An international team of researchers suggest that future global warming may eventually be twice as warm as projected by climate models Global warming could be much worse than predicated by current climate models. Researchers often use records of Earth’s past to predict changes in the future. A latest assessment of past warm periods shows that future global warming may be twice as warm as projected by climate models and sea levels may rise six meters or more with 2°C of warming. A world that heats up by 2C is regarded as the limit for a climate-safe planet and 2015 Paris Climate Agreement aims to hold average global warming well below 2°C by reducing carbon emissions. “Observations of past warming periods suggest that a number of amplifying mechanisms, which are poorly represented in climate models, increase long-term warming beyond climate model projections,” said lead author Prof Hubertus Fischer from University […]
