Albedo: The Earth or the Earth's atmosphere reflects 30% of the sunlight that hits it. Therefore the Earth's Albedo is 30%.
Last night I had 3 more hours of Meteorology 111, or Meteorology without math or science as I call it. We had an interesting discussing about measuring temperature using Fahrenheit, Celsius, or Kelvin. When it came time to do some actual conversions, the instructor said "we can either do the math, or press the 'I believe' button. I think I was the only one in class who voted for 'do the math'. Needless to say, I lost. I still learned stuff, and that's the most important part.
