"Tidalgate" is spilling over into the debate on sea level rise in North Carolina....looking forward to hearing from realclimate.org on this matter...albeit AFTER AGU :)

How do you guys live with yourself selling BS. Do all you guys work for the government and need more taxes. Any archaeological well read Knows sea level was higher in ancient times. The little ice age (sun went to sleep) froze the world dropping sea level from 1350 to 1856. We are just now warming up a little again. How come you wise one do not know this. There are no Indian remains in most of the FL Keys BECAUSE most of it was under water 2000 years ago.

nigel 98, I think you should pay attention to what a lurker said at #77, and what I have said previously, about quantity v quality. But I will answer this because perhaps you will see how ridiculous your high output has become:
“1. Sufficient numbers to maintain genetic diversity. 2. Sufficient numbers to maintain specialization (that is, a technological culture where everyone isn’t a small farmer)…” Good points, but what do you think might be sufficient numbers, or way of determining this, and how would we know when we get there? We would need to know obviously.
Do you even stop to think? 1. Duh. Ask a geneticist. 2. Duh. Ask someone who knows about the history of science and technology. Or, stop and think for yourself: What's the population of, say, Western Europe? If a plague wiped out every other human on the planet and left them healthy, would they revert to Killian's peasant culture? Why? Seriously nigel, you have too many words and not much useful content at this point.

BPL 96, "nitrogen fertilizer" As population declines, artificial inputs become less economically sound. Before we had pretentious quasi-mystical terms like "regenerative" and "permaculture" and the others, people practiced "crop rotation" and "lying fallow". What's the secret to that? Well, it's all about supply and demand. If you have a growing population with lots of people demanding food, and ten acres of farmland, it makes sense to use fertilizer, let the land deplete, and sell it off for tract housing when you get tired of the work. If you have a stable or declining population, you can buy 50 acres for the same price, and get the same yield without much increase in labor if any. IIRC, the Dust Bowl was exacerbated because of a perceived growth in demand-- so trees were removed, every possible acre was plowed, and drought and wind did the rest. And if we want to talk about "economic growth", let's establish a framework that everyone agrees on. Most basic level: Per Capita? Local, Global? "It's the topology, stupid." (And I guess the topography too given my farming example.)

# 11 Pete Best: "30,000 tonnes of co2 emitted to host this conference" How is that calculated, Pete?

Australian scientists getting into fine-tuning over Catastrophic fire conditions for Bush Fire Ratings "The fires we see nowadays, when we start getting those catastrophic type fires, it was never designed to predict fires of that sort of magnitude," he said. Following the Black Saturday fires of 2009, a new category ("catastrophic" or "code red" in Victoria) was added to the roadside signs to describe conditions more extreme than those thought likely by McArthur. The new system will go a step further by improving the formulas that form the basis of the rating system. http://www.abc.net.au/news/2017-12-13/bushfire-danger-rating-system/9203446 and http://www.abc.net.au/news/2017-09-04/cyclone-and-extreme-weather-events-intensifying-bom-says/8869042

Findings were discussed at the American Geophysical Union meeting in New Orleans. “What happens in the Arctic doesn’t stay in the Arctic; it affects the rest of the planet,” said acting NOAA chief Timothy Gallaudet. “The Arctic has huge influence on the world at large.” About 79% of the Arctic sea ice is thin and only a year old. In 1985, 45% of the sea ice in the Arctic was thick, older ice, said NOAA Arctic scientist Emily Osborne. https://www.theguardian.com/environment/2017/dec/12/arctic-permafrost-sea-ice-thaw-climate-change-report iow more than three quarters of the critically important historically 'normal level' of thick, older ice is gone already! imho keeping an eye on the 'canaries in the coal mine' can help to keep up-to-date with the real status quo. More than 10% of the GBR is now dead. It'll be the reverse around 2050 with only 10% still alive and 90% dead and gone. That is "if" nothing changes fast. fwiw "the canaries" are local droughts, bush fires, record breaking storms and rainfall, the arctic, permafrost, forests, river systems, antarctic, glaciers, record floods, coral reefs, ocean acidification, fish kills, tree die back, extinctions, regional heat waves and record temps ..... it's such a big world, sometimes the left hand doesn't know what happening to the right hand.
