New Research Further Demonstrates Problems with Surface Temperature Records and Models

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.

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.

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.

Hyundai moves SUV production to U.S.

Published on April 25, 2025

Quick Hit:

Hyundai is responding swiftly to 47th President Donald Trump’s newly implemented auto tariffs by shifting key vehicle production from Mexico to the U.S. The automaker, heavily reliant on the American market, has formed a specialized task force and committed billions to American manufacturing, highlighting how Trump’s America First economic policies are already impacting global business decisions.

Key Details:

Hyundai has created a tariffs task force and is relocating Tucson SUV production from Mexico to Alabama.
Despite a 25% tariff on car imports that began April 3, Hyundai reported a 2% gain in Q1 operating profit and maintained earnings guidance.
Hyundai and Kia derive one-third of their global sales from the U.S., where two-thirds of their vehicles are imported.

Diving Deeper:

In a direct response to President Trump’s decisive new tariffs on imported automobiles, Hyundai announced Thursday it has mobilized a specialized task force to mitigate the financial impact of the new trade policy and confirmed production shifts of one of its top-selling models to the United States. The move underscores the gravity of the new 25% import tax and the economic leverage wielded by a White House that is now unambiguously prioritizing American industry.

Starting with its popular Tucson SUV, Hyundai is transitioning some manufacturing from Mexico to its Alabama facility. Additional consideration is being given to relocating production away from Seoul for other U.S.-bound vehicles, signaling that the company is bracing for the long-term implications of Trump’s tariffs.

This move comes as the 25% import tax on vehicles went into effect April 3, with a matching tariff on auto parts scheduled to hit May 3. Hyundai, which generates a full third of its global revenue from American consumers, knows it can’t afford to delay action. Notably, U.S. retail sales for Hyundai jumped 11% last quarter, as car buyers rushed to purchase vehicles before prices inevitably climb due to the tariff.

Despite the trade policy, Hyundai reported a 2% uptick in first-quarter operating profit and reaffirmed its earnings projections, indicating confidence in its ability to adapt. Yet the company isn’t taking chances. Ahead of the tariffs, Hyundai stockpiled over three months of inventory in U.S. markets, hoping to blunt the initial shock of the increased import costs.

In a significant show of good faith and commitment to U.S. manufacturing, Hyundai last month pledged a massive $21 billion investment into its new Georgia plant. That announcement was made during a visit to the White House, just days before President Trump unveiled the auto tariff policy — a strategic alignment with a pro-growth, pro-America agenda.

Still, the challenges are substantial. The global auto industry depends on complex, multi-country supply chains, and analysts warn that tariffs will force production costs higher. Hyundai is holding the line on pricing for now, promising to keep current model prices stable through June 2. After that, however, price adjustments are on the table, potentially passing the burden to consumers.

South Korea, which remains one of the largest exporters of automobiles to the U.S., is not standing idle. A South Korean delegation is scheduled to meet with U.S. trade officials in Washington Thursday, marking the start of negotiations that could redefine the two nations’ trade dynamics.

President Trump’s actions represent a sharp pivot from the era of global corporatism that defined trade under the Obama-Biden administration. Hyundai’s swift response proves that when the U.S. government puts its market power to work, foreign companies will move mountains — or at least entire assembly lines — to stay in the game.

Trump tells Zelensky: Accept peace or risk ‘losing the whole country’

Quick Hit:

President Donald Trump warned Ukrainian President Volodymyr Zelensky that he risks losing Ukraine entirely if he continues resisting a peace settlement. Trump said Moscow is ready for peace, but Kyiv’s refusal to recognize Crimea as Russian territory could derail the effort.

Key Details:

Trump said Zelensky “can have Peace or… lose the whole Country” and claimed Russia is ready to make a deal.
Zelensky reiterated Ukraine’s refusal to recognize Russia’s occupation of Crimea, a key sticking point in current peace talks.
White House press secretary Karoline Leavitt said Trump is frustrated and warned peace efforts may end if no deal is reached this week.

Diving Deeper:

President Trump issued a blunt warning to Ukrainian President Volodymyr Zelensky on Wednesday, saying the Ukrainian leader must choose between accepting peace or facing the collapse of his nation.

“He can have Peace or… fight for another three years before losing the whole Country,” Trump posted on Truth Social. The statement followed Zelensky’s firm declaration that Ukraine “will not legally recognize the [Russian] occupation of Crimea,” a stance at odds with a proposed peace plan under discussion in London between U.S., British, and European officials.

Trump blasted Zelensky’s comment as damaging, declaring, “Crimea was lost years ago under the auspices of President Barack Hussein Obama, and is not even a point of discussion.” The president added that such rhetoric undermines delicate peace negotiations.

Speaking from the Oval Office, Trump said, “I think Russia is ready,” referring to a peace deal, but questioned whether Ukraine is. Kyiv reportedly signed on to a Trump-proposed ceasefire more than a month ago. Trump hinted that progress has been stymied by Zelensky’s reluctance to compromise.

Despite Russian officials signaling a desire to prolong negotiations—with Kremlin spokesman Dmitry Peskov dismissing Trump’s efforts as “futile”—Trump maintained optimism, stating, “I think we have a deal with Russia… we have to get a deal with Zelensky.”

White House press secretary Karoline Leavitt said Trump’s patience is wearing thin. “President Zelensky has been trying to litigate this peace negotiation in the press, and that’s unacceptable,” she said, calling for closed-door diplomacy. “The American taxpayer has funded billions… enough is enough.”

Trump, 78, has consistently criticized Obama for allowing Russia’s 2014 annexation of Crimea to go unanswered. Now, under the Trump administration’s push for peace, a senior official revealed the U.S. is considering recognizing Crimea as Russian territory—a reversal of longstanding American policy based on the 1940 Welles Declaration.

Still, Trump refrained from criticizing Vladimir Putin directly, instead blaming Zelensky for inflammatory statements. “He has nothing to boast about!” Trump said, referencing a heated Feb. 28 Oval Office exchange with Zelensky and Vice President JD Vance.

“I have nothing to do with Russia,” Trump wrote, “but have much to do with wanting to save… five thousand Russian and Ukrainian soldiers a week.”

Trump warned that time is running out: “We are very close to a Deal, but the man with ‘no cards to play’ should now, finally, GET IT DONE.”

With London talks underway and pressure mounting, officials hinted that if no agreement is reached this week, the U.S. could walk away from its efforts in Eastern Europe. Asked whether Trump is ready to give up, Leavitt said, “Not by the end of the day today… but the President… needs to see this thing come to an end.”
