Depends on what you're asking, as in humanity or all life will be destroyed, or the entire globe. For the entire globe is probably when the Sun cools down enough and expands bring in us in.

the entire globe

They've found something ma'am, something beneath the storm.
The worl dwill end in about 3-5 billion years, when the Sun turns into a red giant, then a black hole, then dies. Then, the Earth would die. That's what probably will happen, read it off Wikipedia
Earth will end when the sun dies out in about 5 billion years or so. By that time, the human race would have either made space ships and left the planet a long time ago, or have gone extinct from a disease/wars/running out of resources/gaint meteor.

You serious? The sun would just get less dense, and it's mass and gravitational tug would remain the same. Also, in 5 billion years Sol will expand into a red giant, consuming Mercury, Venus, and possibly Earth.
The world will truly end in 5 billion years, when the Sun uses up its supply of hydrogen and expand into a red giant. It will engulf Mercury, Venus, and most likely Earth.
However, due to the Sun gradually getting hotter (not related to anthropogenic global warming), in 1 billion years, the oceans will dry up and life would go extinct.
Hopefully humans have progressed technologically enough so that they can prevent these scenarios from causing too much devastation.
Actually, to the people talking about the Sun becoming a red giant, life on Earth will already have been wiped out - long before the red giant in five billion years. The Sun gets 10% hotter every billion years due to the internal fusion reactor having to work harder due to less fuel being available in the Sun's core. This means in ONE billion years, the Sun will have gotten hot enough to boil oceans and make the Earth an enormous desert. Of course, the Earth itself will live just fine, just many degrees hotter. Don't quote me on this, but if the temperature of the Earth right now is about 55 degrees F, then in a billion years, the temperature will have risen to over 150 degrees, average. The Equator will be blazing and the poles won't be much better. Water, and thus life, will not exist at that point, on Earth. Four billion years later, the Sun will engulf and destroy the entire Earth, nothing is left behind.
The "world ending" has two definitions, as many of you have stated. Life end here at about 1,000,000,000 years, the Earth itself will be destroyed in 5,000,000,000 years. Long time....
Some people really need to stay away from the government propaganda department. Let the brain-washing machines have a day off, they must need maintenance by now.

Figured I pull in some actual info. Basically the sun will expand, before it collapses.
"Earth's fate is precarious. As a red giant, the Sun will have a maximum radius beyond the Earth's current orbit, 250 times the present radius of the Sun. However, by the time, the Sun will have lost roughly 30% of its present mass due to a stellar wind, so the orbits of the planets will move outward. If it were only for this, Earth would probably be spared, but new research suggests that Earth will be swallowed by the Sun owing to tidal interactions." -source wiki answers http://wiki.answers.com/Q/How_will_the_sun_die
in my opinion i chose NEVER!!!!

Humans will likely be extinct well before that though.
Otherwise, never.

But if you mean the literal globe, then I have no idea.
