What will happen if World War III occures?

Very doubtfully, I don't think anyone is going to nuke every corner of the planet. No ones going to waste any on the hundreds of thousands of tiny islands throughout the world - or trying to level the amazon rainforest. Or take out every tiny town in northern canada, the australian outback. etc. etc.

Also consider we already have dropped thousands of nukes on the planet... 2000+ - albeit not all on cities that would create more pollution, but it would be survivable.

Likely billions would survive honestly.

A new peace treaty will be established which is worth nothing in present or future!

Perhaps billions would survive the initial war; but with cities destroyed and governments and industries in dust, how would life go on for those of us who live in those small towns and villages of the fringe? Automobiles and farm tractors would break down. Who would be left to repair them and keep them running? With what spare parts? With no supply chain to provide the few remaining stores of parts still in existence? And how would anyone get fuel anyways? Or make telephones and computers work without the infrastructure? Or get food and clothing to people's tables and homes? How would clean water be provided? How would hospitals continue to care for the ill and injured? Then let's not forget that the following nuclear winter would probably produce world wide famine. Khrushchev had this one right: the living would envy the dead.

Well - I can't think of any legitimate targets in the entire southern hemisphere

countries like NZ, Australia, Indonesia, southern africa, south america, etc would likely be nearly completely untouched - and there is probably nearly infrastructure enough amongst those that survive to make almost all things work. There are a lot of work arounds, and yeah it would be an adjustment - but humans are extremely adaptable under trying circumstances.

and the world has dealt with volcanic winter - I'm sure it can handle a nuclear winter - it might be tough - but I'm sure people would make do.

One asteroid likely took out all of the dinosaurs. If we had a full-blown nuclear exchange, I doubt that any humans would survive. Maybe the cockroaches would survive, I don't know.

the power of all of the nukes in the world being set off simultaneously is almost completely negligible compared to the asteroid that struck earth.

"The asteroid that killed the dinosaurs, which struck Earth around 66 million years ago, released an energy equivalent to roughly 10 billion times the power of a Hiroshima atomic bomb, meaning the impact was significantly more powerful than a single nuclear weapon; some estimates put it as high as 100 teratons of TNT"

Even with more powerful modern ones there's no comparison

to emphasize again the difference,

"Current estimates of all nuclear weapons on the planet right now is around 4000 megatons"

The asteroid was 100,000,000 megatons.

It was so huge that it knocked up large chunks of earth into the atmosphere which rained across the whole globe almost setting the entire planet on fire.

You might be right about the energy content, but I think you've ignored the radioactivity factor.
