Effect of Climate Change

Climate change simply describes the different variations in the Earth’s collective, global climate or in regional climates over a longer period of time.

This essentially refers to the average state of the atmosphere that is present in a particular time scale. It either ranges from decades to millions of years and can be influenced by a number of environmental factors. The Earth can influence it by something as big as sunlight intensity or as non-conventional as human activities.

Recently, it has been surveyed that modern climate changes have been attributed to human action 90-95% of the time. There is also a particular type of "anthropogenic climate change" that is happening and in some areas, it is believed to be global warming

The overall climate change affects the different variations that are present in the Earth’s atmosphere. There are different processes that occur outside the control of man such as the turning of the oceans and the melting of the ice caps.

These various occurrences are sometimes affected immensely by human activity. Because of this, the external processes such as solar radiation, contribute greatly to the current state of the climate of the Earth.

Climate is fairly predictable as it is one of the constants found in a region of a place. The measurement of climate includes knowing the average temperature, the amount of rain that fall.

There are different changes in the Earth’s environment that directly affects the climate. Here are some examples of those changes.

Glaciation

Glaciers are acknowledged as one of the most sensitive indicators of climate change.

They grow and collapse during the lifetime but because of the global warming that is present in the Earth today, glaciers have been unable to regenerate themselves after they’ve lost so much ice during the summer months.

Ocean variability

Climate change can also come from the interaction of the atmosphere and the different oceans. There are various climate changes such as the El Niño Southern oscillation.

This particular ocean variability means that the heat that is stored in oceans moves between the different reservoirs. Because of this the temperature and the climate of a particular once-thriving area may change for the worst.

The memory of climate

Another factor that affects climate change is the memory of a particular climate or "hysteresis". This simply refers to the climate and how it essentially got there.

If there is a decade of drought in one region which have caused lakes to dry up, then it would follow that less rainfall would happen in the future for that particular area since it had been used to dry conditions all along.
