Since when were the days stable? It was always variable in terms of milli/microseconds from day to day. Its not exactly 24 x 60 x 60 every day. | ||

things you should be aware of here are the following: a handful of degrees increase in average global temperature can make huge changes to climate. climate (local temperature) is related to how long different localities are exposed to sunlight (and also the angle at which it hits the earth). if one earthquake already shitfs the axis by 8cm just think about how many factors of similar or greater magnitude can and do occur and will shift this axis as well, and what this will say about the length of day/night and temperature shifts that come with it. a lot of people say that 1.26 microseconds is no big deal and speak of the proverbial sack of rice in china, but polar icecaps are melting (they are a pretty considerable mass), tectonic plates are moving all the time, earthquakes cannot be averted, supervolcanos exist and asteroids/comets do as well. there are a lot of things that could cause severe problems by shifting the earth rotational axis seeing how easily it can be shifted. and id really like to see the people shouting "who cares" now when their ecosystem collapses. maybe they dont care because a human only lives to 70 (if he makes it that far that is). but that doesnt make the effects of such things any less grave or harmful. | ||

Oh well. As long as all of earth's history is erased before I've done anything great, I won't have much to regret. I'll only be pissed if it's after. | ||

Pretty decent documentary. | ||

Even though I giggled at the movie 2012 and its theories, the amount of natural disasters that have occurred lately, and the ability of natural disasters to have such an impact on our planet as to possibly have shifted the Earth's very axis just shocks me. Thoughts? Reactions? I doubt it's that natural disasters are occurring more frequently, it's just that with internet and all you actually hear about shit. A hundred years ago you wouldn't even be aware it happened. | ||

It does seem like a lot of big disasters are happening close in time to each other for the last several years. I don't remember there being this many in the 1990s. | ||

Microseconds. 1.26 µs = 1.26 * 10^(-6) s, so rather than lose a second every 8 days, we lose a second about every 2200 years. Since there are already leap seconds that indicate our solar day is increasing in average length much faster than earthquakes (such this one and the Indonesian tsunami) are shortening it, I don't think we have to worry about noticing changes in the lengths of our days. As has been said, the bigger problem is the axis-shift. | ||
