The mean albedo for the l-year period was 0.32. The Tiros VI1 data are in general agreement with the values of albedo deduced from the emissivity sensors of the first ... WebOverall, Earth's average albedo is about 31%. Brightness of the Sun. The brightness of the Sun can change in small amounts over years to centuries and can change large amounts over millions to billions of years. The Sun has become less bright since 1900, according to NASA. These are only two of the factors that impact climate.
