You may have to stand back from your monitor screen to fully appreciate the layout design of the information, but Stanley Kay's information-rich data visualization wonderfully communicates the relative size of each of the world's nation's carbon emissions:
Here's Stanford Kay's description of his infographic:
Originally conceived as one of my Myth Buster information graphics for Newsweek's International Edition, a piece on global carbon emissions showing both national and per capita data has found a home in the April issue of the Atlantic Monthly. The image of a footprint is composed of circles sized relative to the carbon emissions of each nation and color coded according to region. In the final version of this information graphic there will be a second footprint of per capita emissions by nations. That will be a very different picture. The leader in per capita emissions is Gibraltar followed by the Virgin Islands. The U.S. drops down to number twelve and China falls way down the list due to its large population. It appears that countries that don't grow or produce much have the largest footprint because they have to import almost everything they need.
Welcome to the blogosphere's toolchest! Here, unlike other blogs dedicated to analyzing current events, we create easy-to-use, simple tools to do the math related to them so you can get in on the action too!

Political Calculations' U.S. GDP Temperature Gauge provides a means to quickly evaluate the growth rate of the U.S. economy against the backdrop of how the economy has performed since 1980, with the "temperature" color spectrum ranging from a recessionary "cold" (purple) through an expansionary "hot" (red).
The GDP Temperature Gauge presents both the annualized GDP growth rate as reported by the U.S. Bureau of Economic Analysis reports for a one-quarter period and also as averaged over a two quarter period, which smooths out the volatility seen in the one-quarter data and provides a better indication of the relative strength of the U.S. economy over time.
Recession Probability Track
Political Calculations' Recession Probability Track shows the probability that the U.S. economy will be in recession 12 months from the indicated date (shown in red) while revealing the probability trend over the past four years.
Previously, the probability of recession peaked at 50% on 4 April 2007, which means that March-April 2008 was the most likely period in which the NBER would have found the U.S. to be in recession.
As it happens, they almost did. The NBER instead chose December 2007 as the beginning month of the most recent recession (we had found a 46% probability for a recession beginning in that month!)
The Recession Probability Track ceased to be a leading indicator of recession in the U.S. following the Federal Reserve's adoption of its current Zero Interest Rate Policy, where the Fed artificially constrains short term U.S. Treasury yields near zero percent.
We continue to post the Recession Probability Track to monitor the yield on the 10 Year Constant Maturity Treasury, where a falling value provides a leading indication of a worsening economy.
