Here's a test game with the correct settings and starting location (btw to choose "cold" you need to choose it on a different map script, then switch to tectonic. It seems to have some effect, given the large amount of ice I spotted.)
For the worst possible wonder scenario I took (at least) 3 industrious civs.
First impression: Impossible to get access to the stone in time for early wonders, even with the Adventurer bonus...
2750 Stonehenge
2650 Hindu Shrine(!)
2525 Great Wall
1850 Great Lighthouse
1575 Oracle
1400 Pyramids
Two of the AI I met have 9 cities in 1000BC, the others 5.
Barb Archers at 2225 BC, 3 Galleys plundered my clam around 1500 BC.
Tokugawa got Alphabet at 2000BC, probably from a goody hut.
Good luck everyone
P.S.: to make it ultra-clear, none of the above wonders was built by me
/EDIT: On second try, I managed to whip the Great Wall in 2400 and chop the Pyramids in 1650. I concentrated on founding my 2nd city right on the stone as soon as possible, researching AH afterwards. (Adventurer)
