You have got to be kidding me...

According to a 46 country AC Neilsen study, 13% of Americans said they had never heard or read anything about global warming

13%? Who are these people? Where have they spent the last 5 or 10 years?

And of 46 countries, America was the least concerned about global warming.

The US releases 25 % of the world's greenhouse gases.

Is it possible these pieces of information are related?
