As Arnold Schwarzenegger once said, “We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over” (Schwarzenegger, par.9). Has our society really made an effort to prevent global warming from evolving into a bigger disaster than it already has or are people sitting back and letting things unfold similarly to a series of unfortunate events? Andrew C. Revkin, the author of “Global Warming Is Eroding Glacial
global warming could cause another ice age, I have divided this paper into segments. The first will explain what the thermohaline circulation cycle is. Next, I will look at the last interglacial period and observe what the conditions were like especially in respect to the THC. I will look at how the last interglacial led to the last great Ice Age, and the sudden demise of that Ice Age, as well as the nearly equally sudden cooling that occurred in the Younger Dryas about 12,000 years ago before the
Earth has experienced many eras with different climates. Earth’s climate continually cycles through ice age periods and interglacial periods, due to its orbit, the varying energy produced by the sun, and natural disasters like volcanic eruptions. According to the UXL Encyclopedia of Weather and Natural Disasters, the history of Earth’s forever changing climate is separated into six main time periods: the Hadean, Archaean, Proterozoic, Paleozoic, Mesozoic, and Cenozoic eras. The first three eras are
able to gather significant information about past climate changes, and future climate changes. For example, for around the past 12,000 years, we have been lucky enough to live in an interglacial period, in which we are able to live in a warmer climate. From the data collected, scientists estimate that this interglacial period will last for another 15,000 years. However, this may not be the case if human activities gravely alter the Earth's climate. The impact humans have caused towards the Earth can
from the equator to the pole have a substantial difference, and there is covering on large areas of the earth by continental- size glaciers. Ice age is the individual's pulses of cold climate, whereas the irregular warm periods are referred to as interglacial. Ice age entails the extensive presence of ice sheets both in northern and southern hemispheres in glaciology terminology,
033216 Ms. Sheridan/Mr. Whittard SNC2D-2/CGC1D-3 April 2014 A Study of the Changes in Natural Disasters due to the Effects of Climate Change in the Republic of the Philippines Introduction In 1927, for the first time in history, the world’s population reached two billion people. In 2011, less than one hundred years later, it passed seven billion (Worldometers). Some may think that this is a positive increase, creating economic growth and significant innovations in fields such as agriculture, industry
Climate is the average weather conditions present in a particular area over a long period of time. Earth’s climate is an intricate system that is essential to our livelihoods. It is for this reason that scientists, such as paleoclimatologist, are hoping to better understand future climate conditions by studying the Earth’s past and present climate conditions. There are two types of data available to scientist studying past and present climate conditions. The first is instrumental data, which is
A Flawed Opinion Whenever someone thinks of CO2, they think of global warming. They are reminded of Al Gore and his stance on global warming and they automatically think it is true. He has a lot of evidence to back up his theory about how global warming exists and that it is the reason animals are going extinct and also why the climate is changing. Well these facts are wrong and there is evidence to prove it. Global warming is not real and the Earth might even be in a cooling period. There so
Climate Change: A Greenland Perspective Works Cited Not Included Climate change is the alteration of temperature and precipitation patterns over an extended period of time. Across the globe, scientists are identifying climate change in relation to the greenhouse gas emissions and solar cycles. While most researchers believe that the increase of atmospheric CO2 is effecting global warming, others are endorsing the concerns of another Ice Age, which is likely to occur due to orbital variations
In the nineteen-teens, as World War I raged across Europe, Milutin Milankovic, a Serbian astronomer and prisoner of war, was busy computing the gravitational force of planets like Jupiter on the Earth’s tilt and orbit. He had an idea that the amount of solar radiation that reaches higher latitudes could trigger an ice age or warm up the Earth. He believed that slow changes in the Earth’s orbit contributed to the amount of solar radiation reaching a particular latitude. By the end of the war, his
concerned to inform the public about. Interestingly enough, some of the mistakes our esteemed presenter made were crucial details that weaken the anthropogenic global warming argument. In the film, Gore mistakenly asserts “that in each of the last four interglacial warm periods, changes in carbon dioxide concentration caused changes in temperature” (35 Inconvenient Truths: The Errors in Al Gore's Movie) . In reality it’s the opposite, because temperature is the factor that affects carbon dioxide levels. “Carbon
over the last 700,000 years. Throughout this time period, there have been a series of glaciation cycles lasting around 100,000 years each. The cycle begins with 90,000 years of cooling, known as an ice age, followed by 10,000 to 12,000 years of interglacial warming. The average temperature of the last ice age we had reached about 9 to 12.6 degrees Fahrenheit cooler than it is today at its lowest p... ... middle of paper ... ...sion=1.0>. Bob Carter.

