Climate science is a massively interdisciplinary field with different areas understood to varying degrees. One area that has been well understood for decades is the fundamental fact that humans are causing global warming. The greenhouse effect has been understood since the 1800s, and subsequent research has refined our understanding of the impact of increased concentrations of greenhouse gases on the planet. Also increasing has been the consensus among the world’s climate scientists that the basic principles of anthropogenic global warming (AGW) are correct. This has been demonstrated by multiple reinforcing studies that the consensus of scientists on the basic tenets of AGW is nearly unanimous. Nevertheless, the general public in many countries remains unconvinced not only of the existence of AGW, but also of the degree of scientific consensus. Additionally, there remain a few high-profile scientists who have continued to put forth alternative explanations for observed climatic changes across the globe. Here, we summarize research on the degree of agreement amongst scientists and we assess the quality of scholarship from the contrarian scientists. Many major contrarian arguments against mainstream thinking have been strongly challenged and criticized in the scientific literature; significant flaws have often been found. The same fate has not befallen the prominent consensus studies.
The paper is behind a pay wall but one of my co-authors, Dana Nuccitelli, has a good summary posted at The Guardian.
The full statement has been signed by 520 global scientists from 44 countries.
Earth is rapidly approaching a tipping point. Human impacts are causing alarming levels of harm to our planet. As scientists who study the interaction of people with the rest of the biosphere using a wide range of approaches, we agree that the evidence that humans are damaging their ecological life-support systems is overwhelming.
We further agree that, based on the best scientific information available, human quality of life will suffer substantial degradation by the year 2050 if we continue on our current path.
