The Trump administration quietly released key climate change data last week that has historically been accompanied by expert analysis from government scientists at the National Oceanic and Atmospheric Administration, CNN has learned.
The lack of context minimized the government's own findings that atmospheric levels of carbon dioxide — the most abundant planet-warming gas in the air — jumped up by a record amount in 2024.
Instead of issuing a public-facing web story with an explanation of the annual measurement, as the agency has at this time of year for about a decade, NOAA public affairs officials scuttled those plans and instead released the new data on X and Facebook on April 14, sources at the agency told CNN. The social media posts link to NOAA's CO2 data-tracking web page.
The episode, along with recent budget and staffing cuts, illustrates the Trump administration's resistance to publicly distributing climate change-related data. The posts on X and Facebook, for example, did not call attention to the record-high rate of year-over-year increase in CO2 concentrations.
NOAA has also suspended monthly climate press calls during which scientists would discuss global temperatures and the reasons for particular trends. There is no indication NOAA limited its scientists' ability to speak with the press about the annual CO2 data.
A NOAA spokesperson did not reply to a request for comment.

The sustainable construction sector is shifting rapidly from incremental improvement to verified decarbonisation. New material technologies demonstrate that embodied carbon reductions no longer compromise structural or aesthetic performance. The adoption of low carbon construction materials such as advanced concretes is driving progress toward net zero whole life carbon performance, supporting the transition to genuinely sustainable building design. These innovations enable life cycle thinking in construction, where the carbon footprint of construction is assessed across supply chains and operational stages through whole life carbon assessment and robust lifecycle assessment tools.
Policy reform is reinforcing this transformation. The UK government’s ongoing review of construction product safety and environmental performance standards indicates stronger alignment between regulatory accountability and environmental sustainability in construction. Transparent environmental product declarations (EPDs) and consistent carbon reporting will underpin future requirements for sustainable building practices. This signals a move toward life cycle cost optimisation and resource efficiency in construction, advancing the shift to circular economy principles and circular economy in construction frameworks.
Global market trends add momentum. With energy security driving demand for renewable energy systems, wind-assisted shipping and floating solar are reshaping the environmental impact of construction logistics. The sector’s progress towards net zero carbon buildings depends increasingly on low carbon design, carbon neutral construction methodologies, and integration of eco-design for buildings within green infrastructure planning. As the industry adopts sustainable material specification and end-of-life reuse in construction strategies, the link between embodied carbon in materials and overall building lifecycle performance becomes measurable.
Firms slow to embed whole life carbon strategies risk losing credibility as regulation and client priorities converge around measurable sustainability outcomes. Sustainable construction now requires more than branding; it demands scientifically defensible evidence of carbon footprint reduction and adherence to circular construction strategies that support the long-term decarbonising of the built environment.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
