Coal is the dirtiest fossil fuel and has contributed more to global warming than either oil or gas. By one estimate, 46% of all manmade greenhouse gases spewed into the atmosphere since 1750 have come from coal, raising seas that threaten major cities and supercharging hurricanes. The world has responded.

Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).
