Climate Change And Current Geological Period

Climate change is defined as the change in global or regional climate patterns, which is apparent from the mid to late 20th century onwards. When looking at climate change there is an abundance of evidence that supports that humans are the leading causes of the drastic shift in the weather pattern but there is also a lot of evidence against humans actually causing climate changes. For example, the increasing levels of man made gases that are let into the atmosphere may have created a greenhouse effect, which traps heat and ultimately causes global warming. But there are also many scientists who believe that the earth has always naturally cooled down or warmed up at its own pace.

Climate change is the change in average weather of a region. Climate change can be, for example, change in region’s average annual rainfall or change in region’s average temperature for certain period (May, 2011). In a broader view, climate change can also be seen as change in Earth’s climate with an example being global warming.

Climate change can be defined as a significant change in the “average weather” of any given region sustained in the long-term and can be caused by Earth 's dynamic processes, external forces including variations in sunlight intensity, and also by human activities (USEPA, 2014).

Climate Change is the significant change in the climate and distribution of weather patterns on Earth ranging from the last decade to millennia earlier.

Climate change can be defined as a long-term change in weather environments that include wind, precipitation, and temperature. The direct result of climate change can lead to a change in weather patterns that can last for extended periods of time (Climate Change Summary). Climate change may also be referred to as a change in average weather conditions, which could lead to an increase or decrease in extreme weather events. Recently climate change has been recognized as a problem around the world, while other groups believe climate change is made up of fictional data. Climate change is an ongoing problem in the scientific community, but society has not fully accepted the principles of climate change.

Climate change is defined by Dictionary.com as “A long-term change in the earth’s climate, especially a change due to an increase in the average atmospheric temperature” (“The Definition of Climate Change”). Climate change can be separated into four categories which are: evidences, causes, effects, and solutions. These categories help to find out what climate change is and how we can stop it.

The main contributor to climate change is the human race, but there are some natural factors that are contributing as well as humans. Volcanic eruptions and changes in irradiance can be factors that influence climate change. Although they can cause changes to the climate, they are short term

Variations in the behaviour of the weather over long time periods, such as from one century another, are referred to as climate change. Climate itself adjusts from the times of 'ice ages,' hen huge ice sheets covered large areas that are currently ice-free, to periods similar to today hen ice sheets are largely confined to Antarctica, Greenland, and the floating Arctic sea ice. Paleo-climate records indicate that much of the climate changes over the last two million years occured in a rather cyclical manner; with glacial periods lasting roughly 100,000 years with warmer interglacial periods of 10,000 years occurring in between.

Climate change is defined as “a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.” Climate change has happened as a cycle throughout history, with ice ages occurring, and then warming. The earth naturally warms and cools, but due to the burning of fossil fuels the rate is growing exponentially.

Climate change is a large scale change in the planet’s weather systems or its average temperature. The Earth’s climate may change within varying timescales in response to natural factors. On the scale of tens of thousands of years the climate changes through glacial and interglacial periods; whereas it changes through the timescale of years occurs due to the effects of El Niño and La Niña which temporarily change the Earth’s temperature and regional scale weather patterns.

Climate change is the subject of how weather patterns change over decades or longer. Climate change takes place due to natural and human influences. Since the Industrial Revolution (i.e., 1750), humans have contributed to climate change through the emissions of GHGs and aerosols, and through changes in land use, resulting in a rise in global temperatures.1 Increases in global temperatures may have different impacts, such as an increase in storms, floods, droughts, and sea levels, and the decline of ice sheets, sea ice, and glaciers.

Climate change is when there is an identifiable change in weather over time. Unlike weather, scientists can predict the climate for the next fifty years; they can predict the changes in the atmospheric composition and the long-term weather in a certain area. Climate change is the predicted average weather and the change in an average weather, also known as the different temperatures, seasons, and precipitation. Climate can be viewed within the entire Earth itself, rather than just one place. This means that the Earth can have changes in the atmosphere, land, oceans, precipitation, and land. The Earth’s climate is always changing. An example of climate change within the entire Earth, between summer and winer. The seasons change because of geographical patterns of energy absorbed and radiated away by the Earth. Climate changes are formed by the changes in heat energy in the Earth’s system. Human activities are also a major factor to climate changes. Humans have made various changes in the amounts of greenhouse gases in the atmosphere, as well as changes made in the land.

Climate change is the process of change in average long term weather patterns. These long term changes can be limited to small local areas such as cities or countries, large broad areas or cover the overall climate of Earth. Climate change occurs naturally due to the orbit of the Earth, ocean changes, changes in solar radiation levels and volcanic disasters. Although these natural influences do play a part in climate change most scientists believe that the rate of climate change that the Earth has experienced recently is not an entirely natural occurrence. These scientists believe that humans are having a large impact on recent climate change. Climate change that is influenced by human activity is called anthropogenic climate change. Anthropogenic climate change is caused by the emission of greenhouse gases into the atmosphere. Greenhouse gases are heat retaining gases that over time collect in the atmosphere. Some of the most common greenhouse gases that are having a large effect on the rate of anthropogenic climate change are carbon dioxide, methane and nitrous oxide. When these gases are emitted they cause the atmosphere to become thicker and retain more heat from the sun. The process of these greenhouse gases collecting in the atmosphere is causing the temperature on Earth to increase. The two main causes of anthropogenic climate change are the burning of fossil fuels and deforestation. Burning the fossil fuels coal, oil and gas releases carbon. Trees naturally absorb

In the past Earth’s climate has changed depending on the amount of incoming and outgoing energy. The significant factors that contribute to the Earth’s natural climate change can be determined by the Earth's path around the sun, the output of energy from our sun, the ocean’s normal cooling and warming cycles and the continual unpredictability in volcanic activity. An example of natural climate change would be El Nino which relied on the natural winds and ocean currents.

Scientists have discovered 'climate forcing’s ' influence variations in climate systems and based on the depth and period of such forcing’s the adjustments to climate may be in a shorter or longer earth cycle. Natural forcing’s like variations in earth 's orbit, solar variation, volcanic eruptions and motion of tectonic plates have influence on the Earth 's climate
