The Completely Fake Time Of Observation Bias

In 1999, NASA’s James Hansen was concerned that the very high-quality US temperature record didn’t match Hansen’s fake global warming trend.

How can the absence of clear climate change in the United States be reconciled with continued reports of record global temperature? Part of the “answer” is that U.S. climate has been following a different course than global climate, at least so far. Figure 1 compares the temperature history in the U.S. and the world for the past 120 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 …

The Seattle Tacoma Airport Temperature Sensor is Running Too Warm: Again

There appears to be a problem with the temperature sensor at Seattle-Tacoma Airport:  it seems to be running several degrees too warm.

This is not the first time this has happened.   And excessively warm temperatures at airport stations seems to be a growth industry around here.   In a previous blog I talked about the problem at Yakima–which has been fixed.   Ellensburg is running too warm as well.

But this blog will be about Seattle-Tacoma Airport, whose official NWS/FAA temperature sensor is located between two of the runways.

Why should you care about this?
