A recent study has revealed that many Americans think that global warming is different than climate change. Besides, they believe that global warming is the one that poses the threat of catastrophe and climate change is not a big reason to worry. Well, this is what the study carried out by Yale Researchers has found.

The study researchers said using one phrase or the other had a deep impact on how Americans express concerns for rise in earth's temperature.

"Those two terms get heard and interpreted in very different ways. The choice of these two terms really does matter, depending on who you are talking two", said Anthony Leiserowitz, one of the lead authors of the study.

Only 13% are likely to express climate change as a big concern to worry about. However, global warming has a much better chance to elicit a concern from Americans.

It could also be the result of advises given to George W. Bush in 2002 by Republican political consultants to phase out the use of 'global warming' in favor of the less dire sounding climate change.

The researchers explained that global warming is considered more serious by Americans because of catastrophic connotations attached to it. Climate change, on the other hand, has more controllable and less emotional challenge.

It is very important for the scientific community to understand who they are speaking with while talking on a complicated issue like global warming, because if not said clearly then people could have a different meaning of the original thing.
