Is the global Climate Change Caused by Humans?
The degree of the human population contribution to modern global climate change is a highly discussed topic. The facts on human contribution to climate change are quite clear. Human activities mostly consist of emissions and actions that lead to the destruction of some of the core environmental elements such as water bodies and the air. It is indicated that more than half of the global climate change, especially global warming, is caused by humans (Broughton and Weitzel 10). Some of the aspects that lead to climate change include greenhouse gases, plastic and waste disposal, and destruction of natural components.
It is depicted that the current level of greenhouses gases have been on the rise within the past few years (Su and Kidder). Thus, the ability of the atmosphere to trap heat has decreased. Deforestation and the combustion of fossil fuels are the major contributors to climate change, and they pose a massive threat to human and animal life in the future. Greenhouse emissions have led to the greenhouse effect, which leads to climate change. Some of the sources of greenhouse gas emission include the production of electricity, lead emission for transport carriers, and the burning of fossil fuels. Carbon IV Oxide is the primary gas emission that is produced but human activities through locomotives and burning of oil, coal, and gas.
In conclusion, humans are the most significant contributors to global warming, which is the primary aspect that leads to climate change. The climate change signs are clear, and they include increased, the temperature in some parts of the world, rising of the sea level, and changes in the sea levels. The aspects mentioned above indicate that the land is heating up at a rapid rate because of fossil emissions from human activities, and hence changing the overall climate.
