We find changes in background conditions that are opposite to those expected from greenhouse gas forcing in climate models and opposite to what is expected if changes in the background state are mediating more frequent occurrences of CP El Niños. A plausible interpretation of these results is that the character of El Niño over the past 31 years has varied naturally and that these variations projected onto changes in the background state because of the asymmetric spatial structures of CP and EP El Niños.
Disrupting the Borg is expensive and time consuming!

Neither do I.
Well I do because increased CO2 is good for the biosphere.
Agreed, but it is increasing and therefore not a concern.
