This looks like a very interesting paper, suggesting that a Tunguska-like event wiped out the ancient Middle East, and could explain a lot of myths. (Ctrl-F for “Tunguska” to see the specific abstract.)
And of course, it has current implications that we’ve been lucky, and dodging bullets.
I continue to be amazed at people who continue to attempt to compare landing a probe on another planet to predicting something as complex as the climate and the economy eight decades from now.
The Administration now has a problem since some Democrats say they will use the report to oppose a number of the Trump Administration’s attempts to weaken a number of the Obama climate regulations that they have proposed, including using the report to persuade courts to reinstate the original Obama Administration regulations. All this was quite foreseeable. So why did the Administration publish the report without reviewing it? Was it because it was not paying attention to what the bureaucracy was doing? This is hard to believe, but appears now to be the case. One obvious possibility is that they wanted to avoid the charge that they had “corrupted” the report writing process. But the costs are likely to be high. Another possibility is that Acting Administrator Wheeler did not want to endure questions about possible intervention at his confirmation hearing. But the evidence appears to suggest inattention by the Trump Administration was the major problem.
This is from last summer, but I finally got around to reading it. I’m wondering what the implications are for space colonies, potential botanical gardens and zoos in the solar system, and the O’Neillian/Bezos vision of earth as a nature park.

In reading this:
Because one cannot conceive of the length of geologic time, one cannot comprehend the brevity of the past 75 years in relation to it. The Anthropocene, if officially recognized, would be inconceivably ephemeral, momentary — indeed, instantaneous — existing only in real time. But it will endure until the Götterdämmerung, that is, until humans go extinct; it will run to the end of recorded history — turning the hourglass of geologic time upside down.
…I’m reminded of people who believe that every hurricane or fire is some unprecedented event, caused by our SUVs, when most are unaware of what happened a century ago, let alone millennia.
This article is sort of amazing in its complete lack of discussion of the keto revolution, and its old timey referrals to “diet” and “exercise” and calories.
Janet is an excellent choice. It’s just a shame that Bridenstine couldn’t get the deputy administrator he wanted.
I’m honored to welcome Janet Karika as my Chief of Staff. Her 38 years of space experience will serve the agency well. I’d like to thank Tom Cremins for doing an outstanding job as my Acting Chief of Staff. It’s an exciting time at NASA, and I’m very thankful for our team. pic.twitter.com/79pflMbYcy
Why have I devoted so much time to the sea level rise issue? First, I regard sea level rise to be the most consequential potential impact of predicted global warming. Second, there is a great deal of public confusion about the issue, including decision makers. Third, a number of CFAN’s clients have queried me about a range of specific concerns that they have regarding sea level rise (and I have been doing consulting on this topic).
Why do I think an independent assessment of the sea level rise issue by yours truly is needed, given the plethora of international and national assessment reports? My clients are concerned about the alarmist predictions they have encountered. I have seen various ‘experts’ make public statements projecting 21st century sea level to be as high as 9 m [30 feet]. My clients are looking for someone that they trust to provide an objective assessment that focuses on their issues of concern.
I am not a published expert on sea level rise, although I have published some relevant papers in oceanography and the climate dynamics of the polar regions. What I bring to this assessment is a broader perspective on the issues of climate dynamics, climate modeling and uncertainty than most of the community working on the sea level rise issue. In any event, it is arguably useful for a knowledgeable person outside of the publishing sea level community to provide an independent assessment.
Yes. It will be interesting to see the response from the alarmists, if any.
This is one of the many reasons I hate going out to eat. In fact, last time we went out, it was on a patio on a pier, listening to the waves, which was quite pleasant.
I think the larger question is why we are seeing such a sudden rash of anti-keto stories. So many of them quote no experts [sic] sources and do not provide citations for their claims. Skeptics with little acquaintance with the diet are quoted exclusively instead. From a journalistic perspective, this lack of balance of viewpoints and the failure to back up claims with evidence falls below basic reporting standards. Offenders on this list include even the Harvard School of Public Health, which recently published more than one unsourced, one-sided article on the keto diet (This is in addition to the Lancet Public Health article cited above, by Harvard researchers, which suggests that a low-carb diet kills you). These stories could reflect lazy reporting or they could very well be scare tactics to steer people away from the keto diet. Why would reporters or scientists at Harvard be doing such a thing? That’s material for another post. Stay tuned.
