Climate Change And Its Impacts Essay

2542 words - 10 pages

Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty first century. Climate, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet is unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential growth. Between the start of the 20th century and its end the world’s population would triple, and the use of fossil-fuel energy by an average person would quadruple, making a twelve-fold increase in the rate of emission of CO2 from fossil fuels.” Modern medicine and improvements in technology has led to the growth of the human population. Due to this, all human beings who are born tend to stay alive into their old age, whereas in the past, a lot of people would not be able to live for long due to diseases. Also fossil fuels such as oil and gas have become the energy source today, facilitating rapid industrialization. As we burn fossil fuels, it releases more carbon dioxide into the atmosphere. The increased level of carbon dioxide in the atmosphere has caused the planet to become warm in just a hundred years and the planet keeps getting warmer exponentially.
Climate has changes in the past but it has been a gradual change over millions of years. The concern is that, recently the climate has shown an almost unique rapid global warming trend in the past few decades. David Suzuki says, “Climate change occurs when long-term weather patterns are altered – for example through human activity. Global warming is a measure of climate change, and is a rise in the average global temperatures.” Climate change is caused by natural factors such as solar variability and human factors such as greenhouse gases and ozone depletion. Evidence of climate change is growing but we are so dependent on the use of fossil fuels in our everyday life such that it is only making the issue worse. The heavy dependence of fossil fuels will continue to increase the carbon dioxide levels in the atmosphere in a few decades. As the planet warms, there will be consequences. This research paper will address the issue that climate change is occurring and its impact on temperature, oceans, ecosystems, fresh water and the human population.
As a human being on this planet the issue of climate change bothers me because the rapid warming in the last few years is mostly due to human-induced activities and we continue to warm the planet at this instant in time. The planet has warmed in the last hundred years and it is also predicted that it will warm further...

However, India merely used the conference to ‘reaffirm its prioritisation of economic development and the responsibility of developed countries to address climate change’ (Lewer 2008).
