Carbon dioxide Carbon dioxide is a colorless, neutral gas produced by burning carbon and organic mix and by respiration. It is naturally present in air and is absorbed by plants in plants. Carbon dioxide is released into the atmosphere by the burning of solid waste, wood and wood products, and fossil fuels. oil, natural gas, and coal.
Temperate changes The temperatures change naturally over the past 50 years the average global temperature has increased at the fastest rate in recorded history. And experts think the movement is increasing the 10 hottest years on record have all occurred since 1990. Scientists say that unless we control global warming problem.
Water level rising The world will get hotter and hotter snow in the Antarctica will melt and the water will go to the sea and sea level will rise and all of us will drown and most animals that live on ice will die like the polar bear, the animals wont find ice to hunt and live on and now there are not a lot left the ice in the Antarctica is melting faster then expected.
Many things cause global Warming. The causes are split up into two groups, man-made or environmental pollutions causes, and natural causes. Man-made Causes Pollution is one of the biggest man-made problems. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2.
global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as it radiates back into space. As the greenhouse gases build up in the atmosphere the Earth gets hotter
