Three-quarters of known fossil fuel reserves must be kept in the ground if humanity is to avoid the worst effects of climate change, a group of leading scientists and economists have said in a statement timed to coincide with Earth Day.
The Earth League, which includes Nicholas Stern, the author of several influential reports on the economics of climate change; Hans Joachim Schellnhuber, a climate scientist and adviser to Angela Merkel; and the US economist Jeffrey Sachs, urged world leaders to follow up on their commitments to avoid dangerous global warming.
