USGS: natural resources in the Arctic -- HUGE

This is the headline:

US Geological Survey assessment finds Artic (sic) oil, natural gas resource potential is immense.

I'm glad to see I'm not the only one who makes typographical errors.

From the story:

According to an assessment conducted by the U.S. Geological Survey (USGS), the Arctic holds an estimated 13 percent (90 billion barrels) of the world's undiscovered conventional oil resources and 30 percent of its undiscovered conventional natural gas resources. While risks associated with economics, the region's harsh environment, and ongoing territorial disputes are considerable, potential rewards are immense.
