Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to a solid known as 'dry ice' which is used as a substitute for normal ice as it is a lot colder and doesn't melt.

Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putti

Global warming is more serious in areas of Alaska, Canada and Northern Eurasia where temperatures have risen by as much as 10 degrees F over the last 35 years. Global warming causes many environmental problems. By raising the world's temperatures, sea levels rise, mountain glaciers recede and snow cover decreases. 1100 square miles of Antarctic ice shelves have broken up in the last year and the rest of the massive shelves are in full retreat. Spring has started to arrive earlier in Europe and autumn later. 1998 was the warmest year in recorded history in the USA. In the summer of 1998 over 130 people were killed by the extremely hot humid days. Many similar trends were reported around the world. Temperatures like these are predicted to become more frequent in the next 50 years.

The amount of CO2 in a planet's atmosphere affects the temperature of the planet. As more and more CO2 builds up in the atmosphere, less heat can escape and the planet gets hotter. The CO2 traps radiation from the sun like a greenhouse. This is called global warming or
