Instructions: This is a template. I have provided a rough idea or a working script of how to write the memo, so you will find the structure of the memo in here. But use your own ideas to write your own memo on your own topic. This is not a :rigid: structure, rather it is just an indication. It is NOT the best memo out there, as a matter of fact, you should be able to write a better memo. You can either use the Word template I shared on the HLTH214 learn site to write the memo, or you can "fork" this article and write your own stuff and share the article with me. DO NOT EDIT this document. If you want to work directly on Authorea, please let me know, and I will show you how to do it.
Body of the memo
Mr A Councilor
My District
Office of the Environment
Subject: The district needs to frame policies on addressing effects of climate change
Our changing climate patterns, brought about by an increase in the temperature of the globe due to accumulation of greenhouse gases, has health consequences for everyone in the world. I'd like to highlight the global and local issues we have faced in our district and would like to indicate some steps we can take to mitigate the effects of climate change we face.
As early as the turn of the last century (c. 1890s), scientists have warned that an increase in the emission of carbon dioxide and accumulation of carbon dioxide in our atmosphere would increase the surface temperature of the earth. In turn, the scientists claimed that this would trigger melting of the glaciers and rising in the sea levels\cite{hulme2009we}. Indeed, since the 1960s, when the post-industrial revolution era and the impact of the climate change was started to be felt, the pace of climate change has been fast and furious and has put the region of Australasia and Southern Pacific at particular risk of environmental disasters. In particular, the rising levels of ocean, altered salinity of the ocean levels, increased temperature, melting of glaciers, loss of biodiversity and coral reefs, increased frequency of storms and cyclones are some of the environmental factors that threaten not only our region and our country, but also the world in particular with different levels of environmental impacts \cite{newman2017tracking} .
As you may know, in 1859, the Irish physicist John Tyndall discovered that carbon dioxide in the atmosphere absorbed the heat and variation in the concentration of carbon dioxide would lead to variation in the gaseous composition of the atmosphere would affect the temperature of the atmosphere (cite). In 1893, the Swedish chemist Svante Arrhenius found that combustion of coal and petroleum was linked with increased temperature of the earth and predicted that increased fossil fuel burning would increase the temperature of earth with consequences \cite{fleming2005historical} . Subsequently, scientists started developing models of what would happen if the global temperature continued to increase. By 1957, it was known that the carbon dioxide concentration of earth's atmosphere continued to increase and that, the global temperature connected to this increase continued to rise. In 1958, Charles Keeling measured the carbon dioxide concentration in the environment at the Mauna Loa earth station off the coast of Hawaii and found a continuous increase in the carbon dioxide concentration \cite{harris2010charles} (Figure 1)
