Climate Alarmists Foiled: No U.S. Warming Since 2005

By James Taylor

When American climate alarmists claim to have witnessed the effects of global warming, they must be referring to a time beyond 14 years ago. That is because there has been no warming in the United States since at least 2005, according to updated data from the National Oceanic and Atmospheric Administration (NOAA).

In January 2005, NOAA began recording temperatures at its newly built U.S. Climate Reference Network (USCRN). USCRN includes 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states. NOAA selected locations that were far away from urban and land-development impacts that might artificially taint temperature readings.

Prior to the USCRN going online, alarmists and skeptics sparred over the accuracy of reported temperature data. With most preexisting temperature stations located in or near urban settings that are subject to false temperature signals and create their own microclimates that change over time, government officials performed many often-controversial adjustments to the raw temperature data. Skeptics of an asserted climate crisis pointed out that most of the reported warming in the United States was non-existent in the raw temperature data, but was added to the record by government officials.

The USCRN has eliminated the need to rely on, and adjust the data from, outdated temperature stations. Strikingly, as shown in the graph below, USCRN temperature stations show no warming since 2005 when the network went online. If anything, U.S. temperatures are now slightly cooler than they were 14 years ago.

Temperature readings from 2005 (far left) to the present (far right) show absolutely no warming.

Climate activists frequently visit or mention particular regions, states, or places in the United States and claim warming impacts are evident, accelerating, and unmistakable. Yet how can that be when there has been no warming in the United States since at least 2005?

Unfortunately, when politicians and climate activists claim they can see the impacts of climate change in a particular place, the media rarely question them on it and tend to accept the claims at face value. But the objective temperature data show no recent warming has occurred.

There is also good reason to believe U.S. temperatures have not warmed at all since the 1930s. Raw temperature readings at the preexisting stations indicate temperatures are the same now as 80 years ago. All of the asserted U.S. warming since 1930 is the product of the controversial adjustments made to the raw data. Skeptics point out that as the American population has grown, so has the artificial warming signal generated by growing cities, more asphalt, more automobiles, and more machinery.

If anything, the raw temperature readings should be adjusted downward today relative to past temperatures (or past temperatures adjusted upward in comparison to present temperatures) rather than the other way around. If raw temperature readings are the same today as they were 80 years ago, when there were fewer artificial factors spuriously raising temperature readings, then U.S. temperatures today may actually be cooler than they were in the early 20th century.

The lack of warming in the United States during the past 14 years is not too different from satellite-measured global trends. Globally, satellite instruments report temperatures have risen merely 0.15 degrees Celsius since 2005, which is less than half the pace predicted by the United Nations Intergovernmental Panel on Climate Change climate models.

Climate crisis advocates attempt to dismiss the minor satellite-measured warming by utilizing ground temperature stations around the globe, which tend to have even more corrupting biases and problems than the old U.S. stations. Of course, they adjust those readings, as well. Perhaps the time has come for American officials to direct some of the billions of dollars spent each year on climate-research and climate-change programs to building and maintaining a global Climate Reference Network.

Either way, it is becoming increasingly difficult for American politicians and climate activists to say they can see the effects of warming temperatures in the United States. For at least the past 14 years, there have been no such warming temperatures.

Alaska Winter Storm Warning

Remember, Last month was the hottest July ever recorded in Alaska?

Alaska Winter Storm Warning
National Weather Service Fairbanks AK
Aug 20 2019

Northeastern Brooks Range above 2000 feet-Including Anaktuvuk Pass, Atigun Pass, Galbraith Lake, Sagwon, and Franklin Bluffs


Heavy wet snow expected. Plan on difficult travel conditions. Total snow accumulations of 4 to 6 inches expected.

Snow will develop this morning, then become heavy this afternoon through late tonight. Snow will taper off Wednesday morning.

Significant reductions in visibility at times. Below 2000 feet, only 1 to 2 inches of snow expected.

I guess that August will not be the hottest month ever in Alaska.

Hottest Month in California? (Updated)



Melrose Colorado Climate Reference Network Station

We have heard it on the progressive news, July was the hottest month on record according to NOAA. In the August issue of Comstock’ Magazine, an author declares July 2017 the hottest month on record. All this hottest ever raised some question, what was the hottest month in California? Previous analysis had indicated maximum summer temperatures were declining details HERE.

One of the issues is how was the hottest month measured; there are several options. Option one is the existing network of weather stations. Option two is satellites, and option three is the Climate Reference Network (CRN).  The Surface Stations project found over 90% of long term stations had siting issues that would produce a warm bias of >= 1C. UHI was a significant factor.

