Sorry for not providing the citation right away. Here's the evidence (with discussion and links to source studies) for trillions of tons of coal in Alaska: http://www.groundtruthtrekking.org/Issues/AlaskaCoal/HowMuchCoal.html http://www.groundtruthtrekking.org/Issues/AlaskaCoal/HowMuch... In particular, it links to this 2005 USGS study: https://pubs.usgs.gov/dds/dds-077/ https://pubs.usgs.gov/dds/dds-077/ > "The combined measured, indicated, inferred, and hypothetical coal resources in the three areas are estimated to be 5,526 billion short tons (5,012 billion metric tons), which constitutes about 87 percent of Alaska’s coal" The amount of fossil fuel energy in the ground (if we're very clever about extracting it) is absolutely vast. Enough to provide current needs for hundreds or even thousands of years, but to cook the climate and chemically change the atmosphere to that of a stuffy room long before that.
