According to Environmental Defense Fund, "Burning fossil fuels such as coal or petroleum sends carbon dioxide, methane and other heat-trapping "greenhouse gasses" into the atmosphere. Gradually temperatures climb" When humans burn coal, oil, and gas to generate electricity or drive our cars, carbon dioxide is released into the atmosphere, where it traps heat. A carbon molecule that comes from fossil and deforestation is "lighter" than combined signal of those from other sources(EDF). As scientist measure the "weight" of carbon in the atmosphere over time, they see a gradually increase in the lighter molecules from fossil fuel and deforestation sources that correspond closely to the known trend in emissions(UCSUSA). Assume it like a thermal blanket around the Earth.
Climate change has been occurring over the decades but it is just getting worse and more greenhouse gases are getting trapped in the atmosphere and trapping heat energy from the sun along with it. If humans are so small and can create a mess so big we can clean it up too because it is evident that humans have caused an increase in chemicals and pollution that has altered the chemical composition of the atmosphere which ultimately causes the climate change we see
As time went on, trees used to help reduce the level of carbon dioxide along with other greenhouses gases got cut down. The numbers of trees and forest began to decrease in order to build homes, factories, and cities. As human life became to advance, we added more pollution into our atmosphere. This began to affected climate change due to the extra amount of heat energy being trap on earth’s surface. The surface of our planet became hotter, it created a breeding ground for droughts, wildfires and massive hurricanes.
Climate Change, everyone has probably heard about it in the news or on the web, but what does it really mean and what causes Climate Change to happen? Earth has always cooled and heated itself by rotating around the sun but, scientist found that earth temperature has risen throughout the years, there are many causes of this change in temperature, and the question is who should we blame for this. In my opinion humans are the primary cause of Climate Change because we have incremented the gases in the earth atmosphere, cut down hectares of trees with little to no reforestation of them and caused many accidents that affect the tree population. The first reason why I believe that humans are the primary cause of climate change is
Many experts attributed the root cause of climate change to human activities that comes with the rapid growth of the global economy including human consumption of different sources of energy, rapid rate of deforestation and bush burning. The negative impacts of climate change on crop production, higher average world temperature, rising sea levels, reduced rainfall, amongst others are largely indisputable in the literature. A high taxes on carbon-intensive fuels like coal could reduce their consumption and hence carbon
Global warming will not be helped much by efforts to reduce carbon dioxide emission into the atmosphere. (Shaviv, Veizer 2003) It is believed that temperature variations in the atmosphere are merely due to cosmic forces due to fluctuations in cosmic ray emissions that account for approximately 75 percent of climate variations worldwide rather than human induce actions. They stressed that while the increased release of carbon dioxide into the atmosphere can do damage it is secondary to the forces that are beyond the control of man. “……a significant reduction of the release of greenhouse gases will not significantly lower the global temperature, since only about a third of the warming over the past century should be attributed to man.” (Shaviv, Veizer 2003) According to (Kuban, 2007-2013) thousands of scientists have maintained that there is no convincing or overwhelming evidence that human activity is or ever will be responsible for any catastrophic disruption of the earth’s climate. As such climate change cooperation can only do so much.
During the Eighties and Nineties, the scientific community was divided about the phenomenon of climate change. While it was clear that the planet was getting warmer and that other changes were happening, like rising sea levels and altered rainfall patterns, and that the massive increase in global use of the so-called “fossil fuels” — coal, oil and gas — was changing the amount of carbon dioxide in the air, some scientists were cautious in accepting that human energy use was actually causing the changes that were being observed. As more research has been done, it has become clearer that changes to the global climate have not just followed the increasing human use of fossil fuels but are being caused by that process. The science has now been refined to the point where there is no legitimate dispute about the human influence on climate. That does not mean that the debate is over.
The climate of the earth is always changing. There was a time when it was much warmer than it is now and there was also a time when it was much cooler than it is now. Geologists claim that the earth is warming up and the Earth’s temperature has been raised by 5 degrees during the past few years. As a result from a poll conducted in 2013, it depicts that 66% of the population
Previously the abundant forests were sufficient to buffer this effect however with the large scale clearing of lands throughout the 1900 's and particularly since 1950 this has diminished. This has also paralleled the rise in C02 emissions from industry and may be the reason that it has merely been overlooked. Scientists have focused, as would be expected, on the finer details at the molecular level of the greenhouse effect of global warming and have missed the 'bigger picture ' effects of the earth being heated by the sun 's infra-red rays with each rotation around it 's axis every 24 hours throughout it 's 12 month orbit around the
Nevertheless, it remains a growing problem with the changing rate that has increased so rapidly within these past fifty years. Every year the climate shift due to the increase of pollution and natural gases that elevate into the atmosphere being released into the ozone layer, ecosystem, and environment. Subsequently, affecting the planet and the communities that we live in. And for the most part, people would agree that there is a certain consequence that will
