Bart Verheggen: Scientists’ Views about Attribution of Global Warming

Ventures Into Scepticism

Real Sceptic has its origins as a companion site for the videos produced by Collin Maessen. The site has progressed beyond this original purpose and now predominantly includes articles that are independent of the content released on YouTube. However this original content is still an important part of the site.

This page serves as an archive for videos produced and released on YouTube. You can find full transcripts, source listing and used media files for the videos. We are currently in the process of transcribing all the audio.

Please note that the first nine videos are of a substantial lower quality than videos that were produced after these. As these first nine videos were as much, and in some case more, about learning to edit videos and learning how to tell a story in sound and images.

Video description

Less than 10% of Americans are aware that there's an overwhelming consensus on global warming. There's a huge gap between the agreement the public thinks there is between scientists and the actual agreement among scientists. Due to the importance of this lack of awareness several studies investigated the agreement among scientists. One of the latest papers studying this was Scientists’ Views about Attribution of Global Warming by Bart Verheggen. Verheggen surveyed over 1,800 scientists and found that a large majority of climate scientists agree that anthropogenic greenhouse gases are the dominant cause of global warming. In this interview Verheggen talks about the results they found and their meaning.
