Climate change is when there are different measures of climate during a period of time. It includes, big changes in the weather regarding temperature, wind patterns and more that occur over several years. (EPA, 2014)

The term sometimes is applicable to climate change caused by human activity, as opposed to changes in climate that were a result of the natural processes of the Earth. The words Climate change now has the same meaning as anthropogenic global warming. (Conway, 2008)

Observed Changes in the Climate System
When the climate system was reviewed and looked at, it showed that warming of the climate system is absolute and since the 1950 s, many of the observations that were made show that changes are unusual over decades. (Seattlepi Weather, 2014)

• Atmosphere:
The Earth’s surface has been continuously getting warmer over the last three decades. This period of time was warmer than any previous decade since 1850. In the Northern Hemisphere, the period between the 1830s and 2012 was the warmest 30-year period of the last 1400 years.
• Ocean:
The increase in energy, stored in the climate system is effected and dominated because the ocean is getting warmer. It accounts for more than 90% of the energy stored between 1971 and 2010. Researchers and practitioners are practically certain that the upper ocean (0−700 m) warmed from 1971 to 2010, and it probably warmed between the 1870s and 1971.

• Cryosphere:
