Filed under: 1.Introduction for Global Warming
Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century and it’s projected continuation.
The average global air temperature near the Earth’s surface has increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005.
Global Warming is something that has been happening for a long time. The temperature of the earth has been increasing more or less continuously since the time of the cave man. Approximately 18,000 years ago the earth began a gradual process of warming up after more than 100,000 years of Ice Ages. Much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.
Since the end of the Ice Age, Earth’s temperature has risen approximately 16 degrees F and sea levels have risen a total of 300 feet! Forests have returned where once there was only ice.
Technically, we are in an “interglacial phase,” or between ice ages. The question is not really if an ice age will return, but when.
If Global Warming stops, then you can start worrying! It means our warm interglacial phase is over and we may be heading into another Ice Age! Therefore we as earthlings should do our part and help prevent our mother Earth from dying. You should have already feel the urgency to save our once beautiful and pure Earth. Global Warming is not something that will affect the future generations but us. Do not give our Earth away!
