U.S. Government Changes Climate Reports: What It Means for America

The United States has a long history of studying and reporting on climate change to inform policymakers, communities, and the public. One of the key tools for this is the National Climate Assessment (NCA), a detailed scientific report produced every few years. The NCA provides evidence-based insights about how climate change is impacting the country’s environment, economy, and society.

Recently in 2025, the U.S. Administration began revising and temporarily removing these National Climate Assessment reports from official government websites, sparking widespread discussion and concern. 

1. What is the National Climate Assessment?

The National Climate Assessment is a federally mandated report produced by a team of hundreds of scientists and experts across many agencies. Established under the Global Change Research Act of 1990, its goal is to provide a clear overview of how climate change is affecting the United States and what risks and opportunities arise from these changes.

• The NCA is updated approximately every four years.

• It covers diverse topics including agriculture, forestry, water resources, health, infrastructure, and ecosystems.

• The report is based on scientific research, data analysis, and peer review, ensuring high credibility.

• It informs Congress, the President, state and local governments, businesses, and the public to guide decision-making.

The most recent edition before the revision was the Fifth National Climate Assessment (NCA5), released in November 2023. It showed that climate change is impacting all regions of the U.S. with rising temperatures, more extreme weather events, droughts, floods, and disruptions to agriculture and natural habitats.

2. Recent Revision and Removal of the Reports

Starting in mid-2025, the Biden administration’s successor began taking down the online versions of the National Climate Assessment reports from official websites and announced a review process to update the content.

The Department of Energy and other officials stated that the existing reports:

• Did not fully reflect new perspectives on energy and economic policies.

• Contained what they perceived as inaccuracies or biases in climate science interpretation.

• Needed re-examination before being re-released to avoid spreading what they called "misleading or incomplete" information.

This move was framed by government spokespeople as a necessary step to ensure the reports align better with the current administration’s policies and priorities.

3. The Importance of the Reports

The NCA is important because:

• It provides a scientific basis for climate action plans and adaptation strategies at all levels of government.

• Helps industries and communities understand risks and prepare accordingly—for instance, farmers facing drought or cities preparing for flooding.

• Supports the development of policies to reduce greenhouse gas emissions and protect public health.

• Raises awareness among citizens about the reality and severity of climate change.

Removing or revising the reports may cause uncertainty, delay action, or reduce public trust in the government’s commitment to addressing climate issues.

4. Reactions from Experts, Scientists, and Climate Advocates

The revision decision has been met with strong criticism from environmental scientists and climate advocacy groups who argue that:

• The scientific findings in the existing reports are based on rigorous research and peer review.

• Revising or censoring these reports for political reasons undermines science and public knowledge.

• Delays or removal creates obstacles for climate preparedness and policy development.

• It risks promoting climate misinformation at a time when urgent action is needed globally.

Many experts have called for the reports to be reinstated immediately and for the government to maintain transparency and scientific integrity.

5. Political Context and Policy Implications

The revision coincides with a policy shift emphasizing increased fossil fuel production and use, including coal and oil, compared to previous administrations pushing for more renewable energy and emission cuts.

This shift may:

• Slow down national and state efforts to reduce carbon emissions.

• Affect the United States’ commitments under international climate agreements.

• Influence the direction of future climate-related infrastructure investments and regulations.

Critics say this could increase the risks of climate damage, while supporters argue for energy independence and economic growth.

6. What Are the Next Steps?

At present, the government has not published a timeline for releasing the revised National Climate Assessment. Experts suggest some key steps should include:

• Conducting thorough scientific review without political interference.

• Incorporating the latest climate data and projections.

• Engaging with a diverse range of stakeholders, including scientists, communities, and policymakers.

• Providing clear and accessible communication to the public.

• Ensuring the reports guide effective mitigation and adaptation efforts.

Organizations such as the U.S. Global Change Research Program continue to emphasize the need for science-based policy and transparent reporting.

7. Why the National Climate Assessment Matters for Every American

Climate change affects every aspect of life—health, safety, food, natural resources, and the economy. The National Climate Assessment is the nation’s key tool to understand these effects and prepare for them.

• Farmers and ranchers need climate data to adapt crops and protect livestock.

• Coastal communities require information to build defenses against flooding and storms.

• Cities use projections to improve infrastructure resilience.

• Health officials learn how to address rising disease risks linked to climate.

• Businesses assess risks to supply chains and markets.

Without reliable and up-to-date assessment reports, decision-makers and citizens may lack the critical information required to protect lives and livelihoods.

8. The Science Behind the Assessment

The NCA draws from a broad scientific consensus that human activity, especially greenhouse gas emissions, is the dominant cause of recent climate changes. It examines:

• Global and regional temperature increases.

• Changes in precipitation and drought frequency.

• Rising sea levels and ocean temperature.

• Increase in extreme events such as wildfires, hurricanes, and heatwaves.

• Effects on ecosystems, agriculture, and human health.

It also presents future projections based on different emission scenarios, illustrating potential pathways if greenhouse gases continue unabated or are reduced.
