New Research Further Demonstrates Problems with Surface Temperature Records and Models
Climate Change Weekly has long detailed the severe problems with surface temperature records, driven largely by the Urban Heat Island (UHI) effect compromising the integrity of the vast majority of temperature stations.
In two studies for The Heartland Institute, meteorologist Anthony Watts detailed the extent to which the surface station record in the United States is compromised by station siting that violates the National Oceanic and Atmospheric Administration’s (NOAA) own standards for the proper, unbiased, siting of surface stations. Watts’ initial 2009 study found that 89 percent of the surface stations in NOAA’s and the National Weather Service’s (NWS) system were poorly sited and biased. After the study, NOAA/NWS closed some of the most severely compromised, ridiculously sited stations highlighted in report. Indeed, NOAA had already recognized the problem and had prior to the first study’s release established the U.S. Climate Reference Network (USCRN), consisting of 137 climate observing stations with the best equipment, existing in stable locations unlikely to ever be compromised by nearby development. At the same time, however, NOAA also added thousands of previously unregulated stations established and maintained by others to its system.
The larger system provides more comprehensive coverage, but the vast majority of the stations are, unsurprisingly, poorly sited. As a result, Watts’ follow up survey of NOAA’s surface station network found 96 percent of the stations used to determine U.S. average temperatures are biased upward due to poor siting. The UHI has compromised them.
How bad is the problem? As explained in an article in The Epoch Times, the U.S. Environmental Protection Agency has estimated that “daytime temperatures in urban areas are 1–7 degrees Fahrenheit higher than temperatures in outlying areas, and nighttime temperatures are about 2–5 degrees Fahrenheit higher.” Whereas the temperature record from the USCRN indicates little or no temperature change during its 18 years of existence, the broader network supports claims that the U.S. is warming. By the way, as detailed in previous Climate Change Weekly posts, what’s true for the United States is also true for the global surface station network and, since 2015, for the ocean temperature measurement system. Both are biased by poor siting compromising the validity of the temperatures measured.
A new report from the Heritage Foundation by Roy Spencer, Ph.D., a long-time friend of The Heartland Institute, principal research scientist at the University of Alabama in Huntsville, and currently a visiting fellow in The Heritage Foundation’s Center for Energy, Climate, and Environment, looks at a slightly different problem with temperatures: the difference between measured warming and climate model temperature projections. It is not just that the Earth has warmed less than biased temperature measurements indicate, it has also warmed less than climate models have said it should for the amount of CO2 humans have emitted into the atmosphere.
Spencer’s research found recent warming is likely not due solely to human greenhouse gas emissions, and the warming experienced is substantially less than climate models have predicted—43 percent less, in fact. And that’s even when readings from the UHI-biased stations are included.
Spencer examined summertime temperature readings for 12 Corn Belt states in the United States. Each of the 36 models he compared to measured warming by surface stations, weather balloons, and global satellites overstated the amount of warming experienced, with most of the models off by 100 percent or more. (See the graphic, below)
Spencer is also working on a large-scale study to explain the discrepancy between urban and rural temperature stations globally, and how that plays into recent claims temperatures are setting all-time records. His preliminary data suggests measured warming is strongly correlated to population density. As cities grow, and populations increase and become more densely packed, temperatures in urban and suburban areas rise faster than in the surrounding countryside, once again confirming Watts’ conclusion that the temperature record is compromised by UHI.
If Watts’ and Spencer’s research are correct, not only do climate models “run too hot,” as even some of their proponents have been forced to admit, but the regularly reported surface station record is running too hot as well.

Global Hurricane Update: No Detectable Change Despite Warming
New research from Professor Roger Pielke, Jr., Ph.D., of the University of Colorado at Boulder, and research meteorologist Ryan Maue, Ph.D., suggests there may have been a slight upward trend in global landfalling major hurricanes since 1970, but there has been no similar trend in minor landfalling hurricanes.
They throw cold water on the idea major landfalling hurricanes have increased due to global warming by looking at longer-term records and trends.
If one begins the analysis in 1950 rather than 1970, in the Western North Pacific and North Atlantic, where we have reliable longer-term data, one finds no upward trend in either major or minor landfalling hurricanes.
As Pielke, Jr. and Maue remark, their research confirms the findings of NOAA in the United States and the U.N.’s Intergovernmental Panel on Climate Change (IPCC):
In technical terms, detection of change has not been achieved—which is fully consistent with the scientific consensus of NOAA and the IPCC. Without detection there can be no attribution under the IPCC framework for detection and attribution. Given the large interannual and decadal variability in tropical cyclones, data are easily cherrypicked (intentionally or unintentionally) to identify spurious trends.
Looking beyond the number of major, minor, and total hurricanes, Pielke, Jr. and Maue cite the work of Phil Klotzbach, Ph.D., examining hurricane severity over time. Klotzbach’s research on Accumulated Cyclone Energy (ACE), a measurement of annual hurricane frequency, intensity or strength, and longevity, found that as the planet has modestly warmed, there has been no increase in ACE since 1980.

