Climate: most fossil fuel reserves should remain underground

Half of conventional oil resources, the majority of natural gas resources and almost all coal resources should remain underground if humanity is to succeed in limiting global warming to 2 ° C, CO2 capture and storage included. Almost all non-conventional hydrocarbons – including shale gas – should remain untapped, according to the analysis of two researchers from University College London published in the journal Nature on January 8, 2015.
