Is it possible to synchronize climate change in the two Hemispheres?

Question

Can it be done?

How's it done?

Answer 1

No.

The Northern Hemisphere has most of the land (which can warm pretty rapidly), the Southern most of the water, which warms more slowly.

Answer 2

No

Answer 3

If you don't want your climate to change, stay within 3 feet of the equator for the rest of your life.  Watch out for snakes.

Answer 4

ocean currents.

Answer 5

I disagree with Bob on this one.  The oceans are a huge heat sink, cover most of the planet, and they're constantly moving and redistributing heat.

"climate change is synchronised between Southern and Northern Hemispheres, with a growth of ice sheets during glaciations occurring in the Arctic and Antarctic. It is now widely believed that the circulation of the oceans provides the forcing factor for synchronisation (Duplessy & Shackleton, 1985; Broecker, 1987; Broecker & Denton, 1990; Boyle & Keigwin, 1987). This is discussed further in section 2.6.4."

Unless you provide more information and a link, few people are going to know what '03 paper you're refering to.

Answer 6

no unless you could somehow build a massive heat pump on a global scale. the energy requirements would probably accelerate global warming further.

Answer 7

I didn't have a clue what you were talking about, until I read the rest of the post.Then I read (shapeshifter's)answer then...wham!... it made sense.

That concept would be the Holey grail to proponents,basically ending a major dispute with the GW theory.The impasse however, as it stands unproven, can still justify incremental changes in temps.So it's a win/win concept for alarmist.I know the study is ongoing but haven't found any new links to it.All I can offer is a old link that is slightly ambiguous....but a good question if you dwell on it.
