  1. 1NASA reported that the amount of permanent ice (permafrost) decreased by [blank_start]14%[blank_end] between 2004 and 2005. [blank_start]80%[blank_end] of sunlight used to be reflected from the polar ice caps. Now there is less ice the amount of open ocean has [blank_start]increased[blank_end]. since water is darker than ice it absorbs more energy than ice ( Ice reflects [blank_start]85%[blank_end] of light where as water only reflects [blank_start]7%[blank_end]) and converts it to heat speeding up global warming. This process is names the positive [blank_start]albedo[blank_end] effect.
