What are some of the causes of climate change?
Greenhouse gases are not the only reason why the Earth is warming. Other things can cause climates to change. Learn why the Sun, and volcanoes can contribute to differences in the Earth’s temperature.

Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] JOAN CARTAN-HANSEN, HOST: What can cause a climate to change?
The shape of the Earth's orbit around the sun and how the Earth tilts on its axis both impact the Earth's climate.
Most of these changes happen in cycles that repeat over tens of thousands of years.
The sun goes through cycles every 11 years or so and those cycles change how much energy the sun releases.
And that can change Earth's climate.
Volcanic eruptions can have a big impact on the Earth's climate.
Eruptions send dust and gas into the stratosphere where they can limit the amount of sunlight that hits the Earth.
And human activities are causing the Earth's current climate to warm.
Burning fossil fuels add greenhouse gases to the atmosphere and that traps in heat.
And deforestation takes away trees that would otherwise reduce carbon levels.
Scientists study the chemicals in ice cores from Greenland and rocks from the ocean floor to learn how the Earth's climate has changed over time.
