They estimated that water vapor accounts for about 50% of Earth's greenhouse effect, with clouds contributing 25%, carbon dioxide 20%, and the minor greenhouse gases and aerosols accounting for the remaining 5%. In the study, the reference model atmosphere is for 1980 conditions.

Don Messick originated the voice of Scooby-Doo, and was the voice of the character for over 25 years until his retirement from voice acting in 1996 (he subsequently passed away the following year).rank Welker's Scooby-Doo voice is pretty much identical to the voice he used for Brain on Inspector Gadget.. Hadley Kay and Neil Fanning are the worst, IMO...
