Are you making me face negative again? Is'nt AC a very worldly expensive commodity? I don't know man...but , I don't want to be around when that day comes.

The earth still goes in cycles. We have winter, spring, summer and fall. We have warming and cooling cycles as well...we are in a warming one right now. We are still leaving the ice age. There is still ice where at times past there was not...we know because the ships cannot travel the routes they did before because they covered in ice.
If you mean cycles in geological spans you need start in powers of tens of thousands of years for Ice Age glacial/interglacial times alone.
Those will continue whatever effect we have on the Earth and its climate within mere human history terms. The last glaciation lasted around 100k years and is considered as finished in our terms around 12ka - although it hasn't really as we still have a lot of terrestrial and sea ice. This was well before recorded human history, let alone ships. There were people around at the time but they would have found it relatively easier than we would to cope with natural climate changes, which are slower than we are seeing now. They could and would simply have migrated to more comfortable regions.
Astronomical cycles such as the Earth's axis precession and the behaviour of the Sun are of course outside our control, as are the planet's Magnetic Polar wanderings and reversals.
Continental Drift is not cyclic but nothing we can do that will affect that and its consequent earthquakes and volcanoes.
