Which way is it? I hear the rockies stopped growing, so is the US turning back east? And how about South America? That too? I know that Australia is approaching the US. Is it drifting north-east faster than North America to the east? And if there becomes a speed difference between North and South America, then will the Central American land bridge break and open up the sea currents again, to end all ice caps and bring earth's temperature back to the normal 25 C average? What do you think?
