Global warming is already having significant and harmful effects on communities, health, and climate. Sea level rise is accelerating. The number of large wildfires is growing. Dangerous heat waves are becoming more common. Extreme storm events are increasing in many areas. More severe droughts are occurring in others. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced
Climate change will have an impact on global temperature. Greenhouse gases, emitted by power plants, automobiles, and fossil fuels, are keeping more heat in the Earth's atmosphere. This heat trapping is causing average temperatures to rise all over the world. “During the 20th century, the Earth’s average temperature rose 1°F to its highest level in the past four centuries this is believed to be the fastest rise in a thousand years” (NASA Global Climate Change, 2014). This increase in temperature is projected to rise year by year. “As temperatures rise globally, droughts will become frequent and more severe. It also raises potential harmful effects for farming, contaminated water supply, and future health conditions” (nature, 2014). Hot temperatures and dry conditions also increase the chances of forest fires.
DOES CLIMATE CHANGE AFFECT WATER RESOURCES?
Water. Water is the basis for life on earth. It hydrates our agricultural resources, powers our hydroelectric power stations and is essential for human hydration, sanitation, and all around survival.
Climate change is a big issue in our day and age, although there are some people who are not don’t seem to fully grasp the idea of climate changer, while other just don't believe that climate change is actually real. Climate change has been proven by scientist that its presence is real and severely effecting our planet with both short term and long term affects. The most obvious sign of climate change is seen in the melting of the glaciers, the changing water and atmospheric temperatures. It is also proven that it is us humans that are the most greatly responsible for global warming, in the past 150 years climate change has been increasing substantially. We are slowly starting to see the effects global warming is having, rising sea levels, temperature warming, prolonged droughts, increase amount of forest fires, pest infestations, increasing breathing problems, and extreme whether conditions. All this caused by certain of our action, such as, greenhouse gas emissions, and fuel consumption.
In recent years, global warming is a topic that has received much attention. It’s is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants, which also known as the green house effect. Global warming can negatively affect the earth's delicate ecosystems. It has been linked to dangerous new weather patterns, the extinction of plant and animal species and so many others bad effects.
Currently, because of instability between the amount of carbon in each area that it flows through, earth and the world’s people are suffering through global climate change. This is also known as global warming, and it caused mainly because of excessive amounts of carbon dioxide being emitted into the atmosphere. This affects the earth’s temperature since the carbon dioxide adds to the layer of greenhouse gases that our earth has wrapped around it. Consequently, because this layer of greenhouse gas is getting thicker, it’s causing the earth to be warmer.
Global Warming changing the earth’s climate is already having an effect on the world’s water supply in many ways, and is predicted to be much worse. Global Warming and climate change will influence water temperatures, weather systems and for the amount of water in streams and rivers. A change in the world’s water is a concern for the whole world. Climate change will affect both the quality and the quality of water, algae and bacteria will grown in areas where they are not normally found, and in other areas, salinity of the water will rise. A rise in atmospheric temperature will speed up the pace of the water cycle, it produce more rapid evaporation leading to more intense storms, floods and drought. In some cases, areas can become susceptible to becoming wetter and drier than normal, experiencing increased flooding in the winter and more drought risks in the summer.
Controversial Sciences: Global Climate Change
Climate change has become a very sore subject for many scientists all around the world. There are some people that believe climate change and global warming are just a simple myths for gullible people, that humans have no affect at all on how our environment is changing. On the other hand, it is also told that 97% of papers taking a side on global climate change caused by humans agree that it is happening (Wayne). Many people read the evidence and can clearly see that humans are causing climate change not only to speed up but cause so many things to change in our environment as a result of it.
According to The Lancet and University College London Institute for Global Health Commission (Lancet): climate change is attributable to several health effects including cardiovascular diseases, diarrhea illnesses, vector-borne illnesses such as malaria, injuries obtained in extreme weather events, and malnutrition (2009). Additionally continual climate change is predicted to contribute to increasing disease rates and premature death (Lancet, 2009). Factors that contribute to such climate change include existing levels of heat, food stress, and exposure to disease vectors (Lancet, 2009).
As the world becomes continually warmer, the effect of climate change in the arctic regions becomes more intense. Within the past 50 years, arctic regions in Canada have experienced warming of 2 to 3 degrees Celsius (Fergal & Prowse, 2007). One of the most important areas in the Canadian arctic is the Cryosphere (Appendix A), which is the area consisting of season snow cover, permafrost glaciers, and sea ice (Fergal & Prowse, 2007). This area is significant because it has provided a stabilized surface for building pipelines, as well as provides access to northern communities (Fergal & Prowse, 2007).
