What are the Causes of Climate Change?

The majority of climate scientists agree on the main causes of climate change.

A Warming Atmosphere

Climate change is caused by an increase in greenhouse gases which include:

These gases are responsible for the greenhouse effect which is responsible for warming the troposphere, the lowest layer of the atmosphere.

Air pollution is responsible for millions of deaths each year, and also contributes to the greenhouse effect

Carbon Dioxide: the Fundamental Cause

Carbon dioxide takes up a small percentage of these gases.

Even though they do not make up a large part of the atmosphere (only 0.039% ), they are very important nevertheless.

This gas is naturally emitted through cellular respiration and volcanoes.

By these natural processes alone, carbon dioxide will increase/decrease very slowly over time or remain constant.

Animal and marine life that have decomposed over millions of years turn into fossil fuels which include coal, petroleum (oil) and natural gas.

Mankind is releasing about 90 million tons of carbon dioxide into the atmosphere each day, as if it were an open sewer.

Mankind has released great amounts of carbon dioxide into the atmosphere as if it were an open sewer

Mankind's Contribution to the Problem

However, mankind has drastically increased the concentration of carbon dioxide from 280 parts per million to 392 ppm in the last 200 years.

This rapid change of carbon dioxide will have several effects on humankind and precious ecosystems.

Mankind has burned these fossil fuels to harness its energy to do work. The carbons released from the combustion of these fossil fuels combine with oxygen in the air to then create carbon dioxide.

Combustion of fossil fuels is not sustainable, and will bring along severe consequences

Specific Causes to Global Warming

Carbon dioxide is mainly emitted because of

The tar sands in Alberta, Canada's worst environmental disaster, contributes an incredible amount of greenhouse gases every day.

Moreover, environmental catastrophes such as the Gulf of Mexico oil spill also contribute to global warming.

By reducing our carbon footprint, we can help solve the climate crisis. A carbon footprint is how much carbon dioxide we emit directly or indirectly in our daily lives.

Transportation is one of the ways in which we emit carbon dioxide into the atmosphere

What now?

At this point in time, there is a substantial amount of evidence regarding the causes of climate change.

Fortunately, there are many ways you can help stop climate change.

By spreading the word and taking these initiatives to reduce your carbon footprint, you can help make the world a better place.
