At least, that’s what Stephen Hawking says...or types...

Humans will turn the planet into a giant ball of fire by the year 2600, said physicist Stephen Hawking.

Overcrowding and energy consumption will render Earth uninhabitable in just a few centuries, Hawking said via video on Sunday at the Tencent WE Summit in Beijing.

Hawking types that humans better start looking for a new planet to settle down and ruin...

Good name for a sports team, the Fighting Hawkings.

Wow, he thinks we’ll last that long at the rate we’re going? He’s an optimist.

I don't know about the specifics of how long we have but I do believe that if we want to sustain our species a time will come when we will need to find other worlds to spread out onto.

Party like its 2599

Does he not know that during the Mesozoic era the CO2 concentration in the atmosphere was 10x larger than today?

I think just the sheer rate of population growth is a bigger issue than CO2.

Any discussion of just about ANY hot topic- AGW, economics, violent crime, nationalism, etc etc etc cannot be taken seriously without a concurrent discussion about what we are going to do about population growth

I give us about 5 years...

Better figure out a way to travel (much) faster than light, because the nearest planet that even vaguely resembles earth is going to be thousands of light years away.

You believe that old Population Bomb bullshyt? That’s so 1968.

The life on earth at that time was suited for the CO2 in the atmosphere...
Almost nothing alive today is suited for that

66 Million years is a long time
583 isn't

God's going to need to intelligently design us faster now for that atmosphere
He can do it - we all know that... I'm counting on it

I agree with this. Population will be the biggest issue. Planet is only so big.

How much a difference does that make in average temperature? A single-digit amount in degrees Celsius? I don't doubt the possibility that CO2 emissions can be problematic and maybe change climate conditions faster than many living things can adapt, but the idea that the planet is going to be an oven like Venus or a "ball of fire" is silly nonsense.

Until Hawking says when the world will end, while pictured on the cover of Sports Illustrated, STFU.

It won't take that long IMO. We're due for some cataclysmic event, i.e. a meteor strike, supervolcano, or incurable disease. In the meantime people are living longer forcing more urban density, food supplies are struggling to keep up for developing nations, potable water is harder to come by (even in the western US), producing enough power is tougher, and we're burning through natural resources and rare earths at an alarming rate. By the time we have the technology available to move people off planet en masse we may not have the resources to build the vehicles.

We ain't leaving this solar system...
Our choices are our own moon and Mars... and that's it

We aren't built to be in space for very long periods - gravity is a huge part of our DNA
and leaving this solar system even at 100X the speed of light won't get us anywhere anytime soon...

Let's get to it. We should have been working on a Moon base awhile ago.

Earth is as close to perfect for harboring life as it gets. If we as a species can't find a way to persist here indefinitely, do we really deserve to persist at all?

Who says we haven't been?

If you resist to persist, I will be happy to assist.

I'm sure he'll figure it out. Faith for the win

I have a feeling the physics is going to be much more challenging than the physiology. You can use a centripetal force to create gravity. I have no idea how you travel hundreds of trillions of miles without basically having a voyage that will have to span generations, unless there's some property of space we don't know about that can be exploited.
