Global Warming

Global warming is the gradual increase of the earth’s atmosphere resulting in an ever increasing temperature of the earth and the melting of polar land. Human population has a huge effect on global warming but human power can also determine quite dramatically how bad global warming will develop. This can affect the lives of many organisms and affect their habitat – consequently extinction occurs.

How does global warming happen and what causes it?

Global warming is the process of when solar radiation from the sun makes its way towards earth and heats it up. Half of the radiation is absorbed by the earth and the other half roughly is reflected back into the atmosphere away from the earth. However, infrared radiation is emitted from the earth; an amount of this is emitted into the atmosphere and never seen again. The other amount of radiation emitted gets trapped within the ozone layer surrounding the earth. The more radiation emitted, the thicker the ozone layer is believed to become, making it harder for the radiation to escape.

What are the signs of global warming?

The ozone layer is physically keeping the heat emitted from the earth in our atmosphere, making the earth continuously hotter. The immediate responses to global warming is the glaciers and ice caps which are all melting more and more by the day. This is polar habitat, and polar bears’ habitat is therefore being destroyed, and will eventually result in extinction of that species if they cannot adapt to a new life. The sea is warming from global warming which spreads throughout seas and is practically hot water contact with ice features, melting them ...
