How much have we polluted? is a map visualization of global carbon dioxide emissions.

The map allows the user to view the yearly per capital and total CO2 output of individual countries around the world.

Data behind the map is from 1960 to 2008, which enables the user to see which countries have increased or decreased their CO2 emissions over time.

The map also allows the user to compare two countries at once.

The Significant Earthquake Database, produced by NOAA National Geophysical Data Center, contains information on destructive earthquakes from 2150 B.C. to the present that meet at least one of the following criteria:

  • Moderate damage (+ 1 million dollars)
  • 10 or more deaths
  • Magnitude 7.5 or greater
  • Modified Mercalli X or greater (Wikipedia)
  • Earthquake that generated a tsunami

Users can import the resulting search into an Excel worksheet or download the entire dataset in tab-delimited format.

Natural hazards interactive map (which includes information on tsunamis and volcanoes as well) displays data from the database and can be extracted.
