Albedo

Yo you guys cant use wikipedia as a source

Albedo is the ability of an object to reflect light from the sun. Possible values 0 (dark) to 1(light) (1) The albedo of the earth is .367 (2)

mean annual winter albedo (3)

mean annual summer albedo (3)

Ice has much more albedo than land and water. So as the climate warms, and the ice melts, there is less ice to reflect the sun's rays. So more rays get trapped, making the climate even warmer, and speeding up the process.

The **Keeling Curve** is a graph showing the variation in concentration of atmospheric carbon dioxide since 1958. It is based on continuous measurements taken at the Mauna Loa Observatory in Hawaii under the supervision of Charles David Keeling. . Keeling's measurements showed the first significant evidence of rapidly increasing carbon dioxide levels in the atmosphere. Many scientists credit Keeling's graph with first bringing the world's attention to the effects that human activity were having on the Earth's atmosphere and climate.[|[1]]

A description/explanation of your topic A description of the history of the science behind your topic -For example, how do we know so much about the keeling curve? Where did it come from? Who discorved it? Etc. A description of how it relates to climate change At least one relevant diagram (can be taken from other site)
