Oil giant ExxonMobil, long criticized over its stance on climate change and production of fossil fuels, has appointed a leading climate scientist to its board of directors.

Susan Avery, an atmospheric physicist and former president of the famed Woods Hole Oceanographic Institution, will join the board of the petroleum giant on February 1, the company announced late Wednesday.

Avery's research priorities have included climate variability, and she has said that "Clearly climate science is telling us get off fossil fuels as much as possible."

She has a "keen interest in scientific literacy and the role of science in public policy," according to the website for Woods Hole, which is based in the northeastern state of Massachusetts.

ExxonMobil remains a primary target of environmentalists for its contribution to fossil fuel consumption. 

It was the subject of a 2015 investigative news reports charging it "manufactured doubt" about climate science even while contradicted by research by its own climate scientists, according to environmental news nonprofit Inside Climate News.

ExxonMobil has dismissed those reports as biased, but it faces government investigations over the controversy.

Earlier this month, a Massachusetts court ruled the oil giant must turn over 40 years of documents on climate change, in a win for Massachusetts Attorney General Maura Healey, who has described the probe as a fraud investigation. 

ExxonMobil has countersued against Healey, arguing she lacks jurisdiction in the matter.

The appointment of a climate scientist to the company's board comes as climate scientists gird for combat with the Trump administration, whose pick for to head the Environmental Protection Agency, Scott Pruitt, is a climate skeptic.

A group of scientists this week announced plans for a "Scientists' March on Washington," although no date has been set. 

"There are certain things that we accept as facts with no alternatives. The Earth is becoming warmer due to human action," the group said on its website.
