Then during Trump's first 100 days in office, the new administration gradually excised mentioned of climate change from government websites.

Now the feud between the Trump administration and scientists has escalated again with the leak of an unreleased federal study on climate change to the New York Times.

"An article on Tuesday about a sweeping federal climate change report referred incorrectly to the availability of the report", TheNYT wrote in its correction issued Wednesday morning. The planet is steadily inching toward an average increase in global temperature of 2 degrees Celsius, the point that sets alarm bells ringing for scientists who warn of climate catastrophe.

And according to the publication, the document says it is "extremely likely" that more than half of the global average temperature rise since 1951 could be linked to humans.

"There are no alternative explanations" to human industrial activity being the cause, it adds, and "no natural cycles are found in the observational record that can explain the observed changes in climate".

The draft paper reveals the average temperature across the United States has risen sharply since the 1980s, and lays the blame at the door of human activities, especially greenhouse gas emissions, which it says are "primarily responsible" for recent observed climate change.

The congressionally mandated report, produced by 13 federal agencies, summarizes climate science for the upcoming National Climate Assessment, which is done every four years.

"This is a draft report that has been in the public domain since January", EPA spokeswoman Liz Bowman said in a statement to Geek.

In its six months to date, it chose a climate-science denier to lead the Environmental Protection agency; rolled back two dozen regulations limiting air, water, and land pollution; and announced a US withdrawal from the Paris Climate Agreement to limit carbon emissions. We ask that any comments by climate-change denialists be flagged for moderation.

"It's kind of incomprehensible to me that there is still any debate by anybody in government that the climate system is changing, and it's changing primarily because of human activities", he said. President Trump becoming the savior of intellectual honesty on the right on climate change wouldn't be the weirdest thing to happen in American politics, but it'd be close.

President Donald Trump has promised to bring back coal mining jobs, extend oil pipelines, and reduce government subsidies for clean energy initiatives and now USA scientists are fighting back.

Pruitt has already taken the position that human emissions of greenhouse gases are not the main cause of global warming, which is contrary to the findings of his agency's scientists, as well as experts around the world.

Scientists say they fear the Trump administration could change or suppress the report.

The draft report has, however, proven that Trump's claims on climate change are not true.

Recent decades have seen marked changes in temperature extremes across the U.S. This chart shows that record warm daily temperatures are occurring more often.
