we will be " off planet" within a thousand years searching for new homes anyway, colonising the milkway, we have spotted numerous " earth like planets"
already, its only a metter of time and technology before we move
Won't be hard. There's an already built city or two we could just move into on mars mate.
The Moon is the ideal candidate in my opinion, utilising their forests, oceans, gold and such.

To be fair when the sun goes supernova we will want to be a bit further away then the moon!!

Evolution doesn't just stop. Humans as they are now will evolve into something more suited to their natural environment, whatever that may be. If we classify all species after us that are our descendants as "humans", then we'll quite probably survive for the rest of time. We might spread ourselves out around the galaxy and have several divergent species, but as I said, these are ancestors that for the sake of this example we are calling "humans".

It is almost impossible to wipe out human life. We are far too well spread and biologically advanced to do so.

A nuclear war might wipe out a few hundred million. An asteroid might kill a few billion. But there's always some people left so the species continues. Even an out of control virus will have certain humans who are genetically resistant to it, just by the law of averages. Those will continue to survive and will pass the immunity on to their children.

People talk about the food chain, but humans will adapt to survive. It might mean that we will start eating more and more insects as our primary protein. It might mean that we start cannibalising each other. It matters not, we will survive in numbers somewhere.

Even if the worst possible climate change event happens, we will still survive somewhere. There's literally no realistic scenario that could cause a species wide extinction across the entire planet outside of the planet itself exploding and that would need another planet size object to hit it. Maybe we could poison the atmosphere but as it would be a slow event, when it started killing the elderly and the like the human species would adapt, either by changing behaviour or by invention.

I'm all for ideas here, as I can't think of a single thing that could possibly kill us all.

Our descendants will adapt to their new surroundings and rediscover the science that brought to where we are now. The future of "humanity" is definitely in space, whether that be us as a species or somebody quite like us, it is where we will end up when all said and done

A shift in the Earths magnetic field could be an extinction event, Scientists reckon that it could do a full tilt so the magnetic north becomes magnetic south. During this tilt which could take months even years the Earths ability to fend off solar radiation would be zero as the field could disappear completely.The radiation would be catastrophic for all life forms land based and in the oceans..Would it kill everyone?? who knows but it would be pretty grim, the power grids would be gone and we would be thrust into the dark ages. No power,communication,transport,fuel,food growth and definately no governmental rule..

Scary.

Read this.. very interesting.<a class="postlink" href="http://io9.com/395272/is-earths-magnetic-field-failing-us" onclick="window.open(this.href);return false;">http://io9.com/395272/is-earths-magneti ... failing-us</a>

We can already live outside of the earths atmosphere for prolonged periods so survival on earth is more than possible. We have had NBC shelters since the days of the cold war and nuclear subs that can spend extended periods submerged. A couple of months notice would be more than enough.

The magnatic reversal is a process that takes a long time. We are in it now, and at no point would the magnetic field turn off.
 
I think you're all looking at this the wrong way...

What about God...

Scientific Nonsense.

When the sun expands, it will swallow the solar system so we have to find another star and a planet capable of supporting life in that solar system

The nearest star is alpha centauri which is 2.4 light years away.

Do the arithmetic and overcome the laws of physics.

Evolution won't save the planet.<br /><br />-- Fri Sep 07, 2012 2:09 am --<br /><br />

Which bit is scientific nonsense?
 
Four billion years is a very long time. Inevitable that we'll be twatted by a huge asteroid well before that. The poles flipping is an interesting one - seems that it happens pretty frequently relatively speaking.
