You are correct.....only 97% it seems.
The overwhelming majority of climate scientists agree that climate change is real and primarily caused by human activities, particularly the burning of fossil fuels. This scientific consensus has been well-established through multiple studies and surveys over the years. Here are some key points regarding the proportion of climate scientists who believe in human-caused climate change:
1. Consensus Among Scientists
• 97% Agreement: Multiple studies, including one published in the journal Environmental Research Letters (Cook et al., 2013), have shown that around 97% of climate scientists agree that climate change is happening and that human activities, particularly the emission of greenhouse gases like carbon dioxide, are the primary cause.
• National and International Scientific Bodies: Leading scientific organizations around the world, such as the Intergovernmental Panel on Climate Change (IPCC), the American Association for the Advancement of Science (AAAS), and the National Aeronautics and Space Administration (NASA), all affirm that human-caused climate change is occurring.
2. Scientific Studies on Consensus
• In addition to Cook et al. (2013), other studies have analyzed the scientific literature on climate change, finding similar levels of consensus. For instance, a 2016 study by The Consensus Project analyzed over 11,000 peer-reviewed papers and concluded that over 97% of the studies that took a position on the cause of climate change agreed that it is primarily driven by human activity.
• A 2019 review of surveys and studies published in the journal Nature also reaffirmed this high level of consensus among climate scientists, showing that the 97% figure holds consistently across multiple methodologies.
3. Ongoing Research
• While the details of climate impacts, timing, and feedback mechanisms continue to be researched, the basic understanding that the Earth’s climate is warming due to human activities is firmly accepted by the vast majority of climate experts.
In summary, approximately 97% of climate scientists believe that climate change is real and primarily driven by human activities, a consensus backed by numerous studies and endorsements from scientific organizations worldwide.
