Ghostbusting Temperatures

A search in temperature databases show no warming during the 20^th century - and temperatures since the 1950s have been falling over most parts of the U.S.A. So, where's the warming? At least not in the United States.

In a previous article – Ghost Temperatures - we expressed our serious doubts about the way average global temperatures are processed in order to arrive to the claimed “global warming”. Examining the U.S. Historical Climatology Network database, with records dating back to the early part of the 1800s, we have found no reason to claim there has been a warming in the United States.

Scientists at the Center for the Study of Carbon Dioxide and Global Change, insist that there has not been any substantial warming during the 20th century, and they claim that "The Global Surface Air Temperature Record Must Be Wrong". Dr. Sherwood. B. Idso, and his sons Drs. Craig and Keith Idso, have reviewed a large body of evidence that suggests that the highly-hyped "unprecedented global warming" of the past two decades never actually occurred.

According to what they say in their excellent website, “This evidence includes:

1. The satellite microwave-sounding-unit temperature record, which in the absence of the massive 1998 El Niño heat pulse shows no warming whatsoever from 1979 to the present,



2. The weather-balloon temperature record, which for the same circumstances also shows no warming,



3. The surface- and satellite-derived temperature records of earth's polar regions, which also show no warming, and



4. the high-quality U.S. Historical Climatology Network data base, which, not surprisingly, also shows no statistically significant warming over this period.”

They now augment this substantial body of empirical evidence for no global warming over the last two decades with observations gleaned from tree-ring reconstructions of surface air temperature. We encourage you to visit their website and learn why they are so sure about what they claim.

But our main goal is providing here with a graphical view of the temperatures in the United States of America, using data from the U.S. Historical Climatology Network data base, plotting the data since the year 1900 (other records start later, as 1920, or 1920, but these are the exception), and grouping them in different pages – one for each of the contiguous states – where the different trends have been calculated.

The source of data is here: http://www.co2science.org/ushcn/ushcn.htm in case someone wants to plot his own trends starting and ending in different dates.

After a long and hard work we finished plotting the trends and making the graphs. We hope they will prove useful for having a better and clearer idea of what temperature trends really are. Comparing them whith those from the IPCC. and its cohort of alarmists should alleviate your fears of a "global" warming of catastrophic consequences.
