Planet good for another 1.75 billion years - they just discovered this?

I've been very remiss not to post for so long, and so much has been happening it's hard to know where to start, so you might think my choice is a bit strange. It's this article from Foxnews on the end of life of our good planet. The take-home point is that our planet might not be liveable all the way until the end of life of the Sun. This is because the Sun's heat slowly increases. From being maybe 30% cooler when the Sun first formed, it will end up maybe 30% hotter than it is now. This will mean the Earth will pass from the 'habitable zone' into the torrid zone, the oceans slowly evaporate, the Earth's natural thermostat fails, and the planet suffers runaway heating until all life is gone.

To give you the flavour of it, here is a short clip from the article:

Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates.

But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable. Somewhere between 1.75 billion and 3.25 billion years from now, Earth will travel out of the solar system's habitable zone and into the "hot zone," new research indicates.

Very interesting. The only problem is this is old, very old, news. In the "Tree of Life" book Gitie and I wrote in 2003 we discussed this very problem.
