Climate Change Essay

Climate change occurs when there is a significant variance in the climate which last for several decades or longer and not for a short period of time. Climate change includes changes in elements such as temperature, precipitation and wind patterns.

People tend to use this phrase to refer to the changes in the climate that is caused mainly by human activities, for example the activity of burning fossil fuels, more than changes that are caused naturally by the Earth itself. Therefore the term climate change is being given the same meaning as anthropogenic global warming.

Observed Changes in the Climate System

By observing the climate system it has become very strong and clear that changes in the climate are taking place, and our climate system is getting warmer as time goes by. Changes in the climate from the last 60 years have never been experienced by the population.

These changes include changes such as the atmosphere and the ocean becoming warmer, decreasing amounts of snow and ice, increase in the sea level and increase in the levels of greenhouse gases.

• Atmosphere:

The last thirty years have been warmer at the Earth’s surface than the previous years since 1850. Case in point, it was reported that in the Northern Hemisphere the last 30 years (1983-2012) were the warmest in the past 1400 years.

• Ocean:

Energy storing in the climate system is mostly due to the activity of ocean warming, as it was reported that ocean warming accounted for more than 90% of the energy that was accumulated between 1971 and 2010. The upper ocean (0-700 m) is known that it has warmed in the period between 1971 and 2010, but it most likely warmed between the 1870s and 1971.

• Cryosphere:

For the past twenty years, the area of the earth surface ...

Every one of us can make his own contribution to make a difference. Steps could be taken at home, at the office, on the road and anywhere else to reduce the emissions of greenhouse gas and any risks made to the climate as much as possible. By taking these steps, you would not only be helping the climate but they can also save you money and improve your health, for example decreasing the use of your car for short distances and instead going by foot. One can also take part in any programmes that are offered on a local or state level to support energy efficiency, or take part in clean energy programs or other climate programmes.
