Global Warming

By Scott






Global Warming started at the end of Pleistocene Ice Age. At this time most of North America, Asia, and Europe were covered in ice. Then the earth started to warm up.
As time goes on from the end of the Ice Age large changes appear. The Bearing Strait became underwater and forests have come where only ice used to be. Observedly, global warming began long before industry and the internal combustion engine.
The earth warms and cools in cycles. The earth’s temperature goes up about every 100,000 years. The warm periods are called interglacial periods. These periods last from 1,500 to 20,000 years. Presently we are on the year 18000. Sometimes there are small periods of warming. Sometimes warming can occur over 40 to 400 years and then cool back down. From year 1000 to 1400 was a warm period that was even hotter than it is now. Then it cooled back down into the small ice age.
If CO2 does cause global warming then human activity and industrial business is a small contributing factor to all of the CO2 in the atmosphere. Every year there are 186 billion tons of CO2 that enter the Earth’s atmosphere. Only 6 billion (3.2%) is from human activity. The rest comes from natural causes such as volcanoes and decaying plants. A 25% increase in human CO2 increases global CO2 by 1%. In addition, CO2 does not stay in the atmosphere forever. It comes down and is recycled.
CO2 is a life giver. It is vital for plant life to survive. The plants take in the CO2 and make food so they can live. The life on earth is carbon based and we need CO2.
Everything in this world falls into place. Cars and industrial businesses emit CO2. Then plants take in the CO2 to make food to survive. The plants then eliminate oxygen, which humans and animals need to survive, as the plants need the CO2. After humans and animals breath in oxygen they breathe out CO2 as a waste product and the cycle keeps going on and on.
