The class “Climate Science for Climate Activists” I have taught for the last 6 or so weeks is now completed. The slides are available here.
I am planning to teach a course by this title online using the Zoom platform. I have a half dozen or so expressions of interest, but I wanted to put the outline up and in a place that can be … Continue reading
On Sunday, 11th February 2018, I presented an Abstract of a 3 hour talk on the subject, “Carbon emissions and climate: Where do we stand, and what can be done if it all goes wrong?” at the Needham Lyceum, hosted … Continue reading
I spent a bit of last week at a symposium honoring the work of Charney and Lorenz in fluid dynamics. I am no serious student of fluid dynamics. I have a friend, Klaus, an engineer, who is, and makes a … Continue reading
Dr Neil deGrasse Tyson. I think he’s awesome. Marvelous. I saw him in Boston. He and I did not get off well, at the start, because of my being awestruck, and feeling very awkward, and the short time we had … Continue reading

Response to a paper by Hermann Harde, from Ken Rice at … And Then There’s Physics. Dr Rice cites two other responses as well: One by Gavin Schmidt at RealClimate. One from 2011 by Gavin Cawley from the University of … Continue reading
I have made an important update to an earlier post here, Getting back to 350 ppm CO2: You can’t go home again. The message, essentially based upon recent work Tokarska and Zickfield on one hand, and by The Global Carbon … 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…
With regard to my comment at hypergeometric | July 13, 2016 at 3:50 pm on Tamino’s blog, someone challenged me on my assertion “Believe me, the +3C-+4C worlds are not places we want to go!” there. I have replied at … Continue reading
Professor Kevin Anderson on Techno Utopias. The Paris “COP21” agreement is/was not only expecting miracles, it was counting on them. Y’think climate disruption causes ecosystem disruption: Try geoengineering. Well the answer was simple. If we choose to continue our love … Continue reading
Click the image above to see a video from the GFDL CM2.6 climate model. This is NOT this year’s El Nino. When you start a climate model in which the ocean and the land and atmosphere can inte… Source: El … Continue reading
Good to review the basics once again. Professors Dave Archer and Ray Pierrehumbert do, in my opinion, some of the best introductions: Infrared radiation and planetary temperature.

Incredible Rainfall In South Carolina, and Yes Climate Played A Role – Dan’s Wild Wild Science Journal – AGU Blogosphere
Make no mistake, this was a flood event unlike any other in South Carolina and while Hurricane Joaquin never hit the coast, it holds a smoking gun. This flood was the result of several factors, an … Source: Incredible Rainfall … Continue reading
“A very short history of climate change research“, by Alice Bell. The story of scientists discovering climate change is longer than many of us tend to imagine. We’ve had a sense that what humans do might effect the climate since … Continue reading
“There is such a thing as being too late.”
(Updated below, 21st June 2018.) Zeke Hausfather published “Climate Impacts of Coal and Natural Gas” on the BEST project site. He makes a close analysis of the relative benefits of coal and natural gas, considering the subtleties and pitfalls of … Continue reading
Professor Richard D Schwartz wrote, in 2012, a nice article succinctly summarizing the scientific basis for climate change and global warming. Called “An astrophysicist looks at global warming”, he pithily summarized: “Greenhouse gas” warming occurs because the collisional de-excitation time … Continue reading

Love the “But I digress” in Tamino‘s post “NASA and NOAA” about new global temperature series from both agencies. Tamino references this lecture by the middle-of-the-road climate scientist and hurricanes expert Professor Kerry Emanuel:

Kevin Jones asked me if I could put the links in a Comment on a post I made at Google+ in a collection or something for reference. I am therefore repeating the Comment with these details below. No one simple … Continue reading
Why decentralized electrical power has to win, no matter what Elon Musk says, and utilities are doomed
Jonah Bloch-Johnson, Ray Pierrehumbert, and Dorian Abbot have a new paper out in Geophysical Research Letters which is pretty exciting, at least for me, having to do with both climate and dynamical systems. They are far from the only ones … Continue reading
One of the “climate zombies” that get’s trotted out from time to time and at places on the Internet is the argument of Knut Ångström, trying to rebut the calculations of Svante Arrhenius regarding the impact a doubling of carbon … Continue reading
