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 a...

Essay about Impacts of Climate Change - There is widespread agreement in the scientific community that the climate is changing and it has likely received contributions from humans in the form of increased carbon emissions. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change has stated that there is ninety percent certainty that human activity has been the primary cause of temperature rises seen since 1950; if the climate rises by more than two degrees Celsius, scientists predict dire consequences to be faced by humans and the world (McMichael and Lindgren, 2011, p....   [tags: Human Health, Infectous Diseases]

Occurence of Climate Change and Its Impacts on Life Essay - Climate change is already beginning to affect plants, animals and their role in the ecosystem. Ecosystems are very important as provides habitable conditions. Ecosystems are sensitive to the changes placed upon them whether it is natural or human related. According to Fletcher, “Studies shows that natural decreases in biodiversity are as potentially damaging as the negative impacts resulting from climate change, pollution and other major forms of environmental stress. Because natural stressors are ever present, the growth of negative impacts related to climate change and human population growth could cause increasing damage to ecosystems that are already stressed as a natural condition.” Thi...   [tags: ecosystems, plants, animals]

Essay about Impacts of Rainforests on Global Climate Change - Introduction Imagine a rainforest with misty, lush canopies creating a vibrant green carpet over sloping valleys; sunlight dances down along the leaves, branches, and trunks until it is only a rare glow in the dense, dimlit undergrowth. The forest is alive with the heat and humidity, with the cacophony of birds, the chattering of primates and monkeys, and the hum of insects all foraging through the greenery. This is an idealistic rainforest, still unspoiled by man’s industry, the desire for conquest and dominion still held at bay while the living things grow and die in a perpetual cycle of survival....   [tags: human activities, habitat, deforestation]

Impacts of Global Climate Change on Temperature and Precipitation Patterns in the Midwest and the Consequences for Soils - Impacts of Global Climate Change on Temperature and Precipitation Patterns in the Midwest and the Consequences for Soils Introduction During the last century, human activities in agriculture, industry and technology have brought about a change in the chemical composition of the atmosphere. This change so far has not had a noticeable or discernible effect on world climate, but if these same activities continue, global climate change will become irreversible. The major contributing factor is the increase in the amount of carbon dioxide and other gasses in the atmosphere....   [tags: Environment Environmental Essays]

Global Warming and Climate Change Essay - Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”. Rather than worry too much about emissions, we should accept the world is going to get warmer anyway and adapt to global warming by building better flood defenses and developing drought resistant crops....   [tags: Climate Change Essays]
