“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.” - Barack Obama. Global warming is a major problem in the world today and something needs to be done about it before it is to late. We have more than enough evidence from temperature change and sea level change to prove that climate change is happening. The causes and impact have also been discovered recently and are widely known. There is evidence from temperature change and the change in sea level to assure anyone that global warming is occurring. Sea level has rose 17 centimeters in the last century but especially in the last decade where the rate is double that of the last century (Climate change: How do we know?). Oceans have also absorbed much of the increased heat, with the top 700 meters showing warming of 0.302 degrees fahrenheit since 1969 (Climate change: How do we know?). The average annual temperatures since 1970 have been increased by 2 degrees fahrenheit (Climate impacts in the southeast). The polar regions of the earth have had an increase of 1.3 degrees fahrenheit from the the 11-year cycle of solar radiation (Global warming - Just facts). The number of record high temperature events have also been increasing while record low temperature events have been decreasing (Climate change: How do we know?). Carbon dioxide is one of the main causes of global warming. This is because of its heat trapping abilities (Global Warming).

“All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster.” BARACK OBAMA, speech, Apr. 3, 2006. Climate change is not a theory contrary to what many individuals believe and is in fact confirmed by major scientific agencies such as the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA) in the United States. Global Warming causes are mainly due to greenhouse gases that are trapped in the atmosphere and cause depletion of the earth’s ozone layer. Carbon Dioxide is a greenhouse gas, and although it is a necessary component in our atmosphere as it helps plants perform photosynthesis, too much of it causes ozone depletion and therefore climate change. Carbon Dioxide levels in the atmosphere have increased tremendously after the industrial revolution, which indicates that the major cause of this issue is due to anthropogenic activities.
However, climate change is happening. The global average land and sea temperature has increased over the twentieth century, with the North and South Poles being particularly affected (Learmonth, et al., 2006). In turn, this has caused ice cover to decrease and sea levels
Global temperatures have noticeably been rising since the mid 1800’s.The average temperature has increased by 0.6 ± 0.2°C since 1860 according to (John Sweeney, 2003)with accelerated warming apparent in the latter decades of the 20th century. The legitimacy of global warming had long been debated, however in a report by (IPCC, 2007) it states that warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. Simulations on models such as EC-Earth provide us with predictions for future climate change. Depending on levels of emissions an increase of 1 to 5.5 degrees celsius is expected in average global temperatures by 2100.
The major effect most scientists fear as the result of increased levels of CO2 in our atmosphere is global warming. By blocking the heat reflected from the Earth's surface, greenhouse gases are able to warm the planet in a similar way to how glass warms up a greenhouse. Without this greenhouse effect, it is calculated our planet would be 35 degrees Celsius cooler worldwide, causing oceans to freeze and greatly altering life (Doyle, 1996). Accordi...
Over the last few years almost everyone has heard that the earth is warming. Also, almost everyone has heard the pleas to go green and reduce carbon emissions, led by former Vice-President Al Gore. Even though there is not a truly accurate definition of global warming it can be roughly defined as a rise in average global temperature according to Laurence Pringle’s book Global Warming Assessing the Greenhouse Threat (19). Global Warming Assessing the Greenhouse Threat also bring up that the average temperature data that scientist are using only goes back to 1860 giving scientists today only 150 years of temperature data. Also, with this current warming, even with humans contributing to the rising average global temperature, scientist today do not fully understand all the complexities of the atmosphere (Pringle 19-21). According to another book by Mr. Pringle, Global Warming the Threat of Earth’s Changing Climate, scientists predict global temperatures could rise from two to six degrees Celsius by 2050 (33). Despite these predictions historical and new information show that scientist are incorrect that global temperatures will forever continue to increase. Global warming and the rise in global temperatures is due to humans burning fossil fuels and overconsumption of products, as well as natural cycles changing slightly and other natural phenomenon; however, this warming will eventually lead to global cooling.
Global warming has increased the average temperature of the world, because of this; glaciers are melting, oceans are warming and becoming more acidic, the sea level will increase too this is because ice caps are melting and the sea absorbs heat, neither more nor less this will have a negative effect on climate change. Climate changes across space and time, so climate takes a long time to be explored and to discover. The normal preference of climate change depends on different climate scientists. Before thermometers were invented, to understand how climate varies across time, scientists used three kinds of equipment to find the climate data. The types of equipments were observations, historical accounts, and environmental evidence locked up in fossils and ice cores. There are slight differences in global records between different climate groups that are calculating and recording data because they all have a slightly different formula or using different techniques. Each group calculates global temperature year by year. Between 1961 and 1990, the average temperature for the globe was around 57.2°F (14.0°C), according to the ...
Global climate change is a phenomenon widely accepted by the public in today’s society. A survey from Yale revealed that 63% of Americans believe that global warming is currently happening (Leiserowitz, 2013). And although the public has shown to misunderstand the scientific field, in the case of climate change, science supports their beliefs. Now, a majority of scientists accept that extreme changes are occurring in the world. Evidence is showing that worldwide climate change is real, and the consequences will cause adverse effects to all forms of life.

Although it is often a topic for contention in politics, global warming over the span of several decades, has led to climate change, which has had an alarming impact globally. Climate change needs to ...
Two issues that worry many scientists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if there was no greenhouse effect, the earth would be too cold for humans to comfortably exist.
“Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.” - Bill Nye. We are no strangers to the term “climate change” as it is an issue that will come up on every major news outlet or any important website. This single issue generates controversy between the public. Some believe its a hoax, while some offer hard evidence.
Climate change has been an extremely controversial topic in recent history and continues to create much debate today. Many questions concerning climate change’s origins and its potential affect on the globe are not fully understood and remain unanswered. What is climate change? Is climate change happening? Is it a natural cycle of the world or are there other catalysts involved such as human activity? What proof is there? What data correlations show climate change is accelerated by humans? How serious is climate change and how will it affect the future of our globe? What are we doing to address climate change? Should we really be concerned about climate change? Questions such as these have made climate change a very serious issue in today’s world and created the ideology of climatism. The issue of climate change has affected many different aspects of our lives and the world we live in. Policymaking, human activism, technologies, emission control, global warming, alternative energy sources and many other things have been greatly affected by the mania of climate change. This research report will present climate change in a light of common sense and rationality that will take a grounded discussion of the science behind climate change, global warming, human activity, and how the ideology of climatism has corrupted and driven the actions to combat climate change.
Background and Audience Relevance: There are always conversations about our planet. We see our earths glaciers melting, weather temperature rising, and pollution affecting our resources. But for some reasons we tend to look away. We should be more aware of this potential event and I’m here to inform everyone about what actually is global warming and the effects of it.
These changes are becoming more prevalent in our world today, in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2, “The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed.
One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
