If you don't appreciate The Motion Picture as a movie screen sized hours long version of a TV episode and opportunity for the first real beauty shots of the Enterprise, then you are no real Trekkie. :P
Maybe it's because I went to see it when it came out as a kid and it following the success of Star Wars simply blew me away. Best opening and intro of a retcon ever (the Klingons of course). Of course I like Wrath of Khan more, but I will defend the first movie every time as a masterpiece too.
Might relook at the chart and scale, none of the recent interglacial periods hit 4C, only one topped 2C. Plus note that the x axis is logarithmic, so the time that things happened increase as you look back. The PETM took hundreds of thousands of years to start dropping down, but also a thousand years to ramp up. Compare that to our "instant" climbing now started only a hundred or so years ago.
If you mean all the rest I wrote, time will tell. That we've lost so much in biodiversity already and haven't had things play out completely doesn't suggest that things will be "fine".
Extinction event level but not really, since some human groups didn't show a remarkable effect. A large percentage drop in total population doesn't mean much when it's concentrated in certain areas and the total number of humans is very low already because hunting/gathering isn't conducive to large species numbers. Did you note the one mention of the theory that adaptation of affected humans' behavior might have been the driver for aggressively taking over Neanderthals through killing and incorporating captives into the groups?
Circling back to the point at hand of the thread, climate change is far greater a threat on all species than past recent geologic events, even possibly surpassing ones such as the PETM which is the closest in comparison and definitely an extinction event. Humans haven't experienced that level, ever. They weren't around.
I never said Toba didn't happen. We're just debating the degree it affected the entire species, and if you want to bring better evidence to support Toba being a bottleneck, go right ahead and add the citation.
I used to quote the initial Toba theory myself years ago, but more data leads to a more localized event. That's okay, that's how science works.
You should read the entire article. Toba hasn't held up well to additional evidence. It was certainly hell for many in the area, but it doesn't seem to be the bottleneck that people still quote it for.
Life in general does rebound, it's very persistent. That doesn't mean most life won't die off, nor will the rebound be quick and even resemble what we had. My own opinion is that we may have been witness to the peak of biodiversity, something that won't even happen at that scale again simply because it needed specific conditions to be so vast.
This has been circulating for years, and the accuracy of its predictions are high at the equator and drops off quickly as you go towards the poles. This map falsely implies that we'll just move out of danger and be fine. Canada, Siberia, and Western Antarctica are imagined almost as futuristic paradises.
Even better if you happen to watch it without knowing the plot and twist. The incredible thing is how it only needed mainly a single room for most of it, as it's all about dialogue and imagination filling in the rest. It originated as a play.
There was an attempt at a sequel, but like some movies I think it's best to end it with the first and let the viewer imagine how the future continues.
If it was a single action on a single company then I might agree. Elon's done some stuff, Twitter being only the latest, that shows a trend of...well maybe not stupidity, but it does seem to be flailing around of a rich person without a clue. He seems more of a wealthy tool than one of the higher ups making the plan.
It's a good primer for anyone who hasn't heard of Sonny White's work or the Alcubierre theory/drive. Currently the best option we have at the moment for making any progress beyond conventional action-reaction rocketry. Also very far away still. The biggest error is in the subtitle, claiming "reach the far ends of the cosmos in the blink of an eye". If it worked it would be magnitudes faster than anything Newton-related we can imagine, but it's still enormously slow compared to the size of even just our galaxy.
A great beautiful video short by the amazing Erik Wernquist (and narrated by the same Sonny White) called "Go Incredibly Fast" shows how big even "near" space is.
Another good example is in the game "Elite Dangerous" which uses the Alcubierre concept for its local space drives making travel within most systems reasonably fast. Even in the game use going from star to star they resort to a more instant "wormhole" technique as the warping effect would take too long to get anywhere in the galaxy.
But without some kind of loophole past Newton and Einstein, we're pretty much stuck in our own solar system, or to end up using generation ships that take hundreds or thousand of years to get anywhere.
Two issues with running the blower all the time. One, wear and tear on the blower over time. More importantly though, the coils in the unit need occasional downtime to let moisture drain for best efficiency. Your points on moving air while not cooling are valid though, and newer thermostats do have a circulation mode that will cut on the blower for a percentage of the time the AC itself isn't on to do move air around. Good for second story homes with one AC, as the thermostat is usually on the first floor while the heat rises to the top floor.
Many good suggestions, but I didn't see anyone bring up how well the house is holding the temperature, aka insulation or leaks. The best AC can't keep it cool if that cool is going outside somehow. You say the vent air feels cold so it seems to be doing its best. Single pane windows, especially facing the direct afternoon sun will be hard to keep from undoing the cooling. Attic space that has little insulation will also defeat the efforts.
