Global Warming

Description

Global warming is one of the most discussed topics on the global level. It has been blamed on recent wild fires in Australia, Greece and California, typhoons in America and Philippines, heat waves in India and famine in Africa. Hotter summers have also been reported in Australia. In total, the death and losses resulting from such calamities are dumfounding. Experts argue that such calamities can be avoided if the people on earth are more conscious of the environment. However, some sceptics argue that the warming of the earth is natural while to some, the earth is getting cooler (Ferrera, 2013). This paper seeks to show that global warming is real

Global warming interferes with the natural balance on earth. Some crops and animals are facing extinction as the environment changes rapidly. The high temperatures also lead to disruption of climatic patterns (UNESCO, 2013). This is so because the air in the atmosphere expands and the water vapour content is higher. The higher evaporation rates courtesy of higher temperatures have led to a drier earth exposing soils to wind erosion and drying up of crops. Water bodies such as rivers and lakes are drying up a faster rate. Climate patterns have changed around the world (Maslin, 2007).

According to NASA, the global average temperatures have increased 1.4 degrees Fahrenheit (0.8 degree Celsius) since 1880 (national geographic news 2007). Much of this increase has happened in recent decades where human activities such as industrialization have polluted the environment. According to the United Nations’ Intergovernmental Panel on Climate Change (IPCC) reports, the 20th century was the warmest in the last 400 years. However, the presence of these gases is important but their over concentration is the problem. Without greenhouse gasses, the earth would be 33o C cooler (Ibid). Therefore, greenhouse gases are important in that they ensure comfortable temperatures on the earth’s surface that can maintain life but excessive amounts of greenhouse gases in the atmosphere are a threat to life itself.

Global warming is caused by higher concentrations of greenhouse gasses in the environment. Industrial processes such as use of coal and petroleum-based fuels release excessive amounts of CO2 into the environment. Other processes such as fracking and gas explorations give out methane, CO2, sulphur dioxide and other harmful gases. Some of the processes that are presumed to be very environmental friendly such as bio gas generation and landfills release large amounts of methane and CO2 into the environment (Maslin, 2007). Deforestation also removes the natural filters of greenhouse gasses. The current laws governing environmental protection are not strict enough. The US and China, the world’s greatest polluters are not signatories to the Kyoto protocol, which commits governments to regulate the amount of harmful emissions from their industries (Pittock, 2009).

A hotter earth has led to melting of the glaciers at the colder north and south poles. The result has been a rise in sea levels leading to some low lying lands adjacent to the oceans to be submerged. Indonesia, Philippines and Netherlands are some of the countries in the world that are most affected (Maslin, 2007). The melting of the glaciers at the pole also interferes with the ecological balance in those particular regions. Global warming has also resulted in unreliable climatic patterns with storms, heat waves, droughts and famine being reported across the world (Radford, 2013). The third world and especially Africa is the most affected with millions facing starvation as a result of failed rains and crops.

Solutions

To curb global warming, the world needs to rethink about industrialization and seek alternative means to fuel growth. Sustainable sources of energy such as wind and solar should be used to replace fossil fuels and coals which are the leading sources of greenhouse gasses. Bio fuels should be used more regularly and their prices kept low to encourage use (UNESCO, 2013).

The government should introduce stricter laws on environmental protection. Deforestation should be strictly regulated and more trees planted. Car manufacturers need to develop more fuel efficient cars that run on renewable energy such as solar and biofuels (UN, 2013). Individuals have the task of buying fuel efficient cars and minimizing their energy foot prints. This involves proper disposal of waste, reducing wastage and burying tasking manufacturers to be more environmental conscious. Individuals can also tackle global warming by planting and protecting trees (Eilperin, 2007).

Stakeholders

All people on earth have a responsibility towards the earth. Individuals, organizations, countries and governments should strive to preserve the environment for future generations. The UN through the IPCC should enact practical laws and policies to guide nations on curbing emissions. Governments should restrict organization and individuals to curb harmful emissions. Organizations have ethical responsibility to maintain a safe environment through minimizing harmful emissions. In short, everyone has a role to play in tackling global warming which is a key preserving life on earth (Eilperin, 2007).

Conclusion

The threat of global warming is real. It has caused enough destruction on earth so far that all should be worried and take active step to tackling the problem. Man is the greatest threat to the earth and it is only him who can reverse the destruction done so far and restore the earth to its natural state. Only then can life go on and be guaranteed for future generations.
