Document Summary
What the atmosphere is doing over short time scales. What you see when you go outside. The average weather pattern in a region over long periods of time (typically 30 years or more) The influence that humans may have on earth"s climate change. Rate of climate change today is much greater. Nitrogen and oxygen make up over 99% by volume of the entire atmosphere, not counting water vapor. Water in atmosphere can vary greatly depending on location. Has high concentrations of ozone and plays an important role in protecting the surface from the sun"s harmful ultraviolet radiation. Is stratosphere is due to absorption of ultraviolet sunlight by the ozone layer. Most of the sun"s radiation and energy are in the visible region of the electromagnetic spectrum. The percentage of radiation reflected from a surface. Light-colored objects have higher albedo than dark-colored objects. Polar regions of earth have much higher albedo than heavily forested areas near the equator.
