What is climate?
The condition of earth's atmosphere over a long period of time.
How do scientists define 'climate change'?
The effects of Earth's increasing global temperature.
Certain gases that let the sun's rays in but doesn't let the heat out.
What are greenhouse gases?
Most air pollutants are the result of this.
What is the burning of fossil fuels?
What are FOUR sources scientist use to collect paleoclimate data?
1. Fossils
2. Rocks

Current carbon dioxide levels in the atmosphere may be higher than they have been in the past how many years?
2 - 3 million years
