What are Donald Trump’s main statements and positions on global warming
Donald Trump has frequently described climate change as a concept created to harm U.S. competitiveness, calling it “the Chinese hoax” in a 2012 tweet and repeatedly asserting that the climate has always been changing. As president, he rolled back dozens of environmental regulations, announced U.S. withdrawal from the Paris Climate Agreement, and argued that environmental rules hurt jobs. In public comments, he has alternated between outright rejection of human-caused climate change, claims that climate science is unsettled, and occasional acknowledgments that the climate is changing but questioning the extent of human influence. This evergreen explainer outlines those remarks and policy shifts in verifiable detail.
Key remarks on climate and global warming
Early tweets and public claims
Long before his presidency, Donald Trump used social media to question established climate science. In a 2012 post widely cited in media and fact checks, he wrote: “The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.” He repeated variations of this claim in subsequent years and framed climate policies as job killers. Such statements established a baseline public narrative that climate concern was a hoax or plot against American industry.
Presidential statements and terminology
As president, Trump consistently referred to climate change as “global warming” in ways that emphasized skepticism about warming trends. During rallies and interviews, he asserted that icebergs were the largest contributors to sea level rise and suggested that the planet would “start getting cooler soon.” These remarks often diverged from scientific consensus, which emphasizes greenhouse gas accumulation from human activity as the primary driver of observed warming.
Policy actions and regulatory changes
Rollback of environmental rules
The Trump administration pursued a wide-ranging deregulatory agenda affecting climate and energy policy. Key moves included repealing the Clean Power Plan, loosening vehicle emissions standards, narrowing the scope of waters protected under the Clean Water Act, and easing rules on methane leaks from oil and gas operations. Proponents argued these changes would boost energy independence and jobs; critics said they weakened pollution controls and increased long-term climate risks.
Paris Agreement withdrawal
In 2017, the administration announced its intention to withdraw from the Paris Climate Agreement, arguing that the accord disadvantaged the United States while advantaging large emitters such as China. The formal withdrawal took effect in 2020. During negotiations, Trump representatives emphasized a preference for voluntary commitments and bilateral deals over legally binding targets.
Statements on energy and industry
Fossil fuels and deregulation
Trump framed fossil fuel production as synonymous with national strength, promoting coal, oil, and natural gas extraction and criticizing limits on drilling. He directed federal agencies to accelerate permits for pipelines and other energy infrastructure, arguing that stringent environmental reviews delayed projects and cost jobs. Simultaneously, his administration opened more federal lands and offshore areas to oil and gas leasing.
Renewables and climate resilience spending
While Trump frequently praised natural gas and coal, he was skeptical of subsidies for wind and solar, calling them unreliable and costly. He also questioned the need for federal spending on climate resilience, suggesting that such projects were wasteful. In contrast, many state and local governments moved ahead with their own climate adaptation plans despite federal pullback.
Public reception and expert assessments
Scientific community response
Climate scientists and major scientific bodies largely rejected Trump’s claims that climate change is a hoax. Surveys of peer-reviewed literature show overwhelming consensus that humans are the dominant cause of recent warming. Reports from the U.S. Global Change Research Program and international assessments stated that climate impacts are already intensifying and that rapid emissions reductions are necessary to limit risks.
International reactions
When the U.S. announced its Paris Agreement withdrawal, many countries reaffirmed their commitments and expressed disappointment. European leaders and developing nations emphasized that the move weakened global momentum on climate action. Others noted that subnational actors, businesses, and civil society in the United States would continue climate efforts even at the federal level.

Context and common questions
Did Trump ever acknowledge any role for human activity in climate change
In some settings, Trump acknowledged that the climate is changing but questioned whether human activity was the primary driver. He often emphasized uncertainty in climate science and pointed to costs of regulation. These comments contrast with assessments from major scientific organizations, which state that human influence is the dominant cause of observed warming since the mid-20th century.
How do experts evaluate his positions on global warming
Climate scientists and assessments by bodies such as the Intergovernmental Panel on Climate Change and the U.S. Global Change Research Program generally concluded that Trump’s positions diverged from the scientific evidence. Their findings highlight risks from continued emissions, the importance of mitigation and adaptation, and the consensus that human activities are the main driver of recent climate change.
Moving forward: what to watch
Even after leaving office, Trump&rsquoz positions continue to shape climate and energy discourse in U.S. politics. Future policy debates, regulatory changes, and international negotiations may be influenced by how his supporters and successors frame the issue of global warming. Observers watch for shifts in rhetoric, changes to federal rules, and whether commitments to decarbonization align with or diverge from scientific recommendations.
Frequently asked questions
- What did Donald Trump say about global warming on social media? He called it a hoax invented to hurt U.S. manufacturing and claimed it was created by China to make America non-competitive.
- Did Trump keep any climate or environmental rules in place? While he rolled back many major rules, some existing regulations remained in place due to legal challenges and slower timelines for agency action.
- What happened to U.S. climate policy after Trump left office? The Biden administration rejoined the Paris Agreement and began developing new climate and clean energy rules, though some changes face legal and political hurdles.
- How do scientists view claims that climate change is a natural cycle with no human influence? The vast body of peer-reviewed research indicates that recent warming is primarily driven by human emissions of greenhouse gases, not natural cycles alone.
- Did Trump ever propose climate legislation or market-based solutions like carbon pricing? Generally no; his administration favored deregulation and fossil fuel production over new climate legislation or carbon pricing mechanisms.
Key terms
- Global warming: Long-term rise in the average temperature of Earth’s climate system, an aspect of climate change.
