Climate Feedback

Posted on April 29, 2016 by ...and Then There's Physics

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

Posted on April 28, 2016 by ...and Then There's Physics

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

Posted on April 26, 2016 by ...and Then There's Physics

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 →

The TCR-to-ECS ratio

Posted on April 24, 2016 by ...and Then There's Physics

Something I’ve been interested in is whether or not the ratio between the Transient Climate Response (TCR) and the Equilibrium Climate Sensitivity (ECS) best estimates from most of Nic Lewis’s work makes sense. Typically his TCR best estimate is around … Continue reading →

We can never “know” anything

Posted on April 18, 2016 by ...and Then There's Physics

Judith Curry has waded into the consensus discussion by highlighting a post written by two people I’ve never heard of and – from what I can find – have no actual expertise in this topic whatsoever. Apparently the key point … Continue reading →

Time dependent feedbacks

Posted on April 17, 2016 by ...and Then There's Physics

There’s a very interesting new paper by Gregory and Andrews called Variation in climate sensitivity and feedback parameters during the historical period. The motivation seems to be to try and reconcile why estimates of the effective climate sensitivity using recent … Continue reading →

Three years!

Posted on April 14, 2016 by ...and Then There's Physics

Yesterday was the third anniversary of me starting this blog. I was going to post something yesterday, but it coincided with the release of our consensus on consensus paper, which seemed like it should take precedence. It’s been a very … Continue reading →

Consensus on consensus

Posted on April 13, 2016 by ...and Then There's Physics

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

Posted on April 10, 2016 by ...and Then There's Physics

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

Posted on April 9, 2016 by ...and Then There's 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 →
