Global temperature rises could be double those predicted by climate modelling

Researchers say sea levels could also rise by six metres or more even if 2 degree target of Paris accord met

Temperature rises as a result of global warming could eventually be double what has been projected by climate models, according to an international team of researchers from 17 countries.

Sea levels could also rise by six metres or more even if the world does meet the 2 degree target of the Paris accord.
