This is a list of the ranking of the main climate blogs based on Alexa. The sites were collected from those linked to by some of the main blogs as well as Realclimate. Please note, I have only given sites with a ranking and Alexa only give statistics for sites which have separate URLs, which means some sites are not listed. This affects several on Scienceblogs.com.
The list was correct as of 15th December. If I have missed any please feel free to add to comments.
**Slant: Where possible, I’ve used the description given with the link. However, where a description was not given, I’ve quickly looked to see. These could be wrong – if you spot any please add a comment.

Corrections
- I had assumed Alexa was ranking using URL so that planetgore.nationalreview.com was different from nationalreview.com. This does not appear to be the case, so I do not know how Alexa decides when a site is listed separately. WordPress blogs certainly are each given their own ranking.
- It had not twigged that I was using an old Bishop Hill site address. For consistency (with another blog that changed) I will just give the new address as that has the higher count.
- After Anthony’s comment (2013/12/15 at 5:40 pm), I’ve adjusted the Blackboard to “Lukewarmer”. I will also update the spreadsheet.
- After Anthony’s comment (2013/12/15 at 5:43 pm I have added in hotwhopper (@37) as well as Bishop Hill’s old site (@12) and scef.org.uk(116) (Relevant spreadsheet: listofsites3
- After Derek’s post at 2013/12/15 at 7:10 pm I’ve added http://www.principia-scientific.org/ and http://www.globalwarmingskeptics.info/index.php spreasheet now at listofsites4
- After pgosselin’s comment December 15, 2013 at 7:13 pm‘s comment EIKE, Science Skeptical and Klimazwiebel added to list. Spreadsheet at listofsites5
- Another suggestion from pgosselin & Climate Scam is in at 46.
- The list of unlisted tables listed below
- SkepticalScience AGW->Warmist

Others sites
These sites either aren’t listed in Alexa or they are not counted separately

