President-elect Trump's pick to lead the Energy Department Chris Wright walked a fine line Wednesday as he called climate change "a real and global phenomenon" but remained skeptical during his U.S. Senate confirmation hearing.

Wright, the founder of a fracking firm, testified that he would back all forms of low-carbon energy as well as gas, oil and coal.

Chris Wright, the fracking company CEO who Trump has nominated to lead the Department of Energy and who had previously claimed “there is no climate crisis,” admitted that climate change is a “real issue” during his confirmation hearings on Wednesday.
