For that matter, McGeorge Bundy was a JFK/LBJ administration staffer involved with the Viet Nam war.

Al Bundy was the protagonist of an American sitcom, "Married with Children," from a couple of decades ago. Ted Bundy, of course, was a prolific serial killer.

---excerpt---- By David Rank June 23 at 8:20 PM https://www.washingtonpost.com/opinions/why-i-resigned-from-the-foreign-service-after-27-years/2017/06/23/6abee224-55ff-11e7-ba90-f5875b7d1876_story.html David Rank served in the U.S. Foreign Service from 1990 to 2017. The opinions expressed here are his own.
This month, I resigned from the State Department's Foreign Service, stepping down as the senior U.S. diplomat in China and ending a 27-year career. I served five presidents — three Republicans and two Democrats — and, like my colleagues throughout the Foreign Service, took pride in the tradition of loyal, nonpartisan service. I also took seriously my oath to defend the Constitution against all enemies, foreign and domestic, and the obligations that came with representing the American people. When the administration decided to withdraw from the Paris agreement on climate change, however, I concluded that, as a parent, patriot and Christian, I could not in good conscience be involved in any way, no matter how small, with the implementation of that decision....

He is a simpler explanation: Climate 101 1. It's warming 2. It's us 3. We're sure 4. It's bad

Thomas, Don't you remember about a year ago I was talking about an engine that would allow for the construction of a 100MPGe biofuel large sedan? I mentioned the agricultural system as well, but I don't think I mentioned the forestry revolution, nor all the rest.I don't know what silly name I was using at the time, but I'm rather easy to track within this site. By the way, my real name is "Doc". Whom do you think I should reveal my stuff to once it's protected? I'm thinking Barton. He hates me and is honest, which sounds like a winning combination... Doc

I have a problem with your M&M analogy. Where it differs from physics is that the two people eating the red M&Ms immediately emit another M&M for each one they eat and that these emitted M&Ms go bouncing around the room. Some of these find their way back onto the conveyor belt and when the situation reaches steady state, the number of red M&Ms entering on the conveyor equals the number leaving on the conveyor belt. Your graphs reflect the fraction of the photons that arrive at a point in the gas column unmolested CO2 molecules. But having arrived at that point and having been absorbed, the photon gets re-emitted in a random direction. When the system reaches equilibrium, the same number of photons will leave the gas column as enter. So no matter how long the tube filled with CO2 was used by Angstrom, and no matter what the gas pressure, the amount of IR energy leaving the tube would equal the amount of IR entering the tube. Now if Angstrom had used an IR camera to determine what fraction of the photons were able to make the trip without being absorbed and were available for creating an image of the IR source, then his analysis would have made more sense.

Given that he thought, in 2014, that some parts of the world were already seeing dangerous impacts...
Like the 2003 European heatwave, or the 2010 Russian heat/fire outbreak, or the Australian drought, or the California drought, or the Middle Eastern drought, or numerous extreme precip events, some of which were relatively harmless and some of which cost billions of dollars and a few more lives, or...? Well, enough, perhaps. My perspective is that the 'dangerous impacts' experienced so far this millennium amount to (un)comfortably more than 100,000 premature deaths and $100 billion. Better informed estimates generally seem to run higher... though there don't seem to be many that really try to do a comprehensive count. Well, attribution is hard, not least in cases like that of Syria, where the causality involved is quite complex. How many of the nearly half million dead and more than 13 million refugees/internally displaced persons should go under the climate change heading, if we were to try and keep track?

Andrew I doubt Dr Mann has ever stated or considered that 405 ppm CO2 is/was a safe limit. What he stated in the article you linked to was
Furthermore, the notion that two degrees C of warming is a “safe” limit is subjective.
However, I'm interested to know Dr Mann's thoughts about what he wrote then, given the level of CO2 is frequently above that level he thought would offer us a chance of staying below 2C. I've heard him many times suggest that there is room for hope, following the Paris agreement but CO2 levels are now destined to go way past 405 ppm. Does he believe that there is any reasonable chance that the temperature anomaly could be limited to 2C? Given that he thought, in 2014, that some parts of the world were already seeing dangerous impacts, what does he think now?

Thomas says: "It’s logical to assume that the moderators are not concerned at all about PBL repeatedly embarrassing himself in public. Otherwise those USSR posts would have ended up in the bore hole where they belonged." Thomas, you are the one who received a full reprimand from the moderators of this blog telling you to 'Knock it Off' with the lengthy, rambling posts and multiple pointless links and clickbait. An intelligent person would have taken the hint and dialed it back but because you don't have the ability to moderate yourself, others have to. Sad

200 Al Bundy - I am confused - what's this about?
