The recently appointed (by Donald trump) chief of the US Environmental Protection Agency disagrees with majority scientific consensus on CO2 links to warming.
The EPA’s website notes that carbon dioxide is the “primary greenhouse gas that is contributing to recent climate change”.
Data released in January by NASA and the US National Oceanic and Atmospheric Administration said the planet’s rising temperature has been “driven largely by increased carbon dioxide and other human-made emissions in the atmosphere”.
The two US agencies added that the earth’s 2016 temperatures were the warmest ever.
Scott Pruitt told CNBC that measuring human impact on the climate was “very challenging” and there was “tremendous disagreement” about the issue.
Mr Pruitt, chief of the EPA, instead insisted that officials needed “to continue the debate” on the issue.
His remarks contradict his own agency’s findings on greenhouse gas emissions.
Isn’t that why he was chosen by Trump to head the EPA?
Mr Pruitt, 48, who was sworn in last month, is considered one of President Donald Trump’s most controversial appointments due to his ties to the fossil fuel industry.
The former Oklahoma attorney general also spent years legally challenging the reach of the organisation he now heads.
During his confirmation hearing in January, Mr Pruitt did say he believed humans had contributed to climate change, though he was not sure how much.
Perhaps he should learn something about what his agency does.
Mr Trump tweeted in 2012 that global warming was a “hoax”, but he said last November “I think there is some connectivity” between humans and the changing climate.
Trump is well known for promoting hoaxes and conspiracies. He is also well known for changing his tune.
