Warming effect of greenhouse gases 'has been overestimated': Ice samples suggest pre-industrial air pollution was WORSE than we thought and future temperatures will rise more slowly
Experts analysed soot levels in 14 ice cores from Antarctica dating back to 1750
They found that pre-industrial soot levels were four times higher than expected
Soot has an atmospheric cooling effect, in opposition to greenhouse gases
Climate models must account for both to understand past temperature changes
That soot levels were higher that thought means that modelling is likely off
While the planet is still warming, it is likely not doing so slower than we thought

Antarctic ice has revealed that pre-industrial air pollution was worse than thought, suggesting climate models have overstated the warming from greenhouse gases.