Planet Gore doesn’t post every day and has relatively few comments. By what methodolgy does Alexis rank it ahead of WUWT?
You are quite right … it is giving the ranking for national reveiw
Have you adjusted for those sites that have alternate addys? eg I only recently changed my bookmark for Bishop Hill. Is the score for National Review or for Planet Gore? I’ve found it hard to get stats for sites that are nested withing something else. eg Think Progress is the new home of Climate Progress. I also find it hard to believe Harmless Sky has featured so high given how few posts I can see.
However, well done for getting so high up the list. One of the features of the top sites is regularity of blogs and good discussions amongst posters.
What I did was to take the name and URL on several sites and to compile a list of blogs and then go to Alexis and rank them all. It was obvious that most of the top ones were just minor pages in a well known site (like the BBC). So I removed all these and searched for other ones by checking those sites not listed by the domain name, particularly where it had a url of the form: “domain.com/blogs/Anotherblogsite” and/or urls where alexis was giving the same ranking.
As far as I could see Alexis was giving different ranks to sites with URLs such as “Anotherblogsite.domain.com”.
Unfortunately I now have to go Xmas shopping. So, I’ve now added a link to the spreadsheet I used at the end of the post.
Following on from TinyCO2’s comment at 11:18, your spreadsheet shows you have ranked http://www.bishophill.squarespace.com/, which is the old address for the Bishop Hill blog and which still links through to the new one. That site is ranked 93,239 worldwide by Alexa. The new Bishop Hill blog address is http://www.bishop-hill.net, which is ranked 86,936 worldwide. I’ve no idea how you combine these two figure to give a true ranking – over to the experts. 🙂
Thanks Bob. Yes you are right the address has changed. I’ve now updated the spreadsheet and the table to reflect this. I did consider putting both sites on, but I think Tallbloke might feel a bit squashed in by bishops as the two sites would be 10 & 12 with tallbloke pushed out of the top 10 to 11.
So, I’ve just included the new Bishop Hill which is higher.
Thanks. I’d categorize The Blackboard as Lukewarmer.
Also, you might what to include the lunatic fringe blog known as “hotwhopper”…guessing it will come out somewhere near Planet 3.0 or maybe ahead a bit.
Thanks, I’ve updated the list and spreadsheet.
No mention of
http://www.principia-scientific.org/
or,
http://www.globalwarmingskeptics.info/index.php
?
thanks now updated.
Thank you. Good to know.
Great job!
But Please add EIKE, Science Skeptical and Klimazwiebel to your list. These are quite important in Germany…especially Klimazwiebel because it is most often in English. Or did I miss it on your list.
I found it….sorry. I’d classify Klimazwiebel as a warm luke-warmist site. 🙂
There’s something odd with klimazwiebel as it has two web address:-
http://klimazwiebel.blogspot.com/
http://klimazwiebel.blogspot.co.uk
As far as I know Google (blogspot), redirects / bounces to what it think is the viewer’s local region.
If not on your list, also the Climate Scam in Sweden (skeptic)
thanks, it’s now added at 46
Yes, and ‘The Climate Scam’ is the old name. Changed quite some time ago to:
http://www.klimatupplysningen.se/
But the old URL still works.
(Don’t know it this alters the ranking)
Thanks for doing this, Mike. I must say that I was quite pleasantly surprised to see my quiet little corner of the blogosphere much higher on the list than I would have expected it to be 🙂
When assigning ‘sceptic’, ‘lukewarmer’ or whatever, I wonder what level of warming separates each group? I would settle for 1.2C for a doubling of CO2 until I get serious evidence it’s something else but I’d call myself sceptic (or even denier) because I reject the edifice of lies, greed and stupidity built upon the issue. Can the different groups be divided by numbers or is it more of a state of mind thing?
Outstanding list, thanks, been looking for this everywhere! Was kinda curious to see if my site was there, but I guess I don’t post on climate issues enough.
Planetary Vision looks a good site but unfortunately it isn’t ranked by Alexa. However, I’ve now added the “list of unlisted” sites and added it to the spread sheet.
Interesting, bit of a fringe blog. Thanks.
Reblogged this on CACA.
Another omission is http://www.climate-resistance.org/ which is pitched more at the philosophy/politics side than examining the science. As a result I find it difficult to classify as sceptic versus lukewarmer.
Thanks, but they are there at number 109!
Oops sorry
However, I would definitely label SkepticalScience as ‘warmist’ and very strident at that …
(Why the label ‘AGW’ for that one blog only?)
It is a mistake. I think they started in a slightly different category and I missed it when I updated the categorisation.
As far as I can see, John Cook’s SkS is the only ‘AGW’ site. Is that a particularly bonkers version of ‘warmist’?
That is literally the explanation (I think). Although it was entirely a mistake. Originally SkepticalScience was taken from WUWT where it was “sent to the corner of the room for being naughty” and had its own special category.
So, when I changed the others to “Warmist” it was missed. I think I must have just removed the long “they’ve been naughty” bit from the categorisation and forgot to change the AGW to warmist.

Interesting list, thanks. Noticed a couple of small issues:
– Climate Realists is listed twice (with/without index.html in the link)
– AFAIK The Science of Doom is purely a science site, so is only ‘sceptic’ in the sense that it lacks the political spin of a typical warmist site, though such objectivity tends to favour the (lukewarm) sceptic case of course.
Another thing: I have read Harmless Sky on occasion but good though it is was surprised to see it at #3 in the rankings. I just had another look and given how infrequent the posts are it now seems likely that there is some sort of mistake. Perhaps the ranking is for all blogs on plus.com?
John in Oz leaves this comment on WUWT
An interesting graphic of web site popularity appears at http://nmap.org/favicon/ which was produced by scanning the top million web sites for 2013 (as ranked by the analytics company Alexa).
The downloadable file with all of the sites listed has WUWT ranked as 28,232.
For comparison:
Realclimate – 157,676
Bishop Hill – 297,496
Tamino – 335,757
Judith Curry – 477,404
As the search engine, social media and porn sites will take up most of the higher hit-count sites, this seems to be a very creditable result for WUWT. Congrats Anthony and the team.

This page has been a handy reference. At times, useful as a reality check to “consensus” alarmists!
If there’s room for another sceptic site on the next update : http://climatism.wordpress.com/
