Dennis Avery


Dennis T. Avery



Dennis Avery is the director of the Center for Global Food Issues at the Hudson Institute, where he edits Global Food Quarterly.

According to his biography at the Center for Global Food Issues, Avery is a supporter of biotechnology, pesticides, irradiation, factory farming and free trade. He also considers himself an expert on “agriculture, environment, world hunger issues, biotechnology and pesticides, trade, and water issues.”

In addition to his self-professed areas of expertise, Avery frequently comments on global warming science and policy. [2]

Stance on Climate Change

According to the summary of a study conducted by Avery and Fred Singer: “Considered collectively, there is clear and convincing evidence of a 1,500-year climate cycle. And if the current warming trend is part of an entirely natural cycle, as Singer and Avery conclude, then actions to prevent further warming would be futile, could impose substantial costs upon the global economy and lessen the ability of the world's peoples to adapt to the impacts of climate change.” [3]

Avery has also said that the next twenty to thirty years will bring us cooler temperatures: “The earth's temperatures have dropped an average of .6 Celsius in the last two years. The Pacific Ocean is telling us, as it has told us 10 times in the past 400 years, you're going to get cooler.” [4]

Key Quotes

“Why did most of our moderate modern warming take place before 1940 (with 1934 being the warmest year) and why haven't we had any warming over the last nine years? Could it possibly be the moderate natural 1,500-year cycle revealed in the ice cores and seabed sediments?” [5]

Key Deeds

March 23, 2017

Avery was a speaker at the Heartland Institute's 12th International Conference on Climate Change (ICCC12). He spoke on a panel titled “Fossil Fuels and World Peace,” along with Craig D. Idso and Aaron Stover. See video below. [14]

May 21 - 23, 2012

Dennis Avery was a speaker at the Heartland Institute's 7th International Conference on Climate Change (ICCC7).

DeSmogBlog researched the co-sponsors behind Heartland's ICCC7 and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations.

Heartland's president Joe Bast revealed at the end of the conference that the Institute has no plans for future ICCCs. This could be in part due to the defections of corporate sponsors following Heartland's unsuccessful Unabomber billboard campaign and the unintended release of their confidential documents.

Spoke at the Heartland Institute's 2008 International Conference on Climate Change. [6]

April 16, 2007

Avery wrote an article that disagrees with banning DDT in North America and Europe as well as reducing its use in third-world countries. Avery's article indirectly compares Rachel Carson, whose books inspired the ban on DDT and the creation of the Environmental Protection Agency, to Adolf Hitler:

Avery believes that the ban on DDT led to the death of “five times as many as Hitler killed in his concentration camps.” He describes the ban on DDT as causing the majority of “poverty and human degradation today.” [7]

September 11, 2006

Avery co-published a book with prolific climate change skeptic S. Fred Singer titled Unstoppable Global Warming Every 1,500 Years where they argue that global warming is a natural phenomenon.

Avery has also given numerous talks describing why he believes global warming is not caused by man. For example, this talk was sponsored by the Heartland Institute. A scientist from RealClimate attended Avery's talk and later wrote an article countering Avery's points. [8], [9]

August 2, 2002

Avery was signatory to an open letter co-authored by Myron Ebell and Fred L. Smith that supported President Bush's decision not to attend the World Summit on sustainable Development. [13]

“Although so-called environmental groups may in the next few weeks pressure you to attend, we believe there are good reasons not to give in to this pressure,” signatories wrote. [13]

April, 1993

An April, 1993 Wall Street Journal opinion piece cites Avery as claiming organic farming would produce more cancer, not less because “it's hard to get kids to eat shabby-looking produce.” [10]

Avery made similar claims in 1999 when he said that “Organic is now obviously the deadly choice in food” and claimed that organic foods are more dangerous for human consumption than those treated with chemicals. [11]

Avery is author of Global Food Progress (1991) and Saving the Planet with Pesticides and Plastic: The Environmental Triumph of High-Yield Farming, both published by the Hudson Institute.

In Saving the Planet Avery argues that using chemical pesticides, fertilizers and biotechnology is “the solution to environmental problems.” 

The Hudson Institute has received grants from numerous companies involved in the argi-business sector including Monsanto, Cargill, and CropLife International.
