The Trump administration has stopped reporting research that higher temperatures can damage crops and pose health risks

The Trump administration has refused to publicize dozens of government-funded studies that carry warnings about the effects of climate change, defying a longstanding practice of touting such findings by the Agriculture Department’s acclaimed in-house scientists.

The studies range from a groundbreaking discovery that rice loses vitamins in a carbon-rich environment — a potentially serious health concern for the 600 million people world-wide whose diet consists mostly of rice — to a finding that climate change could exacerbate allergy seasons to a warning to farmers about the reduction in quality of grasses important for raising cattle.

All of these studies were peer-reviewed by scientists and cleared through the non-partisan Agricultural Research Service, one of the world’s leading sources of scientific information for farmers and consumers.

None of the studies were focused on the causes of global warming – an often politically charged issue. Rather, the research examined the wide-ranging effects of rising carbon dioxide, increasing temperatures and volatile weather.

The administration, researchers said, appears to be trying to limit the circulation of evidence of climate change and avoid press coverage that may raise questions about the administration’s stance on the issue.

“The intent is to try to suppress a message — in this case, the increasing danger of human-caused climate change,” said Michael Mann, a leading climate scientist at Pennsylvania State University. “Who loses out? The people, who are already suffering the impacts of sea level rise and unprecedented super storms, droughts, wildfires and heat waves.”

Agriculture Secretary Sonny Perdue, who has expressed skepticism about climate science in the past and allegedly retaliated against in-house economists whose findings contradicted administration policies, declined to comment. A spokesperson for USDA said there have been no directives within the department that discouraged the dissemination of climate-related science.

“Research continues on these subjects and we promote the research once researchers are ready to announce the findings, after going through the appropriate reviews and clearances,” the spokesperson said in an email.

“USDA has several thousand scientists and over 100,000 employees who work on myriad topics and issues; not every single finding or piece of work solicits a government press release,” the spokesperson added.

However, a POLITICO investigation revealed a persistent pattern in which the Trump administration refused to draw attention to findings that show the potential dangers and consequences of climate change, covering dozens of separate studies. The administration’s moves flout decades of department practice of promoting its research in the spirit of educating farmers and consumers around the world, according to an analysis of USDA communications under previous administrations.

The lack of promotion means research from scores of government scientists receives less public attention. Climate-related studies are still being published without fanfare in scientific journals, but they can be very difficult to find. The USDA doesn’t post all its studies in one place.

Since Trump took office in January 2017, the Agricultural Research Service has issued releases for just two climate-related studies, both of which had findings that were favorable to the politically powerful meat industry. One found that beef production makes a relatively small contribution to greenhouse gas emissions and another that removing animal products from the diet for environmental reasons would likely cause widespread nutritional problems. The agency issued a third press release about soy processing that briefly mentioned greenhouse gas emissions, noting that reducing fossil fuel use or emissions was “a personal consideration” for farmers.

By contrast, POLITICO found that in the case of the groundbreaking rice study USDA officials not only withheld their own prepared release, but actively sought to prevent dissemination of the findings by the agency’s research partners.

Researchers at the University of Washington had collaborated with scientists at USDA, as well as others in Japan, China and Australia, for more than two years to study how rising carbon dioxide in the atmosphere could affect rice — humanity’s most important crop. They found that it not only loses protein and minerals, but is also likely to lose key vitamins as plants adapt to a changing environment.

The study had undergone intensive review, addressing questions from academic peers and within USDA itself. But after having prepared an announcement of the findings, the department abruptly decided not to publicize the study and urged the University of Washington to hold back its own release on the findings, which two of their researchers had co-authored.

In an email to staffers dated May 7, 2018, an incredulous Jeff Hodson, a UW communications director, advised his colleagues that the USDA communications office was “adamant that there was not enough data to be able to say what the paper is saying, and that others may question the science.”

“It was so unusual to have an agency basically say: ‘Don’t do a press release,’ ” Hodson recalled in an interview. “We stand for spreading the word about the science we do, especially when it has a potential impact on millions and millions of people.”

Researchers say the failure to publicize their work damages the credibility of the Agriculture Department and represents an unwarranted political intrusion into science.

“Why the hell is the U.S., which is ostensibly the leader in science research, ignoring this?” said one USDA scientist, who spoke on the condition of anonymity to avoid the possibility of retaliation. “It’s not like we’re working on something that’s esoteric … we’re working on something that has dire consequences for the entire planet.”

“You can only postpone reality for so long,” the researcher added.

