How many scientists agree on climate change

Some commentators have challenged the significance of a scientific consensus, saying it is a distraction from more pressing concerns. However, they say it is important for media organisations to avoid giving a false sense of balance by giving equal weight and coverage to for-and-against arguments.

Most important, a consensus is seen as vital for a concerted international response to the climate crisis. Native American climate activists and allies demonstrating in Washington on 15 October. Many Americans do not accept the science on the climate crisis.

Fiona Harvey Environment correspondent. Reuse this content. Facts Related Climate Images. Info 31, scientists say "no convincing evidence". What is the significance of these statistics? The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind.

There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth. Of those with expertise in climate science: Asked if they regarded global warming as a very serious problem?

By implication, that small number who disagree must be out of the mainstream: cranks, chronic naysayers, or shills of the fossil fuel industry.

The conclusions of the IPCC are the other most often cited support for anthropogenic climate change. These conclusions are consensus results of a committee with thousands of contributors. Although this is often viewed as a monolithic conclusion, the nature of committee processes makes it virtually certain that there are varying degrees of agreement, similar to what was shown in the Bray and von Storch survey.

A consensus on climate change and its human cause exists. Multiple studies published in peer-reviewed scientific journals show that human activities are the primary cause of the observed climate-warming trend over the past century. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position.

The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

There is no alterative explanation supported by convincing evidence. While natural sources of climate variability are significant, multiple lines of evidence indicate that human influences have had an increasingly dominant effect on global climate warming observed since the mid-twentieth century.
