Report: Climate change was big influence of extreme weather in 2014

A recent government study suggests that climate change is behind some of the world's most extreme weather.

A team of 32 scientists from around the globe studied 28 extreme weather events from last year and found that 14 of those were made worse, in part, by climate change caused by pollution. Or, in other words, people.

Devastating floods in New Zealand and Australia, extreme heat waves in South Korea, wildfires in California, lashing rainfall in France and more were included in the count.

However, scientists say the extreme cold and record snowfall in the U.S. was not linked to climate change, rather cyclical weather patterns.

Hurricane Gonzalo over Europe and Brazil's drought were also not influenced, according to the study.

Scientists cited "huge concerns" about the results of the study. But in some part of the world, people don't share the same unease.

A Pew Research poll found that the countries that emit the most CO2 per person are also the ones least worried about the issue of climate change.

45 percent of Americans believe that global climate change is a "very serious problem" — up from 37 percent in previous years.

But in countries such as China, Japan, Australia, Russia, Germany and Poland — fewer than 20 percent of respondents said they had serious concerns.
