A groundbreaking new study is confirming what green campaigners have long argued: in order to stave off climate disaster, the majority of fossil fuel deposits around the world—including 92 percent of U.S. coal, all Arctic oil and gas, and a majority of Canadian tar sands—must stay “in the ground.”
The research is a boost to world-wide green campaigns, from the bid to stop the Keystone XL pipeline to grassroots protest against Arctic drilling.
The new findings were published in the journal Nature and authored by Christophe McGlade and Paul Ekins, both of whom hail from the University College London.
They write, “Policy makers have generally agreed that the average global temperature rise caused by greenhouse gas emissions should not exceed 2 °C above the average global temperature of pre-industrial times.”
The researchers explain that they employed a “single integrated assessment model that contains estimates of the quantities, locations and nature of the world’s oil, gas and coal reserves and resources” to determine what it would take to stay below this limit.

“Our results suggest that, globally, a third of oil reserves, half of gas reserves and over 80 per cent of current coal reserves should remain unused from 2010 to 2050 in order to meet the target of 2 °C,” the researchers explain.