The CRN was established in 2004 to counter the urban heat island influence that was distorting temperatures of the existing networks of weather stations. The hottest temperature reported in the news is the product of the current system, not satellites or the CRN.

What does the CRN have to say about the hottest month? The CRN network has 143 stations in the United States, seven of them in California, all located in remote areas well away for urban influences.

  • Redding
  • Bodega Bay
  • Merced
  • Santa Barbara
  • Yosemite
  • Fallbrook
  • Stovepipe Wells

As you can see from the graphics the CRN stations did not have the hottest July in 2019.  The hottest July was scattered all across the period from 2004 to 2019. When was the hottest CA CRN maximum:

Screen Shot 2019-08-17 at 4.26.36 PM

As you can see the CRN Hottest Months are all over the state and different times of the year.  And, when we look at the satellite temperature we can see that July was not the warmest month.  According to Dr. Roy Spencer, “July 2019 was probably the 4th warmest of the last 41 years.”  Details HERE.

So, when you here the lamestream press touting the warmest or hottest month of the year, you might want to be cautious, as the progressive press maybe just advancing an agenda and not reporting the facts.

July 2019 – Hottest July Ever?

News Brief by Kip Hansen

featured_image_hottest_JulyThe press is again awash with the latest hysterical news that July 2019 was the hottest July ever!

NOAA Data Confirms July Was Hottest Month Ever Recorded

by Henry Fountain  appeared in the NY Times’ barely credible feature Climate Fwd:. The piece was prompted by a NOAA Press release:

July 2019 was hottest month on record for the planet

NOAA has spent billions of tax payers dollars to send up satellites to monitor the weather and thus climate of the Earth.  It pays two different scientific groups, UAH and RSS to produce global temperature data sets of the Earth’s atmosphere, but routinely ignores them when is needs to push Climate Catastrophism.

Those who choose to read a full, scientific explanation as to why July 2019 was NOT the hottest ever should refer back to Dr. Roy Spencer’s piece on this site published on 2 August, July 2019 Was Not the Warmest on Record.

For those who are visual learners, I offer graphs of the two satellite based global temperature records that NOAA ignores when making “hottest ever” declarations, first the graphs from Remote Sensing Systems:



It is interesting to note how different the visual impression is between the most recent data and the longer term data.  In the top image of “recent” data, the trend line from the full dataset is included — it is not the trend of the recent data.  Nonetheless, it is obvious that the data is functionally flat (or even downtrending if one wishes to start at the 2016 peak).

And as a reminder for those who may have forgotten the changes RSS made to it calculations in 2016, from Climate4you:


And from The National Space Science & Technology Center at The University of Alabama in Huntsville, the data set usually referred to as UAH,  two visualizations, same data:



troposphereJust so we know what we are talking about, the Lower Troposphere is the part of the atmosphere in which most of us live.   This little image, from UCAR, helps a bit.  Earth’s tallest mountains are at almost 30,000 feet, just under the 10 km top of the troposphere.  The tops of Tropical Thunderstorms can reach as high as 12.5 km.  Down in the lower troposphere, we have everyday weather events, ground level temperatures, the winds that stir the trees and other weather and climate phenomena experienced by most humans.  Those of your who climb or hike the high peaks of the Sierras in California, as I have,  have gone up out the top of the LowerTroposphere, the same with the highest peaks of the Rocky Mountains.

The Importance of the CRN and What is it Telling Us?

Joseph D’Aleo, CCM

[Note some links were broken at Weatherbell]

The U.S. Climate Reference Network (USCRN) is a systematic and sustained network of climate monitoring stations with sites across the conterminous U.S., Alaska, and Hawaii. These stations use high-quality instruments to measure temperature, precipitation, wind speed, soil conditions, and more. Information is available on what is measured and the USCRN station instruments.

The vision of the USCRN program is to provide a continuous (more accurate) series of climate observations for monitoring trends in the nation’s climate and supporting climate-impact research.

The Surface Stations project found over 90% of long term stations had siting issues that would produce a warm bias of >= 1C. UHI was also a factor.

USHCN surveyed 7-14-09 Enlarged.

According to GAO’s survey of weather forecast offices, about 42 percent of the active stations in 2010 did not meet one or more of the siting standards and were especially egregious and required changes. They did not consider UHI.




Update: HERE is a link to a larger graphic is the Long Study.

The CRN was established based on the work of John Christy. Tom Karl tried to get funding for a complete network but was told by NOAA, the satellites were the future and they refused to fund the complete replacement though some additions were made. The current network has 137 stations (up from 114). By definition they provide proper siting and are not UHI contaminated.

Here is the CRN network today:


Here is a plot of monthly average anomalies since 2004 in CRN. Hmmm.


Hat Tip to Weatherbell.
