Anything to say about it? Or just a link? Oooh.. 407 measly pounds? Please Register or Log in to view the hidden image! I don't see any mention of the rate of influx of material. Some conserative estimates have that at 100 tons per day. http://curious.astro.cornell.edu/ab...y-meteorites-hit-earth-each-year-intermediate
Yeah, 400 + 7 pounds, that's per minute! And we are not talking about solid stuff. Perhaps you missed the fact that it is earth's atmosphere that is leaking these gases. So, don't worry........Please Register or Log in to view the hidden image!..........but then, there is also GW (increase in escape volume),.........Please Register or Log in to view the hidden image!
Yep That is 400 x 60 x 24 = 576000 (pounds per day). and 7 x 60 x 24 = 10080 (pounds per day) Moreover, if there is a steady increase of depletion at say, 0.1 % per year, by the exponential function, these numbers would double every 700 years. While it is true, the atmosphere is very large, it also relatively very thin and any reduction in density may result in some cery unpredictable results. One example is the ozone layer which was being depleted by our release of chlorofluorocarbons . And this only took a few decades. And after we stopped releasing this stuff into the atmosphere, it took some 40 years to begin to repair itself.
