GLOBAL WARMING
According to Shaftel, “Global warming refers to the upward temperature trend across the
entire Earth since the early 20th century, and most notably since the late 1970s, due to the
increase in fossil fuel emissions since the industrial revolution. Worldwide since 1880, the
average surface temperature has gone up by about 0.8 °C (1.4 °F), relative to the mid-20th-
century baseline (of 1951-1980)”. One of the majorly debated topics about the earth and on earth
is climate change issue. Some of the significant results of the changing nature of climate are
melting glaciers, high rise of sea levels, deaths of cloud forest and scrambling of wildlife to keep
pace. It is not a sceptic but assured that the humans have apparently caused the warming by
various methods. Scientist term the phenomena of climate change as Global warming. The
widespread increase in temperature of the earth’s surface in land, water and atmosphere is
perceived as global warming. Earth’s average temperature has raised by 0.75°C over the last 100
years (Moore). Earlier the causes for the rise in the temperature were the natural causes,
However, today the sole cause of global warming and the changed climate condition is the
addition of toxic greenhouse gases in the atmosphere produced by the human. The purpose of
this essay is to focus on the issue of Global warming as well as the way it impacts on earth along
with recommendations that would contribute to reducing global warming.

Desertification: The process by which human and natural causes deduct the biological
productivity of dryland is called the desertification. Due to several human actions such as climate
change, deforestation, unsustainable irrigation practices, overgrazing and many more, there is a
decline in the productivity of trees (Dai). However, the concept of desertification does not refer
to the physical expansion of the deserts existing from before. Moreover, the different processes
that are counted as threats for all the dryland ecosystems including deserts, grasslands and
scrublands. Research has found that desertification has affected 36 million square km of land and
at present, it is a primary international concern. Also, there are 100 to 200 million people on
earth who have been affected by the desertification, and about 50 million people were affected
by 2017 (Jeppesen et al). The most affected area by desertification is the continent Africa and the
southern edge of the Sahara desert. Desertification is one of the severe environmental challenges
that have a long-term impact such as drought and arid deserts. The extended drought can result in
a rapid reduction of biological productivity of ecosystem, and the change can last for many years
(Berg, et al). The solution for fighting against the desertification is the primary concern of the
environmental scientists. To solve the problem of deforestation, only long-term goals would be
necessary since the issue has extended to the point where the concern is enormous. There would
be an absolute necessity of efficient economic policies and technical measures that for
diminishing the production of green gases. At the micro level, the soil conservation should be
the priority to maintain the biological productivity of the land. Few techniques that would be
helpful to make the soil better are grazing land, rain-fed croplands and irrigated croplands.
Melting of glaciers: The glaciers that are standing tall have taken million of days to form and
they keep melting that forms rivers, lakes and other necessary for human survival across the
globe. The melting ice is again substituted by fresh snow that builds ice over the time and

converts as glaciers (O'Hare, Sweeney & Wilby 122). Ice glaciers either melt or break into the
smaller iceberg that goes to the sea or become rivers and seawater is evaporated continuously
replacing the melting ices (Zhang et al.). Since the primary source of water in the rivers and
lakes is the glaciers, it is a perfectly normal phenomenon. It is an inevitable natural process;
however, the process is dangerous when the melting of snow is more than the snow that is
formed. The excess melting water are not able to evaporate is resulting as excess water body on
earth. The snow replenishing is less in the circle of melting and forming glacier is the matter of
concern and precisely this is another main cause of global warming. The melting glaciers are of
major significance in the environment, they provide water, and they maintain the climate and
humidity level. With all the heat rising in the atmosphere is resulting in melting of glaciers
around the world. The glaciers are reducing in their size failing to form the ice in the same speed
of melting the same ice and raising the sea levels. Due to the global warming, the frosts of the
glaciers are melting faster than required which is resulting in a rise in temperature across the
globe helping in the rise of sea water temperature. It is also to be noted that only 2 percent of the
total water is fresh water that is used by human for primary use (Hansen et al.). The decreasing
glacier mass will lead to severe shortage of freshwater. During the dry season there is an
expectation of shortage of water for agriculture since the rainfall is highly affected by the
melting glaciers. Other expected outcome of the melting glacier is excessive flooding, shortage
of electricity, vanish of coral reef and animal habitat loss. Electricity is formed in the flow of
running water, once the flow of water is lessened the production of electricity will also stop
unless there are no new method of producing electricity ("Biodiversity Of The Great Barrier
Reef"). All the underwater coral reefs that require sunlight for photosynthesis to not be able to
