A new study exposes the uncertainty in solar activity reconstructions, but suggests solar models explain climate changes far better than atmospheric CO2 concentrations. Proxy model estimates of the impact of solar variability on climate are highly uncertain. For example, estimations of the increase in solar irradiance over the last 400 years range anywhere from 0.75 … Continue reading Solar Variability Linked To Climate Change…CO2 Not ‘The Primary Driver For Nearly All Of Earth’s History’
