What percentage of people believe in global warming?

Answer 1

We have no idea how many agree.

A:The AAAS (American Association for the Advancement of Science) boasts about ten million members internationally, including 262 societies and academies of science. That is huge, and probably larger than the number of scientists world wide. A better estimate for the number of scientists and researchers would probably in the neighborhood of 6 million.

Not all of them accept the general consensus of anthropogenic global warming. To estimate that number, we would need a representative poll of scientists, of whom probably fewer than 2000 lay claim to recent specific work in climate science. A survey nearly ten years old indicated 97% out of 1372 climate scientists who responded accepted the consensus, which tallies to 1330 people.

But of scientists in general, the percent would be lower. Many of them would not be aware of specific research, or even all that interested in results far outside their field of expertise. Nevertheless, a poll of general scientists revealed about 80% concurred with the consensus, suggesting the total number of scientists who accept global warming would be approximately 4.6 million.

A:Most scientists and their organizations around the world believe that global warming is happening and it is being caused by human actions,

1. burning fossil fuels and
2. cutting down forests.

Scientific Organizations that accept the broad scientific consensus that global warming is happening include:

• NASA's Goddard Institute for Space Studies in New York
• American Association for the Advancement of Science (AAAS)
• National Research Council
• American Institute of Physics
• European Academy of Sciences and Arts
• European Science Foundation
• The United Nations' Intergovernmental Panel of Climate Change (IPCC)
• American Geophysical Union
• US National Academy of Science
• American Meteorological Association
• American Medical Association
• American Astronomical Society
• Joint Science Academies
• American Meteorological Society
• Network of African Science Academies
• International Union for Quaternary Research
• Australian Coral Reef Society.

Answer 2

According to this 2010 National Academy of Sciences survey, 97-98% of actively publishing climate scientists agree that global warming is happening and it is being caused by human activity.

Check the link below.

A:

Ninety-seven percent of the climate scientists surveyed believe "global average temperatures have increased" during the past century.

Eighty-four percent say they personally believe human-induced warming is occurring, and 74% agree that "currently available scientific evidence" substantiates its occurrence. Only 5% believe that that human activity does not contribute to greenhouse warming; the rest are unsure. These scientists are based all over the world in multiple countries. Many independent groups conduct the research. Almost all of these studies conclude that global warming is happening. While opinions may vary, it is important to note that the vast majority of climate scientists feel that the data points to human activity as the cause.

A:

An extremely high percentage think "global warming" is occurring. A somewhat smaller percentage thinks mankind is chiefly responsible.

But it is important to note that science is not a democracy. So even if 100% thought something was true, it might not be.

Science is done by hypothesis-testing and retesting. But in the case of global warming and mankind's part in it, this is hard to do.

A:

The United Nations-sponsored Intergovernmental Panel on Climate Change (IPCC) is the largest, most reputable peer-reviewed body of climate-change scientists in history. It was formed by the United Nations in 1990 and is composed of the top scientists from around the globe. It employs a decision-by-consensus approach.

It has said repeatedly that human activities have had a "discernible" influence on the global climate and that global warming is a serious problem that must be addressed immediately.

Answer 3

97% of climate scientists concur that humans are the primary contributors to climate change, of which global warming is one factor. Of scientists in general, the percentage drops significantly because climate research is outside the domain of biologists, information scientists, political scientists, and so on. Only 80% (4 out of 5) scientists accept the evidence indicating humans are the primary contributors.

People in general tend to be much less informed, or are widely misinformed. In most educated, industrial countries around the world more than half the population accepts the scientific consensus. Here in the United States, however, popular opinion fell from about 70% in 2008 to under 60% by 2010, but has gradually risen back close to 70% in the past two years, per a Yal/George Mason poll.

In contrast, only 10% of the general public thought it was false in 2008, which doubled to 20% by 2010, but has since declined to nearly 10% again now (late 2012).

Answer 4

Approximately 74% of Americans believe in global warming, according to a survey conducted by the Yale Program on Climate Change Communication. This percentage may vary in different countries and regions.

Answer 5

15%

49% by the latest report are not buying it. 51% still believe it.
