So people who religiously apply sunscreen, or live exclusively indoors, can be expected to live 900 years?
and create a greenhouse atmosphere, where plants and animals and people would grow quite large.
I'm not sure what this means. So in the tropics, it's hot and very human, people would be expected to grow very large. Like the pygmies, say?
In addition C-14 decay would be drastically different than it is today.
Nothing we currently know of nuclear physics allows a significant change in the 14C decay rate (unless the 14C is in another frame, and the rate will be the same measured within that frame. )
very humid, dammit.
ROFL! I haven't heard that argument for a while.
Nope. It doesn't work even a fraction as well. The protective canopy as well as the nutritive qualities it gave to the plants we would have eaten then, are gone.
Said canopy would have also increased atmospheric pressure. I hear that hyperbaric chambers can speed bodily healing.
Are you suggesting we try and set up a protective canopy over the earth so we can study the effects? Where shall we accurately duplicate such conditions?
In a greenhouse, partially. But you'd be leaving out a lot of factors that we cannot duplicate. Yeah plants tend to grow quite well in those greenhouses...
Things also have adapted to cope with conditions we have now, so it may take a while to get results. Yes, creationists *do* believe in adaptation and some amount of 'microevolution.'
I'm thinking that it had to do with the amount of carbon that would be present in the atmosphere when under a canopy of ice.
