Major causes of climate change

 
 
Our activities are the cause of climate change. Chopping down forests, burning coal, oil, gas, and land clearance are the main ones. When we burn these fossil fuels large amounts of carbon dioxide (CO2) get released. This CO2 accumulates in Earths atmosphere. Deforestation reduces the number of trees available to consume excess CO2.
 
 
Increases in CO2 and other greenhouse gases prevent solar radiation from escaping. This traps heat and raises the temperature on Earths surface. This is the “Greenhouse Effect.”
 
The greenhouse effect keeps Earth warm and habitable. Unfortunately, human activities intensify the heat causing the planet to overheat. This the “Enhanced Greenhouse Effect.”

Impacts of a warming climate

Different regions on our planet experience different effects of climate change. That is, the temperature rises at different rates depending on the region.
 
Many areas experience unpredictable and extreme weather events. Some become colder or drier. Others may become wetter or hotter.
 
Projections by the scientific community say that our climate could raise by as much as 6 in the next 80 years. Cutting carbon emissions could, at least, lessen this.
 
An increase of 6 is likely to affect crucial food chains and fragile ecosystems. This would result in massive rain-forest destruction. Sea levels will rise by large amounts. Ice sheets will also melt in our polar regions.
 
As a result, we and other life on or planet would suffer greatly.
 
I will look at the effects of climate change on wildlife in my next post.

Climate Change

Climate is the typical or average weather recorded over a period of time in a given or set region. Weather anomalies occur such as a cool day in summer, or a warm day in winter. Those events do not show climate change. Trends observed over long periods of time prove climate change is occurring right now.
 
Our planets climate has changed over it’s 4.5-billion year history. During this time, Earth has warmed and cooled over several periods.
 
Observations prove Earths climate has altered in the last 100 years. These observations are by the scientific community.
 
In Australia, our average temperature is up by around 1%. Even this small change is a rapid one. This speed of change does not provide animals, plants and us to adapt. Thus the delicate balance of Earth’s ecosystems become affected.
 
In my next post, we will look at what the major causes are of climate change.
