The Environmental Protection Agency announced Friday evening that its website would be âundergoing changesâ to better represent the new direction the agency is taking, triggering the removal of several agency websites containing detailed climate data and scientific information.
One of the websites that appeared to be goneÂ had been cited to challenge statements made by the EPAâs new administrator, Scott Pruitt. Another provided detailed information on the previous administrationâs Clean Power Plan, including fact sheets about greenhouse gas emissions on the state and local levels and how different demographic groups were affected by such emissions.
The changes came less than 24 hoursÂ before thousands of protesters were set to march in Washington and around the country in support of political action to push back againstÂ the Trump administrationâs rollbacks of former president Barack Obamaâs climate policies.
âAs EPA renews its commitment to human health and clean air, land, and water, our website needs to reflect the views of the leadership of the agency,â J.P. Freire, the agencyâs associate administrator for public affairs, said in a statement. âWe want to eliminate confusion by removing outdated language first and making room to discuss how weâre protecting the environment and human health by partnering with states and working within the law.â
The agency also said it would carefully archive pages from the past administration.
The change was approved by Pruitt, according to an individual familiar with the matter who spoke on the condition of anonymity to discuss internal deliberations, to avoid a conflict between the siteâs content and the policies the administration is now pursuing.
The staffer described the process of reviewing the site as âa work in progress, but we canât have information which contradicts the actions we have taken in the last two months,â adding that Pruittâs aides had âfound a number of instances of that so farâ while surveying the site.
Yet the website overhaulÂ appears to include not only policy-related changes but alsoÂ scrutiny of a scientific Web page that has existed for nearly two decades, and that explained what climate change is and how it worked.
The EPAâs extensive climate change website now redirects to a page that says âthis page is being updatedâ and that âwe are currently updating our website to reflect EPAâs priorities under the leadership of President Trump and Administrator Pruitt.â It also links to a full archive of how the page used to look on Jan. 19, beforeÂ Trumpâs inauguration.
The EPAâs Friday press statement did not explicitly refer to changes affecting this site, but it did say that âcontent related to climate and regulation is also under review.â
The archived EPA climate page notes, in a key section under the âcauses of climate change,â that
Recent climate changes, however, cannot be explained by natural causes alone. Research indicates that natural causes do not explain most observed warming, especially warming since the mid-20thÂ century. Rather, it is extremely likely that human activities have been the dominant cause of that warming.
It is this language, when the site was still up, that directly contradictedÂ Pruitt. Pruitt hadÂ argued on CNBC last month that âmeasuring with precision human activity on the climate is something very challenging to do and thereâs tremendous disagreement about the degree of impact, so no, I would not agree that itâs a primary contributor to the global warming that we see.â
The EPAâs climate change website stated otherwise, and did so by citingÂ findings of the United Nationsâ Intergovernmental Panel on Climate Change.
There had been reports early in the Trump administration that the EPA climate change website was set to be taken down, but in the end it did not happenÂ immediately.
The page contains scientific explanations of climate change and its causes and consequences, and has existed in one form or another since at least 1997. At that time it was called the agencyâs Global Warming site.
âIf you are looking for information on âclimate change,â âthe greenhouse effect,â or âglobal warming, â youâve come to the right place,â it declared in August 1997. âAt this web site you will find information pertaining to the science of global warming; current and projected impacts of global warming; international and U.S. Government policies and programs; opportunities for individuals and corporations to help stop global warming (and in many cases, save money, too!); state and local actions that help mitigate greenhouse gas emissions; and, easy ways to obtain more information by fax, email and electronic order form.â
The site has long served an informational role and sought to provide a comprehensive review of basic climate science, the effects of climate change, and how it is affecting the United States. In addition it contained information about the agencyâs approach to climate change and how people could take steps to lower their own contributions to climate change.
However, the site has run into politicalÂ headwinds before. Under President George W. Bush, updates to the site were frozen and then required to undergo White House review. However, this process did not lead to substantive changes in scientific content.
âThe EPAâs climate site includes important summaries of climate science and indicators that clearly and unmistakably explain and document the impacts we are having on our planet,â said Katharine Hayhoe, a climate scientist at Texas Tech University, in response to the website change.
âItâs hard to understand why facts require revision,â she continued.
Janet McCabe, who headed EPAâs Office of Air and Radiation during Obamaâs second term, said in an interview Saturday that while âyou would expect a new administration to reflect their policies on their website,â the agency had made a point in the past of making the regulatory history of different policies available on its website even when administrations changed hands and shifted direction.
âHistorical and factual information about these issues, and regulations over time, is something that EPA has always made available to people,â McCabe said. âIt belongs to the people, and people should be able to find it easily.â
In its press statement, the EPA said that when it comes to website changes,Â âthe first page to be updated is a page reflecting President Trumpâs Executive Order on Energy Independence, which calls for a review of the so-called Clean Power Plan.â
That site,Â www.epa.gov/cleanpowerplan, nowÂ redirects toÂ https://www.epa.gov/Energy-Independence, which features an image of President Trump signing an executive order aimed at dismantling the power plant rule and other Obama-era climate regulations.
In the press statement, the EPA said that âlanguage associated with the Clean Power Plan, written by the last administration, is out-of-date.â
A group that has been closely monitoring government environmental and science websites for changes in the Trump years, the Environmental Data and Governance Initiative, had a cautious reaction to the changes.
âThe clear communication by the EPA notifying of the impending website overhaul is good transparency practice, but it remains to be seen how information and information access will change as the EPA site is updated,â saidÂ Toly Rinberg, a member of the groupâs website tracking committee.
Several career EPA employees, who asked for anonymity out of fear of retribution, said they were not briefed in advance about the decision to alter the agencyâs site.
âPeople are obviously unhappy,â one employee said. âIt is, in my opinion, the best climate education website out there.â
David Doniger, director of the climate and clean air program for the advocacy groupÂ Natural Resources Defense Council,Â tweetedÂ Friday, âCleansing has begun. EPA website scrubbed of pages on âso-calledâ Clean Power Plan. Now only alternative facts.â
Another EPA website, documenting climate change âindicatorsâ across the United States, remained up on Friday.
