Global Temperature Rises Could Be Double Those Predicted by Climate Modeling

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 meters or more even if the world does meet the 2 degree target of the Paris accord.

The findings, published last week in Nature Geoscience, were based on observations of evidence from three warm periods in the past 3.5m years in which global temperatures were 0.5-2 degrees above the pre-industrial temperatures of the 19th century.

The researchers say they increase the urgency with which countries need to address their emissions.
