The Medieval Warm Period And The Little Ice Age

These are called warming, or cooling periods. Currently earth is in a warming period, it’s natural. We have had 5 warming periods already and they go way back in time. So far the one we are in right now, is the only one that has involved humans. The evidence in graphs can prove that there has only been one warming period with humans.Our earth didn’t just start changing it’s climate.Climate change has been happening for millions, even billions, of years. It’s not important to us, we shouldn’t be worrying. Even scientists know this, “The world's climate has been changing for the past 20,000 year.” It’s most likely, been happening for even longer than this time. We aren’t the only things that contribute to climate change, theres tons of other things that emit carbon and other gases into the atmosphere..“The change in the orbit affects the heating of the earth... This can last from 10,000 to 100,000 years.” The reason it’s changing the heating is because earths orbit is usually in a circle, but it sometimes changes to an oval like orbit. When the orbit is “Oval like,” it’s closer to the sun. Therefore the earth is heated more, in some spots, when it’s in this orbit. These are some of the simplest reasons to prove my point, but there are plenty out there, look for

It removes the time needed for adaptation and causes a great loss of life in the process. Globally, millions due to the direct and indirect influences of the little ice age. Every major death event and war during this period from the black plague to Napoleon’s failed campaign into Russia, the French revolution, and the Irish potato famine are tied to the little ice age. The little ice age was preceded by a warmer wetter period that allowed people to become reliant on certain crops and weather patterns for their survival. Several events occurred within a short period of time to start this cooling period that lasted 500 years. The warm period called the medieval maximum actually set events in motion. It is hypothesized that this warm period melted global ice packs, introducing a large volume of fresh water into the ocean interrupting the thermohaline flow. This stopped warm water from reaching the northern climates and therefore the atmosphere grew colder because of this. The second circumstance was the Maunder Minimum. This is a period of dormancy for sunspots. This results in less radiation reaching earth and less warmth available. The third event was actually a series of events. Volcanic eruptions started with a regularity of five major eruptions every century. This put a large amount of ash and water vapor into the atmosphere which in turn reflected the sunlight, deepening the cooling

“More than a million species face potential extinction as a result of disappearing habitats, changing ecosystems, and acidifying oceans” (Berger). Climate change affects all living things on the earth and is accelerating because of human activity. Climate change is happening right now, scientists are trying to figure out what is causing it, what the effects of climate change are, and they are researching how the atmosphere has changed.

Recently, there has been a warmer climate change, causing earth to get warmer, as well as negatively affecting earth, animals, and humans. Since 1880, the average temperature of earth has risen about 0.8 degrees celsius, which is a drastic change, even though it may not seem like much. Also, there has recently been a large amount of greenhouse gases being released, which is a large cause of why earth is getting warmer. Many consequences come with this change in climate. The fast-changing climate on earth has caused countless consequences that could permanently affect the earth.

The Earth 's atmosphere has changed all through history. Just in the most recent 650,000 years there have been seven cycles of frigid progress and withdraw, with the sudden end of the last ice age around 7,000 years back denoting the start of the present day atmosphere period and of human development. The greater part of these atmosphere changes are credited to little varieties in Earth 's circle that change the measure of sun based vitality our planet gets. Exploratory proof for warming of the atmosphere framework is unequivocal. The present warming pattern is of specific criticalness in light of the fact that the vast majority of it is likely human-impelled and continuing at a rate that is exceptional in the previous 1,300 years. Earth-circling satellites and other mechanical advances have empowered researchers to see the comprehensive view, gathering a wide range of sorts of data about our planet and its atmosphere on a worldwide scale. This group of information, gathered over numerous years, uncovers the signs of an evolving atmosphere. The warmth catching nature of carbon dioxide and different gasses was shown in the mid-nineteenth century. Their capacity to influence the exchange of infrared vitality through the environment is the logical premise of numerous instruments flown by NASA. There is no doubt that expanded levels of nursery gasses must bring about the Earth to warm accordingly. Ice centers drawn from Greenland, Antarctica, and tropical mountain icy masses

The debate is over. Yes, Earth’s climate has always fluctuated and drastically variable eras of weather is far from an unusual notion, but it is the unprecedented pace at which it is all currently occurring that is of most potent concern. Even the dastardly right-wingers, who’ve tactically denied climate change for so long, have joined an overwhelming scientific consensus about anthropogenic atmospheric deterioration. Data from the past century has revealed blatant indications of natural systems breaking down; i.e.: the oceans, used by Earth as a primary mechanism in cleansing atmosphere of CO2 and seemingly slight temperature shifts are ensuing extreme consequence.

Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009,

“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.

The natural gases that are trapped in the atmosphere that warms the earth and keeps earth climate livable is commonly known as the Greenhouse effect.

Due to global warming , the Arctic is warming much faster than the average global temperature; ice in the Arctic Ocean is melting and the permafrost is thawing. Since 1880, after carbon dioxide emissions took off with the Industrial Revolution, the average global temperature has increased about one and half degrees Fahrenheit. Each decade gets warmer than the last. A conference organized by the Geological Society in London in 2010 to evaluate how climate changed effected the earth before this time. The Geological Society warned that it could take the Earth one hundred thousand years to

What could have possibly gone wrong? It was the early fourteenth century, the Church had unified most of Europe under Christianity, and all seemed to be going well, (as well as one could be in the Middle Ages). So what went wrong? Climate change, or the “little ice age” as historical geographers call it. This change bought on bad harvests and a great famine, and like the butterfly effect, in was only downhill from there. Doubt in the Church’s performance, violence throughout social classes and the bubonic plague eventually added up to bring on the decline of medieval

The reading states that several possible causes have been proposed what caused the Little Ice Age and provides three reasons of support. However, the professor states that the authors' reasons are outdated and opposes each of the authors' reasons.

Global climate change has already had observable effects on the environment and the consequences of it has caused: glaciers to shrink, ice on rivers and lakes are breaking up earlier, increase of drought and flood increases, stronger storms and storm damage, economic losses, heat related illnesses and diseases plant and animal ranges have shifted and trees are flowering sooner.

Climate change has been research for many centuries; as early as the Ice Age. Obviously throughout the years, many researchers have had many ideas and those ideas about climate change have changed over the years. At this time I feel that I’ll give the current findings about how the research of climate change is observed.

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.