threat to the world. However, in the essay “Cold Comfort for ‘Global Warming’,” Phillip Stott makes the complete opposite argument. He argues that global warming is nothing to be worried about and the melting of the polar icecaps is caused by the interglacial period we are currently in. After reading both of these essays and doing extensive research on both viewpoints, I completely agree with Revkin that global warming is an enormous threat to our world today. My research not only helped me to take
The statement in question for this assignment puts forth various assertions: that the Little Ice Age cooled the climate worldwide, that it wasn’t the coldest period since the last ice age, and that because the earth is in a natural time of warming from this period, human-made greenhouse gasses are not plausible as a source of global warming. Some of these statements are true, but there are also fallacies within these assertions. The Little Ice Age is the name for the period of cooling spanning from
Effects of The Pleistocene Epoch on Colorado INTRODUCTION Glaciers are an integral part of the world’s climate. In fact, as Richard Armstrong of the University of Colorado says, “Glaciers are key indicators in monitoring and detecting climate change” (Univ. of Colorado, Boulder, 2003, p. 1). Not only are they an important part of monitoring current climate, they can hold many keys to the past. Glaciers are in fact, “a source of paleoclimate data…” (Meier and Dyurgerov, 1980, p. 37). This
to having the same indistinguishable features that modern man does, originated more than 130,000 years ago. This resurgence of life is hard to pinpoint and follow due to different ice ages. It is clear however that when the Eemian and Holocene interglacial periods began, due to warmer climates, traces of culture were first detected. Humans jumped through this “window” where other species did not. Cook goes on to describe the exact anatomy of the human biome. He uses DNA examples to further his idea
sea-level rise might be irreversible. For this reason, the Greenland ice sheet is often described as a relict ice mass. It survived the current Holocene interglacial solely because it creates its own cold surface-climate because of its elevation. The last time Greenland temperatures were several degrees higher than today was the last interglacial 125,000 years ago. Ice core evidence for a smaller ice sheet is consistent with the observation that sea level then was several meters higher than today
Carbon dioxide is an important gas that is vital for plant life. This compound is made of a carbon atom and two oxygen atoms. Only 0.0397 of the atmosphere is composed of carbon dioxide. Even though carbon dioxide only makes up a small percentage of the atmosphere, lately increases in the amount carbon dioxide released into the atmosphere have shown to cause an adverse effect on the earth. The rise in amount of carbon dioxide in the atmosphere has caused the earth’s temperature to steadily rise.
new nor unusual. Throughout the history of the earth, the average surface temperature, climate and greenhouse gas concentrations have changed, sometimes gradually other times quite sharply. During the past 10,000 years the earth has been in an interglacial period with a fairly stable climate, surface temperature, and greenhouse gas concentration1. The problem that has arisen in recent times is when scientists analyze the past 150 years, especially the last 50. Scientists have found an increased
Imagine the world where modern humans and Neanderthals coexisted. The two groups lived among each other for some 2,600 to 5,400 years (Wong 2015, 43). For a long time, it was said that Neanderthals are our closest relatives. There is DNA evidence that shows Neanderthals and modern humans are closely linked. Around 39,000 years ago, Neanderthals suddenly disappeared from the face of the Earth, shortly after the first modern humans appeared (Wong 2009, 33). With the help of researchers, there have
