Essay: Examining Global Climate Change, Greenhouse Gases, and Warming

This essay explores the multifaceted issue of global climate change, delving into its causes, effects, and potential solutions. It begins by outlining the role of greenhouse gases in trapping heat and the exponential increase in their concentration due to human activities, which leads to global warming. The essay discusses the varying public perceptions of climate change, emphasizing that those most affected, such as rural communities and farmers, are often the most aware of the changes. It then examines proposed geoengineering methods, specifically Carbon-dioxide removal (CDR) and Sunlight reflection methods (SRM), evaluating their potential benefits and drawbacks. The essay also addresses the United Nations' efforts to combat climate change, including the Paris Agreement, and highlights the need for new energy sources to slow down global warming. The essay concludes by emphasizing the significant contributions of the United States and China to greenhouse gas emissions and the importance of international cooperation and policy changes in tackling climate change.

THE EFFECTS OF GLOBAL CLIMATE CHANGE
The Climate change has become most important issues around the globe. Due to human
globalization and exploitation of nature, forests and bio-diversities has accelerated the effects of
greenhouse gases. In the day light, Sun is the main source of energy for earth where most of the
light is radiated back to the space. The greenhouse gases in our atmosphere traps the heat and
emit back to the earth surface. This trapped heat helps in maintaining the average temperate of
Earth at nights. The amount of greenhouse gases in our atmosphere has increased exponentially
in last decade by the pollution generated by the humans. Public perceptions over the global
warming differs country to country. The awareness about the climate change are to those who
have felt the change or they can imagine. They are mainly the poor people, farmers or people
who somehow lives closer to the outer world. Global warming causes harsh weathers that means
hot summers, extreme rains and freezing winters (Parson et al., 2017). The people who live in
rural places or in forests with their own culture. These people can tell the changes happening in
the climate. It is surely clear that the climate change is social and cultural issue too.
Many ideas has been proposed for limiting the carbon emission and greenhouse gases.
The approaches are based on the geoengineering of earth’s upper atmosphere which are the
Carbon-dioxide removal (CDR) and Sunlight reflection methods (SRM) (Lights, 2013). CDR
reduces the CO2 from the atmosphere and stores underground within soil, inside salted dooms or
mixed in building materials. On other hand, SRM utilize some atmospheric dust (sulfur
aerosols) in upper atmosphere or planting large mirrors to reflect most of the sunlight into the
space. Spraying sulfur is inspired from the volcanic eruption of earth where the sulfur aerosols
have been seen reducing the local temperature around the eruption. In 1977, Mikhail Budyko had
suggested to spray almost 200,000 tons of sulfur aerosols into the stratosphere (Caldeira & Bala,

2016). However the sulfur is very harmful for the atmosphere and can impact on the greenhouse
gases. These are the most controversial methods that had been proposed for limiting the carbon
emission and reducing global warming.
For tackling the challenges of climate change and global warming, the United Nation
started focusing on the climate change in 1988. Several protocols and policies has been signed by
many countries from then to now. The Paris Agreement is in force from 4th November 2016,
signed by 197 countries and followed by less. Not all the governments are capable of
establishing laws and regulation successfully. For example, USA has failed to set lower fuel
economy standards for the cars. In present time, instead of binding countries, a new pure source
of energy is required for world. From this the global warming can only be slowed down. The
major contributor in greenhouse gases (air pollution) are the USA and China and eighth other
countries together emits 70% of emission of these gases (Builis, 2014). Going forward in time,
the U.N should focus on the new source of energy for replacement in parallel with the policies to
limit the emission.
