During the AGU Fall Meeting I had the honor of working with Peter Sinclair of Climate Denial Crock of the Week and John Cook of Skeptical Science, interviewing an amazing line-up of scientists and science communicators. I’m floored by who we interviewed and could have a chat with. Everyone brought their A game which gave us some incredible footage (you can find all the videos in the AGU 2014 video archive, they’ll be added as they’re released).
A lot of this footage you’ll also see in the upcoming Massive Online Open Course (MOOC) from The University of Queensland. The Denial101x MOOC will launch in April 2015 on the EdX platform. Registration has opened so you can register for free.
John, Peter, and I managed to get some amazing scientists for this MOOC and our own productions:

Very few Americans are aware of the overwhelming scientific consensus on global warming (Maibach 2013). There’s a huge gap between the agreement the public thinks there is between scientists and the actual agreement among scientists. It’s because of this lack of awareness that several studies investigated what the agreement is among scientists.
When researchers surveyed climate scientists on the cause of global warming 97% of the actively publishing climatologists said that “human activity is a significant contributing factor in changing mean global temperatures” (Doran 2009) Researchers found the same patterns when they analysed public statements of climate experts (Anderegg 2010). When researchers looked into how the scientific consensus on global warming evolved from 1996 to 2009 they found a steady increase in the agreement among scientists (Bray 2010). The latest survey on the scientific literature found that 97% “endorsed the consensus position that humans are causing global warming” (Cook 2013).

The so-called sceptics like Anthony Watts often have some very interesting predictions and speculations about global warming and climate change. Especially the predictions they make when dealing with their opponents can get very strange. The latest example of this was when Anthony Watts noticed a new widget on the Skeptical Science website.
Not much information was present what this widget was about. It had some sort of outline in it and a countdown, but what it was counting down to wasn’t obvious at the time. When you clicked on the widget it directed you to a page full of silhouettes.

Last year Cook et al. released a paper that analysed the scientific consensus on anthropogenic global warming in the peer-reviewed scientific literature.
What they did in that study was look at almost 12,000 abstracts from 1991 to 2011 that matched the search “global climate change” or “global warming.” What they found after analysing these abstracts is that among those that expressed a position on global warming, 97% endorsed the consensus position that humans are causing global warming. They also contacted 8,547 authors to ask if they could rate their own papers and received 1,200 responses. The results for this again found that 97% of the selected papers stated that humans are causing global warming.

Last year Cook et al. released a paper in which they analysed the scientific consensus on anthropogenic global warming based via the peer-reviewed scientific literature.
What they did in that study was examine 11,944 abstracts from 1991 to 2011 that included the words “global climate change” or “global warming” in their abstract. What they found after analysing these abstracts is that among those that expressed a position on global warming, 97% endorsed the consensus position that humans are causing global warming. They also contacted 8,547 authors to ask if they could rate their own papers and received 1,200 responses. The results for this again found that 97% of the selected papers stated that humans are causing global warming.

It’s not often that I fully agree with something that Anthony Watts says, but sometimes it does happen. This time it’s about how you approach those that you are critical about.
One of the things people notice about me is that I focus on the arguments that someone presents and not the person; also known as playing the ball not the man. Of course I’m not perfect but I do make an effort to stay civil in what I write and I expect the same from visitors on my website who leave a comment.
Experience has taught me that not being civil almost always derails any rational exchanges. It can easily result in polarizing both sides more, and can have real negative consequences for readers of your website accepting valid science. When communicating science language matters more than you think.
Anyone familiar with Watts Up With That will have noticed that anything published on it that mentions Skeptical Science often displays a rather obvious dislike for Skeptical Science. Both for the Skeptical Science website and the people who are involved with it.
It shows with the language used and all the attacks on the materials created or used by Skeptical Science. Often it doesn’t really matter if it’s valid criticism as long as it in some way critiques or undermines what was released. Especially when it’s something that is easy to understand and helps with communicating the science behind global warming. Which showed with the attacks towards the Cook et al. paper that measured the scientific consensus on global warming in the scientific literature.
I’ve always liked getting comments with feedback, criticism, or that give interesting commentary. It has helped me learn new things, hone my position, and helps me correct statements. It also acts as a great source for inspiration for new blog posts.
As long as you abide by some simple rules everyone is welcome to engage me on YouTube and my blog. It’s the reason why my comment sections are filled with critical comments and my responses and/or corrections to those comments. I especially appreciate feedback that points out a statement that isn’t correct, because they help me weed out incorrect positions and prevents me from inadvertently spreading incorrect information.
Several months ago Cook et al. released a paper in which they analysed the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature.
What they did in that study is examine 11,944 abstracts from 1991 to 2011 that included the words “global climate change” or “global warming” in their abstract. What they found after analysing these abstracts is that among those that expressed a position on global warming, 97% endorsed the consensus position that humans are causing global warming.
Not a surprising result at all as this was a bigger literature survey than the one done by Oreskes in 2004. It found that all the selected abstracts (928 in total) that stated a position on the cause of global warming said humanity is to blame.

What the Cook et al. paper did was examine 11,944 abstracts from papers that were published from 1991 to 2011 that included the words “global climate change” or “global warming” in their abstract. What they found after analysing these abstracts is that among those that expressed a position on global warming, 97% endorsed the consensus position that humans are causing global warming.
They also contacted 8,547 authors to ask if they could rate their own papers and got 1,200 responses, which meant that 2,142 papers were also rated by their authors on their endorsement level. The results for this again found that 97% of the selected papers stated that humans are causing global warming. This was done to determine that there wasn’t any sort of inherent problem in the rating system used and this seems to indicate that.
