There is an excellent piece in Ars Technica about why scientific measurements need to be adjusted, and the implications of this for climate data. It is written by Scott K Johnson and is called “Thorough, not thoroughly fabricated: The truth … Continue reading
From WGBH, and hat tip to Environmental Justice TV, includes Dr Gavin Schmidt speaking, who I was especially interested in, and whose talk begins here: Interesting that Dr Schmidt has some gentle criticism of the PBS program NOVA. Whole talk … Continue reading
When knowledge conquered fear … And, what better way to celebrate than watching the National Geographic Cosmos episode, When knowledge conquered fear, hosted by the great Dr Neil deGrasse Tyson, Director of the Hayden Planetarium in New York City.
(Major update of this piece included below.) You can’t. It’ll cost much more than 23 times 40 times the Gross World Product to do it. And, in any case, you need to go to where you need to be to … Continue reading
Just a couple of things to write about The Obvious. I have written a couple of longer thoughts as Comments, here and here, at … And Then There’s Physics. I reiterate that I don’t believe any voter was hoodwinked, that … Continue reading
Hint: Climate change has somethin’ to do with it. Schematic diagram illustrating the component parts of the AMOC and the 26◦ N observing system. Black arrows represent the Ekman transport (predominantly northward). Red arrows illustrate the circulation of warm waters … Continue reading
As previously posted here, people along coasts and their governments, are failing to learn the lessons of both climate-induced sea level rise, and storms like Extratropical Sandy. Now, it’s startlingly clear how ignorant people are of these necessary lessons. The … Continue reading
(Image courtesy of the Damien Garcia.) As a statistician and quant, I’ve thought hard about that oft-cited Boxism. I’m not sure I agree. It’s not that there is such a thing as a perfect model, or correct model, whatever in … Continue reading
Hat tip to And then there’s Physics …: On climate change and Astrobiology , by Adam Frank.
Dr Schmidt is essentially betting that the trend, seen as a random variable, will regress towards the smooth mean. I have a post at Nate Silver’s 538 site on how we can predict annual surface temperature anomalies based on El … Continue reading

Carbon Sinks in Crisis — It Looks Like the World’s Largest Rainforest is Starting to Bleed Greenhouse Gasses
Originally posted on robertscribbler:
Back in 2005, and again in 2010, the vast Amazon rainforest, which has been aptly described as the world’s lungs, briefly lost its ability to take in atmospheric carbon dioxide. Its drought-stressed trees were not growing…
I’m currently studying random walk and diffusion processes and their connections with random fields. I’m interested in this because at the core of dynamic linear models, Kalman filters, and state-space methods there is a random walk in a parameter space. … Continue reading
This is a re-blog of an excellent post at And Then There’s Physics, titled Full-depth OHC or, expanded, “full-depth ocean heat content”. Since my holiday is now over, I thought I might briefly comment on a recent paper by Cheng … Continue reading
Now, more than ever. (The above was published in September 2015.)
One of the best presentations on what can happen if someone takes a naive approach to network data. It also highlights what is, to my mind, the greatly underappreciated t-distribution, which is typically only used in connection with frequentist Student … Continue reading
From time to time, I engage with science deniers on the Web, typically in Comment sections, and primarily regarding aspects of climate science or physics. Some think this to be a waste of time, but, as I enjoy debating (have … Continue reading
From Dr James Hansen’s blog, of today. So, Mr. Buffett, I am heartened by the words in your last annual report, where you conclude that continued inaction on climate change “is foolhardy.” You wrote: “Call this Noah’s Law: If an … Continue reading
Yeah, how about warming up the seas a bit more by building pipelines, buying into more explosive methane (*), and encouraging fracked gas people to export? What could it hurt? There are many alternatives, most sketched here on this blog. … Continue reading

“Welcome to the rest of our lives …” Peter Sinclair speculates 2016 will be as bad and possibly worse than 2012.
From this post: There is a cute little number called Loschmidt, the number of molecules in a cubic meter of air at 1 atm and 0° C, 2.6867774(47) x 1025 molecules/m3 … Eli Rabett provides a neat way to see … Continue reading
Dr Ricky Rood is a professor at the University of Michigan, both a meteorologist and climate scientist, and a regular contributor to the climate and weather blogs at Weather Underground. In a post from April 6th (titled “No Way to … Continue reading
(Clarifying language added 4 Apr 2016, 12:26 EDT.) I just watched an episode from the last season of Star Trek: The Next Generation entitled “Force of Nature.” As anyone who pays the least attention to this blog knows, opposing human … Continue reading
Postscript, 2nd April 2016 I’ve been asked offline whether I buy McPherson’s catastrophic warming scenario. I don’t, or at least I wouldn’t bet on it. Each of the components of Professor McPherson’s scenario are based upon solid science. But in … Continue reading
Update: 20th June 2016 “Rising seas: Should I say or should I go?“, by Delavane Diaz WunderBlog.
Happy Vernal Equinox! This post has been updated today with some of the equations which correspond to the models. An assessment of whether or not there was a meaningful slowdown or “hiatus” in global warming, was recently discussed by Tamino … Continue reading
Twila Moon, University of Oregon, and, soon, University of Bristol, “Face to face with climate change, in Greenland”. Her research concerns ice interface dynamics, principally concerning glaciers.
