Here’s the Worst, Anti-Science Idea of the Week from the Republican Congress

The head of the House science committee is pissed about research into Monsanto’s Roundup herbicide.

At a hearing this week, Rep. Lamar Smith (R.-Texas) lashed out at the International Agency for Research on Cancer (IARC), the group that assesses cancer risk for the UN’s World Health Organization. He accused it of conducting “cherry-picked science,” which, he declared “raises questions about why IARC should receive any [US] government funding in the future.”

“Cherry-picked science” is quite a charge coming from Smith, a magnate for cash from the fossil fuel and agribusiness industries who is widely regarded as the “preeminent climate change denier in Congress,” to use the veteran Los Angeles Times reporter Michael Hiltzik’s phrase.

What drew Smith’s ire is an ongoing dispute over the herbicide glyphosate, marketed by Monsanto as Roundup. In an assessment of the scientific literature back in 2015, IARC declared glyphosate “probably carcinogenic to humans.” The finding triggered a fierce pushback from Monsanto as well as a flood of pending lawsuits from cancer survivors

Controversy has roiled around the assessment ever since. Last June, Reuters reported that the agency had failed to consider relevant unpublished data from a study suggesting glyphosate doesn’t cause cancer. The IARC responded that its policy is to never consider unpublished studies in its assessment, and it has since fiercely defended is conclusion.  

Some scientists defend the IARC’s position, such as the 100 US and worldwide researchers who signed this 2016 paper in the Journal of Epidemiological Community Health. Others authorities dispute it, including the US Environmental Protection Agency and its counterpart across the Atlantic, the European Food Safety Agency, both of which have declared glyphosate not likely to be carcinogenic. 

In other words, there is genuine scientific disagreement about whether glyphosate poses a cancer risk. In an ideal world, the views of a science-denying zealot like Lamar Smith would have little bearing on the debate. In reality, he’s a powerful figure in a party that controls Congress and the White House. And he chairs the US House’s Science, Space, and Technology Committee, a spot he will hold until he retires at the end of his term in 2019.

But even if Congress slashes US financial support for the IARC, it won’t likely have a huge effect on its funding. According to a 2017 Reuters piece, the agency’s budget is just $34 million per year, and the United States has contributed just $40 million to it since 1992—which amounts to roughly $1.6 million a year, or less than 5 percent of IARC’s annual budget. 

$500,000 MATCHING GIFT

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones: A special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of the huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
