Temperatures warmed from 1890 to 1940. (1890 was the lowest ENSO on record.) They cooled from 1940 to 1975. They warmed from 1975 to 1998. (1998 was the highest ENSO on record.) They have cooled since 1998.
Does anyone doubt that El Nino years are warm, and La Nina years are cold? Hansen prays every night to Gaia for an El Nino. Climate science is dominated by complete morons.
