Climate Feedback
Climate Feedback is a site on which scientists grade articles about climate science. Not only do they provide comments, they also give a final grade, indicating the scientific credibility. For example, Chris Mooney’s article on what we’re doing to the … Continue reading

Airborne fraction
Given the recent news that the rise in CO2 has greened the planet, I can see a new “skeptic” meme appearing. Essentially, I can see them arguing that both climate sensitivity is too high, and that nature will take up … Continue reading
Matt Ridley doesn’t understand free speech
Matt Ridley is, once again, complaining that the climate change lobby wants to kill free speech (you can read it here). What it mainly seems to illustrate is that Matt Ridley doesn’t really understand the concept of free speech. One … Continue reading

Consensus on consensus
Richard Tol’s consensus paper has finally been published. Richard’s paper can probably be described as taking all possible sets of numbers from all the various other consensus studies, and plotting graphs showing various possible levels of consensus, but without paying … Continue reading
Climate targets
Oliver Geden is a climate/energy policy analyst at the German Institute for International and Security Affairs. I’ve written before about Oliver Geden’s views and have, typically, been rather unimpressed by what he presents. He’s even accussed me of misrepresenting him, … Continue reading

Physics
One of the nice things about physics (well, I like it) is that you can often quantify things by making basic back-of-the-envelope calculations. Maybe a classic example of this is David MacKay’s book about renewable energy called Sustainable energy – … Continue reading →
