What Causes Climate To Vary

September 13, 2019

First the amount of energy arriving from the sun and second the circulation of the atmosphere and oceans which carry heat and moisture from one placc to another. Burning fossil fuels Over the past 150 years industrialised countries have been burning large amounts of fossil fuels such as oil and gas.

Causes Of Climate Change

Climate Explained is a collaboration between The Conversation Stuff and the New Zealand Science Media Centre to answer your questions about climate change.

What causes climate to vary. What causes climate change. Slight or drastic changes to the Earths orbit affecting the amount of sunlight that reaches the Earths atmosphere Volcanic activity which can emit aerosols and carbon dioxide into the atmosphere thus increase greenhouse gases. If you have a question youd like an.

Here is a list of the many different natural occurrences that scientists say contribute to climate changes. Man-made Causes of Climate Change. Forcings are external processes that affect the climate system.

Orbital changes - the Earth has natural warming and cooling periods caused by Milankovitch cycles or variations in the tilt andor orbit of the Earth around the Sun Wobble roll and stretch. Atmospheric aerosols alter climate by scattering and absorbing solar and infrared radiation and they may also change the microphysical and chemical properties of clouds. Natural causes of climate change.

Essentially there arc two main reasons that climate varies from place to place. Geological records show that there have been a number of large variations in Earths climate. Climate data from volcanic events indicate that just one large eruption is enough to cause global cooling of around 03C and between 1 and 2 years.

Since the beginning of the Industrial Revolution these human influences on the climate system have increased substantially. We are accelerating the rate of climate change far past what the influence of the sun or any natural forcer could achieve. Processes in our daily lives are expelling chemicals and foreign substances into the air that affect and increase the natural greenhouse gases which then absorb more energy from the sun.

Forcing A forcing process changes the proportion of incoming solar radiation and outgoing infrared radiation that is kept in the Earths atmosphere and so changes the amount of energy within global weather patterns. These have been caused by many natural factors including changes in the sun emissions from volcanoes variations in Earths orbit and levels of carbon dioxide. Finally land-use changes such as deforestation have led to changes in the amount of sunlight reflected from the ground back into space the surface albedo.

Climate change can also be caused by human activities such as the burning of fossil fuels and the conversion of land for forestry and agriculture. What causes climate change. Climate change periodic modification of Earth s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic chemical biological and geographic factors within the Earth system.

The gases released into the atmosphere during this process act like an invisible blanket trapping heat from the sun and warming the Earth. One of the major factors determining the relative warmth of a climate is the angle of the sun in the sky. Volcanic activity is well known to change the climate.
