Russell: "This time, the taxpaying audience should demand NASA's full bandwidth and the eye-popping resolution of an IMAX camera. For if we encounter anything not of this Earth on Mars ..." Nicely said. Yeah, as long as it's not going to be looking at Earth as Triana/DSCOVR does, funding for a good imaging system could be possible.

KIA 160: Scientists have been caught fudging data, hiding emails which don’t fit the narrative, etc BPL: You're a god damned liar.

a "science paper" is up there with an episode of InfoWars.
Your sources are unreliable.

I should say, re: my last comments about censorship, that once an hypothesis or idea has been put forward, thoroughly studied, debated and discarded (if deficient) then further discussion using the same information that was previously examined and found incorrect (and barring a revision of the examining science itself) would be a distracting waste of time. In that case, then yes, censorship would be appropriate. For example, flat Eartherism. But to get to that point, free discussion of the idea needs to be allowed in the first place.

More attention needed to slow-growing forcings:
Most of the dust that's settling in places like the San Juan mountains comes from the desert southwest, from land disturbances like farming, oil and gas drilling, cattle grazing, recreation and residential development on the southern end of the Colorado Plateau. "It's kind of a slow crisis, a slow disaster," said Rich Reynolds, an emeritus researcher with the U.S. Geological Survey in Denver. "It's not like a hurricane. It's not like an earthquake or a volcano." In the past 50 years, as the Sun Belt boomed, scientists recorded a dramatic rise in the amount of dust being deposited on snow — which forces fundamental changes in how spring runoff occurs. Reynolds says reversing this trend won't be an easy task. "There's no one size fits all in terms of mitigation for these kinds of source areas," he said. "Plus, these are large, large areas." In a 2010 study researcher, scientists found that in heavy dust years, the Colorado River's flow on average peaked three weeks earlier than in years without heavy dust deposition. The same study also found that earlier melting snow reduces the amount of water that runs to the Colorado River by about 5 percent. That's more water lost than the entire state of Nevada uses from the river in a year. And then there's climate change. University of Utah hydrologist McKenzie Skiles recently co-authored a study that examined whether warmer temperatures or dust are greater threats to snowpacks. "What we found looking at those two in this region, is that it was actually dust that controlled snowmelt timing and magnitude and sort of how fast snow ran out of the mountains, as opposed to temperature," Skiles said. "We didn't see any relationship to temperature at all."...

# 158 Arek, and # 159 Nigelj, Thank you for your thoughtful responses. I think I will wait a bit longer to see if anyone else responds before I follow up.

Comment on Stronger evidence for a weaker Atlantic overturning circulation by Dan DaSilva

76 Hank Roberts (quote), 74 jgnfld (in general) "Science is so powerful that it drags us kicking and screaming towards the truth despite our best efforts to avoid it." On longer time frame, I would agree. All bad science tends to be found out. (To use a climate/weather analogy the climate debate we have now is the weather.) Sometime in the future, more and more truth will come out. Just do not expect science to never go down a rat hole. It will go down rat holes (and has) but it will return. Why does it take so long in this case? The facts cannot be easily tested, this is a very complex chaotic system and the ratio noise/signal is high. Also, the science is also polluted on both sides by politics. 70, 71 Carrie: Well said, we are all only human and the best we can do is be self-aware. Climate Models: As far as models I was pointing out why they should be treated with skepticism, not that the climate scientists are abusing them as badly as my example. If you want an area of actual abuse, look at aerosols and their role in climate sensitivity.

Thanks Gavin and Adam. As a geologist this is something I've pondered as well. Think, as an example, about how rare and limited footprints in mud are, and the lucky geologic breaks that allow them to be preserved and lithified. Now think about the pervasive impacts we as a species have on the environment. Also think about the limited geologic time horizon we have occupied and likely will ever occupy. I've always envisioned this as a future geologist, or whatever they might be called in the future, stumbling on an outcrop in a sequence of sedimentary rocks and thinking...well this is a bit strange...

> KIA ... Want people to believe in CC? Show us the math, show us how the models work. It's no secret.

Interesting. I have speculated about this for some time. I write SF as a hobby and occasionally self-publish. One short story I wrote (not yet in the wild) was about dinosaurs who have a reasonably high-tech civilization but all very sustainable and discover this impact event is due and will put them into an extinction-threatening climate shift. Also working on a novel of a distant future where intelligent insect life has evolved and evidence that humans may have been intelligent shakes things up. Until we encounter a different form of intelligent life, we just don’t know if intelligence can evolve from a different start – notwithstanding that some life forms are in various ways pretty intelligent.
