The National Academy of Sciences released an 869-page report, on Wednesday, claiming the role of human beings in accelerating the climate change. The report also urged the enforcement of policies to curb the harmful effects.

The report was initiated by the Congress in 2008, endorsing the conclusions drawn by the Intergovernmental Panel on Climate Change. Another similar report released by the UN in 2007 faced criticism for encountering errors.

These errors, along with the hacking of unappealing emails from a U. K. lab have invited troubles for the climate-change scientists in the last couple of months.

IPCC will present its next report in 2014. In some areas the study has successfully provided latest climate change analyses.

Pamela Matson, dean of Stanford University's school of earth sciences said that the academy has compiled the report after carefully analyzing the scientific literature of the previous five years.

It found that there is high insecurity in predicting further about the climate change, as of now.

"The charge we got from Congress was not just to tell them what the science says but what to do about the problem," said Robert Fri, a visiting scholar

It also highlights the need of taking robust action against the excessive use of fossil fuels and proposed to enforce a tax on carbon emission.
