Climate change blogs are blogs whose primary focus is climate change. Some of these blogs are maintained by individuals (e.g., A Few Things Ill Considered--Coby Beck), while others are maintained by groups of people (e.g., RealClimate--10 Climate Scientists). In addition to the blogs exclusively focused on on climate change, there are many environmental and energy centric blogs that include information on climate change. Some of these more general blogs are excellent sources of up-to-date information and commentary on climate change issues.
There are many ways to calculate the significance of a blog, such as page views and unique visitors. "Authority" is one way of calculating the significance of a blog.
1. RealClimate (790) — "Climate science from climate scientists." "RealClimate is a commentary site on climate science by working climate scientists for the interested public and journalists. We aim to provide a quick response to developing stories and provide the context sometimes missing in mainstream commentary. The discussion here is restricted to scientific topics and will not get involved in any political or economic implications of the science. All posts are signed by the author(s), except 'group' posts which are collective efforts from the whole team. This is a moderated forum."
2. A Few Things Ill Considered (3968) — “A layman’s take on the science of global warming featuring a guide on How to Talk to a Climate Sceptic.”2
3. Celsias (5,455) — “Celsias.com helps individuals, companies and organisations do practical things to combat climate change.”3 A (mostly) climate solutions website.As much a news feed as a blog, but both are great.
4. DeSmogBlog (8,454) — “Clearing the PR pollution that clouds climate science.” 4A very good all-around climate blog.
5. Climate Ark (15, 917) — “Climate Change and Global Warming Portal.” 5A good blog and a great news feed.
6. Climate Progress (16,087) — “An insider’s view of climate science, politics, and solutions.” 6A fast-rising (relative) newbie.
7. It’s Getting Hot In Here (20,428) — “Dispatches from the youth climate movement.” 7There is hope for the next generation after all!
8. Climate of Our Future (24,327) — “A discussion on climate change.”8 Another good general interest climate blog.
9. Climate Feedback (34,124) — “An informal forum for debate and commentary on climate science.” 9A useful new blog, sponsored by Nature magazine. On the downside, you’ll have to endure posts by Roger Pielke, Jr.
10. Accuweather Climate Blog (39,249) — “Global warming news, science, myths, articles.” 10A good general interest climate blog.
