First of all, the cause of current climate change is typical of global warming has been confirmed is mainly due to human activities. Humans have used more energy mainly from raw materials including coal, oil, natural gas, which was released to the atmosphere increasing the gas causing the greenhouse effect of the atmosphere, leading to raise the temperature of the earth.…

Humans commit many acts which contribute to global warming, such as deforestation, the burning of fossil fuels, and the use of CFCs. These acts all heat our planet by either increases carbon dioxide levels, increases carbon dioxide concentrations, or by destroying the ozone layer, which protects us from ultraviolet radiation. So, this global warming is human caused. We must limit release of this destructive carbon dioxide in order to truly help reduce the effects of this…
For the last 2.5 million years, global temperature has shifted between cold glacial periods that last for around 100 000 years, and warmer interglacial periods that last for around 10 000 years. Right now we are in an interglacial period. 20 000 years ago the Earth was cold. Around 15000 years ago it started to warm up, this was the end of the last glacial period. Over the last 10 000 years the climate has been warm with minor fluctuations, however over the last 1000 years the climate has been fairly constant with small fluctuations in annual temperature. Over the last century global temperature has increased rapidly. This is called global warming; there has been a sharp rise in average temperature, 0.7oc between 1900 and 2000. The temperature increase over the last century has been very fast. There is a consensus among scientists that the changes in climate over the last century are a result in human activities (anthropogenic causes), including Al Gore, as shown in the statement which I agree with. I think the majority of global warming is due to humans therefore it is our right to try and find solutions to diminish global warming as much as we can.…
Global warming is defined by Google as “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, CFCs, and other pollutants”. The “greenhouse effect” is essential to life on Earth. If there were no greenhouse gases, the temperature of the air would be about 32°F or 18°C colder than it is now. The earth would pretty much be a frozen wasteland. We need greenhouse gases.…
Climate change is primarily caused by the growing concentration of heat-trapping gases in the atmosphere often referred to as greenhouse gases (CO2)’. We think this lovely weather is good, but we know it is not normal to have these warm temperatures at certain times of the year. There are over 100 lies…
The view that human activities are likely responsible for most of the observed increase in global mean temperature ("global warming") since the mid-20th century is an accurate reflection of current scientific thinking. Human-induced warming of the climate is expected to continue throughout the 21st century and beyond.…
The basic physics of global warming are pretty straightforward. Carbon dioxide reflects energy in the infrared region, rather than letting it pass through, leading to greenhouse effect. The greenhouse effect heats the Earth because greenhouse gases absorb outgoing radiative energy and re-emit some of it back towards earth. This was first discovered by Svante Arrhenius back in 1896. Burning coal and oil releases carbon dioxide (CO2), these two resources are what we use most to live the way we do today. We have direct measurements of CO2 concentrations in the atmosphere going back more than fifty years, and these measurements confirm that concentrations are rising rapidly. Though natural amounts of CO2 have varied from 180 to 300 parts per million (ppm), today 's CO2 levels are around 390 ppm, that 's 30% more than the highest natural levels. Scientists have confirmed with this information that the unnatural levels of CO2 are indeed manmade (How we know human activity is causing warming).…
Anthropogenic Climate Changes are changes in the atmosphere brought on by human activity, and there is evidence of these kinds of changes all over. By studying the size of the polar ice caps we can see that they are shrinking and this may be due to a warmer atmosphere temperature brought on by none other than an anthropogenic climate change. An IPCC report from 2007 showing levels of some of the greenhouse gases also shows that the levels of greenhouse gases in the earth’s atmosphere has skyrocketed since the post-industrial era, this can only be attributed to man-made machines that have come to rise. So how does human activity attribute to the climate rise?…
Temperatures have been fluctuating in the last 100 years and have increased in the last 30. AGW alarmists see this causing the glaciers to melt, the polar bears to die, and see levels to rise. All of this is based on computer models, which keep many of the variables constant and only show an increase in CO2. Variation in sun temperature is not used in the models…
According to the article Global Warming on NASA’s website, published by Holly Riebeek on June 3, 2010, between 1906 and 2005 the Earth’s average surface temperature rose between 1.1 to 1.6 degrees Fahrenheit. This is not the first time the Earth’s climate has changed. The climate has experienced changes since the beginning of time. Small differences that occur in the Earth’s orbit cause a somewhat different temperature. The sun is the main ingredient when it comes to temperature. In the past, the Earth’s orbit has changed, causing a slight change in temperature (Riebeek 1). This is not what the controversy sweeping the world. The problem is the more drastic change recently because of humans. The Earth has a natural heating mechanism called the Greenhouse Effect. The Greenhouse Effect is a necessary part of human existence. However, the problem is humans are increasing these greenhouse gasses by burning fossil fuels, such as oil, and burning down forests, increasing the carbon dioxide level (2). Without all this, humans would face an inevitable downfall.…
After proving that global warming is real the next step to the argument is that global warming is man made. One major green house gas that contributes to global warming is CO2. The earth’s atmosphere is fragile and is based off of a balanced amount of chemical components like nitrogen and carbon dioxide. When this balance is thrown off due to the amount of gases humans are producing it will cause for the atmosphere to become unstable and allow global warming to occur. The…
The issue of global warming has become a hot topic in not only in American, but all over the world. For years, many politicians have evaded the issue of global warming. But now, all of a sudden, the Democratic Party vows to combat global warming. Now that the Democratic Party has majority in both houses on Congress, they have taken an emphasis over environmental issues, mostly involving global warming. On January 30th, 2007, Congress held its first hearing about global warming. What was concluded in that hearing was that global warming is a fact, and that it is caused by humans. Al Gore conveniently released a movie called The Inconvenient truth", a movie that showed Al Gore giving a speech about the facts ' on global warming and its irrefutable ' repercussion. Just this past February, the Intergovernmental Panel on Climate Change released a summary that blamed global warming on CO2 released into the atmosphere by humans. With scientist backing claims that CO2 is causing global warming, the majority of Americans have made the decision that global warming is in fact true. But what Americans are not exposed is the scientist that claim climate change is part of Earth 's cycle, and that it right on schedule.…
The debt over burning fossil fuels and the impact it has caused on climate change as been discussed over years without answer as to say if the gradual warming of the earth is a natural process or if human activity has added to the acceleration of climate change or is the key behind it. Evidence of this is the hockey stick debt as temperature rise rapidly once humans became developed. One thing we do know is that there are many natural events that possibly could accelerate global warming but also many human factors to. Thus making climate change hard to blame on human activities like burning fossil fuels and or nature.…
Over the past half century our world has become more modernized than ever thought possible. We have innovative things to make our lives quicker and more efficient including DVDs, the IPod, and the Internet. This technology has become integrated into our society and even in a way part of our lives. It has also led to increased manufacturing and production and in turn increased the CO2 output by man kind. However, is this increase substantial enough to cause a change in the Earth's climate? Scientists have been debating this for years and have yet to come up with an answer to this question even with overwhelming evidence supporting the idea that humans are not the cause of global warming. There is too much evidence to deny that the Earth's warming is due to a natural change in the Earth's climate not mankind. Past and future fluctuations in the Earth's climate, the sun and the energy it emits, and North and South Pole activities all prove that man made global warming is a myth that has gotten out of hand.…
