a future risk
since current biological, as well as climatic inclinations, demonstrate climate change resulting
from human activities is already endangering both human and non-human life.2 In various
parts of the world, for instance, both temperatures and intervals of heavy rainfall occurring
daily as well as drought and desertification have been escalating over the previous century,
with current occurrences striking many regions that have never been affected by such
Climate change culminates in several negative impacts on the human population. One
such impact is the displacement of these populations. Some of the most vulnerable areas
include low-lying regions located proximal to principal rivers, deltas and estuaries which are
exposed to the dangers of the sea level rise; for instance, in Bangladesh, Vietnam and India
and this presents a danger to the sustainability of those communities.3 Historical evidence

shows that drought, as well as desertification, have been significant causes of population
migration in various countries such as Ethiopia, Brazil and Iran.4
Causes of Climate Change
The concentration of carbon dioxide, as well as other greenhouse gasses in the
atmosphere, is unquestionably one of the most common motives that scientific study cites as
the reason for global climate change. The instance sunlight hits the surface of the earth; it is
either reflected into the atmosphere or absorbed by the earth. When the sunlight is absorbed,
the earth discharges part of the energy back into the atmosphere as heat in a process referred
to as infrared radiation. When this happens, greenhouse gases such as carbon
dioxide, methane and water vapour take up this energy, and in the process, they end up
regulating or inhibiting the loss of heat into the atmosphere.5 In this manner, greenhouse
gases act like a blanket over the earth making it warmer than it would be on regular
occasions. The process is typically the “greenhouse effect.”
Other than the greenhouse effect, the natural changes that determine the amount of
solar energy that makes its way onto the earth’s surface also affect the climate. These changes
include alterations within the sun as well as those in Earth’s orbit. Alterations taking place
within the sun, in particular, have the possibility of influencing the strength of the sun’s rays
that hit the surface of the earth. The strength of these rays can either result in warming or
cooling of the earth. Variations in the formation of Earth’s orbit including the angle and
location of Earth’s axis also has the potential to influence the quantity of sunlight making its
way to the earth’s surface.

Human activity on the earth’s surface has also for a long time been considered a
significant contributor to climate change. It mainly results from the activities that humans
engage in economically. Humans progressively contribute to the carbon footprint through
various activities such as industrialisation and transportation which contribute to the level of
carbon dioxide released into the atmosphere. Humans also take part in harmful activities
including the harvesting of natural resources such as forests which result in processes such as
deforestation which ultimately lead to climate change.
The topic of migration as a result of climate has been covered extensively in various
academic publications. World Health Organization (2009) explores the nexus between
climate change, migration as well as adaptation. In their research, however, it becomes
evident that climate change is not a significant determinant of migration and other reasons
such as age and income have a more significant role despite the area being one of those that
are potentially adversely affected by climate change. However, according to the World
Migration Report 2018 by the UN, the present-day increased acceptance that migration
resultant from the climate and environment profoundly establishes itself as one of the
significant challenges of the 21st century.6 Therefore, it calls for proper attention if human
security, as well as sustainable development, continue to be attainable priorities.
In terms of the linkage between climate change and water-borne diseases, Hancock
(2017) reveals the fact that enhanced precipitation as a result of climate change will elevate
the chances of flooding many regions across the globe. Floods are associated with the
increase of human subjection to infectious micro-organisms since floodwaters circulate

contaminants. Floods also destroy water treatment amenities resulting in the distribution of
untreated wastewater to the human population.
Apart from the spread of waterborne diseases, climate change also plays a critical role
in the transmission of malaria. Mainly, it is a consequence of the rise in temperatures, which
creates a conducive breeding environment for mosquitoes. The WHO (2018) reports that
