TEDxPSU: Dr. Michael Mann - A Look Into Our Climate: Past To Present To Future

TEDx events are independently organized TED events that follow the general TED format, but are organized locally. I came across Dr. Michael Mann's presentation at TEDxPSU on twitter (follow him: @MichaelEMann). Dr. Mann is known for his extensive research in paleoclimatology- including the Hockey Stick Graph that displays recent, rapid global warming.

ESRI Map of Carbon Dioxide Emissions

ESRI has produced a map that displays carbon dioxide emissions from 1960 to 2008. The map is dynamic in that it allows the user to pick the year, or consecutive years, to display in addition to having the ability to "play" the map as an animated timeline. Another cool feature of the map is that it has two sets of symbology; the map displays countries' total emissions as a color and relative emissions are represented by dots. For more information, including how the map was made, visit ESRI's Map Story Profile.
