FACT: 97% of publishing climate scientists believe humans are causing global warming.
CRAP:
@LouderVol thinks he knows more about climate science than publishing climate scientists.
Here’s a summary of what climate science research and scientific organizations have found about
how many climate scientists accept that humans are causing global warming:
Scientific consensus among climate scientists
~97% of actively publishing climate scientists agree that humans are causing global warming.
This figure comes from multiple analyses of the peer-reviewed scientific literature showing that of the papers
that take a position on the cause of warming, about
97% endorse the view that most recent warming is human-caused. (

Some key points about this consensus:
- A 2013 study analyzing thousands of climate science papers found around 97.1% of those expressing a view agreed that humans are causing global warming. (NASA Science)
- Broader reviews of scientific literature through 2020 found that well over 99% of peer-reviewed studies do not reject human-caused climate change (e.g., a >99.9% agreement in one large survey of ~88,000 papers). (Cornell CALS)
- When surveys focus on climate scientists actively publishing in the field, the agreement typically clusters around 97–98%, and consensus increases with level of expertise. (Yale Climate Communication)
Different methods and definitions (e.g., whether you count all papers or only those that explicitly state a position) produce a range, but virtually all rigorous studies show
a very high level of agreement.
Scientific organizations’ positions
Virtually every major scientific organization that has issued a climate position statement agrees that:
- Climate warming is happening.
- Human activities are the dominant cause of recent warming.
Examples include:
- NASA: states that about 97% of climate scientists agree humans are causing climate change, and that leading scientific bodies worldwide support this conclusion. (NASA Science)
- The American Association for the Advancement of Science, American Geophysical Union, American Chemical Society, and other national academies acknowledge human influence as the primary driver of recent warming. (NASA Science)
- The Intergovernmental Panel on Climate Change (IPCC)—a global body coordinated by the UN—concludes with high confidence that most of the recent warming is due to human emissions of greenhouse gases. (United Nations)
Summary statistics
| Group surveyed | Approximate agreement that humans are causing warming |
|---|
| Actively publishing climate scientists (peer-reviewed literature analyses) | ~97% consensus (NASA Science) |
| Large reviews of published studies overall | >99% of studies do not reject human causation (Cornell CALS) |
| Major scientific organizations globally | Essentially all endorse human influence as primary cause (NASA Science) |
Interpretation
- Climate science expert surveys and literature analyses consistently show an extremely high level of agreement (often quoted as “~97%” or higher) among climate scientists that recent global warming is largely caused by human activities. (NASA Science)
- Leading scientific bodies worldwide endorse this conclusion as the consensus view of climate science. (United Nations)
