Climate is a long-term average over a large region. Weather is the specific conditions at one specific place at a given time.
You can predict the average value of, say, rolling two 6-sided dice a million times (average is 7), but that still won't tell you what you get on your next roll in a craps game. Averages are easier to predict than individual values.
I'm not sure what "established climate scientist" you're referring to, but we already know about water vapor. We've known about the greenhouse effect of water vapor for over a century. It's not an "alternative model": water vapor is incorporated into every climate model since Manabe and Wetherald 1967. We wouldn't understand the temperature of Earth at all without understanding the greenhouse effect of water vapor.
Water vapor, however, goes into and comes out of the atmosphere on a time scale of days, due to evaporation and precipitation. Unlike CO2, it does not accumulate.
Let's start again.
What I said was high-voltage transmission lines are not "spanning continents" and they were not cheap. All the posts since then have emphasized that point.
Get it now?
I don't believe their bid was accepted at first. They had to fight to get it considered *in addition* to ULA, I think they're called.
Their bid won in the first round. It is unlikely that ULA would have put in a bid for the lunar lander (they are solely a launch vehicle company-- the individual companies, Boeing and Lockheed, the components of ULA, were part of the Blue Origin "National Team" bid). https://www.cnn.com/2021/04/16...
Blue Origin sued NASA to be reconsidered, saying that they didn't know that cost was so important, but lost their case.
I'm trying to understand the narrative here. I understood from many, many Slashdot posts that Elon Musk and Donald Trump were partners in crime and
Huh? Elon Musk funded Donald Trump's presidential campaign, indeed, but I don't see how that makes them "partners in crime." The Supreme Court ruled that billionaires are allowed to fund political action committees. If you think that's a crime, blame the Supreme Court.
that SpaceX was Elon's tool for milking the US govt for no-bid contracts.
SpaceX doesn't get any no-bid contracts; they are just very successful in winning bids. But they win because their bids are typically lower in cost than the competition. The solicitation to provide a lunar lander to NASA was open to anybody with the capability to make a credible bid, the contract was bid won by SpaceX because their bid was significantly lower in cost than any other bid.
This kind of video is why I tell people to get your science from actual scientists, not from youtube.
No citations, of course, which is par for the course for youtubes, but the one reference he actually gives is "the IPCC reports". You might try reading them: https://www.ipcc.ch/synthesis-...
Has Blue Origin even achieved orbit yet?
Yes, they successfully made orbit with New Glenn: https://spaceflightnow.com/202...
Haven't done a second launch yet, but do note that they are providing engines for Vulcan.
With respect to a lunar lander, that's more like a rocket-powered soft landing on Earth, which they now do routinely with New Shepard.
Contract it out to one of the Russian or better yet even a Chinese launch provider,
I don't think that the Russian space program has had a successful mission past Earth orbit since 1986. They're not really in the race anymore,
You aren't thinking. My point was that we are not wheeling power over transcontinental distances (and that it is not cheap to do so.) Saying "but that project hasn't even been completed yet!" supports my point.
Your post says that we (or at least China) are wheeling power over transcontinental distances. Saying "but that project hasn't even been completed yet!" repudiates your point.
In short: you are vigorously agreeing with me. Thanks.
And China just completed their ultra-high voltage DC project spanning almost 1500 miles
Strike "just completed". Substitute "is scheduled to complete next year".
You should read the links you post before posting them. From that article:
...Upon its operation in 2026, the project will deliver
...
Also, the comment being discussed said "They were not "spanning continents". And they were not cheap" 1500 miles won't span America, much less come close to spanning Asia, and the article does not mention cost.
Slashdot is hosted on two squirrels and a dead badger running Linux.
Wow, +1 for the obscure Lucy Snyder reference!!
"High-voltage transmission lines over thousands of miles are not cheap"
someone has been saying that for over 100 years yet somehow distributed grids spanning continents got built
They were built. They were not "spanning continents". And they were not cheap.
To my knowledge, the longest high-voltage power transmission line in the US is 800 miles long, transmits 5 GW, and cost 1.7 billion dollars.
