Watch: "On Thin Ice"

“There is no conclusive scientific evidence to link global warming with what is happening in the Himalayan glaciers,” said Jairam Ramesh, India’s environment minister, following a newly released report on the glaciers.

Watch: Green Jobs

But one source of job growth the president was hoping for -- creation of new jobs in green industries -- has proved elusive. For myriad reasons, including the outsourcing of such jobs to China, growth in clean energy industries and in green jobs has been slower than expected.

To get a better understanding of the future of such jobs, David Brancaccio spoke to Van Jones, who at that time was a special advisor for green jobs, enterprise and innovation at the White House. Jones has since stepped down from his position amidst controversy over some of his past statements.

Jones told NOW how green collar jobs could save the country money and offer more jobs in the future.
