Ice Cores Predict Future Climate

The amount of ice that is formed and melted the year before, helps set the stage for the ice that will be present the following year. So, with the warm temperatures and the lack of ice, studies are not showing very promising results for the upcoming

In chapter 11 of the textbook Ruddiman talks about two main greenhouse gases CO2 and methane and how they stayed around in our atmosphere, ice sheets, and land for thousands of years. He states that cores of todays ice sheets contain vital climatic signals which can be found under the center of an ice sheet. Drilling these ice sheets can take longer than a single summer, but in the end this information is crucial. Scientists look at carbon isotopes to determine how carbon has moved along time. Ruddiman states they move in two forms, organic carbon and inorganic carbon. He also says that when the ice sheets were large in size carbon dioxide concentrations were low, but when ice sheets were small or nonexistent then CO2 was higher. There are

by reconstructing how it changed across time periods when the Earth was warming," said the

Balog was once a skeptic of climate change as he believed that the theory surrounding global warming was based off of computer models. Furthermore, he did not believe that humans could alter the world’s climate on such a global scale. However, through studies of ice records, long tubes of ice drilled from the ground, Balog found key evidence suggesting ideas contrary to his prior beliefs. These glacial tubes preserved historical records of the past similar to the rings of a tree, recording past temperatures and CO2 levels. Using these records, one can see the direct variation between temperature and CO2. Additionally, the recent spike in both

Climate change has been in effect because of the rising temperature. The ice caps have been melting which proves that temperature and the Earth has been warming from Nasa. There has been a rise in temperature, in 2000-2009 has been documented as the hottest year on record according to www.skepticalscience.com. This supports climate change because there has been records of the hottest year on record which proves that climate change is in effect. Ice caps have been melting which supports that the Earth is warming and causing the ice caps to melt and rise the sea levels.

“The Glacier, and with it the Duck, might have moved since then.” Lou Sapienza is the lead organizer of a Coast Guard Operation searching for a missing World War II plane; the Grumman Duck and its lost crew. A challenging problem the party has with finding the Duck is the movement of glaciers since the planes went down close to 70 years ago. Since the 1950s the extent and the movement of the ice sheets have rapidly changed due to Global Warming. Most affected by this climate change is The Arctic, Antarctica and the Greenland Ice Cap. Lou Sapienza and his team of specialists only have a hand-drawn map of where the Duck crashed and an old radar survey from years ago. Their daring task is to predict how the movement of the ice sheet accelerated by global warming might have moved their missing plane. Since global warming is a problem, everyone will be affected by it in one way or another. It is time to act, to confront the problem and find a solution.

Ice cores: isotopes can help determined the temperature at the time ice was deposited as snow. Additionally, through air bubbles trapped in the ice one can analyzed the measure carbon dioxide and methane was absorbed as bubbles trapped in the ice.

The Earth has not always been as it is today. Periods of climate alterations have occurred over time to land us where we stand today. Around 8200 years ago or 6200 BCE, a surprising event occurred on Earth. The Earth underwent an abrupt climate temperature change. This change is known as the 8.2 ka year event or 8200 year event which refers to the last major climate alteration, a Northern Hemisphere cooling event that occurred approximately 8,200 years before the present. This event was less severe than the Younger Dryas, a cooling event preceding the 8.2, but more severe than the Little Ice Age that occurred after. The event occurred in the Greenland Ice cores during the Holocene, a period in which the Earth had a relatively stable climate.

The sun power and warm’s are earth, as two thirds of solar-energy enter our atmosphere as visible-light, the greenhouse effect absorbs the solar-energy to keeping the earth warm and later releases one third back into outer space. Without the “natural greenhouse effect” the earth's temperature would be below 32 degrees fahrenheit (The freezing point of water). The burning of fossil fuels as an energy source releases a variety of gasses such as Methane, nitrous oxide, and CO2 adding to the greenhouse effect. Because of this heat is kept longer, warming our atmosphere and causing what we know as global warming. One of the issues with global warming, is the destruction of ice polar caps that contributes to the rise of the ocean level, and causes

There is lots of evidence from fossils to show how climate change changed over Earth’s History; this enables us to see how climate change has changed over time. We are able to do this through looking at forams, plant and insect fossils and

The Ice Chronicles is an in-depth look at one scientists story of drilling for ice cores in arctic climates. The book also describes how the ice cores are drilled and how the ice cores are processed. The team of scientists use the ice cores and the chemical composition of them to get a better grasp of past climates and climate changes. The main drilling mentioned is the Greenland Ice Sheet Project that was overseen by many agencies and supported by multiple higher-education institutions. The project took many seasons and the teamwork of many top scientists from many top universities and research organizations. The data recovered from the thousands of meters of drilled ice contained the answers to many questions pertaining to the climate of now and the way the world climate once was. The drill was positioned at the very top of a glacier in a spot that was studied closely to make sure the project could yield the most accurate data for observation. The project took place in the early 1990’s and was completed by the 2000’s, but the data collected will help serve the world population for lifetimes ahead. The research conducted proves that humans have had some impact on the global climate, and also proves that the world goes through natural climate changes that last longer than human population has ever inhabited Earth.

Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives.

Climate change can lead us to the next Ice Age or the warmer the earth get by climate change it can cause major droughts. It can also cause a major flood and global warming, think about Florida and other states surrounded by water. It cost millions and millions of dollars to fix these states, now estimate the cost for the whole world. Think about the people is injured or lost their home. Where would they go?

There are a few way that scientist study the earth’s past atmospheric conditions but there’s only one I’m going to cover, the Ice core measurement. This method involves analyzation of the glacial. It provides scientist with a pretty precise estimate of past conditions that can compared against Earths present. The ice core measurement was introduced in or around 1960 and has been pretty valid. Data is collected by drill deep within the glaciers and collecting large blocks of Ice. Scientist analyze and preserve Ice from glaciers across the world for analyzation and comparison of earth’s current and past conditions.

I. (Main Point = Need) According to NASA climate is made up of two things. Those two things are the climates of certain locations during the different seasons and the Earth’s climate which is a combination of all those different induvial climates.
