Social scientists who have studied Curry's position on climate change have described it as "neo-skepticism", in that her current position includes certain features of denialism; on the one hand, she accepts that the planet is slightly warming, that
human-generated greenhouse gases like carbon dioxide cause warming, and that the plausible worst-case scenario is potentially catastrophic, but on the other hand she also proposes that the rate of warming is slower than

(IPCC) reports. In the 2010 profile, she accused the IPCC of "corruption" and said she no longer had confidence in the process. She agreed that the Earth is warming, largely due to human-generated greenhouse gases such as carbon dioxide, and that the plausible worst-case scenario is potentially catastrophic. She said that the IPCC was distorting the science and scientists were not dealing adequately with uncertainties. Commenting climatologists have generally disagreed with her critiques.
Stephen Schneider, who had persuaded the IPCC to systematize discussion of uncertainty, said Curry had lately proposed "a lot of strawmen" and "It is frankly shocking to see such a good scientist take that kind of a turn to sloppy thinking. I have no explanation for it." Curry felt that although she was still able to publish professionally, she had become a victim of mainstream climate science's overreaction to criticism; she believed the climate community had adopted a fortress mentality, defending insiders and refusing access to outsiders.
Curry began her own blog open to outsider participation. It was described as part of the

study found that Curry was among the "climate doubters" most frequently quoted by the press as spreading public doubts about climate science. Going against the vast majority view of climate scientists, she had suggested to newspapers that most of the recent global warming was not human-caused, and had hinted that IPCC scientists are motivated by "funding" even though they are not paid for their contributions.
She consistently presents her view that climate science has much larger uncertainties than those shown by mainstream studies, though she has not shown any previously unconsidered cause for such uncertainty.
A 2019 article in ''Human Ecology Review'' described her position as a form of climate denialism, criticizing her downplaying of potential future climate change effects and emphasis on the costs of addressing climate change.
Political influence

Curry has repeatedly been invited as a witness to United States Congressional hearings as one of the few scientists advancing doubts about the significance of human contributions to climate change, and political figures have used Curry's statements and writings in their arguments. For instance, when

, a politician and President Trump's first appointment to the NASA transition team, questioned the role of humans in climate change, Shank referred to Curry's work and her site's URL repeatedly in his testimony.
Between 2014 and February 2019, Curry testified before at least six Republican-led House committees, expressing the idea that the dangers of global warming are overstated and difficult to predict. These testimonies include criticisms of President Obama's climate plan, the UN climate action plan, and other policy proposals aimed at reducing carbon dioxide emissions. In her Natural Resources Committee testimony on February 6, 2019, Curry stated that, "Man-made climate change is not an existential threat in the 21st century.... The perception of a near-term apocalypse has narrowed the policy options".

In February 2019, Curry was on a
