Multiple independent analyses of long - term temperature records show average global temperatures rising as greenhouse gas concentrations have risen.

This finding, though based on uncertain reconstructions of past ENSO behaviour, is entirely independent of previous analyses confined to the restricted instrumental climate record...... such a trend would seem consistent with the response to the general increase in explosive volcanism during the fifteenth — nineteenth centuries in conjunction with reduced solar irradiance that is responsible for the millennial cooling trend of Northern Hemisphere mean temperature before modern anthropogenic warming.
