NOAA says that the US has warmed two degrees since the 1890’s.
Yet, in 1989. they said that there was zero warming over the last century.
In 1999, Hansen said there was no US warming over the last 50 years.
in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country
Since 1999, US temperatures have declined. So the trends are – zero from 1889 to 1999, zero from 1949 to 1999, and negative from 1999 to 2013.
Somehow this adds up to +2, in the world of climate science corruption.
