These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000.
Modernity may cease with global warming as half the biggest companies are oil companies, and oil is the essence of life. Deforestation and the effects of global warming on our forests and trees are far-reaching and quite evident. All our planets physical features are changing rapidly. And McKibben repeats himself on purpose to get his point across: the planet we knew is no more, we live on a new, more complex and harsher
Not just one area but globally! That would give us a better indication of global warming. Artic sea ice is another thing we should be monitoring. “September Arctic sea ice is now declining at a rate of 11.5 percent per decade, relative to the 1979 to 2000 average” (Global Climate Change: Key Indicators, 2014). Due to, again warmer temperatures both maximum and minimum we are seeing ice melt.
Global Warming By Amanda Lardino Sci 275 What are the main causes of global warming? Is there things we can do to prevent it? Those are two of the main questions that have come to mind about the way to focus our thoughts on what can be done to decrease this issue in the world today. One of the major atmospheric issues that has been destroying the environment for years is global warming. I have read that in the present compared to the past global warming has increased tremendously.
Despite that, Subsidence in Venice is caused by both natural and manmade factors. The last IPCC report forecasts a rise of up to 59 cm in sea level rise by the end of this century, due to thermal expansion and melting glaciers. Thermal expansion technically, when water heats up, it expands. Approximately half of the past century's rise in seal level is attributable to warmer oceans merely occupying more
Veronica Torres Mr. Bontrager October 26th, 2012 The Great Climate Flip-Flop= In todays society people do not know what global warming really is. People think all over the world that global warming is worse than it is, or not really important. According to www.merriam-webster.com, “Global Warming 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, chlorofluorocarbons and other pollutants. ” Through many years of research, it has been proven that this has been around for many years and it has been effecting us in a lot of different ways. William H. Calvin, PH.D, has published a book about his studies and his research that he has observed in the past years.
If ongoing pollution cannot be reduced, then the climate is just going to keep getting worse day by day. As a result, not only will a single nation be suffering, but also the entire planet will change due to global warming. Of course, if people can make efficient adaptation plans to control the ongoing global warming and climate change, in the future it can prevent the threat of global warming and many other climate change issues. After all, the consciousness that man could alter the climate of Earth has dawned slowly on their awareness. Work Cited Begley, Sharon.

He gives examples of how the Earth’s climate has changed in many ways over all the years. “During the medieval warming of thousand years ago, temperatures were much higher than they are now; during the Little Ice Age six centuries later they were much lower” (Jacoby 9). Basically he is saying that we have always had climate change, but humans still exist today. Jacoby talks about how they always make predictions about the end of the world, and it never happens. These are some of the reasons why Jacoby thinks that global warming is all just an exaggeration.
We will be talking about parts per million (ppm). 1% = 1 x 10-2 = 10,000 ppm Pre-anthropogenic (1850 AD) concentration means CO2 levels in the atmosphere before humans started to burn coal, peat, oil, and gas in vast quantities. In 1850, the concentration of CO2 in the atmosphere was 280 ppm. CO2 is increasing in the atmosphere at the rate of approximately 2 ppm/yr due to human interaction. In 2013 AD, CO2 in the atmosphere is 396 ppm.
