We know what might happen if the trend of increasing universal temperatures continues, but nobody can seem to pinpoint the exact reasons as to why this is happening. Is it a natural phenomenon? Are humans causing it?
Or as Charlie Perry, a U.S. Geological Survey scientist, suggests: Variation in the number of sunspots causes climate change and dismissing the widely accepted theory that it is caused by high levels of carbon dioxide (Lawrence Journal World 3). For background, a sunspot is a region on the Sun's photosphere that is cooler and darker than the surrounding material. Sunspots often appear in pairs or groups with specific magnetic polarities that indicate electromagnetic origins. He points to the fact that every eleven years, the sun goes through cycles of high and low sun activity; right now we are at a period of minimal sun activity. In fact, in 2009 the sun was on track to set a record of the least amount of sunspots in a three-year period (1). However there is an inherent problem to his argument: He provides no scientific data as to how sun activity affects the temperature of our climate. The only piece of evidence he could provide was that one of the cycles occurred in 1913, which he says is “a time when old-timers talk about it being really cold” (2). Readers sent in let...

Explaining the Controversy Over the Causes of Global Warming in the Article “Global Climate Change Triggered By Global Warming”
- There has been a great amount of controversy over the actual causation of global warming on behalf of the global climate change. Due to the advancements of technology and greater knowledge on how the Earth operates, climatologists are equipped with the ability to discover analytic data that will build stronger evidence to support their claims. This means that they are able to collect accurate data over weather patterns and find past climatic history. Ample researching has been in action for decades to determine the true factors of global warming.... [tags: fluctuations, greenhouse, factors]

- The causes and effects of Global Warming The Earth has experienced considerable climate change for the last several centuries. There have been many explanations toward the main causes of the increased warming of the planet, but according to IPCC climate report: human impact is unequivocal. The recent weather events that Canada has experienced in Toronto and Calgary have proven Canada is at great risk from the climate change. A UN panel said it was more certain than ever that humans were the cause of global warming and they also predicted temperatures could rise from 0.3 to 4.8 degrees Celsius in this century....

- Global Warming: Cause and Mitigation Climate change can be attributed to both natural and anthropogenic factors. I think that most scientists agree that there are natural causes to climate change. This is proven by the sun, greenhouse effect, and reflectivity. The natural cycle orbital variations of the Sun initiate global warming. This then triggers the release of the greenhouse gases, carbon dioxide, and methane (Hilderman, 2011). These gases intensify the orbital warming. So, the natural climate cycle occurs because of orbital changes and greenhouse gases.... [tags: Global warming, Climate change, Greenhouse gas]

- What are the risks of climate change and global warming. Climate change is changing our economy, health and communities in a lot of different ways. Scientists have warned us that if we do not do something soon to stop polluting our planet, the results will likely be disastrous. Climate change affects all of us. Global warming can increase the chances of illness and some cases death because of the extreme heat and heat waves. Some people still don’t believe that global warming is real, but because of a lot of studies, that scientist have conducted, we have proof that is it real and we need to do something about it....

- Climate change (global warming) is a problematic issue, and this problem is growing. To make matters worse, this problem is a manifestation of human activities. People’s actions are resulting in devastating impacts to the environment. Unfortunately, not everyone concurs to this reasoning. Even with empirical data presented, there are skeptics who attribute climate change to natural causes rather than man-made causes. In order to prevent global warming from exacerbating, it is crucial for people to understand that climate change is happening; it is changing “even more radically,” (Emanuel 6) than ever, and humanity is the cause....

- The climate change term can be explained by dividing it into two words climate and change. The climate is the condition of the weather of earth that lasts for the long time period of time. Climate change is also called as global warming which refers to the rise in average surface temperatures on the earth. Climate is getting effected by the human activities which they possess, and human are only the one who are responsible for the climate change, it is more of emissions of greenhouse gas which are released from old vehicles, industries etc....

- Global Climate Change Have you ever walk outside in the middle of a hot summer and wonder why each year it’s getting hotter or why there is less snow each winter. Have you heard of global warming. Icebergs melting. Sea level rising. Polar bears dying. This is probably not new to anyone. Everyone could have heard of global warming a million times on TV or news. Though, many people do not know or do not have much knowledge on what are the causes of global warming. Greenhouse gases is the cause of global warming which leads to global climate change that affect the environment, sociopolitical, and economic all over the world....

- Most scientists studying climate change believe that humans are to blame for climate change and the extreme weather condition that is happening all across the globe today. These scientist have presented vital scientific evidence that shows that the earth 's climate is warming at an alarming rate. While natural variables continues to play a key role in extreme weather, climate change has shifted the odds and change the natural limits, making heat waves more frequent and more intense today. The earth is warming up faster than we can imagine.... [tags: Global warming, Carbon dioxide, Climate change]

- “Climatism is the belief that man-made greenhouse gases are destroying earth’s climate” said Steve Goreham, the executive director of the Climate Science Coalition of America and author of the book “The Mad, Mad, Mad World of Climatism: Mankind and Climate Change Mania”. Historically, earth climate has become a major problem after the Industrial Revolution during the 18th and 19th century and it significantly becomes a big concern in the present days. This essay will illustrate the possible root of climate change which is caused by mankind as well as nature.... [tags: Global Warming Essays]

- Many people might think that anthropogenic influences are the only cause to climate change on Earth. However, there are many factors which are unnoticed by the human population that contributes to this crucial issue. For example, the most common phenomenon is global warming which is a factor to the progression of climate change over time. (1) This means that climate change has not just happened for a year, but throughout the Earth`s climatic history. In the modern era, this has been a controversial issue at which people only think that human activity is a primary cause of climate change, but there is a consensus view of this problem....
