The progressing debate on the validity of man-made climate change continues to rely on the emergence of new evidence that supports each side. While challengers of the theory of man-made climate change would argue that natural events such as some glaciers around the world actually expanding, advocates of global warming, such as James Balog, contend that man-made climate change is a crucial and ominous progression that will soon lead to the downfall of planet Earth. In fact, Chasing Ice, a documentary that exhibits Balog’s influential experiment, the Extreme Ice Survey (EIS), presents evidence of massive glacial recessions as a direct cause of man-made climate change which is captured with hundreds of thousands of photos and implies the imminent …show more content…
Some of Balog’s time-lapses illustrate how much ice breaks of from the glaciers each day and eventually reaches the oceans which contributes to rising sea levels. In one of Balog’s most extreme feats, he sent some of his scientists out to the Ilulissat Glacier in Greenland to record a mega-chunk of ice over one kilometer wide break off from the glacier. Over the course of a few weeks, they overcame extreme weather conditions without any sign of the massive impending calving event. Their diligence and perseverance eventually paid off, as they managed to record a rare calving event, and the largest one ever recorded. Their discovery exhibits the tremendous magnitude and effects that man-made climate change causes. All of these discoveries, combined with all of Balog’s pictures of glaciers which shows the rapid recession of glaciers, demonstrate how real man-made climate change is and how dire the consequences can …show more content…
As a matter of fact, according to National Geographic Editor Dennis Dimick, “people have a hard time understanding when we talk about climate change." His views dramatically changed after EIS and now, he is one of the leading figures in advocating for the recognition of man-made climate change. Furthermore, scientists have provided further proof for increased greenhouse gasses in the atmosphere which leads to climate change. They can drill holes in glaciers and remove a core, which consists of layers of accumulated ice from millions of years ago. These layers provide information of ancient air bubbles that were trapped in ice which reveal past temperatures and carbon dioxide content in the air from the past. Today, carbon dioxide levels are 40% higher than any naturally occurring level in the past and are increasing at over 100 times the highest naturally occurring rate recorded. Balog highlights how the physics and chemistry of the air are changing which leads to more natural disasters such as hurricanes and tornadoes. Although on paper, the temperature changes do not seem too drastic, it only takes a small change to cause massive changes on the environment, similar to how small amounts of steroids can have massive effect on the human body. These changes will continue to destroy our environment unless humans collectively make efforts to reduce such climate
In his essay, “Global Warming is Eroding Glacial Ice,” Revkin is arguing that global warming is constantly changing the ...
The environment has become a popular topic this year due to our on-going drought. It has always been a serious issue; something Saukko informs us in her sarcastic essay “How to Poison the Earth”. She uses sarcasm and irony in her essay hoping her readers will do the complete opposite of what she is saying because of the stress she puts on the harming chemicals we use every day. We do not appreciate our environment and take it for granted. This ideal is what Ehrlich's essay “Chronicles of Ice” focuses on by using analogies and scientific definitions to describe aspects of glaciers. The melting of the glaciers introduces us to the topic of global warming and how our society is doing nothing to stop it from getting worse. Gawande’s “The Cancer-Cluster
In the statistical distribution of weather condition and its perfect pattern in an amount of time ranging from decades to centuries to millions of years, a substantial, long-lasting and drastic change is largely known as Climate change. It may be a change in more or fewer extreme weather events or in the distribution of weather more or less the average conditions or in average weather conditions. With the usage of theoretical models and observations methods, scientists, experts and specialists in this particular field actively works in order to perfectly understand past and future climate under certain situation and circumstances.
The book by David Archer (2009) includes details that will make the readers understand the future of climate change as well as past events that have changed the present climate, as we know it. David Archer is a professor of geophysical sciences at the University of Chicago and has done many public presentations on the earth’s climate change before releasing his book, the long Thaw.
People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, “Global Warming Is Eroding Glacial Ice” by Andrew C. Revkin and “Global Warming Is Not a Threat to Polar Ice” by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes.
... and feed grains (Nyong, 2008). Higher temperatures can the physiological development of crops such as causing increased respirations, shorter periods of seed formation and reduced biomass production which all result in hastened maturation and reduced crop yields (Adejuwon, 2004). Global warming and drought have affected the change in the incidence and distribution of pests and pathogens which presents challenges for crop management and animal rearing. Moisture and temperature are important elements of climate which determine the occurrence and localization of pests and diseases (Adejuwon, 2004). This is because pests and diseases vectors thrive well in optimum conditions of high temperature and abundant water supply. In this way climate change and global warming has extended the range of distribution of some pests and diseases worsening the plight of farmers.
Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997). Indeed, glaciers present sensitive indicators of climate change and global warming and by estimating and monitoring the dynamic evolution of these ice masses, several aspect of climate change impact on environmental phenomena can be revealed.
Global climate change and its apparent effects have been the subject of much discussion for a number of years. It is often claimed that this change is too advanced and the damage caused by it is irreversible, meaning that any efforts by us to undo this are in vain. Although I agree that our planet has become unalterably changed, I don’t entirely concur that this change is now completely beyond repair.
Climate change is evidenced through shifts in the weather patterns such as winds, humidity and temperatures over certain durations. Natural climate changes occur less frequently and they are triggered by factors related geographical aspects as well as solar radiation. The earth’s movement on the orbit triggers changes in climate causing some areas to have higher temperatures than usual while others are significantly cold depending on the position of the earth on the orbit. The heat form the sun causes changes on the stratospheric ozone and it increases the amount of greenhouse gases. Heat from the oceanic crust also contributes to warming as a result of episodic hydrothermal venting (Liao & Sandeberg, 2012). Volcanic activity also causes a release of certain elements that may block the sun and also contribute to increase greenhouse gases in the atmosphere.
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues.

Glaciers have disappeared due to increasing in global temperatures because of which the water level had drastically increased and its causing flood all over the world
According to the Canada’s Action on Climate Change, Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events. Climate change is one of the biggest crisis in the earth. It will cause a huge damage to the eco-system and human. We are the victims of the climate change. However, we are the one who cause the climate change.
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. I...
While critical of global warming alarmism, this documentary does not doubt that the earth is warming. Instead, they claim that scientific evidence demonstrates that such warming is but a natural variation in earth’s climatic history, similar to the Medieval Warm Period of the Little Ice Age. The documentary uses several lines of evidence to back up this claim, including ice core data that they claim when rightly interpreted shows carbon dioxide as having a lag time when earth’s climate has warmed in the recent and distant past, making it doubtful that it could be responsible for the increase in temperature that has been observed recently. The timing of the recent warming, which was most pronounced in the late Nineteenth Century through World War II, stopped and reversed to a cooling trend in the mid-Twentieth Century, and then rapidly warmed again in the past three decades, is dissected. Since this warming began before the advent of major human sources of greenhouse gas emissions and the period of most dramatic industrial...
... of extreme weather and melting ice caps are indicators of global warming. Because these things will affect society, there are important decisions that have to be made in the present as well as in the future to secure people’s lives and lifestyles. The world community is aware of this serious issue and do already prepare for projects to slow down global warming, but they still have to improve. If the world leaders stop worrying about this issue, the future generations could be in danger. The future lifestyles will be affected by the decisions made in the present day. Society has much to improve to save energy and to lower greenhouse gas emissions. There are also small things people can do to help. Individuals can live a life without wasting energy or polluting the environment. Without effort, global warming endangers the quality of life for the future generations.
