13% of Americans have never heard of ‘global warming’

In a classic case of the worst offender being oblivious…

OSLO (Reuters) - Thirteen percent of Americans have never heard of global warming even though their country is the world’s top source of greenhouse gases, a 46-country survey showed on Monday.

The report, by ACNielsen of more than 25,000 Internet users, showed that 57 percent of people around the world considered global warming a “very serious problem” and a further 34 percent rated it a “serious problem.”

“It has taken extreme and life-threatening weather patterns to finally drive the message home that global warming is happening and is here to stay unless a concerted, global effort is made to reverse it,” said Patrick Dodd, the President of ACNielsen Europe.

People in Latin America were most worried while U.S. citizens were least concerned with just 42 percent rating global warming “very serious.”
