CLIMATE CHANGE
Facts
One way to reduce carbon dioxide is to use clean renewable energy sources such as solar energy and wind energy. These sources produce much less pollution as well.
It takes lots of data and many years to determine how the average temperature of the Earth is changing. Even then, many scientists disagree on how to interpret the data.
Since 1990, worldwide carbon dioxide emissions have risen by over 20 percent.
The United Nations formed a group called the International Panel on Climate Change to investigate global warming.

GREENHOUSE GASES
Greenhouse gases act like insulation to keep the Earth warm. However, as more and more greenhouse gases get into the atmosphere, the Earth will start to grow warmer.
The main greenhouse gases that keep the Earth warm are water vapor, methane and carbon dioxide.
In the past 100 years humans have been the cause of a significant increase in greenhouse gases in the atmosphere. Every time we drive our cars more carbon dioxide is released into the air.
SUN ACTIVITY
Since all the energy and heat on the Earth comes from the sun, it follows that the sun's activity will have some effect on the temperature of the Earth.
The activity of the sun is actually different over time, which can change how much energy actually hits the Earth.
VULCANOES
When volcanoes erupt they can change the temperature of the entire Earth for a short period of time because their eruptions send large amounts of ash and particles into the atmosphere.

Some scientists think that the current warming trend is just a part of the Earth's natural changes in temperature and it will eventually start to cool again.