With a budget of just over $1 billion, the USDA’s Agricultural Research Service — known as ARS — is often referred to as “one of the best kept secrets” in the sprawling department because of its outsize impact on society. The agency has pioneered a variety of major breakthroughs, from figuring out how to mass produce penicillin so it could be widely used during World War II to coming up with creative ways to keep sliced apples from browning, and has for decades been at the forefront of understanding how a changing climate will affect agriculture.

The agency has stringent guidelines to prevent political meddling in research projects themselves. The Trump administration, researchers say, is not directly censoring scientific findings or black-balling research on climate change. Instead, they say, officials are essentially choosing to ignore or downplay findings that don’t line up with the administration’s agenda.

Some scientists see the fact that the administration has targeted another research arm of USDA, the Economic Research Service, as a warning shot. Perdue is moving ERS out of Washington, which some economists see as retribution for issuing reports that countered the administration’s agenda, as POLITICO recently reported.

“There’s a sense that you should watch what you say,” said Ricardo Salvador, director of the food and environment program at the Union of Concerned Scientists. “It’s going to result in some pretty big gaps in practical knowledge. … it will take years to undo the damage.”

Among the ARS studies that did not receive publicity from the Agriculture Department are:

>> A 2017 finding that climate change was likely to increase agricultural pollution and nutrient runoff in the Lower Mississippi River Delta, but that certain conservation practices, including not tilling soil and planting cover crops, would help farmers more than compensate and bring down pollutant loads regardless of the impacts of climate change.

>> A January 2018 finding that the Southern Plains — the agriculture-rich region that stretches from Kansas to Texas — is increasingly vulnerable to the effects of climate change, from the crops that rely on the waning Ogallala aquifer to the cattle that graze the grasslands.

>> An April 2018 finding that elevated CO2 levels lead to “substantial and persistent” declines in the quality of certain prairie grasses that are important for raising cattle. The protein content in the grass drops as photosynthesis kicks into high gear due to more carbon dioxide in the atmosphere — a trend that could pose health problems for the animals and cost ranchers money.

>> A July 2018 finding that coffee, which is already being affected by climate change, can potentially help scientists figure out how to evaluate and respond to the complex interactions between plants, pests and a changing environment. Rising CO2 in the atmosphere is projected to alter pest biology, such as by making weeds proliferate or temperatures more hospitable to damaging insects.

>> An October 2018 finding, in conjunction with the USDA Forest Service, that climate change would likely lead to more runoff in the Chesapeake Bay watershed during certain seasons.

>> A March 2019 finding that increased temperature swings might already be boosting pollen to the point that it’s contributing to longer and more intense allergy seasons across the northern hemisphere. “This study, done across multiple continents, highlights an important link between ongoing global warming and public health—one that could be exacerbated as temperatures continue to increase,” the researchers wrote.

Those were among at least 45 ARS studies related to climate change since the beginning of the Trump administration that did not receive any promotion, according to POLITICO’s review. The total number of studies that have published on climate-related issues is likely to be larger, because ARS studies appear across a broad range of narrowly focused journals and can be difficult to locate.

Five days after POLITICO presented its findings to the department and asked for a response, ARS issued a press release on wheat genetics that used the term “climate change.” It marked the third time the agency had used the term in a press release touting scientific findings in two and a half years.

While spokespeople say Perdue, the former Georgia governor who has been agriculture secretary since April 2017, has not interfered with ARS or the dissemination of its studies, the secretary has recently suggested that he’s at times been frustrated with USDA research.

“We know that research, some has been found in the past to not have been adequately peer-reviewed in a way that created wrong information, and we’re very serious when we say we’re fact-based, data-driven decision makers,” he said in April, responding to a question from POLITICO. “That relies on sound, replicable science rather than opinion. What I see unfortunately happening many times is that we tried to make policy decisions based on political science rather than on sound science.”

President Donald Trump, for his part, has been clear about his views on climate science and agricultural research generally: He doesn’t think much of either.

In each of his budgets, Trump has proposed deep cuts to agricultural research, requests that ignore a broad, bipartisan coalition urging more funding for such science as China and other competitors accelerate their spending. Congress has so far kept funding mostly flat.

The president has also repeatedly questioned the scientific consensus on climate change. After the government released its latest national climate assessment in November, a sweeping document based on science, Trump bluntly told reporters: “I don’t believe it.”

Officials at USDA apparently took the hint and the department did not promote the report, despite the fact that it was drafted in part by its own scientists and included serious warnings about how a changing climate poses a threat to farmers and ranchers across the country.

It’s human nature, react when you hurt.

It must be very hard to understand when you get your food from a store, and it can come from any place in the world, that world production barely balances demand and is very dependent on things like temperature and variability of water at the right time. Things that you are protected from in daily life.

Much of the population sees humanity as Lords of the Universe, not part of it. How serious this mistake is will soon be upon us.
