Some very short climate-related animations

Here's a compilation of short animations on climate science and climate change:

• Richard Alley's Milankovich dance, explaining the ice ages, CO2 and global warming (5 min.)
• 130 years of historical global temperature change (1880-2011, NASA); 26 seconds 
• Arctic sea ice retreat, 1980-2007, about 30 seconds 
• “Time history of atmospheric CO2?;  shows the earth “breathing” over 800 thousand years; about 3 minutes 
• Trend and Variation; “Human walking an active dog on leash” metaphor for signal vs. noise in climate change (“We’re looking at the dog, but we should be concentrating on the owner…”); about 1 minute
• It’s All About Carbon; a series of roughly 3-minute cartoon shorts from PBS, explaining greenhouse gas science.  (But as I recall, the "personal action" ending could have used refurbishing: it needs the POW pledge.)
