Case Study: Climate Change, the 97% Consensus, and Human Impact

This case study examines climate change, focusing on the often-cited figure that 97% of climate experts agree that climate change is human-caused. It explores the causes of climate change, including deforestation and intensive agriculture, and their impact on the environment. The study analyzes the effects of climate change, such as increased violent weather phenomena, and its influence on health, including the estimated increase in deaths and direct damage costs. The study reviews the consensus on human activities as the major driver of climate change, referencing peer-reviewed articles and expert assessments. It also considers the vulnerability of different populations to the effects of climate change, particularly those in developing countries and small island states. The case study also highlights the impact on health, natural disasters, and variable rainfall patterns. The conclusion reinforces the role of human activities as the primary cause of climate change.

MAIN BODY
Climate change
The climatic change is referred to as the changes relating to long term within the patterns
which are used to describe the regional, local and global climate of the earth. These changes have
a wide range of impact over the working of the earth and its activities. The climate changes also
increase the appearance of more violent weather phenomena like droughts, fire, floods and many
other different issues. There are many different causes underline the climate change (El-Sayed
and Kamel, 2020). The major reason for the climatic changes is the deforestation. This is
particularly because of the reason that deforestation is referred to as cutting down of trees and
pictures of this the carbon dioxide is more within the environment, and this can affect the
climate. In addition to this, another major reason for the climatic changes is the increasing
intensive agriculture which emits the greenhouse gases like methane, nitrous oxide and many
others, and this affects the environmental conditions.
With many different peer-reviewed articles, it was evaluated that the climate warming
trends are present over the past century and are extremely affecting the climate and are done
because of human activities. This is particularly because of the reason that the activities of
humans definitely results in harming the environment and their causes use impact over the
climatic conditions within the environment. Most of the people have an opinion that the climatic
changes are major because of the human activities only. The reason underlying this fact is that
humans have increased the use of the fossil fuels like coal oil gas in order to generate electricity
and other purposes. Hence, all this result in meeting of different gases and substances which
affect the overall environment nearby. In addition to this, it is also stated that the major aspects
relating to the climatic changes are the activities of people only. The reason underlying this fact
is that all these different causes negatively affect and impact working and the climatic changes.
In addition to this, with the help of the different articles, it was analysed and viewed that
the climate changes will result in affecting the environmental and social determinants of health to
a great extent. This is particularly because of the reason that all the aspects within the
environment, such as safe drinking water, food and shelter, are affected or affected due to the
climatic changes (Ashraf and et.al., 2019). With the help of research, it was added that between
the time period of 2030 and 2050, it is estimated that I'm the climate changes would cause

approximately 250000 additional deaths per year. These steps may be particularly important
because of the reasons like malnutrition, diarrhoea, malaria, heat stress and many other related
reasons (Ng and Ren 2018). Along with this, the direct damage caused to help is also estimated
to be between the ranges of USD 224 billion per year by 2030. Along with this, it was evaluated
that areas with weak health infrastructure that is majorly in the developing countries would be
the least able to cope with them.
Furthermore, with the evaluation of the climatic changes, it was analysed that over the
last 50 years the human activities have affected the climate to a great extent. All these climatic
changes had a major impact on the health of the person. The reason underlying this part is that
due to the climatic changes many natural disasters and variable rainfall pattern have been
observed, and this has affected the mental health and physical well-being of people to a great
extent. In addition to this sum, all these natural disasters and the rainfall pattern have also caused
your loss to the people. The natural disasters like the flood, droughts, cyclones and many other
have caused serious damage to the properties and living of people to a great extent (The effects
of climate change, 2021). While measuring the health facts from the climatic changes, all the
possible health impacts are being undertaken as a subset. With the help of the WHO assessment,
it was analysed that the change in the climate is estimated to result in around 250000 deaths.
In addition to this, 38000 elderly people are exposed to heat. Whereas 48000 suffer from
diarrhoea and 60000 from malaria along with 95000 due to childhood under nutrition. These all
are the estimations of the WHO, and for improving the position it is very essential that people try
to maintain the climate and their surroundings (Climate change and health, 2021). The reason
underlying this fact is that if the surroundings of the people will be maintained, then this will
definitely result in protection of the climate and will result in effective management. Due to all
these estimated climatic changes, it is evaluated that the people who are mostly at risk are people
living within small islands in developing States or near to the coastal areas. In addition, these
children, particularly those living in the poor countries, are more vulnerable relating to the health
risk and the, manner in which it will be exposed to the long health consequences.
In addition to this, the areas wherein weak health infrastructure is present, especially
within the under developed and developing countries will also find it difficult to cope with the
changes within the climate (Espinoza and et.al., 2019). Furthermore, with the valuation it was
also analysed that the major cause of theme climate changes is regarded as 97% participation of

the human activity. The consensus supports the fact that 97% of the drastic changes within the
climate are caused by human activities.
CONCLUSION
In the end, the above report concluded the fact that the climatic changes are majorly
being undertaken with the help of human activities only. With the above evaluation, it was
analysed that the major causes of climate changes are human activities like deforestation,
increasing intensive agriculture and many other different reasons.
