AGW, Considered as a Black Swan
In my previous post I took issue with Lovejoy's claim to show, by statistical analysis of global temperature data since 1500, that the probability that natural processes would produce the amount of warming observed in the period 1880 to 2008 was less, proba...

Of some general interest.
Daniele Fanellis' study claimed to be the first meta-analysis of surveys asking scientists about their experiences of misconduct. It found that, on average: About 2% of scientists admitted to have ...

Do you think PLOS's pay-to-publish business model says anything about the quality of the work they publish?  I am unfamiliar with their journals, but they have over 5000 people on their editorial board, which struck me as odd.

Ocean Warming Data
I have several times seen the claim that, despite the apparent pause in surface temperatures, global warming is actually going faster than ever, with the missing heat in the ocean. So far I have seen no support for that claim. I did, however, recently come ...

Climate Nuts vs the IPCC
In one recent climate thread on Google+, I was informed, by three different people, that global warming would: Create two billion climate refugees Flood most of the world's large cities Destroy civilization. The simplest rebuttal to such claims is the lates...

not in this thread, no. I prefer to enjoy the "climate nuts vs the IPCC" bit.

Dealing with Climate Change: Prevention vs Adaptation
Suppose you believe, as many people do, that climate change due to anthropogenic CO2 is a serious problem. There are two different ways you might try to deal with it. One is by trying to keep it from happening, or at least to slow it. The other is by adapti...

Two Problems With the 1% Claim
A number of recent news stories claim that a recent paper by Lovejoy proves that the probability that the warming of the past century is entirely due to natural causes is less than one percent. I find the conclusion plausible enough, but, so far as I can te...

+David Schneider-Joseph I've just expanded my response to your question into another blog post, pointing out that AGW itself is a black swan—a cause of rapid warming whose probability could not be predicted by analyzing past climate data, since it was produced by a different mechanism.

Another Critic of Cook et. al. 2013
Readers will be familiar with my critique of Cook et al. 2013, an article widely cited as showing that 97% of climate researchers support "the consensus position." I have just come across a much more detailed criticism of the paper on other grounds, by some...

Bits From the Latest IPCC Report
(all quotes from the summary for policymakers)

"In this report, the term impacts is used primarily to refer to the effects on natural and human systems of extreme weather and climate events and of climate change"

Energy is all about economics. If the State dictates based on political/ideology or other non economic function, business will not buy it. While I tend towards green energy, cost is always paramount. One can debate warming, cooling, weather change, whatever until the cows quit farting; but if it costs more to power commerce, with whatever green product is promoted, businesses can't justify it.

Since everyone else seems to be plugging books today, I'll plug three of mine, at one post each.
My second novel has been up on Amazon for a while as a Kindle. It's a fantasy set about forty years after the magical equivalent of Newton, the mage who has taken the first big step towards converting magic from a craft to a science. It also has two love stories which sneaked into the plot when I wasn't looking.
No plot survives contact with the characters.
