Major physical processes and events have been happening to the Earth throughout its long history and will keep on happening.
Some physical processes are continuous, taking place over a very long periods of time. Other physical processes take very little time by comparison: we humans have chosen to call some of those "catastrophic events" because they seem to have taken place with hardly any warning.
For the past 4,000 million years the outer crust of the Earth has been changing. Its tectonic plates, continually move around forming continents which then break up and re-form in other configurations. The friction caused by the sliding and subduction of the edges of plates against one another causes mountain chains to be thrown up and fiery volcanoes to spew out new soil and smokey, noxious gases which pollute the atmosphere.
65 million years ago the dinosaurs were wiped out by a major event. It was probably a huge meteorite from outer space which suddenly hit the Earth. The resulting air pollution caused thousands of years of continuing global darkness and bitter cold because heat and light from our Sun could not reach the surface until the pollution was eventually absorbed by the Earth.
An ice sheet on Antarctica began to grow some 20 million years ago. The current ice age, the Pliocene-Quaternary glaciation, started about 2.58 million years ago during the late Pliocene when the spread of ice sheets in the Northern Hemisphere began. Since then, the world has seen cycles of glaciation with ice sheets advancing and retreating on 40,000- and 100,000-year time scales called glacials (glacial advance) and interglacials (glacial retreat).
The Earth is currently in an interglacial, and the last glacial period ended about 10,000 years ago. All that remains of the continental ice sheets are the Greenland ice sheet, the Antarctic ice sheet and smaller glaciers such as on Baffin Island. It is likely that people lived in the temperate zones of the Earth before that last glacial period began, along with other animals and plants. After the maximum had occurred and the glaciers receded, modern humans were able to migrate from a belt of land around the Earth's Equator towards its poles.
Ø The fuel we burn, especially oil and coal, contributes to climate change, which has the potential to destroy our way of life.
Ø Global warming can be the cause of hurricanes, and droughts.
Ø More frequent and powerful cyclones and hurricanes, more frequent and intense floods and droughts are clear indications that climate change has already begun.
Ø global warming is also responsible for causing global glacier decline, sea level rise, scarcity of freshwater resources.
Ø Extreme weathers and weather related events such as flooding, drought, wild fires, heat waves, and tropical cyclones are expected to occur even more frequently and to become even more intense
Ø Extreme and rapid changes in temperature would affect the length of various seasons

Global Warming does not affect the temperature. Global Warming is the temperature -- rising!A:It stipulates that Temperatures will globally increase; unless some Extra Huge volcanic Ash Cloud might Intervene. A:Global warming IS the average temperatures of the world. The temperature is going up. That's what global warming is.
Polar bears are being effected by global warming and lots of other animals but polar bears might be in the worst weather. Just imagine your children might not see a polar bear out of a zoo because of we have killed them off by Global Warming!
because the cray -crayness of it was cool?
it causes it because you have to think why do we have global warming if we didn't have global warming we might not be living right now and i know global warming is bad but if it wasn't for global warming we might not have snow, rain, cold and summer. that's what causes global warming. so I'm telling you this right now we better be thankful we have global warming if not one day we might not have a white Christmas like i wanted one and we haven't had one in a long time...
The consequences might be that we do manage to stop, or at least slow global warming. But if we don't try, then global warming definitely won't stop.
No. While global warming might affect tornado activity, tornadoes themselves are an end product of weather and climatic activity, not a cause.
Global warming would have no affect on the location of the poles.

The country being hot today is weather, not climate. It might have something to do with global warming, but it might not. However, if the weather is always getting hotter, after some years this becomes the climate of a place.

In 30 years, global warming may affect is by changing our climate. This will change many things, such as vegetation and energy. It may also increase skin cancer.
