Climate Change

Sizable numbers at least partly blame humans
Ahead of more rounds of climate change talks, Gallup finds residents in the top five greenhouse gas-emitting countries are no more knowledgeable about global warming than they were a few years ago. Americans who are aware of climate change are the least likely to blame it on humans.

About half satisfied with efforts to preserve the environment
Gallup surveys show residents in one of the world's fastest growing economies, India, narrowly prioritize environmental protection (45%) over economic growth (35%).

Americans among least likely to attribute to human causes
Thirty-five percent of adults in 111 countries in 2010 say humans cause global warming, while less than half as many (14%) blame nature. Thirteen percent fault both. Americans are the most likely to blame natural causes, setting them apart from the rest of the developed world.

Worldwide, 42% see serious risk, similar to 2007-2008
Gallup surveys in 111 countries in 2010 find 42% of adults worldwide view global warming as a serious threat to themselves and their families, essentially unchanged from 2007-2008. Fewer Americans and Europeans feel threatened by global warming than they did a few years ago.

Fifty-one percent worry a great deal or fair amount, down from 66% in 2008
Americans continue to express less concern about global warming than in the past, with 51% saying they worry a great deal or fair amount about the problem. Less than a majority now believe its effects are already occurring. Americans' attitudes have generally stabilized this year after declining from 2008 to 2010.

Fewer believe climate change results from human activities
Many Australians have recently altered their opinions about the cause of global warming and the gravity of the issue. While the majority still considers climate change a serious matter, fewer say human activities cause it.

Majority make some effort to preserve biodiversity
As millions this World Environment Day reflect on how they can conserve the diversity of life on Earth, a Flash Eurobarometer survey finds more than 9 in 10 adults in the European Union agree that biodiversity loss is a very or fairly serious problem globally.

Americans split more evenly; give energy legislation lowest priority overall
When asked which of three current legislative initiatives Congress should make its highest priority, Democrats favor financial reform, while independents and Republicans choose immigration legislation. Overall, Americans split more evenly between the two, and give a new energy bill lower priority.

Access to quality water relates closely to overall city satisfaction
Gallup-Healthways Well-Being Index data from the largest U.S. metropolitan areas surveyed reveal that more than 90% of residents in all areas report easy access to clean and safe water, ranging from a low of 90.9% in Las Vegas to a high of 97.6% in Portland, Oregon.

Dissatisfaction highest in Middle East and North Africa
Gallup surveys in 153 countries find that one-quarter of the world's adults -- or roughly 1.1 billion people -- are dissatisfied with the quality of air in their communities, ranging from a high of 70% in Hong Kong to a low of 3% in Singapore.
