Garry Kasparov: The Price of Inaction in Ukraine

Originally posted on TIME:

There are many questions still to be answered about what happened to Malaysian Air flight MH17 over Eastern Ukraine. I will limit myself to what is known to a reasonable doubt based on the evidence and statements that have been provided by numerous officials in the 36 hours since the tragedy. Nearly 300 innocent lives were lost when flight MH17 was shot out of the sky with a surface-to-air missile. The missile was launched from an area in Eastern Ukraine controlled by Russia-supplied and Russia-supported para-military separatists that include at least some Russian officers and special forces. Three other planes have been shot down in the region in the last month.

Nearly 300 dead. Horribly, needlessly. We all mourn them and seek to understand how this could happen. Based on the day’s official statements and most news coverage the word “blame” is somehow forbidden and I do not understand why…

Diving into the Deeps of Decarbonization

Originally posted on Watts Up With That?:

[UPDATE: Comment from Anthony: There has been a tremendous amount of discussion and dissent on this topic, far more than I ever would have imagined. On one hand some people have said in comments that Willis has completely botched this essay, and the Kaya identity holds true, others are in agreement saying that the way the equation is written, the terms cancel and we end up with CO2=CO2. It would seem that the cancellation of terms is the sort of thing that would rate an "F" in a simple algebra test. But, I think there's room for both views to be right. It seems true that *technically* the terms cancel, but I think the relationship, while maybe not properly technically equated, holds as well. Here is another recent essay that starts with Willis' premise, where CO2=CO2 and expounds from there. See: What is Kaya's equation?

The Beer Identity

Guest Post by Willis Eschenbach

It’s morning here in Reno, and I thought I’d write a bit more about the Kaya Identity and the Beer Identity. My last post about the Kaya Identity was controversial, and I wanted to see if I could clarify my point. On the last thread, a commenter did a good job of laying out the objections to my work:

Sorry but I think you’ve all entirely misunderstood the point of the identity. The Kaya identity is a means of communicating the factors of which CO2 emissions are comprised, in order to explain the physical levers that are available if one wishes to control an economy’s CO2 emissions.

These are analogous to mathematical factors, for e.g. 6 = 3 x 2. This illustrates that 2 and 3 are factors of 6. This doesn’t prove anything mathematically – it’s just an identity. But it is informative nonetheless…

A conversation with Dr. Roger Pielke Jr. on the Kaya Identity

Originally posted on Watts Up With That?:

As many readers know, there was quite a hullaballo over the Kaya Identity last week, two posts by Willis Eschenbach here and here created sides seemingly equally split on whether the equation is useful or not.

One of the most strident critics was Dr. Roger Pielke Jr., and in the spirit of keeping an open mind on the issue, I offered him space on WUWT. Here is my email and his response, reprinted with his explicit permission.

[T]here’s good reason to believe that the self-righteous and contemptuous tone with which the “scientific consensus” point is typically advanced (“assault on reason,” “the debate is over” etc.) deepens polarization.  That’s because “scientific consensus,” when used as a rhetorical bludgeon, predictably excites reciprocally contemptuous and recriminatory responses by those who are being beaten about the head and neck with it. – Dan Kahan
