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.
I have read that in the present compared to the past global warming has increased tremendously. The causes and effects of global warming has been the top of discussion in debates not just between scientist but politicians, businesses and common members of the community. Global warming is defined as a measurable increase in temperature of Earth’s
Whether you drive your car to work, turn on your light to illuminate a dark room or just watching television, you are burning using up energy that is being processed at a coal plant. Now that you know the enemy, let me inform you of its damage. Over the years, it’s been recorded that global warming has warmed up the entire planet causing water levels to rise; this may lead to devastating floods in costal cities all across the world. If that isn’t bad enough, we’re causing man made diseases with all the pollutants in the air. One such disease would be asthma, which takes the lives of 250,000 worldwide every year.
Thermal runaway reaction occurs when the heat generated by a reaction goes beyond the heat removal caused by the available cooling capacity. Heat is accumulated leading to a gradual rise in the temperature of the reaction mass; this causes an increase to the rate of reaction and increases the speed of rate of heat generation. [1] Why are thermal runaway reactions dangerous on industrial scale? Thermal runaway reactions are always said to be dangerous on an industrial scale since the reactions go faster in an industry where they tend to reach higher temperatures. As you would already know that exothermic reactions tend to release quite a large amount of heat, so when the reaction mixture gets very warm, a very hot exothermic reaction begins.
It contributes roughly 30% of the world's sum of coal each year. Australia's coal is marketed all over the world, principally for the Asian economy (44% of Australia's coal is exported to Japan.) Without coal our economy would be devastated. The result would be unemployment, electricity price increases, collapse of consumption,economy and related industries etc, resulting in an entirely new way of life. 1b)Coal is a fossil fuel, which means when it is burnt it releases unwanted pollutants which have a negative and harmful impact on our environment.
Supplying a sustainable source of energy for today’s population is already a challenge, however in the future the world’s population is set to hit a peak of 7.8 billion. From the graph you can see that, in the past, the supply of energy has always followed the pattern of increasing population. This was because the world still had large reserves of untapped fossil fuels, allowing for an increase in production. However as these reserves begin to diminish the supply of energy may fall behind the increase in population unless an alternative form of energy is found, capable of filling the large energy gap left behind from fossil fuels. This coupled with an increase in living for the majority of the world, especially RICs such as India where its oil consumption had increased by 40 million tonnes over a 6 year period, makes supplying the world’s energy demands a very difficult task.
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

Carbon dioxide is a heat trapping greenhouse gas. It gets “released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions” (Global Climate Change: Key Indicators, 2014). An increase in carbon dioxide means more heat is trapped thereby raising the Earth’s temperature. Global surface temperature needs to also be monitored. Not just one area but globally!
How Hurricane Katrina effect gas prices Outrageous gasoline prices is something that all American face at the pump in today economy. Many American wonder what is the cause of the high rates at the pump. There are many factors involved in the answer to the question on what causes gasoline prices to increase suddenly. In 2005, Labor Day Weekend gas prices rose dramatically after hurricane Katrina hit the southern coast of the United States. The devastation of hurricane Katrina damaged many of the United States oil refineries, causing a decrease in crude oil supply, which caused a decrease in gasoline supply.
