Document Summary
Co2 is a greenhouse gas change concentrations and you can take temperature. Weather over a long period of time. *climate change - a change in global or regional climate patterns, attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. A change in the statistical distribution of weather, on time scales that are greater than 10 years. *champsosaur - reptile, freshwater fish eater, related to crocodile. Uw - madison geosci 100 lab: the climate system. White ice reflects more of the sun"s energy back into space than does dark water: the energy that drives our climate system ultimately comes from the sun. This sunlight is dominantly in the visible wavelength (we can see it!). Is this visible energy more or less energetic than x-ray energy : after the earth absorbs this visible light, it transforms the visible energy to another wavelength (or color of light).
