Introduction
One challenge facing the world today is how to handle issues of global warming and climatic changes; human activities have been blamed as one of the major causes of climatic change and depletion of the environment. Experts have continued debates on the role that human beings play in climatic changes. This paper summarizes the data and the evidence for climate change, including the major conclusions of the 2007 IPCC report.
Greenhouse gases
These are gases are produced by different processes that men engage in as well as those that occurs as natural; they include gases like carbon dioxide, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), methane, nitrous oxide, and sulfur hexafluoride (SF6) ozone; these gases have an effect on ozone layer reducing the sanity of the environment. When human beings are involved in domestic and industrial works, they emit such gases thus causing the greenhouse gases effect (Gaston and Spicer 12).
oceans
The climate changes have increased the acidity of ocean waters; when the acid has increased, then the aquatic life is threatened. Carbon and other gases that increase in the atmosphere because of emissions are the main causes of the acidification of water. When greenhouses reduce the protection of the ozone layer, ice and snow caps on mountain tops melt; when they melt they add to the waters found in oceans and other water bodies. When the volume of water is increased, the result is the oceans reclaiming human settlement land. When the temperatures of oceans increase, it builds a good breeding ground for pests that cause danger to human beings, animals, and plants.
melting sea ice, melting land ice
When the temperatures of the earth increase from global warming, sea ice, and land ice melt; when these ices melt they have an effect on human life as the waters from their melting affect normal human life. They, for instance, add into rivers, lakes, seas, and oceans a reason that leads to displacement of people and sometimes washing them downstream (Cravens 34).
Summarize the possible effects of climate change
There are different reasons why the world is facing increased climate change, the reasons are either human causes or come from natural occurrences. When it comes to natural effects, it involves those activities that emit some wastes or pollutants into the environment, they include solid deposits, deposits in water bodies, and gases that come from natural occurrences.
Human activities have been largely blamed for climate changes; they involve domestic and industrial activities that human beings engage in in the efforts of satisfying their needs.
From the domestic angle, people use fuels and emit gases, solid wastes, and liquid wastes; they do this when cooking, cleaning and burning the products they use to make their life comfortable. When these products get to the environment, they have the potential of polluting it and reducing its sanity.
People have been using different levels of technologies to manufacture goods and services; when they are in the process of making the products, they emit solid, liquid, and gaseous wastes that when they get to the environment they pollute. Some factory deposits affect the climate directly while others take time before their effect has been felt (Ernesto 34).
What percent of climatologists agree that human activities have been the leading cause of atmospheric warming?
According to the climatic change 2007 synthesis report, climatologists agree with the fact that human activities lead to atmospheric warming to 97%; they think that major activities undertaken by human beings harm the atmosphere. They look into industrial wastes, emissions, products, and the process and products they use in production. Although some natural factors cause climate changes, research shows that the effect is negligible and in this case, it is not added by human activities, then the environment has ways of restoring its sanity (Jacobs Remake and Oldeman 90).
What are the reasons some people are denying the evidence of our experts?
Some people are denying the observations by experts as they believe that nature has the resources for human use, thus the exploitation of the resources should not account for environmental damage. Those who oppose believe that what lacks is efficiency in resource use but the very nature of production does not lead to pollution.
When people pollute the environment, they should be ethical enough to try their best and restore the dignity of the environment; when this is done people will feed on the environment without destroying it (Chiras 45).
2007 IPCC report observation
According to the 2007 IPCC report, the world is facing the challenge of controlling the rise of global average air and ocean temperatures, the increased temperatures are resulting in atmospheric climatic changes. Human activities both domestic and industrial have been blamed for the change to a high percentage; however, if governments join efforts and control their economy’s production the trend can be reversed. There should be much emphasis on green technologies adoption in industries and households.
