I recently noted that there are reasons to think that the effects of human caused climate change are coming on faster than previously expected. Since I wrote that (in late January) even more evidence has come along, so I thought it was time for an update. First a bit of perspective. Scientists have known for…

I see no evidence here that warming is getting worse, especially when you subtract the 2015-2020 "data" (there are none of course) from the end of the graft, which strangely shows a strong climb. The overall temperature trends goes up and down and sideways, showing a fairly linear increase throughout the last century.  Perplexing to me, this is probably caused by CO2 increasing linearly during the same span, although our emissions have been rising exponentially.  At any rate, the actual data give little cause to think the actual trends should change, and if we can't explain and quantify this then it is hard to have confidence in any models predicting imminent changes.  I've yet to hear any climatologists even address this anomaly, let alone explain it.  Now we might just be on the flat side of an exponential curve, but I'd like reasons to think so, not manufactured "data" to frighten me.

*Comparing models and empirical estimates Part II: interview with Brown*


I recently posted an overview of a new climate study, Comparing the model-simulated global warming signal to observations using empirical estimates of unforced noise, by Patrick T. Brown, Wenhong Li, Eugene C. Cordero & Steven A. Mauget. That study is potentially important because of what it says about how to interpret the available data on global warming caused by human generated greenhouse gas pollution. Also, the since publication the study has been rather abused by climate contrarians who chose to interpret it very inaccurately. This is addressed in this item by Media Matters.

My post on the paper describes the basic findings, but at the time I wrote that, I had a number of questions for the study authors. I sent the questions off noting that there was not a big hurry to get back to me, since the climate wasn’t going anywhere any time soon. Lead Author, Patrick Brown, in the mean time, underwent something of a trial by fire when the denialosphere went nuts in the effort to misinterpret the study’s results. I guess I can’t blame them. There is no actual science to grab on to in the effort to deny the reality or importance of anthropogenic climate change, so why not just make stuff up?

Anyway, Patrick Brown addressed all the questions I sent him, and I thought the best way to present this information is as a straight forward interview. As follows.

Amidst the reactions I’ve seen on social media, blogs, etc. to your paper, I see the idea that your study suggests a downward shift in the (severity of, literally, GMT) resulting from greenhouse gas pollution than what was previously thought. However, I don’t think your paper actually says that. Can you comment?

A group of scientists attending a major conference get together in a bar. They talk, but they agree on nothing because they are critical academics. The server comes along to take the beer order and says, “I noticed you all are constantly arguing. What are you arguing about?”

“Sensitivity,” one of them says. “It is the number of degrees C the Earth’s surface will warm with a doubling of CO2 in the atmosphere. Is it 2, 3, 4? … We cant settle on a number”

The server considers their plight for a moment. Suddenly, she rips several sheets out of her order book and hands one to each of the scientists. She notices they all already have pens and mechanical pencils in their shirt pockets.

“Each of you write down a number for sensitivity. Don’t share. I’ll look at them all and if they are all the same number I’ll bring you your beer for free for the rest of the evening.”

The scientists comply. She looks at their numbers. They are all the same. Despite the quibbling they all had the same sense for what the number for climate “sensitivity” likely is. They get free beer for the evening.

Scientific consensus is what most scientists will nitpick about but ultimately agree on if free beer is at stake.

Remember the last Olympics, during the parade, where instead of seeing the athletes march along grouped by country, we saw unidentifiable people who were all either taking selfies or grabbing videos of everything going on around them, but we couldn’t tell who they were because their cell phones were totally covering their faces? These days…

Calbuco is a volcano in southern Chile. This one erupts fairly frequently averaging about every 20 years, sometimes quite impresively. The largest eruption during historic times in Chile occurred at Calbuco in 1894. It is erupting now. Evacuations have been ordered. Here is some amazing footage:

Review of the new, forthcoming 2nd edition, and an interview with author Michael Mann: http://scienceblogs.com/gregladen/2015/04/30/dire-predictions-understanding-climate-change-must-read-book/
Dire Predictions: Understanding Global Warming by Michael Mann and Lee Kump is everyperson’s guide to the latest Intergovernmental Panel on Climate Change (IPCC) report. The IPCC issues a periodic set of reports on the state of global climate change, and has been doing so for almost two decades. It is a massive undertaking and few…

I have often wondered if one of the motives for attempting to deny climate change is their denial of responsibility. I expect energy companies are actively taking profits out of the corporation so there will be no assets to attach.

As we stood in Abdul's cinder block walled concrete slab office at the very end of the main avenue in town, negotiating terms for Scotch and tobacco, Hamisi stormed into the room furious.  "I just fired Muzenda, that worthless mechanic," he was saying. "For a Muslim he sure does drink a lot, and more so when he is on the job. I'm giving him his severance pay now," he continued, pawing at the contents of the cash drawer, which he had just opened.  Hamisi stormed out with the cash in hand, with Naipaul staring close behind.   

And just at that moment, Abdul's countenance visibly changed.  He turned relatively white for a brown man, and I swear on the heavens that I saw a glow in his eyes.  I don't mean a metaphorical glow.  I saw light come from his very eyes, like dim flashlights, at the same time a profuse sweat formed on his brow and he began to sway a little. 

The sweat dripped into his eyes and seemed to extinguish the preternatural fire they emitted and just as suddenly he came to, or almost came to, and uttered in the darkest monotone, "Hamisi will meet you on the mountains..."  After a moment of silence, he returned to his normally pleasant jovial self, and glancing thoughtfully at each of us in turn, bid us our farewell and a safe journey.  
His last words were this: "Take the case of liquor.  Pay me later if you make it back."

Sungudogo a novel by Greg Laden Sungudogo is a little known zoological mystery, an “undiscovered” primate living in the remote and rugged region of the eastern Congo, where the Central African Rain Forest fringes the high walls of the western edge of the Great Rift Valley. Sometimes called the “fourth African ape,” Sungudogo is not a Gorilla, not a Chimpanzee, not a Bonobo, and possibly not even real. Years ago, Sungudogo drew the interest of th...

That is a good question, and difficult to answer. If it turns out to be, it will be the warmest calendar year in the instrumental record, which goes back into the 19th century. Regardless of what El Nino (ENSO) does, 2015 will be a warm year. Why? Because everything is warm and getting warmer and…

I once knew a young woman who was in high school and shall remain nameless. One day I picked her up at school to drive her home, and asked how she was doing. “Depressed, actually,” she said. “Why, did something go wrong at school?” “Kinda,” she replied. “The social studies teacher was out today.” “That’s…

Introduction
I write about evolution, other areas of biology, climate change, archaeology, and related topics.  I blog at Scienceblogs, 10,000 Birds, and a few other places.  I wrote a novella about the search for an elusive and strange primate in Africa, called Sungudogo (available on Amazon and elsewhere as an eBook).
