In the millions of years life has been on the planet, a few cataclysmic events have caused huge loss of species. These mass extinctions usually have their origins in giant meteorites crashing into the planet or a temperature drops creates an ice age. In today’s world, it is not global cooling that will cause many species to die but global warming. Now, the only threat from above is that of a missile with a nuclear warhead attached. If nuclear war does not destroy the planet, numerous conventional wars will soon bankrupt it. If this money were diverted to better uses, perhaps the most dangerous situation facing the planet, economic imbalance, could be righted. Every single one of these problems is of such tremendous scope, that it appears impossible to even make a dent in any of them. Despite this, every one of these problems is a moral imperative. Each one must be addressed with our most earnest effort, or it could spell the end of humanity. Global started as a small statistical blip. The global temperature showed minute increases. Even scientist disagreed back then whether or not it was reason for worry. Now these small abnormalities have turned into an extremely strong, upward trend in the global temperature. There is no longer any disagreement among scientists. Global warming is now only debated on the political field where facts give way to errant opinions. While politicians argue over whether capping carbon emissions will harm business, the toll on the Earth is beginning to mount. It is now not whether the icecap will be gone, but when the icecap. In many areas, the heat leads to huge amounts of rainfall causing flooding and mudslides. While this may cause very visible, drastic shows of nature’s fury, there are parts of the... ... middle of paper ... ... scale of these tasks seems daunting on a level that none of us can fully comprehend, this should not discourage us. This is simply because it is on that massive of a scale. The power of one cannot even be seen on this scale. Only the movement of the masses can make a dent. Instead of attacking the issues head on by taking on heavy industry or chaining yourself to a tree, turning the few into the masses is the greatest thing anyone can do to tackle these issues. Creating a lasting, meaningful change can only come from the entire planet coming together in lock step behind these issues. As impossible as this may seem, the world will eventually find itself cornered. As the planet plunges into peril, the masses must be mobilized in order to force their governments in the right direction. Works Cited Schell, J. "No More Unto the Breach."

Climate change is a global problem because this Earth is home to many, and the artificial sources causing climate changes have been caused by many people over the course of many years. The changes can be seen on a day-to-day level through the rise in average surface temperatures (Figure 3A, Figure 3B). Climate change will change landscapes and increase sea levels due to the melting of ice and changes in water runoff; put wildlife at risk of extinction; increase the risk of drought, wildfires, and floods; lead to increased likelihood of storm damage due to stronger storms and storms occurring in previously not at risk regions; and cause a development in more heat related illness (“Climate Change: Threats and Impacts”). The repercussions of climate change will affect every nation, and major changes will have to be made for everything from farming to fashion. With every way of life at risk and every person and nation making contributions, whether extreme or minute, climate change is undoubtedly a global
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
Global warming is amongst the most frightening environmental issues the modern world faces; it’s adverse effects have become significantly more prevalent since the dawn of the 20th century taking the forms of powerful
Global warming is a problem that is often overlooked by many and is hindered among other problems that require immediate actions. Over the last 136 years the temperature in earth has increased 1.7°¬¬¬F. Although an increase of 1.7°¬¬¬F over 136 years may not seem like a lot but humans are destroying the earth at a faster rate than ever before. Human omissions are roughly equal to 4 Hiroshima atomic bombs exploding across the planet every second leaving future generations of human in jeopardy. With warmer climate comes with catastrophic outcomes like drought, which can destabilize the food sources on earth leaving millions of people hungry. Widespread extinction of most species on earth and the melting of polar ice caps can raise the sea level leaving most of the world’s coastal cities under water. This cannot happen overnight but if humans keep omitting at the current rate the outcome of climate change will become prominent
It is now a well-documented scientific fact that both the 20th and 21st centuries have experienced a general trend in terms of global warming. Scientific research and evidence clearly indicate that the earth’s surface temperatures are gradually increasing. There have been a variety of theories pertaining to the fundamental causes of global warming. However, one of the outstanding beliefs is that human activities are distinctively responsible for global warming. Although this phenomenon is not experienced on all regions around the globe, the average temperatures on the globe have increased by 0.7°C since 1900 (Hansen et al., 2006).
Scientists and environmentalists started talking about global warming and the dangers of climate change long time ago but it is now when the consequences of these effects began to manifest themselves in a clearer and even worrisome manner. The temperatures on Earth are rising, the sea level is rising, the amounts of CO2 and ozone in the atmosphere are increasing, the amount and timing of precipitation is changing. All of these issues show tendency to worsen in the future, though it is hard to predict exactly by how much or at what rate they will unfold. One thing is clear – climate change has an impact on almost every area of our life and it deserves our attention and timely response.
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
Leading to our planets slow demise, global climate change is an important issue that has sparked fascinating research on its causes, as well as its future effects. There has been significant change in weather patterns and climate over the past century. Sea levels are rising, ice caps are shrinking, and extreme unexpected disasters are occurring all over the world at an alarming rate. This means devastating outcomes for the future of planet earth, along with all of earth’s inhabitants. Earth is home to billions of people, as well as countless species. The despondent truth is that humanity is to blame for global climate change.
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.
Earth faces one of the most important and complicated issues ever faced, which is climate change. Climate change is the long-term change in atmospheric temperatures and climate. Although it has been denied and prolonged the issue now, it has created an even bigger problem and it has to solved and fast. The human impact over all the years of existence has changed the Earth’s climate completely. More severe storms are occurring, higher and lower temperatures than normal are reported, and some of the planet’s nonrenewable resources are slowly disappearing.
...empts at doing our part. But what is really needed is change at national and global levels. Only by convincing leaders to create laws that improve our energy policy, and pushing companies to adopt sustainable business practices on a global level, can we see real change. (EDF - Environmental Defense Fund , 2015) We need laws, polices, and infringes…..etc. whatever it takes in order to get our CO2 emissions under control. There are plenty of ways to improve on the current state of global warming like limiting global warming pollution, utilizing renewable energy, drive smarter vehicles, or even drive less. However small the action any change in our normal day to day can still help tremendously especially when done by a large number of people. We have to remember that this is the only planet we have and global warming is a global issue that needs to be taken seriously.
There is no doubt that human activity is having a significant impact on our environment. These environmental impacts include depleting our natural resources, air and water pollution, climate change, destruction of habitats, and loss of biodiversity. Because of these growing concerns, we need to learn how to live sustainably. Living sustainably will allow us to conserve our limited resources more wisely so they will be available for future generations (Withgott & Brennan, 2011, Chapter 1).
Climate change is an inevitable phenomenon that is being experienced globally in various forms such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the forth assessment report of the IPCC project even with immediate implementation of mitigation strategies global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damages in the future. It is estimated that mean global temperature will rise by 1.8 ºC - 4.0 ºC by end of the 21st century (Izaurraade, 2009). A new global climate model predicts that in the coming decade the surface air temperature is likely to exceed existing records (Smith et al., 2007). Growing season temperatures in the tropics and subtropics by end of the 21st century will exceed the most extreme temperature recorded in the history (Battistic and Rosamond, 2009).
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors.

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
