Difference Between Anthropogenic Climate Change And Natural Climate Variability

Global climate change and variability, particularly at regional levels, are not completely understood. Therefore, there are many significant

Climate change is a change in the average global or regional weather patterns. Climate changes includes factors such as; temperature, precipitation, humidity, wind and seasons, influenced by oceans, land surfaces and ice sheets. This plays a

The Earth has been experiencing a considerable amount of climate change for the last several decades. Natural factors that contribute to the climate system consist of: solar output, volcanic activity and earth’s orbit around the sun. The two factors relevant on timescales of contemporary climate exist in volcanic activity and changes in solar radiation. The earth’s energy balance primarily influences the amount of incoming energy from volcanic eruptions, which have a relatively short-term effect on climate. Changes in solar output have contributed greatly to climate trends over the past century. The effect of greenhouse gases in the atmosphere has been at least ten times that of changes in the Sun’s output and the ocean covers more than 70 percent of the earth’s surface, receiving twice the amount of earth’s radiation. Although the sun is the engine that drives all the weather, oceans and atmosphere control the sun 's energy along certain

The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.

on, there are other, natural forcings that have effects on the global climate. A few of these

Overall El Niño is a world wide phenomenon which affects countries in different ways depending on were they are situated and whether they are a LEDC or MEDC.

It is important to understand the various cycles our atmosphere goes through due to how they affect our daily lives. The ENSO Cycle has a large impact globally and locally in California as we have seen with the long-term drought Southern California is currently in. The ENSO cycle can be defined by sea surface temperature (SST) anomaly in the Pacific Equatorial Area known as Nino 3.4 region (5oN-5oS, 120o-170oW). Unusually cooler waters (-.5 degrees centigrade) occurring for three consecutive months outlines a La Niña. La Niña’s bring wetter weather to Australia and Indonesia but often leaves the Eastern Pacific dry. Unlike La Niña’s, unusually warm water (+.5 degrees centigrade above average) occurring for 3 consecutive month’s outlines an

el nino is a warm band of water that periodically develops in the Pacific Ocean near the equator off western South America. El Niño—Spanish for “the child” because it often occurs around Christmas—occurs about once every two to seven years. El Niño can affect the weather in large parts of Asia, Africa, Indonesia, and North and South America, causing both floods and droughts. An El Niño event is often followed by a band of colder than normal ocean waters called La Niña, which is Spanish for “the girl.” La Niña produces the opposite weather conditions. Both of these phenomena cause changes in air pressure in the western Pacific. Together these two events are known as ENSO, or El Niño–Southern

1.2.2 Changes in rainfall patterns --- droughts and fires in some areas, flooding in other areas. See the section above on the recent droughts, for example!

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).

When you hear the words “climate change” what comes to mind? Probably weather and the changes. Many of us watch the news or use an app on our cellphones/electronic devices to keep an eye on the weather for the day, week, or even the month. But, there is actually a difference between weather and climate. Weather is actually “the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Weather also changes from place to place” (Dunbar, 2014). Whereas “climate is the usual weather of a place. Climate can be different for different seasons. Different places can have different climates” (Dunbar, 2014). This paper will focus on the ins and outs of climate change, specifically focusing on what climate change

The UNFCC also defines climate change as “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over time periods.”

Over the years there has been a lot of controversy on if climate change is an issue that needs to be discussed and solved. There is a constant debate among scientist on if human actions are contributing the changing of earth’s climates. Climate change is defined as the change in average weather patterns for a specific region or Earth as a whole. This could include the change in an average temperature for a city or the amount a rainfall it receives (Dunbar, 2015). The main difference between weather and climate is the period of time specific patterns are recorded. Weather patterns are looked at over a much shorter period of time, meaning that these patterns are going to be more sporadic and change more frequently. Climate on the other had is recorded over a much longer period of time and usually show less drastic changes in patterns when compared to weather. Some people may argue that climate change is not an issue because Earth’s temperature is always changing do to natural effects. What people don’t realize is that human activity has effected the rate that earth’s temperature is changing, and just the smallest changes can lead to drastic consequences (Dunbar, 2015).

Earth's climate is always changing. Many factors can contribute to the cause of changes in Earth's energy. Some changes in climate change are natural. It includes changes in Earth's orbit and the amount of energy coming from the sun. Also, ocean changes and volcanic eruptions are natural causes of climate change.

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
