Carbon isotopes do not show that humans’ climate impacts are too small to notice, despite the Daily Sceptic’s inaccurate claim

Human-caused carbon emissions’ effect on climate is ‘non-discernible’. Measurements of carbon isotope ratios in atmospheric CO2 indicate that it is the recent expansion of a more productive biosphere that has led to increased CO2 concentrations in the atmosphere.
