NOAA shows about 2.5 degrees of warming in US maximum temperatures over the past 50 years

Climate at a Glance | National Time Series | National Centers for Environmental Information (NCEI)

This increase doesn’t exist in the measured daily or equivalent raw monthly NOAA data sets.

The TOB adjustment adds about half a degree warming over the past 50 years


The final adjustment adds another 1.5 degrees warming since the 1970s


About half of the data used in the final adjustment is now fabricated, i.e from a computer model rather than a thermometer.

The real (i.e. from thermometers) component of the final adjusted data set shows about one degree warming since the 1970s

But the fabricated component of the final adjusted data set shows about four degrees warming

Most of the warming over the past 50 years is due to fabricated data, not adjustments

Since 1970, the measured thermometer data shows almost no warming.

The measured adjusted data is warming at about two degrees per century

But the fabricated data is warming at eight degrees per century. Note the big jump after 1995.


The majority of warming over the past 50 years being reported by NOAA is due to fake data.

The NCDC data shows the same big jump after 1995, which exists only in the fabricated data.
