This 1997 Global Climate Coalition (GCC) document cast doubt on the climate models used to predict climate change. The industry-funded GCC opposed greenhouse gas regulations through direct engagement and collaboration with affiliated climate deniers from 1989 to 2002. Its membership spanned across the automotive, utility, manufacturing, petroleum, and mining industries.

In this publication, the GCC claimed that climate models were, “imperfect at best and have produced highly inaccurate projections of climate change.” The GCC doubted whether computers would ever be capable of generating accurate models because, “a model incorporating every possible climate variable would be too complex to run on even the most advanced computer.”

The GCC also claimed that there had been no warming in the US, stating, “the observed warming trend is within the range of natural variation,” and that “… according to some computer simulations of the greenhouse effect, the average temperature in the United States should have increased by approximately 1.5 degrees Celsius during the past 100 years. Information collected by the national Climatic Data Center shows no significant warming in the US.”
