Zogo posted:I've seen many documentaries, TV shows, articles mention the dangers of the average atmospheric carbon dioxide increasing yearly in PPM but I've never heard it mentioned just how high it can get (exact PPM readings) before people go outside and start choking to death or at least get severe asphyxia. I believe there are some that won't feel any urgency or worry about it until it gets around that point. Currently C02 is about 400 parts per million in the atmosphere. Deadly levels are about 90,000 PPM; levels causing "some to become drowsy" are about 10,000 PPM. So, basically, C02 would be well beyond even a climatologist's worst nightmare before we'd feel the effects physiologically from breathing it. We'd literally bake before we'd choke.

Thanks, I guess we're not really close to that number. I wonder if there's some kind of threshold where CO2 would get so high to cause some kind of cascading effect where the planet would be irrevocably damaged. Maybe we don't know that exact number. If it came down to a heat issue I can see people walking around outside in space suits to withstand the heat.

We don't know the exact number but we do know that we're very close to it, maybe even past it. We're getting to the point where unless we find a cheap effective method of pulling CO2 out of the atmosphere and storing it, we may be past the point of no return. Like NDGT said in the last episode, the melting ice is releasing huge amounts of stored CO2 and methane, which is creating a very dangerous feedback loop that we probably will not be able to stop if we don't do something very serious within the decade.

Just saw the last episode. Much as I love NDT and respect his right to tie a bow on his own series, it should have ended with Sagan's pale blue dot speech. That is such a profound and moving bit of prose that I would have liked to just be left there with that image and some silence for a couple of minutes. Also, a lot of people probably know this, but it's awesome so I'll repeat it anyway. On the Voyager Record, there's a bit that Neil deGrasse Tyson described on Cosmos as "the EEG of a young woman in love". That young woman was Ann Druyan, and the person she had fallen in love with was Carl Sagan. They had fallen in love over the course of preparing the Voyager record, and it had just come out over a phone call two days before she got her EEG. It's beautiful to think that some day, some alien civilization might find Voyager, and the most intimate insight they will have into the human mind is Ann's first rush of love for Carl. That's got to be one of the most poetic things humanity has ever done, and Voyager is likely the best love letter that ever has, or will be, written. More about it here: http://science.nasa.gov/science-news/science-at-nasa/2011/28apr_voyager2/

Why replay something that we already have, when we could have a (most likely not as amazing but still) poignant closer to the second version.

JossiRossi posted:A good analogy might be how Reading Rainbow isn't about teaching kids to read, it's about getting kids excited about reading. This how I see Cosmos as well. It doesn't cover the details that deeply, but it does get people excited about science. Overall I was really happy with the quality of Cosmos(2014). Carl Sagan's enthusiasm was probably my favorite part of the original series, and NDT really did a great job as well.

AFewBricksShy posted:While I love the pale blue dot speech, this is NDT's version of the series. We already have the pale blue dot from the original. I haven't seen the newest episode but with Sagan's focus on "let's not blow each other up", vs NDT's "let's not kill the planet", I'd like to hope that Tyson gets his chance to make a similar well thought out closing statement that would better encapsulate his argument than the pale blue dot would. The pale blue dot speech strongly stresses that we are all one, and that we should treat each other as brother and sister because we are all a part of the same small note of dust suspended in a sunbeam. I hope Tyson's is similar, but showing that not only are we one as one species, but that we are tied to our planet and are one with it as well. That's why I said I respect NDT's right to close out his own series. I realize you said you haven't seen it yet, but NDT DID replay the pale blue dot speech, and then does about five or ten minutes of his own closing thoughts after that. The problem is that NDT's ending seemed pretty frickin' weak in comparison. Like, from a creative perspective, it seems like you'd want to end on your strongest note. NDT's ending was all right, but just didn't have anywhere near the impact of Sagan's speech. That is like getting The Beatles to open for your band or something; even if you're really, really good, you're just inviting a comparison against a standard that is drat near impossible to live up to. If the goal was to end on a strong note, NDT should have either put the pale blue dot speech at the end or left it out entirely. As it is, it feels like the episode really peaks about five minutes before it ends, and then just sort of meanders off to a weaker ending after that. Maybe you'll disagree, but you should probably see it first before you decide that I'm wrong.

I just saw the last episode before any of you guys too, and I thought the placement of the pale blue dot speech was very strategic and helped the pacing of the episode. The rest of the episode felt like an epilogue. Overall, I'd say it's a perfect capper to the series, and will probably go down in history as one of the best finales of all time. Please don't let this color your opinion of the show, but I think you should know that it's great, but you should really see it before you form an opinion, but it's great it's the best.

Yeah don't get me wrong; on balance the whole thing was very good. I'm just talking about an aesthetic choice in the last episode that I didn't think was very well thought-out.

That was a good episode, sad that it has to be the last. But hey, guess what, a science based/historical show aired on major TV networks around the world in 2014 in prime-time slots on over 120 channels each week in a dozen languages.
