=What are the natural causes of climate change?=


 * Main theories behind natural causes of climate change;**
 * **Continental Drift**
 * **Volcanoes**
 * **The Earth's Tilt**
 * **Oceans Current**

Scientists have speculated many different causes of natural climate change. A few are: []
 * The sun spots are exploding, raising the heat.
 * Large eruptions in the major volcanoes on the earth - increasing gases and damaging plants
 * The orbit the Earth takes has changed - movement to or from the sun
 * The Earth is different when compared to how it sits near the sun -changes the temperature up or down
 * One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere.
 * Explosions on the sun generate more heat then the sun would normally give off; this heat makes it to the Earth, causing rising tempuratures.
 * Any slight change in the Earth's orbit can cause the Earth to move closer or further away from the sun. This can radically change tempuratures becuase the Earth will be closer or further away from its source.
 * Volcanic eruptions can cause tempuratures to decrease because the smoke prevents sunlight from reaching the Earth.

The ocean makes up 71% of the earth so it has a great effect on the climate patterns and changes in climate.
 * Most people** **feel that climate change is just caused by human activities. While humans are a factor in the change in temperatures they are not the only one. For example every time a volcano blows it shoots out tons of sulphur dioxide and other gases that are harmful to the earths atmosphere. These gases stay in the air for years after the volcano has blown. The dust and gas particles partically block the suns rays causeing the earthe to cool slightly. Also the particles get into the atmosphere and cause a greenhouse gas effect which in turn warms the earth. The ocean also plays a major factor in climate change.** " Ocean currents have been known to change direction or slow down. Much of the heat that escapes from the oceans is in the form of water vapour, the most abundant greenhouse gas on Earth. Yet, water vapor also contributes to the formation of clouds, which shade the surface and have a net cooling effect." ([])

Some factors that have been known to create climate change over the past hundred to millions of years are
 * energy output from the sun,
 * variation in the earth’s orbit and the orientation of its axis,
 * the greenhouse effect of water vapour and other trace gases,
 * volcanic and meteorite activity and plate tectonics
 * moving of the continents


 * The earth would be much cooler if it werent for greenhouse gases (CO2 and other gas emmisions) that are trapped in the earths atmosphere that help keep in heat given off from the sun.**

For climate change on the earth is because the continents greenhouse gases (CO2 and other gas emmisions) that are constantly moving. They were once all together about 200 million years ago. The earth looked completly different at this point in time. Since the continents are seperating still it causes a change in the wind and ocean patterns. This in turn can cause climate changes in different area's. An example of how the continents are still moving is the Himalayan mountain range is growing about 1 mm per year. These stuctural changes in the earth can casue serious climate change. The trapped in the earths tilt can also be a factor in its climate change. It can cause a change in the natural whether patterns of the earth. atmosphere that help keep in heat given off from the sun.

Another reason for climate change on the earth is because the continents are constantly moving. They were once all together about 200 million years ago.

The earths tilt can also be a factor in its climate change. It can cause a change in the natural whether patterns of the earth.