No matter who measures it or what metric is used, there is no evidence climate change is causing more frequent or more powerful hurricanes.

Heartland’s Must-read Climate Sites
Urban Agriculture Produces More Carbon Dioxide than Conventional Agriculture
Whatever the emotional or psychological benefits of growing fruits and vegetables on small plots of land within cities and urban areas, new research indicates the crops grown there produce much more carbon dioxide (CO2) per serving of food than conventional commercial farms.
The study, published in the journal Nature, was produced by an international team of 13 researchers, from universities and research institutes in the United States, Canada, France, Germany, Poland, and the United Kingdom. Led by scientists at the University of Michigan, the study noted urban agriculture is increasing as people embrace growing food locally for a variety of reasons, including the pleasure of growing ones’ own food, the belief that growing crops in urban environment is more sustainable, uses less energy, and produces healthier food. Another reason often cited is the desire to reduce agricultural emissions to fight climate change. I have discussed the fact previously that there is no evidence locally grown food reduces energy use or that the food produced is healthier. This study is the first to laser-focus on the latter justification given for urban agriculture—reducing farming’s carbon footprint—finding that the crops produced on urban farms and gardens produced six times more CO2, on average, than crops from conventional farms, with exceptions for select vegetables.
As described by Phys.org:
The study … used data from 73 urban farms and gardens in five countries and is the largest published study to compare the carbon footprints of urban and conventional agriculture.
Three types of urban agriculture sites were analyzed: urban farms (professionally managed and focused on food production), individual gardens (small plots managed by single gardeners), and collective gardens (communal spaces managed by groups of gardeners).
For each site, the researchers calculated the climate-altering greenhouse gas emissions associated with on-farm materials and activities over the lifetime of the farm … expressed in kilograms of carbon dioxide equivalents per serving of food, were then compared to foods raised by conventional methods.
After accounting for infrastructure, supplies, energy, and water, and the length of continued operations, the research group found that vegetables and fruits produced through urban agriculture emitted 0.42 kilograms of carbon dioxide equivalents per serving on average, six times more than the 0.07 kg CO2e per serving of conventionally grown produce.
“By assessing actual inputs and outputs on urban agriculture sites, we were able to assign climate change impacts to each serving of produce,” said study co-lead author Benjamin Goldstein, assistant professor at the UM School for Environment and Sustainability. “This dataset reveals that urban agriculture has higher carbon emissions per serving of fruit or vegetable than conventional agriculture—with a few exceptions.”

New Deep Sea Coral Reef Surprises Discoverers
Across dozens of articles in recent years, Climate Realism has noted that coral colonies are doing much better than commonly claimed by the mainstream media, which regularly tout corals’ impending demise, purportedly due to human-caused climate change. Among the findings we’ve discussed are posts on research published in Nature showing that billions of previously uncounted corals spanning hundreds of coral colonies have been recently discovered. Another study found coral colonies thriving in waters deeper and cooler than normally expected.
Now, CBS News is reporting that researchers have discovered and mapped in some detail the largest ever deep-sea coral cold-water reef in the world, off the United States’ Eastern Seaboard.
As CBS reported:
It’s been known since the 1960s that there were massive mounds of cold-water coral off the East Coast, and for years, NOAA researchers say they thought their study area, the Blake Plateau, was “sparsely inhabited.” But more than a decade of mapping and exploration “revealed one of the largest deep-sea coral reef habitats found to date anywhere in the world,” NOAA Ocean Exploration operations chief Kasey Cantwell said.
Researchers found the reef system in a study area of the Blake Plateau nearly the size of Florida, ranging roughly from Miami to Charleston, South Carolina. The underwater seascape turned out to be 310 miles long and 68 miles wide, NOAA said, and covers 6.4 million acres, an area larger than Vermont.
The “million mound” area of corals found coral colonies thriving between 656 feet and 3,280 feet below the ocean surface, absent any sunlight in water temperatures of 39℉.
“‘Many [deep-sea corals] live for hundreds of years, with some colonies living over 4,000 years,’” reported CBS, quoting NOAA. “[T]he latest discovery reveal[ed] nearly 84,000 individual coral mound peak features ‘Over time, these slow-growing corals can build mounds that rise over 150 meters (500 feet) off the seafloor.’”
Derek Sowers, mapping operations manager for the Ocean Exploration Trust, which partnered with NOAA on the study, noted that many more corals could be out there to find because approximately half of United States’ marine waters and 75 percent of the world’s oceans have yet to be mapped.
