We don't own this earth it owns us! What are we doing? How can we be so lazy?
- The change in land masses and the constant moving of these land masses affects ocean currents and wind which in turn affects climate in different areas around the world.
- The tilt of the Earth is another factor, although widely thought the Earth's tilt is unchanging it is said that the angle of the tilt changes by little more than half a degree each century, this change is called precession. In the time of the Egyptians when the pyramids were built (around 2500BC) the pole was near the star Alpha Draconis rather than Polaris (the Pole Star). Precession affects seasons and climate, more tilt means colder winters and warmer summers, less tilt means milder winters and cooler summers.
- The vast stretches of open water that cover 71% of the earths surface also have an effect on the climate. Ocean phenomenon such as the Pacific Ocean's El NiƱo, which is a change in the temperature of surface water in the tropical Eastern Pacific, can affect climate and weather worldwide for a period of time afterwards.
- Through our growing numbers, demand and greed we are taking more and more from the enviroment and putting less back. Humans have been affecting the build up of green house gases such as carbon dioxide since we began, cutting down trees reducing the amount of plant-life breathing in the carbon dioxide. Since the end of the 19th century (the industrial revolution) we have been increasing the amount of CO2 in the air through the invention of the motor engine and increase in burning of fossil fuels, on top of that cutting down frightening numbers of trees, this is now having an effect are we too greedy to care?
- Methane levels have over doubled since the industrial revolution, this is caused by livestock and Paddy feilds.
- We are also affecting something underground we cannot see happening, this is called permafrost. Permafrost is a solid structure extending as far down as 2,000 feet in some areas, it is made from frozen soil filled with roots, sticks, plants many of these said to date back as much as 30,000 years. Permafrost holds about 14% of the worlds carbon and if this starts to melt the carbon will be released but also the ground will become soft causing havoc to anything built above these areas found in Alaska, Canada, Siberia and Scandanavia.
