Ron Clutz writes at "Science Matters": " TTLs (lower troposphere temperatures) include mixing above the oceans and probably some influence from nearby more volatile land temps, They started their recent cooling later that SSTs from HadSST3 but are now showing the same pattern. It seems obvious that despite the three El Ninos, their warming has not persisted, and without them it would probably have cooled since 1995. Of source, the future has not yet been written."
